Re: [PHP] Ensuring all links go to index.php

If you want all requests to go through index.php, then the .htaccess file would be something like: RewriteEngine On RewriteRule ^whatever/.*$ - [L] RewriteRule !\.(gif|jpg|png|css|pdf)$ /server_path/index.php The second line exempts the directory whatever and the third line starts by exempting direct requests for files ending with gif, jpg, etc. Then, index.php would examine $_SERVER[REQUEST_URI] to map the friendly URL to content by including files or redirecting with header().

Me too, but Windows IE has so many problems I find it necessary to also
have a Windows system to check things.
However, I do have a BrowserCam account and on remote access under
W2K, IE6 the page did show the animated gif, so it looks like it
works. But, BrowserCam didn't have an image to upload so I couldn't
test the complete operation. I suspect it works as wanted.
Hey, all I'm saying is that my test of something very similar did not

There is no need to hit the server for this. Simply include display:

it's not shown when the page initially loads. In the onsubmit for the

First of all, posting this once is enough. Second of all, I think the
problem here is actually a lot easier than it would look at first
glance :)
I noticed the following error:
Warning: fopen(ssh2.sftp://Resource id #10/[...]): [...]
Now, what you see here is that you suddenly have a
ssh2.sftp://Resource id #10. This is probably not the domain name
you're trying to connect to, now is it? :) That string typically
appears only when you cast a resource to a string (eg. a
mysql-connection, a stream, or whatever). So, looking at line 79, I
would guess that $sftp isn't a string which tells fopen where to find
the file to open, but instead is a resource which should not be there
at all.
Thanks for your reply. I apologize for the duplication. I posted until
I saw it show up, and I've only seen it once -- probably my gmail
account marking as spam, which I don't see because I retrieve as a POP
account with Thunderbird. I unsubscribed and subscribed with a
different email address and posted again.
Here's where $sftp is coming from:
$connection = ssh2_connect(copy-design.com, 22);
$sftp = ssh2_sftp($connection);
And from the examples I've seen, the correct syntax for opening a
handle is what I use on line 79:
$stream =
fopen(ssh2.sftp://$sftp/whatever.com:22/home/whatever/public_html/
flamingo/.$filename, wt)
The info at http://us4.php.net/manual/en/function.ssh2-sftp.php says
that ssh_sftp() returns an SSH2 SFTP resource, which is what I
figured Resource id #10 is referring to. From the manual example for
ssh_sftp:
$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');
$sftp = ssh2_sftp($connection);
$stream = fopen(ssh2.sftp://$sftp/path/to/file;, 'r');
Perhaps I'm being as inept with this code as I seem to be with my
email, but if the domain is whatever.com, and the file is located at
/home/whatever/public_html/flamingo/, and the file name is
test.txt, and I want to open the file (which doesn't exist yet) for
writing, what should I use if not
'fopen(ssh2.sftp://$sftp/whatever.com:22/home/whatever/public_html/
flamingo/test.txt, wt)'?

[PHP] ftp_put() problem
I'm trying to FTP a string value as a file without writing it to the

file from the server, ftp_fput() works:
$fh = fopen(test.txt, r);
$upload = ftp_fput($conn_id, $destination_file, $fh, FTP_ASCII);
if(!$upload) {
echo pFTP upload has failed!/p\n;
} else {
echo pUploaded to .$ftp_server. as .$destination_file./p\n;
}
But trying to avoid writing to the local server by using ftp_put()
instead, this does not work:
$source = This is a test file. This is a test file.\nThis is a test
file.;
$upload = ftp_put($conn_id, $destination_file, $source, FTP_ASCII);
I don't understand why ftp_put() isn't able to use $source as a string
value, but substituting ftp_fput() into the script and using a file
handle does work. I'm trying to avoid writing a file to the local
server just to be able to use ftp_fput().

[PHP] upload changes accented character
I've built a system which uploads a tab-delimited text file saved from Excel, then uses the text file to update a MySQL database. But when the text file contains an é character (confirmed by viewing in a text editor before uploading), the character is converted to some other weird character -- a capital Z with what looks like an inverted circumflex accent above it. This replacement character is stored in the database and output to HTML pages. It doesn't matter if I use htmlentites() on the data before storing in MySQL, the weird Z character is still what's written to the database. And I'm not able to do a string replacement to make it é again (or eacute;), because when I paste the weird accented Z character into a PHP file and save, the character is converted into } (a space and closing bracket). Perhaps this isn't a PHP problem, but can anyone point me towards a solution? Setup is PHP 4.3.2 on FreeBSD 4.10, Apache 1.3.27.

Re: [PHP] PHP editor
What I am looking for is something to work pretty fast, have code autocompletion (even for functions defined in the included files like zend does) and also code ident in a similar manner with zend studio I just installed Zend Studio because I was able to buy it through Adobe at a discount when upgrading GoLive. I've been comfortable working in the source editor of GoLive, and the new version has improved support for PHP, but I assumed moving to Zend Studio would improve my efficiency.

Re: [PHP] Re: Upload file field not working as a form element

When I use this in the insert into the value that is inserted into the database is Array, as opposed to the actual filename. The $HTTP_POST_FILES array works for me.

Re: [PHP] PHP REDIRECT

I assume by meta refresh tag, you mean this: meta http-equiv=refresh content=10;URL=http://example.org/; What most people seem to not realize, is that the http-equiv attribute is just a way to specify HTTP headers in a meta tag. This is handy when you want to do so in static pages, but PHP has a more proper way to specify headers: http://www.php.net/header This creates a real HTTP header, and there is no reason for any PHP developer to use a meta tag for this purpose. Well, how about this situation as a reason: You must do authorization, then force a file download, and you want to also display a link to the file with the typical click the link below if the download does not start automatically. I couldn't figure out how to display a page (after authorization), then use the PHP header redirect to force the download while keeping the same page display. However, using a meta refresh to a script that forced the download (without producing any display) was an easy solution.

header('Refresh: ...');

Is this right? I suspect that you might be comparing these instead:

Your suspicion is correct, as pointed out earlier by Stuart. Thanks to both

[PHP] Can PHP redirects be detected?
A recent thread on the WebDesign-L raised the question of whether search engines can detect (and penalize sites for) PHP redirects of the form: header(Location: http://www.whatever.com/;); I don't see how that could be the case, since the redirect occurs on the server before any HTML is output to the browser. Someone else says: No, the header() redirect immediately tells the /client/ to make a second GET request at a different location and the client (search bot) must actively make that 2nd request to the Location: URL (what happens if you request amazon.com) Note this is different from simply sniffing the UA string from a single request and serving altered content. What say you, PHP list? Would it be better (in terms of search engine detection) to use include() to serve different or altered content?

Would it be better (in terms of search engine detection) to use include() to serve different or altered content? Do neither. Create excellent content, structured well, and the search engines will reward you for this. Try to trick them, and they will likely figure it out and penalize you. I'm not interested in tricking search bots. However, for the sake of user-friendly URLs, I use mod_rewrite to send most requests to index.php, then based on the request string I include() different content. I wanted to verify that wasn't creating a problem with search engines. However, if you're asking whether or not Google can determine if you're using include() to serve up different content based on the UserAgent or perhaps the IP address, then no, bots can't figure that out. Unless they switch useragents/IPs and compare the results that they get. Or unless a human complains that the listing is innacurate. etc...

Re: [PHP] Need a way to automate user logout
I used cron to do this as well; but i devised a much simpler, elegant solution that is cross-browser and event-based and not schedule-based. I basically have a javascript include file that instantiates a function that counts down in T-minus 10 minutes fashion. at 9:30 the browser pops a window and says you appear to be inactive; would you like to continue working? clicking on yes closes the popup and resets the timer; not clicking expires the popout which redirects the parent page to the logout. clicking on log me out basically circumvents the 30-second countdown straight to the logout. to handle the alt+F4-happy crowd i devised a way to pop a special logout window when the browser is closed. this child window destroys sessions and makes database logs; this window closes itself. this happened to work for me, YMMV. ~phillip jackson I've recently faced a similar issue. I lock CMS database records during editing so multiple users can't edit simultaneously. It's easy to unlock the records via PHP if the user goes to any other area of the CMS or if she logs out. The problem is that users often don't log out, and sometimes leave directly from an edit screen. I tried using the Javascript onunload event to open a new window which runs a PHP script to unlock the record then close itself, but that doesn't work if pop-up blocking software is being used.

I need to implement database record locking and unlocking.

Ok, will try to pass a value without the space in between.
RewriteRule ^show/(.*)/(.*)/(.*).php
/show.php?category=Beginners%20Cornersid=$2id=$3
It doesn't look like your rule would match. Try:
RewriteRule ^show/(.*)/(.*)/(.*)
Another way to achieve a similar result without using Rewrite is to parse
$_SERVER['REQUEST_URI'], and possibly $_SERVER['PATH_INFO']
Eg if your link is:
http://www.rizkhan.net/articles/show.php/Beginners%20Corner/1/1
Then $_SERVER['REQUEST_URI'] would contain
/articles/show.php/Beginners%20Corner/1/1
and $_SERVER['PATH_INFO'] would contain
/Beginners%20Corner/1/1
Ryan,
I'm doing what I believe Jason is indicating above. I'm sure in your
research you read the articles about URL rewriting on A List Apart,
specifically this one: http://www.alistapart.com/articles/succeed/. Using
a similar approach, I'm saving page content in a database with the unique
identifier set to the desired value of $REQUEST_URI. After redirecting all
requests to index.php as described in the article, I use code in index.php
similar to what's in the article, plus this for the database content:
-
// check for database content
$conn = db_connect();
if (!$conn) {
$db_error = mysql_error();
include(error_page.php);
exit();
}
// get the page details from db
$request = substr($REQUEST_URI, 1);
$results = mysql_query(SELECT DisplayStatus FROM Pages WHERE
MenuPath='$request' AND DisplayStatus='Y');
if (!$results) {
$db_error = mysql_error();
include(error_page.php);
exit();
}
if (mysql_num_rows($results) 0) {
include(page.php);
exit();
}
// if request has not been matched, include custom error page
include(notfound.php);
exit();
-
That pulls page content based on $REQUEST_URI. I build site menus from the
database, using values from the MenuPath field as URLs.

Re: [PHP] Rename generates level 2 warning but works
I have this magical script which uses rename. A visitor to the site uploads a file and I want to rename it to a timestamp. Oddly enough, the rename() function actually works, it renames the file AND then generates a level 2 warning: Error code: 2 Error message: rename() failed (No such file or directory) Why does it work AND create a warning? Here's the snippet of code: $rename = time(); $old_name = $_FILES['uploadedFile']['name']; $read_extension = explode(., $old_name); $ext = $read_extension[1]; $new_name = $rename...$ext; rename($old_name, $new_name); I know I can suppress the the warning with @, but I'm more interested in WHY this warning gets generated. I'm using PHP 4.2.2 on a Linux box. Any hints or suggestions are greatly appreciated... Try using $HTTP_POST_FILES['uploadedFile']['name'] instead.

Unfortunately, it didn't resolve the issue. Still getting the warning AND the rename function works. Odd indeed... Thanks, Roger OK, well how about this -- you said your code is: $rename = time(); $old_name = $_FILES['uploadedFile']['name']; $read_extension = explode(., $old_name); $ext = $read_extension[1]; $new_name = $rename...$ext; rename($old_name, $new_name); And your error message is rename() failed (No such file or directory), but isn't $_FILES['uploadedFile']['name'] the original file name before uploading, whereas $_FILES['uploadedFile']['tmp_name'] is where the file was uploaded to on the server. So the first is just a name, and the second is the file location. Also, you're defining what $new_name is before you even use rename(), so even if rename() fails, you've set the desired value for $new_name. But what you have not done is actually move the uploaded file. If it's being uploaded to /tmp, it will be deleted when your script ends. So, I think you need to pass rename parameters that are file locations. HTH -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Structuring keyword searches
I'd better apologize at the outset as I'm not sure this is strictly a PHP problem - though I'm using PHP as the means of building the application. Anyway, here goes: I'm creating a website that will function as a directory of services within a specific area of the UK charity sector. A variety of groups will input the content via a custom built CMS and this content will then be available to the general public. One of the requirements is that a keyword search facility is built into the application allowing end users to search for services based on a variety of words they might associate with them. What I propose to do is have a separate table of keywords/phrases that have been previously entered by contributors. There will then be a separate table linking the id field of the associated keywords with the id field of the service in question. Herein lies the problem. The contributors will be presented with a multi-part form. When it comes to the stage at which they will need to enter the relevant keywords for a service there seem to me to two ways of dealing with this: 1.Allow the contributors to enter whatever keywords and phrases they wish. 2.Only allow contributors to have access to a restricted set of keywords/phrases. The first of these options would run the risk of creating an unmanageably large and devalued set of keywords/phrases. The second option would seem to result in a set of keywords that are too generalized to be of much benefit to the ultimate end users. Are there any accepted approaches to tackling such a problem which anyone could point me towards? I'm sure it must have been encountered before though I've been unable to find much on this after extensive googling and searching through mailing list archives. I like the Luke Welling, Laura Thomson approach for keyword searching described in PHP and MySQL Web Development -- http://www.lukelaura.com. The system described is your option (1) above, and allows the keywords to be weighted by the contributors.

Re: [PHP] PHP Dynamic menu building
Dear list,
I have been facing problems while building dynamic menu. I am using
database to store the Menu items. I am having two fields in the database
table called ParentID, ChildID.
ParentChild
10
20
30
41
51
61
73
83
94
108
I want to build menu from this. Please suggest me the way to do so.
Thanks in Advance
The following will build a two-level menu as an unordered list, with the
second level appearing if its parent is selected. The variable $gpid is
grandparent id for a third level, which is not displayed in this menu. Some
checks are done in order to display a menu item differently if it is the
current page or an ancestor of the current page. (In the design I took this
example from, third level menus are shown in a different place.)
// build menu array
$menu_sql = SELECT id, parentid, menuname, FROM pages;
$menu_result = mysql_query($menu_sql);
if (mysql_num_rows($menu_result) 0) {
while ($menu_row = mysql_fetch_array($menu_result)) {
$menu_array[] = array($menu_row[id], $menu_row[parentid],
$menu_row[menuname]);
}
}
// home id is 10
$id = isset($_GET[id]) ? $_GET[id] : 10;
$pid = isset($_GET[pid]) ? $_GET[pid] : 0;
$gpid = isset($_GET[gpid]) ? $_GET[gpid] : ;
// display menu
echo(ul);
foreach ($menu_array as $menu) {
// if the parent id is 0, menu item is main level
if ($menu[1] == 0) {
if ($menu[0] == $id || $menu[0] == $pid || $menu[0] == $gpid) {
echo(lia class=\selected\ href=\ . $PHP_SELF . ?id= .
$menu[0] . amp;pid=0\ . $menu[2] . /a);
foreach ($menu_array as $menu2) {
if ($menu2[1] == $menu[0]) {
$subcount[] = $menu2[1];
}
}
if (count($subcount) 0) {
echo(ul);
foreach ($menu_array as $menu3) {
if ($menu3[1] == $menu[0]) {
if ($menu3[0] == $id || $menu3[0] == $pid) {
echo(lia class=\selected\ href=\ .
$PHP_SELF . ?id= . $menu3[0] . amp;pid= . $menu3[1] . \ .
$menu3[2] . /a/li);
} else {
echo(lia href=\ . $PHP_SELF . ?id= .
$menu3[0] . amp;pid= . $menu3[1] . \ . $menu3[2] . /a/li);
}
}
}
echo(/ul);
}
echo(/li);
} else {
echo(lia href=\ . $PHP_SELF . ?id= . $menu[0] .
amp;pid=0\ . $menu[2] . /a/li);

Re: [PHP] Sessions, ending and starting new with just a click
Hey guys and gals, I am working on a shopping cart and using some code to write it from 2 temp databases to a full end databases (which will then be used via PERL to send to an archaic order system) but right now I need to come up with a way to clear their current session ID after finalizing the order and then dropping them into the new session variable so they can start a new order. Why do you need to start a new session? Why not record the order to the database with a unique identifier, and then just empty the shopping cart? If they do a new order, you can give it a different id when saving to the db. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Session Expiration Problem....
Our hosting company sets session vars to expire every 15 minutes. I've setup an Admin Center for users to enter various types of information, some of which, for example entering a basketball team roster, can take slower users upwards of 25 minutes or more. The result? Admin user spends 25 minutes entering data; clicks the submit button; then is redirected to the login page because their session expired! -- all form data is lost -- not good Is there a way to extend the php session timeout for particular pages? Alternatively, is there a way, other than using cookies, to store user data from page-to-page? Thanks for any leads, Yeah, I get occasional complaints about this problem -- although I don't have to contend with sessions expiring every 15 minutes! I've found that it's usually possible to use the browser back button to return to the form with all values still in place (Windows 98-IE6 being an exception), then open a new window to log in again, then return to the form window to submit. Those instructions can accompany your not logged in message. Admittedly an inelegant solution, but it's better than losing the form data. In my situation, I've considered rewriting the PHP script that's receiving the form post so that if the session has expired it will re-display a simplified version of the form (without showing protected content) with the posted data, and provide a link to open a login form in a new (small) window.

Re: [PHP] Quick ereg_replace question
I need a regular expression which will eliminate all characters except
numbers, period, and +, -, *, or /
I am currently using:
$new_value = ereg_replace('[^0-9\.-/+*]', , $value);
However, this seems to eliminate - as well. Any help would be appreciated.
Try listing the - as the first character (or last) so it's not seen as
showing a range.
Also, any good references for regular expressions?

Re: [PHP] Having fits with input to array
I have a series of commands like so (with different programs on each line):
display_pgm(bash);
Here is the bare bones of the function 'display_pgm':
function display_pgm ($pgm) {
$cmd = -C $pgm --no-headers -o
pid,fname,state,vsz,start_time,flag,user,cputime,args --cols 200;
$ps = `ps $cmd`;
$ps2 = ereg_replace(\n, ,, $ps);
eval(\$psArray = array(\$ps2););
print_r($psArray);
}
If I can't get this part to work the rest of the function is a no-go. When I
do this I get only one element in my array instead of the 3-4 I should be
getting. I'm using bash for testing since I know that will always give a
return.
I've also tried:
eval(\$psArray = array(\$ps2\););
and
eval(\$psArray = array($ps2);); - This one gives me a parse error
(Parse error: parse error, unexpected T_STRING, expecting ')' in
/var/www/html/ps.php(25) : eval()'d code on line 1)
When I have used the same eval in another page I get each part separated by
the comma as a separate element in the array. What in the world am I doing
wrong?
For $psArray to be an array, shouldn't it be:
eval(\$psArray[] = array(\$ps2););

Re: [PHP] Mailing List
I would like to setup a mailing list for my company. I have a database containing email address of my clients along with other details. How can I send them mails ? If i write a script containing the mail function and loop the address, I think that might generate a script timeout error. I feel increasing the script timeout is not a good solution. I would like to know how you manage such situations. I feel this is a common problem but i didnt find any solution on the net. Do I need to use any sw or are there any already available scripts. I built a queuing system to email to a large list. The general approach is to add a database table that stores the email message and tracks progress through the list. A PHP script called by a crontab checks the database to see if a mailing is in progress. If so, it selects a certain number of addresses and sends the message. By controlling the number of addresses selected and how often the crontab calls the script, the email rate is controlled. And using a crontab makes it a background process. The email message is created and list progress monitored through a content management system. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Sessions
I checked the session settings with phpinfo(); I get the following values:
session_save_path = /tmp
session.use_cookies = On
session.use_trans_sid = 1
I've created a folder on the same level as all the pages called
ccb_sessions and have CHMOD it to 777.
I have added the following snippet above session_start: ?php
session_save_path(/ccb_sessions);?
When navigating to my test page I get the following error:
Warning: open(/ccb_sessions/sess_bbbfa69631155d4097e0b0012c857c4a, O_RDWR)
failed: No such file or directory (2) in
/home/.paco/campuscb/campuscorkboard.com/MemberAccountDetails.php on line 2
Checking with my FTP client that file is there and has CHMOD values of 777.
I've done a Google search for No such file or directory, found a bunch of
stuff for Python, nothing for PHP.
[snip]
Other ideas?
I think you need to provide a full directory path. I looked at my code and
here's exactly what I do. First, I include some functions with a
require_once() statement. One of the functions is prepath():
function prepath($url) {
$prepath = ;
if (substr_count($url, /)) {
for ($i = 1; $i substr_count($url, /); $i++) {
$prepath .= ../;
}
}
return $prepath;
}
That lets me use the same statement in different directories. Then the page
actually starts like this:
require_once($req_fns);
session_save_path(prepath($PHP_SELF) . ../ccb_sessions);
session_start();
Note that when I said my session data directory is on the same level as my
publicly viewable files (public_html), I mean that the session directory is
not contained within public_html, but is outside it at the same directory
level on the server.

Re: [PHP] Sessions
I'm trying to track down some issues with my site, and am trying to decide if it's a session variable issue. On a random basis, it appears that session vars are being dumped, deleted, or unset, as the site will break. Queries based on session vars don't work, session vars not being displayed, etc. This seems to happen most often after a page has been idle for a couple of minutes and a refresh is done on the page. This is on a hosted site. I have checked the configuration settings with phpinfo(); and session support is enabled. On all pages where I use $_SESSION[varname], I have ?php session_start();?. This has been double checked. 1) Do session vars timeout, or can they be set to timeout after a certain length of time? 2) Is there anything other than session_start(); that needs to be done when using session vars? 3) What other things can I check for? Most things are explained well by the online manual, and you should read and re-read the session documentation. That said, I'll also say that the documentation on sessions is not as informative as I'd like it to be, and I still get reports of sessions expiring before they should. Look at the output from echo phpinfo() and check these session configuration options: session.cookie_lifetime -- should be 0, lasts until quitting the browser session.use_cookies -- should be on session.use_trans_sid -- should be on Some things aren't explained very well, like what does session.gc_maxlifetime mean? The maximum time before garbage collection to remove session data that hasn't been used? But to minimize the chance of garbage collection on a shared server wrecking your sessions, you can specify a directory for saving session data. Create a directory (on the same level as your directory of publicly-viewable files if you can) and before the 'session_start();' line, do 'session_save_path(../my_sessions_dir);'. Also be aware that circumstances on the client side can mess with session cookies and cause the session to be lost, like using Internet Explorer with Entourage in Mac OS X. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Session info stored on server
What's actually stored on the server when using sessions? I've built a content management system on a commercial host, PHP 4.3.2, Apache 1.3.28, and use session_save_path() to specify a directory. When someone logs in, I check the username and password against the database, and save username as a session variable -- $valid_user = $username; session_register(valid_user); If I examine the directory specified by session_save_path(), I see something like sess_4f5d...0367. Where's the session variable valid_user? Is it an array element of sess_whatever, or are session variables stored in memory with only the ID stored on the server? A related question -- I thought that by specifying a directory with session_save_path(), the session data would not be subject to garbage collection. However, when I examine the directory specified, I don't see any creation dates more than 24 hours old, and I know there have been instances where the Mac OS X Entourage/Internet Explorer bug have caused sessions to fail, so the user never logged out, and session_unregister() and session_destroy() were never called for those sessions.

Re: [PHP] Web server file perms || More than I can chew.....
On my local machine (win2k pro, apache), no problems -- everything works just as designed. Today I began testing on the live server; i.e. my client's hosting company (linux, apache 1.3.27, php 4.3.1) -- that's when the trouble started. The site builder app builds static pages based on changes made by users in our online administration center. When I test out creating a new site section; i.e. triggering my make_file function(writes page content to new file) I receive the following error: Warning: fopen(/local_server_path/file_to_create.php) [function.fopen]: failed to create stream: Permission denied I've attempted to chmod(777) my testing directory via ftp client, which appears to work; however, when I fileperms($file_in_test_dir), I get chmod(644), so clearly I'm not the owner. Pardon my ignorance here, but I as yet know little about dir/file perms. Should I contact the host and have them give me sufficient permissions? If you create a subdirectory of the root level public HTML directory, then PHP can create files there, but not in the root level directory. If you change permissions to 777, PHP can create files there, but it's not a good idea to have the permissions that wide-open. You might be able to get your commercial host to change who PHP is running as from nobody to your login identity, then PHP could write to the root level directory, but you might not be able to -- my main host says they're changing policy for security reasons to not allow that. You could put the static files in a subdirectory where PHP will have permission to create files. But this might require lots of reworking links depending on your site design, and thus not be a viable option. You could set up a PHP script to be executed by a crontab as a CGI. Done this way, PHP can write to the root level directory. This is what I did recently for a similar problem. The content management system provides a link for updating static HTML pages. That link (script) writes info to the database, flagging an update request. Every 5 minutes, a crontab calls the PHP CGI script that actually does the update. The script checks the database flag and does the updates if they've been requested (flagged). Bottom line -- discuss the problem with your commercial host and see what they suggest. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Is there an issue using sessions with IE/Mac?
I've built a log in system which sets the user's id as a session if succesfully logged in. However, a user on IE5/Mac tells me that the site logs her out even though she has entered the correct login details. I have tried using her details on Firebird/Windows and have had no problems. Are there any known issues using php sesisons with IE5/Mac? For what it's worth (which may not be much), I've heard reports of problems with IE5.2 in OSX when used with Entourage.

[PHP] Creating files in public_html
My commercial host is changing policy so that PHP can't create files in public_html. This screws up my content management system, which generates static HTML pages which are hit a lot. Is this policy common? Is it a security risk for PHP to be able to create files in the main directory? (I have no problem creating files in subdirectories.) I've spent a couple days rewriting to use a PHP script called as a CGI to do the updates, and now they're telling me that that won't work when called from the CMS -- I've got to call it from a crontab, which I don't think will be acceptable. This is my third post concerning this (rephrased and refocused each time). Does anyone else need to create and update files in their main directories? Is this a security problem? Do I need to completely rewrite the CMS to use a subdirectory? -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] How to exec PHP as CGI
My PHP script for updating some static HTML pages no longer works on a commercial host that changed their setup so PHP can't write files to the public_html directory. The host's tech support says that a PHP script executed as a CGI can still write to public_html. The site has PHP 4.3.2 on Apache 1.3.28, with passthru, shell_exec, and system disabled. I'm not sure how to approach converting my script to work as a CGI -- if I need to execute the update from a content management system link, do I use exec()? Does exec() take a Unix command? If so, would that command just reference my PHP script headed with #!/usr/bin/php -q? And how do I return something to tell me if execution was successful? I'm searching through the manual, but links to good examples (or outright explanations) would be greatly appreciated. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] PHP permissions problem
My commercial host is set up with the public root directory, public_html, owned by user: userid, group: nobody. Directories I create within public_html are owned by user: userid, group: userid. As a result, PHP does not have permission to create files or write to files in public_html, but it does within its subdirectories. Is this a common setup?

Re: [PHP] problem passing variable between forms.
I have a form in which I have a table with dynamic checkboxes, they are in a checkbox array ( name = chk[]...), I pass this variable to the next page using POST I receive the variable and use it, no problem, but then when I try to pass it to the next form in the URL (using an A HREF: a href='confirmrequest.php?requested= . $chk .

[PHP] PHP and directory permissions
I developed a script which updates some static HTML pages. The script creates temporary files and opens them for writing. It then reads the HTML content of PHP-generated pages and writes that to the temp files. If that's successful, it copies the temp files to the static files, thus updating them. This worked without problem for several months, but recently started throwing a permissions error: Warning: fopen(temp_list_auctions.html): failed to open stream: Permission denied in /home/williams/public_html/generate_auction_lists.php on line 55 Unable to open temporary file (temp_list_auctions.html) for writing. The same script still works fine in public_html/dev, which is a directory I use for testing. I asked the commercial host why this has become a problem and why it works in public_html/dev but not in public_html. Here's the reply (which does not explain why it once worked): The reason the problem occurs in the public_html directory is because the directory is owned by user: williams group: nobody. Your account is setup like this so no one can write into your root directory, except a perl script or a PHP script on your site executed as a CGI. By chmoding the public_html directory to 777 you make the ownership settings useless. The directory named dev is owned by user: williams group: williams so your PHP script has no trouble writing to it with 757 permissions. So you could either chmod the public_html directory to 777 or we could chown the directory to user: williams group: williams. I don't want the public_html directory set to 777, but I certainly want PHP to be able to update files. Is there a security problem with having public_html owned by user: williams, group: williams? Would it be better to rewrite my script so that it doesn't need to create files? Comments on the best approach for security and reliability would be appreciated. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Problems send MIME multipart/alternative mail with php
I have had no success sending multipart/alternative emails with php. I have
tried everyone's various code snippets with no luck. I test the results with
Outlook and Outlook Express. Everytime my boundary tag ends up showing as
part of my message and thus the plain text and html portions show up as one
long blob of unformatted text. Below is the code I am currently using. Any
suggestions would be greatly appreciated.
Thanks,
Dan
The code:
?php
error_reporting(E_ALL);
//FUNCTION future
multipartmailer($to,$from,$subject,$plaintextsource,$htmlsource);
//$boundry=**=-=-=D-=-=-=-MIME-A-Boundry-=-=-N=-=-=-**;
$boundry= ---=.uniqid(MAILDIVIDERS);
//set mime type
$headers=From: Person [EMAIL PROTECTED]\n;
$headers.= MIME-Version: 1.0\n;
$headers.=Content-Type: multipart/alternative;
boundary=\$boundry\\n;
//these files have the raw message content
$plaintext = file(plaintextcontent.txt);
$html = file(htmlcontent.txt);
//warning for non-MIME lovin' clients
$headers .= This message is in MIME format. Since your mail reader does not
understand this format, some or all of this message may not be
legible.\n\r\n\r;
// CHOP
$message .= $boundry.\n;
$message .= Content-Type: text/plain; charset=ISO-8859-1\n;
$message .= Content-Transfer-Encoding: 8bit\n\r;
foreach($plaintext as $line) {
$message .=$line;
}
$message .=\n.$boundry.\n;
$message .= Content-Type: text/html; charset=ISO-8859-1\n;
$message .= Content-Transfer-Encoding: 8bit\n;
foreach($html as $line) {
$message .=$line;
}
$message .=\n.$boundry.\n;
mail([EMAIL PROTECTED],Welcome to the Website,$message,$headers);
print $headers..$message.br;
?
/body
/html
I also had a very hard time sending HTML-formatted email as multipart.
Following are some code samples from what eventually worked for me. I think
you can have lots of variations in the headers without problems, and that
your main problem is how you're using the boundary. VERY IMPORTANT: Note how
I'm adding -- before the boundary when it's used to separate things, and
how the last use of the boundary is followed by another --.
// define a boundary strings to use in multipart email
$OB = =_OuterBoundary_000;
// set multipart/alternative headers
$multiheaders = From: $from_name$from_email\n;
if ($reply_to_email != ) {
$multiheaders .= Reply-To: . $reply_to_name . .
$reply_to_email . \n;
}
$multiheaders .= Return-Path: $from_email\n;
$multiheaders .= X-Mailer: PHP4\n;
$multiheaders .= MIME-Version: 1.0\n;
$multiheaders .= Content-Type: multipart/alternative;\n\tboundary=\ . $OB
. \\n\n;
$multiheaders .= -- . $OB . \n;
$multiheaders .= Content-Type: text/plain; charset=us-ascii\n;
$multiheaders .= Content-Transfer-Encoding: 7bit\n;
$multiheaders .= Content-Disposition: inline\n\n;
My code samples are all chopped up because they're part of a queuing system.
I create a plain text message and an HTML-formatted message and write
everything to a MySQL database. A separate script that's called by a crontab
actually sends the email. (That let's me control frequency and volume.)
After pulling from the database, I build the multipart message from the
plain text message, the boundary, some more specific headers, the
HTML-formatted message.
// build multipart/alternative
$multipart_message = $message . \n\n-- . $boundary . \n .
Content-Type: text/html; charset=us-ascii . \n . Content-Disposition:
inline . \n\n .
html_entity_decode($html_message) . \n\n-- . $boundary .
--\n\n--End--\n\n\n;
if ([EMAIL PROTECTED]($fullname$email, $subject, $multipart_message,
$multiheaders)) {
// some stuff for error checking
}
Hopefully you can decipher my example.

Re: [PHP] Mail From option in PHP.ini
From the php website, it appears that the [EMAIL PROTECTED] can be put in the fifth parameter of the mail() function: Example 3. Sending mail with extra headers and setting an additional command line parameter. mail([EMAIL PROTECTED], the subject, $message, From: [EMAIL PROTECTED], [EMAIL PROTECTED]); Note: This fifth parameter was added in PHP 4.0.5. Since PHP 4.2.3 this parameter is disabled in safe_mode and the mail() function will expose a warning message and return FALSE if you're trying to use it. I followed this recent thread with some interest, because I'd like to be able to set the return-path header for a script that emails to a large list, which would in turn allow me to identify bounced emails. I'm using a shared host server, with PHP running as the master account user name, so the return-path for emails is something like Return-Path: [EMAIL PROTECTED]. I had accepted that I could not change the return-path value with PHP, but reading about this fifth parameter renewed my hope that I could. I tried adding a fifth parameter to mail() in order to do this, like so: // fifth mail() parameter to set envelope sender $cmd_line_param = [EMAIL PROTECTED]; mail($fullname$email, $subject, $message, $headers, $cmd_line_param); This didn't change the return-path header. Perhaps the problem is that I have no idea what the syntax of the command line parameter is (what the -f does). Can anyone advise? Is it possible to use this fifth parameter to set the return-path header, and if so, what's the syntax?

Re: [PHP] multi file multi colomn
I have 40 text files.. each files have 1 colomn of a data. I want to write a
script to merge them like
datafrom1;datafrom2;datafrom3;datafrom40
how can I do that?
Assuming that by 1 column you mean each file has data, then a new line
character, then data, then a new line character, etc., you could read each
file into a variable:
$data1 = ;
$file = (path to the file);
$fp = fopen($file, r);
if ($fp) {
while (!feof($fp)) {
$data1 .= fread($fp, 1024);
}
}
fclose($fp);
Then make each file an array by exploding on the new line character:
$records1 = explode(\n, trim($data1));
Find the size of each array as you make them (if they have different sizes,
track the largest size value somehow):
$num_records = count($records1);
Then concatenate:
for ($x = 0; $x $num_records; $x++) {
$merged_files = $records1[$x] . $records2[$x] . (etc) . $records40[$x];
}
If you need the data separated with semicolons, add them when concatenating.

Re: [PHP] Formatting issue.

I'm having a bit of a formatting issue, and I was wondering if someone
might have an idea on how to solve it. Basically what I have right now
is a script that opens and reads the content of an image directory, each
time the script is accessed it writes the contents out to a text file
for me. I then open that text file and read it's contents, I want to be
able to display thumbnail versions of the pictures, 3 per row and as
many rows as needed. Unfortunetly, all I can do right now is 1 per row,
this is where I need the help. Here's the code that displays images:
$dat=$_GET[gallery].dat;
$file=fopen($dat, 'r');
$contents = fread ($file, filesize ($dat));
fclose($file);
$img=explode(|,$contents);
print table width=50% cellpadding=0 cellspacing=3 border=0;
foreach($img as $image) {
if($image) print trtda href=$imageimg src=\$image\
width=150 height=100/a/td/tr;
}
print /table;
So how do I make this work so I can have three cells per table row and
it actaully show the proper picture?
You need to set up a counter so you can start a new table row at the
appropriate time. Beginning from the line where you use explode(), and for
brevity not writing out the HTML for linking the image:
$img = explode(|, $contents);
$img_count = count($img);
$i = 0;
foreach ($img as $image) {
if ($i%3 == 0) {
echo(trtd$image/td);
if ($i+1 == $img_count) {
echo(/tr\n);
}
} elseif ($i%3 == 1) {
echo(td$image/td);
if ($i+1 == $img_count) {
echo(/tr\n);
}
} elseif ($i%3 == 2) {
echo(td$image/td/tr\n);
}
$i++;
}
Hope this helps.

Re: [PHP] mailing forms and input into MySQL
From: Scott Miller [EMAIL PROTECTED]
I have a current php script that allows me to add/remove customer information
from a particular MySQL Database. What I would like to do, is when an
employee adds a customer, have some (if not all) of that information e-mailed
to a particular e-mail address.
I've created scripts that e-mail info, and ones that just enter info into a
database, but have not attempted combining them.
Anyone have any ideas, or is anyone doing this? If so, could you give me a
quick how-to or point me in the direction of some online documentation?
There's nothing tricky about it. Just do the database insert and then send
the email. I suggest returning a simple success/failure from the database
insert so that if it fails you can note that in the email (probably going to
a site administrator). I build strings for $subject, $headers and $message
(from the values that were used in the insert) like so:
$message = SUBMITTED:\n\n;
$message .= First name: $first\n;
$message .= Last name: $last\n\n;
$message .= Address: $address1\n;
if ($address2 != ) {
$message .= Address: $address2\n;
}
etc.
Then send it and report failure or success to the user like so:
if ([EMAIL PROTECTED]($send_to_name$sendto, $subject, $message, $headers)) {
// report failure to send confirming email
} else {
// thanks for submitting

Re: [PHP] sessions terminating randomly please help
From: freaky deaky [EMAIL PROTECTED]
i am experiencing a major problem with sessions expiring randomly in some of
my
apps. i will log in and start clicking around and then i will eventually
arrive at a page that tells me that i'm not logged in anymore. this happens
apparently randomly. i have seen it on ie6, ie for mac, netscape 4.7 for pc,
and mozilla
the apps are hosted on
freebsd 4.7-release p2
apache 1.3.27
php version 4.2.3
compiled with --enable-trans-sid
i can't go into production if there's the possibility that users will be
randomly logged off. i went through all of my code over the weekend, and i
don't think i can attribute this to a miscoding:
when a user logs in, i create a session with
session_start();
$valid_user=$_POST['username'];
session_register(valid_user);
i have the following code at the top of each page to check to see if the
session
is valid:
session_start();
$valid_user=$_SESSION['valid_user'];
global $valid_user;
if (session_is_registered(valid_user)
{...function to spit out an error message if the session is not valid...;}
i have a logout page that destroys the session
session_start();
session_destroy();
i also have a javascript timer in the header of every page that redirects to
the
logout page if the user has been inactive for 20 minutes.
i have played around with session.gc_probability, setting it to 100, but that
doesn't seem to have fixed the problem.
this is a huge problem.
if anyone can give some advice, i'd really appreciate it.
Is your session.save_path set to /tmp? It's my understanding that you should
specify a directory for saving session data -- or use a database -- that
/tmp is subject to garbage collection, and specifying a directory prevents
that. I made this change to a site recently. In tests prior to the change
the session would last up to about 2.5 hours with no activity. After
specifying a directory with session_save_path() right before
session_start(), the session was still OK after almost 4 hours of
inactivity. (Not much of a controlled test, I admit.)
That said, here's a disturbing fact that turned up last week -- a designer
working on the same site was continually being logged off unexpectedly.
After many tests he identified that the problem was Microsoft IE/Entourage.
Every time he checks email he's no longer recognized as logged in (Mac OSX
IE). He got Microsoft tech support to duplicate the behavior and confirm
it's a problem with IE -- doesn't happen with Mozilla.
So, it's important to verify the problem with more than one system, but it
sounds like you have since you mention both IE6 and IE Mac!

Re: [PHP] What solution to use for mass newsletter mailing reporting?
In my case the client's list is about 1500 addresses and they send every 2-3 weeks. The client wanted a way to recover if sending failed mid-list -- a way to know where to pick up again. A post to the list described a queuing system similar to the one I built, so check the archives if you end up building one yourself. In my preliminary tests it took much longer to send emails than 250 in 15 seconds! Sending test batches of 100, I got ranges from 27 seconds to 202 seconds, with the average time about 73 seconds for 100 emails. During these tests I was writing a counter to a flat file each time through the loop, which probably slows the process down a little, but I don't think that would account for the dramatic differences in speeds between your tests and mine. About bounce backs -- on the commercial host I'm using, each domain comes with web mail accounts. The default user for the account corresponds to the account username for FTP access. Other usernames/passwords can be added and can receive email at [EMAIL PROTECTED]. By setting up the crontab to execute as a specific user, that user email address is listed in the email header as the return-path and bounced/undeliverable email goes to that user email account. Someone at the client company monitors that address, verifies the bounce, and manually removes the address from the list.

Re: [PHP] What solution to use for mass newsletter mailing reporting?
From: J J [EMAIL PROTECTED] What do you use for mass newsletter mailing say for 5000+ members every month? At the same time, I'd like to be able to track who opened the message, any links they clicked inside the message, bounced messages, etc. I keep seeing reports that PHP/mail have trouble sending more than a few hundred messages depending on the machine. But for mass mailings you get into majordomo, etc, which seems to bulky for my needs. Any thoughts or suggestions on possible solutions? Thank you in advance! This general question is asked often, and I found lots of good information by searching the list archives. So check the archives, read the manual, read whatever articles you can find. (Check zend.com and sitepoint.com.) This will give you all the info you need to successfully send to a small list -- verify you can do that. Assuming you've got that down, here's a quick description of the system I built on a commercial Linux host using a MySQL database: - It takes several minutes to send hundreds of emails, so it's best done in the background. You'll need PHP available to run as a CGI/CLI called from a cron tab. - My solution is part of a content management system. Site administrators create the body of the email from database info. When a user hits the send button, the email is saved to a MySQL table which has fields for Time (time created), ListSize (number of addresses), Invalids (bad address formats), Attempts, and InProgress (an enum field used as a flag). There are lots more fields for storing parts of the message, etc., but that's not important to the approach. There's also a database table for storing the email address list, with fields for Time (same as the message table), Valid (valid format), Failed, Attempted, and TimeAttempted. - The cron tab calls a PHP script every five minutes which queries the database message table for fields where ListSize-Invalids Attempts and InProgress = N. If the result set is less than 1, the script exits. Otherwise, it sets the InProgress flay to Y and selects 50 email addresses from the addresses table where Attempted = N and Valid = Y and Time matches Time from the message table. - The sending PHP script then loops through the 50 addresses, and each time through the loop updates the address table for the address being processed, setting Attempted to Y, Failed to Y or N, and TimeAttempted to a timestamp value. After finishing the 50-address loop, the script updates the message table to set Attempts to a greater value and InProgress to N. - Finally, the sending script selects all completed messages (where ListSize-Invalids = Attempts and InProgress = N), orders the selection by Time descending, and deletes all but the most recent, and also deletes the Time-matching email addresses from the address table. This means that only active info and the last-completed mailing info is kept in the database. - Another nice thing about running the sending script as a CLI is that when a PHP script running as a module sends email, the return-path in the email header is listed as something like [EMAIL PROTECTED] and bounced email isn't accessible. (This is true on the commercial host I'm using, anyway.) But when the PHP script runs as a CGI, the return-path can be set to the user and the bounces are accessible. - Using the info stored in the message table and address table, I can produce a report on a mailing attempt. I also built a pop up window that refreshes every few minutes so I can monitor the progress of sending to a large list. There are lots of other details, of course, but it took too long to describe the general approach -- whew! Anyway, for anyone struggling with this sort of thing, building a queuing system like this seems to work well, and I'm sure it would be safe to greatly increase the speed above 50/5 minutes.

Sure. You say in a following post:

effect of this function only lasts for the duration of the script.
I'm not using session_set_cookie_params(). The session.cookie_lifetime

I have a login function that checks username/password against database
values, then on the content management system index page I do:
if (login($username, $password) {
$user = $username;
session_register(user);
}
All pages within the cms have session_start(); following a require_once()
statement, output some HTML, then call check_valid_user(), shown below:
function check_valid_user() {
global $user;
if (session_is_registered(user)) {

Re: [PHP] session expiration
From: 1LT John W. Holmes [EMAIL PROTECTED] I'm using sessions for authentication in a content management system and experiencing rare but occasional problems with the session apparently expiring unexpectedly. I've checked the manual and I've reviewed the session configuration on the commericial host I'm using. I don't see anything wrong, but there are some settings that I don't understand: session.gc_maxlifetime 1440 -- Garbage collection after 24 minutes? Does this mean that the session id and session variables will be cleared after 24 minutes of inactivity? (Surely not; that doesn't make sense.) And cleared from where, the directory specified in session.save_path? Yes and Yes. After 1440 seconds of not being accessed, they are deleted the next time the garbage collection routine is ran. So how did my tests of going up to 2 hours without activity succeed? session.save_path /tmp -- The session id and session variables are stored in this directory, and it's more secure to specify a different directory. Is it more stable to specify a different directory? Is it more stable to use a database? Depends on what else your server is doing and how much traffic you get. If you get a lot of traffic, there are going to be a lot of session files sitting in this directory. Keeping it separate from /tmp will just reduce the number of files in the directory. A database adds to much overhead and is only needed in special cases, IMO. session.cache_expire 180 -- The cache expires after 3 hours? If session.cache_limiter is set to nocache, is session.cache_expire relevant? Not sure on that one, but it seems logical. Basically, I want users to be able to stay logged in to the content management system indefinitely, but my tests show that after about 2 hours of inactivity, the session expires. (Going to a different page causes the session variable that identifies the user to be checked with session_is_registered(), and access is denied if the variable isn't registered.) Some users have reported this happening after about 30 minutes. Garbage collection isn't exact. It's triggered (by default) on 1% of the hits to your site. So if two are triggered close together, then someone can be logged out rather quickly at 30 minutes. If there is a long pause where the probability just doesn't trigger the garbage collection, then it may take longer. I'm on LInux, PHP 4.1.2, session.cookie_lifetime setting is 0, session.use_cookies setting is On, session.use_trans_sid setting is 1, and other configurations as mentioned above. Why are sessions expiring? Comments and directions to more information are appreciated. Sessions are lost when the file is cleaned up by garbage collection or when the user closes the browser (by default). So, if you wanted to use the existing session handling routines, you could set the cookie lifetime to a large value so the cookie isn't deleted and set the gc_maxlifetime to a large value, also. You could possibly turn the gc_probability to zero, go garbage collection is never triggered. Another option would be to use session_save_path() within your application to save the session files to a separate directory that's writable by the web server. Since this directory is different from session.save_path specified in php.ini, garbage collection will never occur, so the files will not be deleted. This seems like the answer I was looking for. So the setting session.gc_maxlifetime only relates to garbage collection from the /tmp directory? If I use session_save_path() to define a different directory for saving session data, then garbage collection will never occur for that directory? You can also define your own session handler to do what you want. Why not just use a cookie to remember me though, instead of keeping the sessions persistant? You're going to end up with a file on your computer for _every_ person that visits the site and the file will not go away. Seems like it'd be better to just use a cookie and load their data if it's not already present, like on their first visit. This is for a content management system, with less than 10 people authorized to access it, so I don't see the number of session files as a problem.

Try using trim() on the value to get rid of blank spaces, returns, and other weirdness. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] returning results of cURL POST
I'm using cURL to POST form fields to a PHP script on a different server
that does a database insertion. I know the POST is working, because the
values are being inserted into the database. But I want to return results
from the remote server so I can tell if the insert was *not* done.
Here's the relevant part of the sending script:
$ch = curl_init();
$remote_url = http://www.whatever.com/scriptname.php;;
curl_setopt ($ch, CURLOPT_URL, $remote_url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $field_values);
ob_start();
curl_exec ($ch);
curl_close ($ch);
$curl_results = ob_get_contents();
ob_end_clean();
// check cURL results
if ((trim($curl_results) != 1) || (trim($curl_results) != 0)) {
// maybe nothing returned, bail out
echo(pCan't confirm results of attempt to add to database!/p\n);
exit;
}
Here are the relevant parts of the receiving script:
// return notice if connection fails
if (!$db_connection) {
echo 0;
exit;
}
...
// return notice if database insert fails
if (!$db_connection-execute($insert_sql)) {
echo 0;
exit;
} else {
echo 1;
}
The receiving script doesn't display anything and should only echo as shown
above. I don't get how to return success or failure from the receiving
script. The information I've been able to find on cURL doesn't clarify this.
Can anyone shed some light?
Thanks.

I knew I'd find a stupid mistake as soon as I posted the question. I was
using a condition that could never be true, instead, I needed:
if ((trim($curl_results) != 1) (trim($curl_results) != 0))
Sorry.

Re: [PHP] tracking bulk email
From: Kevin Stone [EMAIL PROTECTED]
- Original Message -
From: Lowell Allen [EMAIL PROTECTED]
I've added an email feature to a content management system that will send
plain text email to about 1400 contact addresses. Each contact is sent a
separate email with the contact name and address in the To: header. It
works fine to small test lists, but hasn't been tested with a large list.
Although I think list posts should only pose one question, I have two:
(1) My client is nervous about the script failing mid-list and not being
able to determine which contacts were sent mail. I need to build this
check into the content management system. I could write a flag to the
database every time mail() returns true, but that would mean 1400 database
updates! If I instead append to a variable each time through the mail()
loop, I'll lose the record if the script times out. Can anyone suggest how
to record the position in a loop if a time out or failure occurs?
(2) In order to avoid the script timing out, I'm counting the number of
mail() attempts and calling set_time_limit(30) every 50 attempts to
provide another 30 seconds of script execution time.
[snip]
In response to your first question. File stores are something a computer
does very very fast (might want to add some error catching to this)..
$i=0
while() {
count_index($i)
$i++;
}
function count_index ($i) {
$fp = fopen('count.txt', 'w');
fwrite($fp, $i);
fclose($fp);
}
Thanks, Kevin. I've put a counter in place within my mail loop. It seems to
slow the process, but perhaps not too much. And thanks to Mark McCulligh for
describing a system for sending about 1500 messages that's called with a
cron tab and writes to a db after each mail. And thanks to Chris Hayes for
pointing to relevant list archives. My system seems to be working, but it's
so slow that I'm going to look at using a cron tab and saving everything to
a database for easier reference in case of failure mid-list.

Re: [PHP] tracking bulk email
From: Leonard Burton [EMAIL PROTECTED] What about making the log a .txt file and not a database? Wouldnt that be quicker? [snip] Thanks, Kevin. I've put a counter in place within my mail loop.

My system seems to be working, but it's so slow that I'm going to look at using a cron tab and saving everything to a database for easier reference in case of failure mid-list. I'm not sure how the speed of flat file access compares to MySQL access; I assume for simple stuff flat file reading/writing is faster. Currently my system does use .txt files to store/record standard message intro text, standard exit text, reply-to name, reply-to address, list of addresses that failed, the actual contact list (which is pulled from a remote MSSQL server each time email is sent), and a counter of mail attempts generated while looping through the email list (thanks, Kevin). But if I do a version with a cron tab I'll store in MySQL instead, since speed really wouldn't be much of a factor for a process without user involvement, and for me it would be easier to manage. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Can anyone suggest a way to record the position in a loop if a time out or failure occurs? What's wrong with 1,400 database updates? Seems to me that's the most straight forward solution, easiest to recover from, easier for someone following your footsteps to work on later, and is what db's are for.. Have you timed it, and felt pain? You could email yourself 1,400 times to test, and see if it hurts. I haven't tried it from a database, no, and I don't know if the time requirement would be prohibitive. As it is, the best test time has been 0.186 seconds per email, and the worst has been 0.847 seconds per email (from about 4-1/2 minutes to about 19-3/4 minutes for 1400 addresses). I just *assumed* it would take longer to write to a db; I should compare. I certainly agree it would be easier to manage recovery from mid-list failure with everything stored in a database. -- Lowell Allen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
