Re: [PHP] Problems creating images
I added image confirmation to a guestbook and even though it works greate for most people, some people have problem and I can't seem to figure out why this happens. Note that I'm not talking about the same guestbook on one server but the guestbook is on people's own hosting server.

Re: [PHP] Strtodate() bug?
I've got some weird behavior using PHP 4.3.9. I use the function of
strtotime(last Sunday); and it's returning the timestamp for last
Saturday. However, if I use strtotime(-1 day); (I'm running this program
on a Monday) it returns the correct timestamp for Sunday.
Is this a bug in PHP 4.3.9?
Probably. 5.1.2 says:
$x = strtotime(last Sunday);
print ( date('r', $x) );
Sun, 02 Apr 2006 00:00:00 -0800
4.3.9 is *really* old.

Re: [PHP] Multidimentional array problems

What are you setting $arrayIndex to initially (before the while loop
starts?)

{
echo $banner[$value][url]. br;
echo $banner[$value][image]. br;

I only get the last set of values that where entered into the array. I want
to be able to pull all the values out

$banner[1]['url']
$banner[2]['url'] etc.

Re: [PHP] validating ereg patterns
How do I detect the difference between a bad ereg pattern and no matches? I've got a UI that allows the user to enter an ereg expression. Clearly, the user may enter an invalid expression (for example, the expression may not have matching [] brackets). ereg returns false if there are no matches or if an error occurred. I need to distinguish between no matches and an error, so I can present a meaningful message to the user. Any suggestions on how to do this? Maybe try preg_match.

Re: [PHP] $i vs. $r
I simplified the code a bit, and I am guessing that it was too much. Below is
the complete code that works fine. The weird part is, the part that I have
the question on, is if I change $r to $i, it doesn't work anymore. $i doesn't
count up as it should and instead gives me some unpredictible results. as
it goes down the list sometimes its sequential (1,2,3 but never more than 3),
other times its just the number 2 over and over).
$r = 1;
while ($row = mysql_fetch_array($website_result))
{
if (is_int(($r+2)/3))
{ echo (\ntr);}
echo (\ntd align=\center\ valign=\bottom\);
include($site_path/common/code/directory_format_name.php);
I'm going to guess that $site_path/common/code/directory_format_name.php
uses $i to do something else on it's own and is therefore messing up your
$i. At least that's where I'd start looking.
// Gets the name Formatter
echo (\na href=\/directory/.$row['sup_link']./\img

echo (bra

Re: [PHP] Security in php/ajax scripts
I am slowly converting my webapps to use the 'ajax' technology. I'd like to know what 'best practices' should I use when it comes to authenticate, identify the requests in a more restricted context. So far I've migrated some 'open' areas where the user, without having to identify himself can perform searches. But I need to allow/deny him to do insert/delete/update actions. In the traditional webapp I'd create a login page where the user. password would be checked against a database and a session variable would be set with a authenticate code. Further access to restricted pages are allowed/denied based on the existance of this authenticate code. What would be a good alternative in my ajax-enabled webapp? I cant use session in my php scripts (those called by the XMLHttpRequest.open) right? Why not? Not that I've tried it, but your browser is going to be making the call and I would imagine it would send along any cookies it has just like it normally does...

Re: [PHP] GD2 gif resizing problem

Re: [PHP] Hostname Filtering
I have a few PHP scripts where I log hit to a page i.e. IP and hostname via a look up. What I want to do is create essentially a blacklist to prevent bots and other hosts and IP from being logged and skewing my stats. My local IP/host and the MSN and Googlebot hits should not be in my stats or at least I can flag them to hide them. For example: $blacklist = array( '*.wavefront.ca', '*.googlebot.com', 'msnbot.msn.com', '*.inktomisearch.com', '68.146.96.245' ); So lets say I have my host: $host = 'lj602144.inktomisearch.com'; I want to quickly parse this array and return a simple boolean if I am in the blacklist. I could create a loop and cycle through the array valves and to a regex on each but I was hoping someone would have a more elegant solution. http://us3.php.net/in_array You might want to rethink things though... if you list hostnames you're going to have to do a DNS lookup for *every* request to that script.

Re: [PHP] Sessions in PHP... where to start???
Hi everybody! I have a problem and I was told to check out the sessions part in PHP. What I want to deal with is the following : I have a PHP page with a form, where the user writes some data. These data are then written into a file which is then used in a system command as input for an external program (NOTE: The data MUST be written into a file, it cannot be done elsewhise, because the external program takes a file as input). The thing is that I must somehow create a file everytime a user enters data into the form, so I must learn something on sessions I think. My question is, since I don't have a login system or something like that, but just want to create a different file each time (with the session_id being part of it, so that the file is unique), which session commands do I need? If it were me I'd use tempnam() to create a unique file for that particular user and then use sessions to store the name of that file in the user's cookies... http://us2.php.net/tempnam http://us2.php.net/manual/en/ref.session.php -philip -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The problem I believe is with the defined function check. (I think) the

running the if() statement, but it's not.

$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($fileContent);
imagecreatefromjpeg takes a *filename* not the actual contents of the file
itself. So $image is going to be invalid so your next command isn't going
to do what you think which means you're going to get black as that's
probably the first/default color of $image_p.

Re: [PHP] Reading large files via PHP?
I'm reading in a 66MB file into php so I can parse it and load it into a
database. However, it is taking a long time for php to read the file.
So long that the script times out. I know about the
ini_set(max_execution_time, 120) or whatever length I want to set the
time out for the script, but my question is as follows.
Is it possible to read in a file and at the same time echo out a status
of how far along the file has been read?
The code I have right now is below. Just wondering if what I'm trying
to do is possible and how to do it.
// set script timeout
ini_set(max_execution_time, 120);
// import file name
$log_file_name = access_log.1;
echo Reading access log!br/;
if (!$ac_arr = file(./$log_file_name)) {
echo Couldn't load access log!;
die;
}
Thanks!
Even if you get around the execution time the above code is going to use
up 66megs of memory to store that file in $ac_arr.
You'd be much better off doing something like:
$fd = fopen(./$log_file_name, r);
while ( !feof($fd) ) {
$buf = fread($fd, 32768);
// process buffer here
}
fclose($fd);
That will let you do your progress thing as well as not eat up so much
memory. Play around with values of 32768 to see if smaller or larger
makes any different on your system.
Good luck!

Ahhh.. Okay that's very cool and I did not know that. I knew that it
was chewing up a lot of memory reading it all at once.
I guess the only thing I have to worry about now is if I do a read like
that will it truncate a whole line instead of getting the whole line?
The reason why I ask is that if possible I would rather have it read
line by line for X lines and then process that buffer then go and grab
more lines until end of file. Is that possible?
Sure. If it's a text file you could do something like this:
$i = 0;
$buf = ;
while ( !feof($fd) ) {
$buf .= fgets($fd);
if ( $i++ % 10 == 0 ) {
// process buf here
$buf = ;
}
}
Or you could turn buf into an array with $buf[] = fgets($fd) if that's
easier...
All kinds of options :)

Re: [PHP] Strange problem with overlapping names
the page shown below works fine on my own machine, but on another (remote)
server, it gives me a strange result.
Here's what happens: The first time I view the page it says array(0) { }
as I'd expect, but on the second it says object(kurv)(0) { } where I
expected another array. The problem seems to be that the object has the
same name as the key in $_SESSION -- if I call it $foobar the problem
disappears. But that explanation doesn't really make much sense to me.
As I see it there's something wrong on the server. Can anybody tell me
anything about this problem?
Compare the output of phpinfo() on your machine with the output on the

Re: [PHP] duplicate filenames but different .extention
hello again
I am trying to figure out how i can read the list of files in a directory
using the opendir() and readdir() functions. Normally this goes fine but
within the loop, what i am wanting to do is echo the filename if it is a jpg
file, but if its a .gif, just continue.
I have several files i wish to seperate based on the basename of the file.
i read the basename help file and know how to use it even to exclude the
.3letterextention. I am however wanting to skip if it happens to be a .gif,
is there some sort of way to i guess, do the basename function in reverse,
e.g if it comes across xx.gif it would skip it but not skip over the
xxx.jpg files?
that is my latest problem, it skips everything when i have a line like this
in my loop
if($file = basename('.gif',$file))
continue;
else go on with code
if ( ereg(\.gif$, $file) ) {
continue;
}
would do it.. so would
if ( substr($file, -4) == .gif ) {
continue;
}
Don't forget about .GIF though if that might be an issue for you...

Re: [PHP] Accessing photos outside the web folder
I'm writing a content management application which saves file paths in a database and allows users to search the database for those files. Problem I'm having is that although the PHP script that handles the database queries works fine, when the search results get to the browser, all the paths are off limits. I can't just move the photos inside the web folder as we're talking tens of thousands of images that are already organized into a folder structure that must be maintained as is. Is there a way to allow the web page to see these photos? The images are stored on a Windows box and all the web server stuff is on a G5 Macintosh running OS 10.4 3 (in case that has any bearing on the matter). Depending on security issues you have two options. Put a webserver on the Windows box and modify your search results to link to the images using something like this: img src=http://windowsbox/getimage.php?path=/path/to/img.jpg; Then put a getimage.php script on the windows box that does something like: ?php readfile($_GET[path]); ? If you can't (or don't want to) put the windows box on the internet, then still do the above and then also do the same on the mac. Assuming the mac can get to the windows box.

Re: [PHP] Handling competing edits in a wiki engine?
I've recently been working on building my own wiki engine for my blog site. While the majority of the engine is complete, a remaining concern I have is how to handle competing edits (ie when two or more people are editing the same wiki page simultaneously). I'm wondering if anyone else on the list has given this some thought? How would / do you handle competing edits to the same entry in a wiki application? Just to add a little extra information: all 'edits' are in fact 'inserts'. Entries are stored in a mysql table. The engine simply displays the most recent record for the entry being viewed. This is, of course, to allow for retrieval of an historical version of the entry should one or more entries be vandalized. Seems like you have a couple of choices. 1 - Lock the page when the first user edits it until they save their changes. Has the advantage that it's pretty easy code-wise. The disadvantage being that if that first user leaves, but doesn't save/cancel his edit, how/when do you decide to release lock? This would be similar to how Visual Source Safe or RCS does it. 2 - Allow shared edits and programatically merge the changes back into the master document. This is how CVS does it. So you could do something like this: - user A starts editing document. - user B starts editing document. - user A saves his changes. this copy is now the most recent as the system would check to see that no changes were made to the master copy while user A was making changes. - user B saves his changes. the system would see that the master copy had been updated and would merge the changes into B's copy and save that. In this last step you could do it a couple of different ways. When user B saves his changes, the system could create a diff file between the most recent version of the document and the one that was the basis for B's changes -- this would be the changes user A made. Then you could merge those changes into B's document. If there was a conflict (ie. user A and user B made changes to the same line) user B would have to resolve the differences. This is exactly how CVS handles it. Or, you could just create a diff file and make user B manually apply the patch until he's happy. If you have access to a unix box take a look at the 'diff' and 'patch' commands... good luck! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm working on a script which basically loads an image, the user requested and wonder how to properly sanitize the passed path.

Maybe I'm a little paranoid but is this really enough? For clarification: All paths are prefixed with some kind of a root path. All images within this root path may be accessed but jumping out of it should not be allowed. realpath() is your friend... prepend your root path to the passed in string, then run that through realpath, then verify that your root path is still prepended... http://us2.php.net/realpath realpath() expands all symbolic links and resolves references to '/./', '/../' and extra '/' characters in the input path and return the canonicalized absolute pathname. The resulting path will have no symbolic link, '/./' or '/../' components. realpath() returns FALSE on failure, e.g. if the file does not exist.

Not knowing exactly what you're trying to accomplish...
I'm guessing that your $filename file is 24113191 in size and that PHP is
compiled with a memory limit of 16777216. And since your assigning the
results of fread() to a variable, PHP is going to try an allocate that for
you and is failing.
Couple of points..
Why loop if you are reading the entire file at once? Which is what
fread($file, $fileSize) is going to do?
Instead perhaps you want this:
while ( !feof($file) ) {
echo fread($file, 32768);
}
(or some other value for 32768...)
That keeps the memory usage down, but does the same thing...

Re: [PHP] Problem with Internet Explorer when downloading / viewing dynamically generated PDF files
I have written a script which dynamically generates PDF documents (with PDFlib). The link to the PDF file is presented as a static link (thanks btw to Richard Lynch and his previous contributions to this list on the subject force download). It is redirected to the script via a htaccess file. If the name of the PDF document matches a certain pattern, than the script will output the document, if not, a 404 error page will pop up. Everything works very well with all kinds of browsers, except Microsoft Explorer (tested with Windows Explorer 6 SP1, Internet Explorer 5.2 for Macintosh). And I want to know why. Explorer shows the PDF document as plain text only. Trying to save the linked document to the computer (right click) gives something like The server can not be reached or the document does not exist. I know that explorer is a real p.i.t.a. when it comes to all kinds of web standards. And my best guess is that this could have to do with headers, or? A long time ago I helped out a buddy who had a problem with dynamically generated PDFs, but only certain ones. I don't remember all of the specifics, but this is what I do remember. What I remember is that it ended up only being a problem on PDF's that were larger than about 1mb -- but only for IE. We finally figured out that IE was beginning the download of the PDF itself, but if it downloaded more than about 1mb, it would pass it off to a helper application to do the rest. The thing was the helper application remade the request. But it wasn't passing along the form parameters used to generate the PDF so he was always getting a blank PDF (blank in the sense of generically empty). My memory is that the PDF was the result of a form POST submission and that changing it to GET fixed it, but he eventually kept the POST submission, generated the PDF, stored it on disk, and redirected to that.

Re: [PHP] Problem with Internet Explorer when downloading / viewing dynamically generated PDF files
These were all good suggestions, unfortunately none of them was able to solve my problem. I did a rather simple test to eliminate at least some of the possible causes. I changed the script in order to do three simple things: send a Content-type header, read an existing PDF document into a string, output the content and exit. This is working in Safari, Firefox and many other browsers. Explorer (both Mac and Windows) says 'no'! 'The file could not be found' Could it be that Explorer in some way don't accept redirects? But redirects are made on the webserver, right? I tried to figure out if some header information was Do you mean Header(Location: )? Those happen on the *client*. -philip send during the redirection. But echoing apache_request_headers and apache_response_headers gave no result. So, the question remains: what is causing Microsoft Explorer to fail on the download? Maybe the idea with static links isn't so good after all. I mean, if I do the same thing with a usual GET request, even Explorer won't make any trouble. But on the other hand, the PDF-generating-thing is supposed to be on an other server than the webserver. And I don't like to expose this server to the Internet. Any ideas are still welcome! /frank 2005-09-22 kl. 18.55 skrev Steve Lefevre: Philip Hallstrom wrote: We finally figured out that IE was beginning the download of the PDF itself, but if it downloaded more than about 1mb, it would pass it off to a helper application to do the rest.

Re: [PHP] help out a noob w/ include switch?
Hi All,
My very first post to this group as I'm a freshly spanked new born php
baby. Hope I have the correct stop for noob tech questions. Please
re-direct me if I have it wrong. I've been doing web dev for a quite while
with a variety of methods (html, xhtml/css, cfml, flash/as, on and on...).
I work mainly for non-profit organizations and thought it was about time to
get away from commercial software. I'm doing my first site now w/ a
XHTML/CSS template that uses PHP to insert data from a switch container and
from a MySQL db.
My problem occurs only on the server (NT 5 b.2195, PHP 4.3.10, IIS 5.0) but
works great on my dev rig (XAMPP 1.4.15, VectorLinux).
My template index.php uses 'include' to get '$vars' from two files. one
for the body text and title, and the other for the navigation. Click on a
link in the navbar and index.php reloads with the new navbar and the
associated content each into it's div. Works great on my test rig but the
server the site will be hosted from ignores the urlencoded vars and just
loads the switch defaults. For whatever reason I tried return() instead of
break. Again, it worked on my rig but not the server. I know i'm missing
some dumb little thing but I have not figured out what yet. I also tried
session_unset() at the beginning of the index.php in case the problem was
with caching. Didn't work either but may be due to incorrect usage. Any
help or advice is very greatly appreciated!!
I'm guessing that register_globals is set to On on your dev box and Off on
your NT server. Check the manual for register_globals along with $_GET.
or if that fails, create a simple phpinfo() page on both servers and
compare the output to see what settings are different.

Is there a quick way to compare dates in the format dd/mm/yy without exploding and comparing the individual parts? Compare them in what way? Before, after, days between?

Re: [PHP] How large string in cookie?
How large can a string be in a cookie? (the value-parameter) According to here: http://wp.netscape.com/newsref/std/cookie_spec.html There are limitations on the number of cookies that a client can store at any one time. This is a specification of the minimum number of cookies that a client should be prepared to receive and store. * 300 total cookies * 4 kilobytes per cookie, where the name and the OPAQUE_STRING combine to form the 4 kilobyte limit. * 20 cookies per server or domain. (note that completely specified hosts and domains are treated as separate entities and have a 20 cookie limitation for each, not combined) Servers should not expect clients to be able to exceed these limits. When the 300 cookie limit or the 20 cookie per server limit is exceeded, clients should delete the least recently used cookie. When a cookie larger than 4 kilobytes is encountered the cookie should be trimmed to fit, but the name should remain intact as long as it is less than 4 kilobytes. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Inserting records question
Still learning, so sorry if this sounds really simply noobish. But as I understand things currently this should work. But doesn't. I've been looking over tutorials but just don't see whatever the problem is. I created a simple table with the following fields (in order) tc_id (auto nmbr) lname fname machine_name email_addr problem date_time_submitted (timestamp) And I'm trying to run this insert from form input. $username=somename; $password=somepass; $database=somedb; $table=sometable; mysql_connect(localhost,$username,$password); @mysql_select_db($database) or die(Unable to Connect to DB); $tc_query = INSERT INTO $tablel VALUES(NULL, $lname, $fname, $machine_name, $email_addr, $problem, NULL); $result = mysql_query($tc_query); mysql_close(); So what exactly do I seem to be missing here? A lot of single quotes... around the parameters you are inserting... add in a print($tc_query) and see what that looks like... run that directly in mysql and it will give you more details on the error. Or, make it look like this: $tc_query = INSERT INTO $tablel VALUES(NULL, '$lname', '$fname', '$machine_name', '$email_addr', '$problem', NULL); I'd also suggest you read this page: http://www.php.net/mysql_escape_string good luck! -p -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Stripping control M character (^M)
Hello All,
I'm having some issues with carriage returns. Specifically the control M
character (^M). I have attempted to clean and validate the file I'm
creating. Here's the code.
while ($row = mysql_fetch_array($result)){
// assign and clean vars
$artist = trim($row[artist]);
$tdDate = trim($row[start_date]);
$venue = trim($row[venue]);
$city = trim($row[CITY]);
$state = trim($row[STATE]);
$country = trim($row[COUNTRY]);
$tdId = trim($row[td_id]);
// create string
$line = $artist|||$tdDate||$venue|$city|$state|$country|$tdId\n;
// validate the string
if(preg_match(/.*.|||.*.||.*.|.*.|.*.|.*.|.*.n\//, $line)){
// record is correct so write line to file
fwrite($handle,$line);
}
}
So ^M slips right by trim and my preg_match line.
Where is the carriage return appearing in your line of output? Trim
will remove these, but only at the beginning/end of a string so if $artist
= Paul\rNowosielski that won't get cleaned up...
Maybe run them through ereg_replace() using [\n\r] as a pattern?

Re: [PHP] intval() vs. (int)
On checking form fields that they are of type int, what is best to use: intval() or type casting (int)? In terms of speed, would (int) not be better, because we save a function call (especially on very large sql statements)? Time it. On an 800mhz box doing absolutely nothing else (it's just sitting there, honest :) a script which reads 100,000 16byte strings from a testfile (composed of a bunch of tar balls put together just to get something random) and then doing this: - loop through array doing $x = $array[$i] just to read it all in once. - loop through array doing $x = intval($array[$i]) - loop through array doing $x = (int) $array[$i] yields this (in seconds). nothing = 0.3619658946991 intval = 0.60399794578552 (int) = 0.48065304756165 So, for 100,000 random 16 byte strings you're saving 0.12 seconds or 0.012 per iteration...

Try some tests... start a session, load a page, and have the page reload itself every minute (being sure to access/modify the session).

You can.. Dont include the expire argument.. or set it to 0. You sure? The manual says (last sentence): expire The time the cookie expires.

Or you might use mktime(). time()+60*60*24*30 will set the cookie to expire in 30 days. If not set, the cookie will expire at the end of the session (when the browser closes).

hi i have a problem when i am formating a string the problem is it converts the \n in the string to a new line here is the code ? $Text = D:\AppServ\www\intranet\admin\store\nodirectory\sub; $Replace = D:\AppServ\www\intranet\admin\store; $with = http://localhost/bank/admin/store;; //$doc = str_replace ($Replace, $with, $Text); $doc = str_replace( '\\', '/', str_replace( $Replace, $with, $Text ) ); echo $doc; //i need $Doc to look like this http://localhost/bank/admin/store/nodirectory/sub //but it outputs http://localhost/bank/admin/store odirectory/sub Replace your double quotes with single quotes... that is: $Text = 'D:\AppServ\www\intranet\admin\store\nodirectory\sub'; $Replace = 'D:\AppServ\www\intranet\admin\store'; $with = 'http://localhost/bank/admin/store'; -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] weird results from imagettfbbox()
I have an array of strings in which I am passing to imagettfbbox() in order
to calculate the height of the text box for each string. I am then
subtracting the height from the y position in order to deviate the pivot
point form the top left corner to the bottom left corner when I used
imagettftext() to draw the text on an image. I am giving both commands a
fontsize of 50, an angle of 0 and I am using the font ARIAL.
I am having an issue where the first string comes back with a height of 50
and the next comes back with 47. Then 50 again for the next following
string and then 47 again for the next one foloowing that. It keeps going on
and on like this and I do not understand why. I am using the same font,
font size, and angle for each string so shouldnt they all come back as the
same size?
Is each line of the file the same? It's going to vary depending on what
letters are in the string (ascenders and descenders for letters like
qygpi, etc.).
maybe that's it?
Here's a snippet of what I am doing:
$file = this can be any file;
$im = imagecreatefromjpeg($file);
$textcolor = imagecolorallocate($im, 0, 0, 0);
$fontfile = arial.ttf;
$fontsize = 50;
$arr = split(CR, $_GET['text']);
$boxes = count($arr);
if (preg_match('/[0-9]/', $boxes)){
for($c=0;$c$boxes;$c++){
$text = stripslashes($arr[$c]);
$y = $fontsize * $c;
$bbox = imagettfbbox($fontsize, 0, $fontfile, $text);
$dy = $bbox[7] - $bbox[1];
$py = $y-$dy;
imagettftext($im, $fontsize, 0, 1, $py, $textcolor, $fontfile, $text);
}
}
header(Content-type: image/jpeg);
imagejpeg($im, ,95);

Re: [PHP] displaying certain number of character
$words= If length is given and is negative, then that many characters will be omitted from the end of string (after the start position has been calculated when a start is negative). If start denotes a position beyond this truncation, an empty string will be returned. ; echo substr($words, 0, 50); ? I have been using this but how can I make sure I do not split a word in half? - Finishing on a space would probably do it. You could use wordwrap() to wrap lines at 50 characters and then just take the first line http://us3.php.net/wordwrap -philip -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Sort table by column and pagination
We have quite a complex product all written in PHP and our own mySQL wrapper. We initially wanted to use smarty, but due to time constraints, we couldn't re-write everything, so it never got implemented. Two feature requests we get a lot are the ability to sort the tabular data by column heading (click once for ascending and again for descending) and the second is pagination. My guess is finding code that does this that you can integrate is going to take longer than just doing it yourself. It's not that bad... Just add some variables that either get kept in a session or passed around via URL's to store the $offset and $order_by. Then in your code set your $limit. Then it's just a matter of adjusting your SQL to add ORDER BY $order_by LIMIT $limit OFFSET $offset when relevant. For your array, it's the same thing, but use array_slice. To go to the next page just have the link set $offset to $offset + $limit. Similarly for previous. Then add the boundary checks, etc. Good luck! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] PHP vs. ColdFusion
It's too bad you have to use Windows and IIS. Just curious but why are they not wanting to use Linux? Do they know it's free and way less likely to be attacked? I've made this argument numerous times. Management seemed to be receptive, and I thought they were starting to change their Microsoft only attitudes, so the statement from my boss that management said it has to run on IIS really caught me by surprise. I think you might be going about this the wrong way... If I understand this thread correctly, your app *works* on linux/php. It breaks on windows/php. So it's working, right? Which is all they should care about, but they don't? So, write up a little document showing how much time (which equals money) you're spending trying to fix something that really isn't broken except in the eye's of management. This thread's been going on for a couple of days now. Assuming you've done nothing else for those several days and I've seen mention of discussing it with other engineers and sysadmins... just how much money has the company spent on this non-problem? Then since it also seems like you're not that much closer to solving the problem, estimate how much additional time it's going to take to fix it. Then show them the bottom line. That the company has spent $2,000 so far and will probably spend another $3,000 until it's fixed. Not to mention all your other projects being delayed. That's another $5,000. Ask them if this is worth spending $10,000 to fix something which isn't broken. Then be sure to tell them you will be happy to revisit the problem when there is *nothing else to do* I've had issues like this.. usually they want to know how long it will take to port our application from FreeBSD/PHP/PostgreSQL to Windows/ASP/SQLServer and when I tell them at least six months, probably a year, they decide maybe it's not worth it to satisfy someones need to say yes, we run on windows! (and yes, I know php,postgresql is available for windows now, but that's not the point) Anyway, might work... then again it might not. But it changes it from a technical discussion to a financial one which is how they think. good luck! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] parsing useragent string without get_browser
I've done a google and can't find anything on this. I want to parse a long list of useragent strings for a web analysis script I am writing. I could use get_browser, but firstly this would slow down my script quite a bit and secondly I am relying on the browscap.ini file of the newness of which is upto my ISP as I am on shared hosting. Is there are a way of doing this? I'd like to break down the string into it's componant parts but the difference in strings is big. eg- Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; stumbleupon.com 1.927) Windows-Media-Player/10.00.00.3650 Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4 Mozilla/5.0 (compatible; Yahoo!

Re: [PHP] syntax for two comparison operators
Is there a technical reason why PHP does not allow comparison operator
expressions like the following:
if (2 $x = 4) {}
I prefer this concise way as it is common for mathematics expressions, and
much easier to grasp physically on first glance. From what I can tell, this
expression can currently only be written as:
if ( $x 2 $x = 4) {}
I'm sure someone who knows more about it than me will chime in with the
real reason, but at first glance how would the interpreter interpret it?
Given 2 $x = 4, do you mean:
2 $x $x = 4
or do you mean
(2 $x) = 4
where 2 $x will evaluate to true or false. Doesn't make much sense as a
condition, but it's there...
Also, you could wrap it in a function if you find you use it a lot..
function between($x, $min, $max) {
return( $min $x $x $max );
}

Re: [PHP] Files passing through
Benchmark it both ways and see. I benched this with a 100 MiB text file (largest I could find at short notice). Buffer used for fread() calls was 2 KiB as above. Values are averaged over 100 runs (I would have liked to do more, but I don't have time). All values are to 4 significant figures. Thought it might be interesting to see what happens by changing the buffer size using the fread option. Hacked up your script to run 100 times for a variety of buffer sizes reading in a ~100mb file, writing it out to /dev/null. Each iteration would shuffle the buffer size array so that it didn't them in various orders (just cause). This is on a FreeBSD 4.x box 800mhz, scsi disk, completely idle. Looks like for my server, 32K is the fastest, but it also looks like it really doesn't matter much. And none of this was run through apache which might have an affect since it's going to cache data before sending it as well I expect.

Re: [PHP] Files passing through
What is the fastest way to do this? I know
echo(file_get_contents('myfile')); is not a good idea ;)
Why not?
My guess would be because file_get_contents returns the contents as a
string. So if 'myfile' is 100mb, you're going to have to allocate 100mb
of memory to store that string while echo() spits it back out.
But I'm just guessing as I don't know for sure...

Re: [PHP] Week Days
All you need is the mktime() command. do something like: $futureDate = date(Y-m-d, mktime(0, 0, 0, $month, $today+ $daysToAdd, $year)); Jordan http://www.php.net/mktime mktime() is useful for doing date arithmetic and validation, as it will automatically calculate the correct value for out-of-range input. For example, each of the following lines produces the string Jan-01-1998. ?php echo date(M-d-Y, mktime(0, 0, 0, 12, 32, 1997)); echo date(M-d-Y, mktime(0, 0, 0, 13, 1, 1997)); echo date(M-d-Y, mktime(0, 0, 0, 1, 1, 1998)); echo date(M-d-Y, mktime(0, 0, 0, 1, 1, 98)); ? All fine and dandy... but he said WEEKDAYS, so adding 5 days to a given day must non deduct from the 5 days when a weekend day is passed. This kind of calculation is useful for banks and other businesses that only process transactions on business days (which happen to be weekdays). Easy enough to change that date(...mktime(...)) command above to return the weekday and while the weekday is a weekend just add a day and repeat. that would give you the next monday. Holidays are another matter though, but that could be worked around as well via a lookup table... -philip -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Week Days
Easy enough to change that date(...mktime(...)) command above to return the weekday and while the weekday is a weekend just add a day and repeat. Actually sorry to post again on the same post, but this is like the first solution posted and is invalid since it doesn't account for non-weekdays that fall within the range. It only checks the endpoints of the addition. For instance adding 50 days would contain about 20 or so weekend days. Ah... but you are forgetting the rule I live by... anything that happened more than a week ago or is happening more than a week in the future... doesn't count, I don't remember, and I can't be held responsible for. :-) good catch though. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: previous + next buttons, no DB
Ashley, How are you creating the gallery page? You must be reading the filenames in the directory and producing an img for each one. Can you create an array of those filenames, save it to session (or generate it each time), and iterate through them? Say the images are in a folder called /gallery/ Within that, I have an index.php that is manually coded to have thumbnails of the images displayed in a grid. Important to note: they're in a very specific (artistic) order. Each one of those thumbnails is linked to one and the same popup.php file that is simply another php file that expects an $ID passed to it. That $ID, which again is hard coded in index.html, tells popup.php which file to display. (that $ID is basically the file name of the image, so I can append it to the img / tag as the page loads. So you see, I have no array of anything. The index.html file gets manually edited every time something is added or removed. This is why I'd like a programmatic way of a) generating that file, so that the client can add/remove images as they see fit, and b) be able to have prev/next buttons on the popup window. Change it. Remove all the hardcodings from index.html. Instead create another data file that contains the list of images (and the order) you want them displayed. Easier for you if that file is a PHP file that looks something like: $img_array = array( img1, img3, img2, ); But it could just as easily look like this: img1 img3 img2 Note that I'm only putting in the basename of the image, not the full name. Hopefully you can determine the path to the thumbnail and full image from this basename. If you can't make it look like this: img1thumb.jpg img1.jpg ... Then turn your index.html into a index.php file that includes (or processes) this data file. Now you've got an array you can loop through to display the thumbnails. Change your popup.php page to read that data file in as well. And now you can loop through it to find the image you're viewing. Keep track of a counter and if that counter is greater than zero, display a previous link. If it's less then the total count of the array minus one, display a next link. I'd take it a step further still and have each separate index.php include a master index.php (same for popup.php) so that the only thing a specific directories index.php contains is: include_once(/path/to/master/index.php); That way you can make global code changes without touching all the files.

Re: [PHP] one more mysql question

I can never remember the syntax, but you want to LEFT JOIN the tables and then only return rows where the resulting special_orders column is NULL. something like this (most likely wrong syntax): SELECT o.trans_no, s.trans_no FROM orders o LEFT JOIN special_orders s ON o.trans_no = s.trans_no WHERE s.trans_no IS NULL But that should get you started... -philip -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: possible bug (string equality to zero)?
No, Christopher, that is not a bug. As long as the var is empty, and if you try to compare with 0, or false, it will report true in the comparison because the variable does not contain anything, which will mean false for a boolean and 0 for a variable. If you are attempting to discover if a string contains data, use empty() instead. You can also check if the string is null or actual zero (0). But the var isn't empty. $a[] = 'blah'; $a[] = 'blah'; $a['assoc'] = 'array'; foreach ($a as $k = $v) if ($k == 'assoc') # do something The 'if' statement is incorrectly executing when $k is 0. I find it strange that 0 == any string. The way I see it, 0 is false. false == 'a string' should not be true. You might try === instead of == to get type checking as well... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
