AddModule mod_php4.c Additionally, does anyone know why the httpd processes are growing so big? This is common under mod_perl as it caches compiled code in memory, but PHP doesn't do this so I've no idea why the httpd processes are in the region of 35MB each. The only application we're running on these servers is phpBB. Possibly PHP is leaking memory? The reason why we didn't see this on our Fedora Core 1 servers is because the glibc on Fedora Core 3 reports these corruptions (whereas FC1's glibc doesn't). However, we do still see the 35MB httpd processes on Fedora Core 1. From the FC3 release notes: glibc The version of glibc provided with Fedora Core 3 performs additional internal sanity checks to prevent and detect data corruption as early as possible. By default, should corruption be detected, a message similar to the following will be displayed on standard error (or logged via syslog if stderr is not open): *** glibc detected *** double free or corruption: 0x0937d008 *** By default, the program that generated this error will also be killed; however, this (and whether or not an error message is generated) can be controlled via the MALLOC_CHECK_ environment variable. The following settings are supported: 0 -- Do not generate an error message, and do not kill the program 1 -- Generate an error message, but do not kill the program 2 -- Do not generate an error message, but kill the program 3 -- Generate an error message and kill the program Note If MALLOC_CHECK_ is explicitly set a value other than 0, this causes glibc to perform more tests that are more extensive than the default, and may impact performance.

[PHP] strange sessions
Hello, I'm experiencing a weird thing regarding sessions - that I'm using for user authorisation. I have a page that the public can view (index.php) that includes a login button. When the login button is clicked a new window pops-up and asks for username and password. The user is then logged-in. The parent page then detects using sessions that the user is logged-in and includes the text and link Joe Bloggs: [logout]. All the public content on this website is viewed via index.php. For example, a URL to about us or contact details may be index.php?keyword=about or index.php?keyword=contact. The a user is not logged in, all links within the page work fine, but when the user IS logged in, a hyperlink from one page to another page (whose URL contains a different 'keyword') doesn't work. The browsers address bar updates to reflect the new page, but the web page never changes (even when I physically type a different 'keyword' into the address bar). Changing physical files (ie. index.php to main.php) does work. As soon as I click 'logout' which destroys the user's session, everything returns to normal. Is there something I'm missing here?

Re: [PHP] $_REQUEST
Be carfull with this super var. This var is a merge of the GET, POST and FILES, and so only 1 index can only exists. If you have an index in the POST field called 'test' and also and index calles test in the FILES or GET var, than only one index of them is avaible and the other are gone I recommend to use the GET, POST and FILES var instead of the REQUEST var..

RE: [PHP] On large application organization [long and possibly boring]
[snip] Josh, I am interested in what you mean by but there may be a better overall approach. The reason I say that is because, though I'm no expert on application design, in my own code I've found that whenever I'm tempted to use a big switch, it's probably a better idea for me to make a class hierarchy. I just have a hard time imagining a case where a big switch accurately represents the problem to be solved, since in real life solving problems is more complicated than a flat set of totally isolated operations. [/snip] The switch in this case is being used by the application as you would a main() in C++ to a large degree. Here is an example error checking and validation (ECV) function / class is loaded at the top because it can be used for all switch cases; database connection module is loaded at top, it can be used for all switch cases form A is handled by case A. form A is unique in the tables that it utilizes. form B is handled by case B. form B is unique in the tables that it utilizes. and so on...perhaps 20 - 30 forms Also, the completion of form A may dictate that n more forms must be completed. The user completing form A needs only to see the forms designated during the processing of form A. In a couple of cases subsequent forms will require the successful completion of additional forms. The forms in this case are quite independent of each other from a processing point of view. They do rely on certain holistic items, such as ECV and DB connections that are also held in seperate files. As for management. Since there are several developers working on the project this method of management works quite cleanly. Each can complete isolated form coding without disturbing another developer's progress. All have applications flowcharts and have the hooks to the ECV API and DB connection API. If a module needs to be taken off line it does not affect the operation of the remainder of the application. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] mail() w/ postfix problem in Fedora Core 3
I've been searching for the solution to this problem to no avail. I recently did a clean install of FC3 on a server that was running RH8. There were a number of PHP scripts that I had configured to send out email for notices or passwords or the like. However, now that I've upgraded I can't send mail through the mail() command in PHP. My problem is exactly like what I found here, but unfortunately that question was left unanswerd: https://www.redhat.com/archives/fedora-list/2004-December/msg06708.html To summarize, I have no problem sending email via SMTP (one of the apps I run has the option to choose between using PHP mail() or using it's own SMTP client). Whenever I try to send mail with mail(), apache logs the following error: sendmail: fatal: chdir /var/spool/postfix: Permission denied Postfix logs nothing. I have checked the permissions on the /var/spool/postfix directory, and they seem to be in order: drwxr-xr-x 16 root root4096 Nov 23 05:11 postfix php.ini is configured with: sendmail_path = /usr/sbin/sendmail -t -i /usr/sbin/sendmail is a link to /etc/alternatives/mta which is a link to /usr/sbin/sendmail.postfix. All of these are world readable and executable. This setting is not overriden anywhere else (tested with phpinfo()). Does anyone know what's wrong and how to fix it? If not, is there a drop-in replacement for the sendmail command that will just forward the request to postfix via SMTP?

It's also possible that you've got your require's out of sequence somewhere in there. Personally, I always structure my code so that there is only one place where any given file will be require'd so I don't need require_once. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

NOFRAMES
Tons of stuff here -- the browser *could* be smart enough to start
loading them things up there before it processes all this...
/NOFRAME
/FRAMESET
Much less a bunch of JavaScript garbage here.
Another possibility would be to have the left frame do the loading of
variables, and have the frame on the right as loading. Then when the
left frame has loaded the variables, you can use javascript( using
document.frames IIRC) to load the right page. This way you can be sure
that the left page is loaded before the right page, since it is the
left page that actually does do the loading of the right page. Your
page is kinda screwed though if a visitor turns off javascript, like I
do when I have the displeasure of having to use IE on Windows.

I refresh the contents of main.hp at the end of left.php. (With help

My Question:
Is it ALWAYS so that left.php must be executed before the right frame

that
main.php is dependent of. So this session-variable must be set before
main.php is loaded.

I'll give you a simple case.
I have a GTK PHP MP3 ID3 editor application I'm working on.
When one opens a file in a directory, I provide next/prev buttons to
quickly page to the next/prev file in the directory.
Getting the next/prev to work is simple enough, but...
I've got the whole array built from opendir/readdir, and sorted it into

I've got a filename inside that array, from the pre-defined

So I need to initialize the internal array pointer to the position of the
file within that array, there is no such PHP function.
Why not change your structure? Sounds like you want a linked list,
better yet a doubly linked list. So create a double linked list class,
link up your entries, and keep a hash available for fast lookup into the
linked list where the keys are the filenames or whatever you want to use
as an index, and the value is a reference to the interesting linked list
node.
Given that scenario you will have a currNode object which is the
currently selected song, and when someone moves up or down the list you
just do something like:
if( $currNode-hasNext() )
{
$currNode = $currNode-next();
}
Moving backward would be as simple as:
if( $currNode-hasPrevious() )
{
$currNode = $currNode-previous();
}
And if the user selects an arbitrary file:
$currNode = $lookupArray[$index];
This kind of structure works a lot like a doubly threaded red-black tree
:) Although a red-black tree would keep your entries in sorted order
whenever you add new entries in O( lg n ) time.
Cheers,
Rob.

Uhhhm. Yeah.
I could spend hours finding/writing a doubly-linked list class, which will
be a good bit slower and WAY more memory-bloated than the built-in PHP
doubly-linked list (aka 'array') and, in theory, I could code it so that
the 'set_current' function existed and was maybe a bit faster than walking
the PHP array...
But every *other* operation would be a lot slower, and I only need to walk
the list to initialize the internal current pointer once, when the user is
already distracted and slowed down by the Open File dialog.
I think the user experience will be *much* better without all that, though.
if( $currNode-hasNext() )
{
$currNode = $currNode-next();
}
if ($current != $array[count($array) - 1]) $current = next($array);
Moving backward would be as simple as:
if( $currNode-hasPrevious() )
{
$currNode = $currNode-previous();
}
if ($current != $array[0]) $current = prev($array);
Actually, the buttons are disabled if you are on the first/last item, so
the checks for hasNext/hasPrevious are done elsewhere anyway.
And if the user selects an arbitrary file:
$currNode = $lookupArray[$index];
No, no, no.
The FileSelection already returns the filename.
Of course, I just *built* that array based on the directory they chose, so
could initialize the $current_index as the array got built...
So I'd need to keep an *INVERSE* array internally to do:
$current_index = $inversearray[$filename];
So then I'd be keeping track of the $current_index, at which point I'd not
even *NEED* to bother with next/prev and friends: I'd just have a global
variable for the integer index in the array, and play with that in PHP.
No bloated class objects to track something as simple as an integer from 0
to (count($array) - 1)
Maybe I'll just ditch the internal prev/next stuff and use $CURRENT_INDEX
as a global everywhere and write my own prev/next functions to do integer
arithmetic instead. Seems kinda silly when it's all already built-in to
PHP *except* set_current() but there ya go.
This kind of structure works a lot like a doubly threaded red-black tree
:) Although a red-black tree would keep your entries in sorted order
whenever you add new entries in O( lg n ) time.
You're comparing O(lg n) in PHP to O(lg n) in built-in C from PHP. Not
the same at all until we start hitting the kind of numbers that aren't
even useful for the number of files in a single directory.
I'm *not* going to set this box up to have 10,000 files in the same
directory. Puhlease!
The only time something is added to my tree is when they open up a new
directory, at which point the whole tree is re-built from scratch, since
it will have zero (0) elements in common with the previous tree.
As much as I love Object-Oriented programming, it amazes me what lengths
people will go to in order to use it no matter how inappropriate it may be
to the task at hand. :-)

I want the failure that require provides, but don't want to have to map out all these class file dependencies so laziness demanded require_once. :-) Still learning the quirks of PHP.

You're actually pretty close. What I would do is remove the dashes
from the equation and make that date a unique number. The advantage
of the date format you're using is that the date represented as a
number will always be sequential. So, if you do this:
$week1 = 20050110;
$week2 = 20050117;
$week3 = 20050124;
if(date(Ymd) = $week1)
{
echo this is week 1;
}
Now you'll have to create your logic in reverse, so that it will
trigger the latest date first, because every date from now until week
17 will be greater than $week1. So, something like:
if (date(Ymd) = $week17)
{
echo This is week 17;
}
elseif (date(Ymd) = $week16)
{
echo This is week 16;
}
etc.
Does that make sense?

$weeks = array (20050107, 20050110, 20050115);
for ($i = count($weeks) - 1; $i = 0; $i--)
{
if (date (Ymd) = $weeks[$i])
{
print This is week . ($i + 1);
break;
}
}
It counts backwards, since you'll want to test the latest week first.
You could count forward in the for loop if you create the weeks array
with the weeks counting down. I don't particuarly like having a break
in the loop, but it gets the job done. If you didn't have it in
there, you would see the print statement for every week that has
passed, as opposed to the current one.
Was this a better answer?

[PHP] Error in foreach?
Hello all; I have encountered a very strange error on one of our customers sites.

number. If you compare two numerical strings, they are compared as
integers. These rules also apply to the switch statement.

returned it by referencebut it's not very efficient :S
Why would you ever want to do that other than to waste cycles?
I'll give you a simple case.
I have a GTK PHP MP3 ID3 editor application I'm working on.
When one opens a file in a directory, I provide next/prev buttons to
quickly page to the next/prev file in the directory.
Getting the next/prev to work is simple enough, but...
I've got the whole array built from opendir/readdir, and sorted it into
alphabetical order.
I've got a filename inside that array, from the pre-defined
GtkFileSelection dialog.
So I need to initialize the internal array pointer to the position of
the
file within that array, there is no such PHP function.
Why not change your structure? Sounds like you want a linked list,
better yet a doubly linked list. So create a double linked list class,
link up your entries, and keep a hash available for fast lookup into the
linked list where the keys are the filenames or whatever you want to use
as an index, and the value is a reference to the interesting linked list
node.
Uhhhm. Yeah.
I could spend hours finding/writing a doubly-linked list class, which will
be a good bit slower and WAY more memory-bloated than the built-in PHP
doubly-linked list (aka 'array') and, in theory, I could code it so that
the 'set_current' function existed and was maybe a bit faster than walking
the PHP array...
But every *other* operation would be a lot slower, and I only need to walk
the list to initialize the internal current pointer once, when the user is
already distracted and slowed down by the Open File dialog.
I think the user experience will be *much* better without all that, though.
if( $currNode-hasNext() )
{
$currNode = $currNode-next();
}
if ($current != $array[count($array) - 1]) $current = next($array);
Moving backward would be as simple as:
if( $currNode-hasPrevious() )
{
$currNode = $currNode-previous();
}
if ($current != $array[0]) $current = prev($array);
Actually, the buttons are disabled if you are on the first/last item, so
the checks for hasNext/hasPrevious are done elsewhere anyway.
And if the user selects an arbitrary file:
$currNode = $lookupArray[$index];
No, no, no.
The FileSelection already returns the filename.
Of course, I just *built* that array based on the directory they chose, so
could initialize the $current_index as the array got built...
So I'd need to keep an *INVERSE* array internally to do:
$current_index = $inversearray[$filename];
So then I'd be keeping track of the $current_index, at which point I'd not
even *NEED* to bother with next/prev and friends: I'd just have a global
variable for the integer index in the array, and play with that in PHP.
No bloated class objects to track something as simple as an integer from 0
to (count($array) - 1)
Maybe I'll just ditch the internal prev/next stuff and use $CURRENT_INDEX
as a global everywhere and write my own prev/next functions to do integer
arithmetic instead. Seems kinda silly when it's all already built-in to
PHP *except* set_current() but there ya go.
This kind of structure works a lot like a doubly threaded red-black tree
:) Although a red-black tree would keep your entries in sorted order
whenever you add new entries in O( lg n ) time.
You're comparing O(lg n) in PHP to O(lg n) in built-in C from PHP. Not
the same at all until we start hitting the kind of numbers that aren't
even useful for the number of files in a single directory.
I'm *not* going to set this box up to have 10,000 files in the same
directory. Puhlease!
The only time something is added to my tree is when they open up a new
directory, at which point the whole tree is re-built from scratch, since
it will have zero (0) elements in common with the previous tree.
As much as I love Object-Oriented programming, it amazes me what lengths
people will go to in order to use it no matter how inappropriate it may be
to the task at hand. :-)
I was going to write a lengthy response to your berating, but then I
remembered you're a procedural zealot and the above comments aren't much
better than the bait on the end of a troll's line.

Re: [PHP] Comparison Operator
Ahh.. the trick question. hah.. Ok, let me see if I remember this (although it doesn't seem to follow the logic in my head.. I know someone else will explain it better but let me take a crack at it): When comparing a two different variable types that PHP thinks it knows how to compare, it will try. In this case, I believe the 'A' gets converted to a true/false type thing (0 or 1).. although I thought it'd convert to a 1 so you'd have if (1 == 0) which would be false. At any rate, something like that is happening and it's comparing values that you don't think you're comparing. Try using the triple equal sign operator (===) instead of the dobule (==). This forces PHP to not do the conversion.. to compare EXACT values. Using === means that 0 does not equal '0' because 0 is an int and '0' is a string. Someone else will give a better explaination soon, just wanted to give you something so you weren't stuck/frustrated/etc for too long. -TG = = = Original message = = = Could anyone tell me why this code echos? ?php $value = 0; $curval = 'A'; if ($value == $curval) echo WTH, Overbr; ? ___ Sent by ePrompter, the premier email notification software.

Try ===
If you use ==
$value is compared to $curval
$value is integer so
php converts $curval to integer
so it contains no digtis so
it assumes that $curval=0;

$value = 0 means false. And your comparison is false. Try:
If the comparison is false, the echo shouldn't be executed.
This if statement is evaluating to true, because...
If you compare an integer with a string, the string is converted to a

Re: [PHP] Error in foreach?
Sounds like $_GET isn't populated or has been over-written. Try doing the classic print_r on $_GET to see what it contains before you do the foreach. If you are using a form (rather than an a_href link) to pass the GET data and you're using all checkboxes or something else that returns nothing or doesn't set the GET variables, you might see if that's the problem. But yeah, print out the $_GET data right before the foreach and see what's in it. I'm guessing it doesn't contain an array because either no data was passed to the query string (is the PHP script in a frame and the parent frameset is receiving the GET data or something?) or it's been overwritten earlier in the script. I try to make it a practice never (rarely at least) to do a $_POST['something'] = somevalue or $_GET['something'] = somevalue. I like to consider those 'sacred' variables that are only set by a POST or GET form action (or an a_href tag in some cases of GET data). Once you start manipulating them in your code to 'fix' or 'adjust' them, then you run into issues where you may have overwritten your originally submitted data and you can get this kind of confusion.

RE: [PHP] Comparison Operator
The function this is from sometimes uses $_POST or $_GET input, so
sometimes its comparing 1337 with '1337' and === would break that.
so I'll have to use something like:

unless there is a better way

[PHP] Unique, hard session timeout on a shared server
I have researched a few ways to set a hard session timeout on a shared server. Does anyone have comments on the advantages/disadvantages of each approach? Are there other alternatives? 1. Override the php.ini settings in an .htaccess file: php_value session.gc_maxlifetime 900 php_value session.gc_divisor 1 php_value session.gc_probability 1 2. Put a previous request timestamp into the session, and compare it to the current timestamp on a request. 3. Set a meta refresh to a kill session script. Will there be a performance hit for all applications on the server under the first method?

Re: [PHP] does php ready for enteprise ?
One of the big arguments for PHP being ready for the enterprise is that, hey, Yahoo uses it! But it's more the reason why Yahoo uses it. Part of the reason is that PHP is scalable because of it's a shared nothing architecture, so you can scale it horizontally just about indefinitely. Plus it's a lot easier to develop in than Java or C++.

You practically wrote it already. Also you can use a for loop to load
the array of dates.

$d=11;
$y=2005;
//Load week array
$week= array();
for ($i=0; $i= 17; $i++ ) {
$week[$i] = date(Y-m-d,mktime(0, 0, 0, $m , $d + (7*$i), $y));

if ($today = $week[$i] and $today $week[$i+1] ){

Why doesn't it yield 403 like it should First and foremost, use php.ini or httpd.conf or .htaccess to *NOT* let PHP send error messages OF ANY KIND to the browser on a production site. [You could also use ini_set within a script if the file in question is to be include'd into other files.] You should do this anyway. Admittedly, your server still behaves not quite like you want, as *.html yields a 403 response, and *.php yields a 200 response, and a page of no content. But at least the Bad Guys don't see your server internals. I don't think there's any way you can configure Apache to pre-empt the PHP trying to read the file -- though I presume Apache *could* be altered to behave that way... Except it would be rather difficult for Apache to 'know' a priori what User PHP runs as, given suexec, CGI setups, etc... Depending on your application, you might be able to wrap all the access to files through a known good PHP file, and then use PHP error handling (http://php.net/set_error_handler) to determine if this error occurred, and then send a 403 header. Probably an Apache list would be better suited to knowing for sure any way around this... You could maybe tweak the PHP source to detect this condition and send 403 instead of trying to include() the file, which is what it seems to be doing. Yeah, thanks all. I usually have error logging off, but enabled it from time to time when hunting down bugs (and forget to add it back). Anyway, I guess I'll have to deal with just blank pages coming up in the event of a .php 403... not a big deal really, I just prefer constancy. I still don't really get why apache hands parsing off to php when it knows it doesn't have read access to the file, but I'll save that for another list!

[PHP] Security - chmod 777 - PHP upload/write
Hi, Sometimes when I write a PHP-script and upload it to a ISP through password protected FTP, the only way to write data to a folder is to run chmod 777 for that folder, I want to write (or save) a data to (e.g. file-upload, flat-file-database). However, if I do so, I have been told, everyone can write data to that file, which is a security risk. Is that true? If I do so, is it right that anyone can write a data to that folder? E.g.

It could be hacked to do it a number of ways, but it wouldn't be pretty and it wouldn't be very consistent either since we would have to only do it if no output has been sent on the request yet. So a sub-request or an auto-prepend would both change the behaviour.

You could also consider using http://php.net/date with the 'W' (ISO-8601
week number of year, weeks starting on Monday (added in PHP 4.1.0))
argument or 'z' (The day of the year (starting from 0)) and divide by 7.
You'd need to compute your offset to your 'first' week that you care
about, but...
?php
//PHP 4.1.0 and up:
$start_week = date('W', mktime(0, 0, 0, 9, 4, 2005));
echo This is week: , date('W', mktime(0, 0, 0, 10, 1, 2005)) -
$start_week, BR\n;

Depending on what you are doing and how you are already storing dates,
this could be cleaner.
Watch out, though, as you'll have issues on New Year's Eve if that's in
the middle of a 17-week period, as I suspect it is...
You could also just use:
?php
$start_week = mktime(0, 0, 0, 8, 2, 2005);
function seconds_to_week($seconds){
return $seconds / (60*60*24*7);
}
