php memory limit

[herbertjoei]

Hi,

I've been trying to search this forum for an answer but I can't seem to find one.

Question: How do i increase the PHP memory limit per domain? The script i am trying to install recommends at least 16MB and the server is currently at 8mb even though i changed the parameter in php.ini found in /usr/local/lib

Thanks in advance!

After you make the change make sure to restart Apache Service in WHM. This will make the changes take effect.

Hi,

I already did that and the application still reports 8M?? This is wierd, there's no memory limit variable in my PHPINFO.

If you do have zend installed, then the location of php.ini will be different. Do you have zend installed ?

Check your phpinfo() screen for the location of your correct PHP.INI file ...

It could be the one in /usr/local/lib but not necessarily and that goes
double important if you are using phpSuExec or SuPHP

Once you have edited the correct PHP.INI file then all you should need
to do is restart Apache to make the changes effective.

PS: Clear your web browser cache! One of the most common mistakes
when making system changes is to fail to clear your web cache which will
often make you think changes haven't been applied when in reality,
they have indeed been applied and working.

If you have Zend installed make sure you are editing /usr/local/Zend/etc/php.ini

Well, i checked my phpinfo and yes I cleared my cache . The path was correct at: /usr/local/lib/php.ini but still there was no memory_limit in the output. Is this normal?

Did you restart Apache?

Run

pico /usr/local/lib/php.ini

and look for memory_limit = 8M and change it to whatever you like. Then restart httpd.

hi,

Yep. I did restart apache and I did edit the php.ini and still the same. I verified this by checking php.ini after saving and restarted httpd via WHM and still missing memory_limit in phpinfo() and application still detects 8M.. wierd huh?

According to the PHP documentation, it must be enabled both at compile time, and in the php.ini file:

memory_limit integer
This sets the maximum amount of memory in bytes that a script is allowed to allocate. This helps prevent poorly written scripts for eating up all available memory on a server. In order to use this directive you must have enabled it at compile time. So, your configure line would have included: --enable-memory-limit. Note that you have to set it to -1 if you don't want any limit for your memory.

As of PHP 4.3.2, and when memory_limit is enabled, the PHP function memory_get_usage() is made available.

When an integer is used, the value is measured in bytes. You may also use shorthand notation as described in this FAQ.

Could it possible that his application is using a different php.ini file?

[cpanelkenneth]

Recent versions of PHP disabled the ability to have custom php.ini files in home directoreis (or anywhere else). Now, the location is defined at compile time.

That said, the PHP module could/would use a different php.ini than the CGI version, likewise if using the Zend extension.

Can you confirm....

If I dont compile memory_limit into PHP - changing the memory limit in php.ini will have no effect ?

I've never come across that before - usually its fine but we have a customer getting an out of memory (8MB) message and the server's php.ini is set to 32M
