How to Check & increase memory limit

Posted by Wai_Wai on September 24, 2005 at 6:13pm

Hi.
1) How to check if there's any upper limit of memory in my web hosting? If s, how much?
2) What is the best way to increase my memory limit?
There're 3 ways:
- php.ini
- index.php
- settings.php

Which one should I edit?
What're the pros and cons?
What code do I need to add (for each file separately)?

Thanks!

Admin - module not loading in Drupal - Memory Limit

Posted by london3 on September 26, 2005 at 1:54pm

If you run out of PHP memory. You'll need to either uninstall some modules or increase the memory_limit variable in php.ini.

/etc/php4/apache2/php.ini
; change from 8MB to 16MB
memory_limit = 16M ; Maximum amount of memory a script may consume (8MB)

I can't even find etc in my main folder, and in public_html folder.
Out of luck :(
Probably my web hoster hid it.

settings.php

Add this to your settings.php:

ini_set('memory_limit', '100M');

It worked for me on a server that I have no control over. I had to set the limit so high in order to get some image conversions to work...

Would you mind doing me a favour?

Posted by Wai_Wai on September 26, 2005 at 8:54pm

Hey.
It seems the above doesn't work.
I don't know what's wrong.
What web hoster are you using?

After all, would you mind trying to do the following:

1) Create an info.php

<?php 
phpinfo(); 
?>

2) Upload it to anywhere in your website.
Then access it.

3) A page will load up showing you a lot ofinformation about PHP.
Look for the following info:
........................Configuration

..........................PHP Core

Directive.........Local Value......Master Value
.....
memory_limit....?M................?M (<-- Look for these values!)

Tell me what're the value of the above in your case.
Thanks a lot.

It worked for me on a server running Linux with Apache 1 and PHP 4. My phpinfo says the memory limit is 8M in both cases which it really isn't, though, because my webapp crashed hard before I set the limit higher.

It seems the phpinfo is not

It seems the phpinfo is not reliable. :P
So I think the settings will work on my server too.

No memory_limit shown in phpinfo()

Posted by ZenCoder on October 27, 2007 at 3:54am

I am trying to find out what my memory_limit is, but phpinfo() simply doesn't report the value.

I searched for "memory" and then just "mem"

Shared Host
Apache 1.3.37
PHP 4.4.4
Zend Memory Manager enabled
Server API CGI

Can someone explain why the value isn't there?

Same

I've placed php.ini files in numerous locations, and I also tried the ini memory directive in .htaccess.

No memory limit is shown in phpinfo() in the root Drupal directory.

No limit show because there is no limit

Posted by ZenCoder on November 7, 2007 at 4:18am

My host has php running via CGI rather than as an apache module (I know this isn't a good setting for drupal or any other app that does lots of small bits of php & sql). There is no memory limit set. Well I am sure there is a limit but its handled by the OS and not php.

php.ini

Posted by kbahey on September 26, 2005 at 2:16pm

php.ini is the best way.

However, this will work only if your hosting company allows such setting in such file.

I am allowed to create php.ini
But how can I know if the settings work?

How to check? Use the venerable phpinfo function and look for the settings or ask your host provider.

Hi.
Here's what I once tried to add memory_limit code in:
- php.ini
- settings.php

Then I tried to verify the change by uploading 7 running this *.php:

<?php 
phpinfo(); 
?>

the following info shows:
........................Configuration

..........................PHP Core

Directive.........Local Value......Master Value
memory_limit....8M................8M

Why no change is made?
Does it mean that the memory_limit setting fails?
Is the result reliable to tell no change occurs?

Thanks.

if you have changed a setting in php.ini you would need to restart the apache service for the change to take effect
