Solve PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried…

This error message can spring up in a previously functional PHP script when the memory requirements exceed the default 8MB limit. Don’t fret, though, because this is an easy problem to overcome.

To change the memory limit for one specific script by including a line such as this at the top of the script:

ini_set("memory_limit","12M");

The 12M sets the limit to 12 megabytes (12582912 bytes). If this doesn’t work, keep increasing the memory limit until your script fits or your server squeals for mercy.

You can also make this change permanently for all PHP scripts running on the server by adding a line like this to the server’s php.ini file:

memory_limit = 12M

Keep in mind that a huge memory limit is a poor substitute for good coding. A poorly written script may inefficiently squander memory which can cause severe problems for frequently executed scripts. However, some applications are run infrequently and require lots of memory like importing and processing a big data file.

Thanks for the tip, Rex!

Do you know of any tool to help analyse memory usage in PHP?

I consider this a temporary workaround for my situation... I need help to reduce memory usage.

Thanks, I couldn't remember what the setting was called to up the limit and this did the trick. Good advice on not setting it too high, don't want the server to run out of memory...

Joe

You should also verify that you aren't trying to include a file inside that file,

eg, the script name is somescript.php

and you have

include("somescript.php");

I've inadvertently done this when copying files.

I got the weirdest one the other day;

"Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 49 bytes) in /it/doesn't/matter/PdoDataSet.class.php on line 78"

49 is not greater than 8388608... I think there might be recursive include somewhere though. I am using the Recess! framework, so finding it is going to be a pain...
