PHP: ‘Fatal error: Allowed memory size of 8388608 bytes exhausted’

Reason why you see this message is due to PHP memory leakage. PHP is trying to load a large image or file into memory and is not finding enough space for it to load.

If you think, that you will need the necessary feature to upload large files then there are two ways by which you can enable this feature.

i) Edit the physical file and have the line
ini_set(“memory_limit”,”20M”);

ii) Edit php.ini and add the following line. You need to restart the apache/IIS server once php.ini file is modified.
memory_limit=32M

PHP: Fatal error: Maximum execution time of 30 seconds exceeded

kurinchilamp — Fri, 29 May 2009 01:58:12 +0000

This error happens when the execution time of the PHP script exceeds the time limit for program execution in Php.ini file.

By default the timer is set to 30 seconds in php.ini and you can track the time limit by tracing for ‘max_execution_time’ directive in php.ini.

A quick way to find the execution time set for PHP is to check the phpinfo() function.

Solution:
You can set the time limit by issuing “set_time_limit(60);” statement to increase the time limit.

A better way would be trace where the bottlenecks are in the program to identify what causes the time lag. Possible causes may be

* Poorly structured queries
* Never ending iterations
* Read lock on files when they are opened by multiple sources etc.
