PHP Fatal error allowed memory size exhausted

Question

I\'m writing a codeigniter application, upon doing a query i get hit with the following fatal error.

Fatal error: Allowed memory size of 134217728 byt

Answer 1

If anybody else has this problem:

Make sure your memory size in php.ini has an M after the number.

I had 512 in there....when I changed it to 512M .....no more problem.

Answer 2

Your code looks fine. Check if some function is getting called repeatedly.

You could use

ini_set('memory_limit', '-1');

as a temporary solution. or just increase the memory_limit

Chceck you php.ini file. If it is in the below form,

memory_limit=8G

Change that in the form of MB

memory_limit=8192M

You can also do it in your code like

ini_set('memory_limit', '8192M'); 

Answer 3

The problem occurs because a private method kept calling itself over and over again until the allocated memory is exhausted and the script stops execution

private function get_member_data($tid){
    return $this->get_member_data($tid);
}

This is a stupid human error, the above method should have been re-written as below

private function get_member_data($tid){
//Call to model method
    return $this->invest->get_member_data($tid);
}

Sorry, and thanks everyone.

Answer 4

If you want to know where the memory goes you should look into PHP memory profiling: PHP memory profiling

Personally I would just increase the PHP max_memory to 256MB and see if it's enough ;)

Answer 5

Put this line on your codeigniter's index.php. So it will be affected for whole project.

ini_set('memory_limit', '-1');

Note: This is just a quick fix. This bug has not been resolved in php itself.
