Memory available bigger than tried error in PHP-CodePudding

I am getting these errors repeatedly in my logs

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes)
PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 32768 bytes)

I don't get why it would die with memory size being much bigger then the bytes attempted to allocate!!

CodePudding user response：

You can expand your memory from within your file with the following line of code or directly in php.ini and restart server.

ini_set('memory_limit','16M');

change memory_limit in php.ini to higher value which I do not recommend at all - with your approach you will hit this wall once again. you can do following things.

Default php.ini memory_limit is 128 MB.
Optimize your code to use a normal amount of data
Optimize the query by selecting only used fields or use "pagination"

CodePudding user response：

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

overrides the default PHP memory limit.
