memory_get_usage(true) vs Yii Debugger

Question

I am use Yii2. Who can help? memory_get_usage(true) returns 8-9MB but in Yii Debbuger Memory:58.3MB. How can I fix it?

Answer 1

As shown in this file Yii2-debug tool is using memory_get_peak_usage() function and that is not the same as memory_get_usage() function. according to their respective documentations :

memory_get_peak_usage — Returns the peak of memory allocated by PHP memory_get_usage — Returns the amount of memory allocated to PHP

So the Yii-debugger tool is doing it right by returning the amount of memory being used instead of the amount allocated to php.
