Php memory usage code-PHP source code

Ec (2); helps code optimization by detecting memory usage of scripts. PHP provides a garbage collector and a very complex memory manager. The amount of memory used for script execution is increased or decreased. To get the current memory usage, we can use the memory_get_usage () function. To obtain the maximum memory usage at any time point, you can use the memory_limit () function. Viewsourceprint? 01 echo & quot; I script ec (2); script
