PHP Memory usage Information code

It is advantageous to code optimization by detecting memory usage of scripts. PHP provides a garbage collector and a very complex memory manager. The amount of memory that the script uses when it executes, with a rise or fall. In order to get the current memory usage, we can use the Memory_get_usage () function. You can use the Memory_limit () function if you need to obtain the highest amount of memory usage at any point in time. View sourceprint?01 echo "Initial:
