   memory_get_usage -- Returns the amount of memory allocated to PHP

Description

   int memory_get_usage ( void )

   Returns the amount of memory, in bytes, that's currently being
   allocated to your PHP script.

   memory_get_usage() will only be defined if your PHP is compiled with
   the --enable-memory-limit configuration option.

   Example 1. A memory_get_usage() example
   <?php
   // This is only an example, the numbers below will
   // differ depending on your system
   echo memory_get_usage() . "\n"; // 36640
   $a = str_repeat("Hello", 4242);
   echo memory_get_usage() . "\n"; // 57960
   unset($a);
   echo memory_get_usage() . "\n"; // 36744
   ?>
