Have you ever wanted to know how much memory your PHP script uses when it runs? You might want this information if your script has a memory leak or takes a long time to execute. If that's the case then there's a great built-in function called memory_get_usage, which will display the exact amount of memory being used by your script. This function is really simple to use and will show you the amount of memory, in bytes, being allocated to the script.
Code: Select all
<?php
// Displays the amount of memory being used as soon as the script runs
echo memory_get_usage() . "\n";
/*
** Your code goes here
*/
// Displays the amount of memory being used by your code
echo memory_get_usage() . "\n";
?>
