Basic example on using memtrack extension:
Example #1 Creating large array in a
function
<?php
/* /tmp/example1.php */
function foo() {
$a = array();
for ($i = 0; $i < 10000; $i++) $a[] = "test";
return $a;
}
$arr = foo();
?>Run the example with the following command:
php -d memtrack.enabled=1 -d memtrack.soft_limit=1M -d memtrack.vm_limit=3M /tmp/example1.php
The above example will output something similar
to:
Warning: [memtrack] [pid 26177] user function foo() executed in /tmp/example1.php on line 10 allocated 4194304 bytes in /tmp/example1.php on line 0 Warning: [memtrack] [pid 26177] virtual memory usage on shutdown: 32911360 bytes in Unknown on line 0
