Basic usage
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
以上例程的输出类似于：
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
