run code in 300+ PHP versions simultaneously
<?php gc_enable(); class test { public $spl; public function __construct() { $this->spl = new SplPriorityQueue(); $this->spl->insert($this, 1); } } $i = 0; while($i < 100) { $test = new test(); unset($test); gc_collect_cycles(); echo sprintf('%1$04d: ', $i) . number_format(memory_get_usage()) .
