Example #1 gc_status() Usage
<?php
// create object tree that needs gc collection
$a = new stdClass();
$a->b = [];
for ($i = 0; $i < 100000; $i++) {
$b = new stdClass();
$b->a = $a;
$a->b[] = $b;
}
unset($a);
unset($b);
gc_collect_cycles();
var_dump(gc_status());
Il precedente esempio visualizzerà qualcosa simile a:
array(4) { ["runs"]=> int(5) ["collected"]=> int(100002) ["threshold"]=> int(50001) ["roots"]=> int(0) }
Output of the above example in PHP 8.3 is similar to:
array(12) { ["running"]=> bool(false) ["protected"]=> bool(false) ["full"]=> bool(false) ["runs"]=> int(5) ["collected"]=> int(100002) ["threshold"]=> int(50001) ["buffer_size"]=> int(131072) ["roots"]=> int(0) ["application_time"]=> float(0.031182458) ["collector_time"]=> float(0.020106291) ["destructor_time"]=> float(0) ["free_time"]=> float(0.003707167) }
