    Esempi

    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)
}
