note 130422 added to function.gc-collect-cycles

<?php gc_collect_cycles(); ?> triggers PHP's garbage collector to explicitly search for and clean up circular references - objects that reference each other but are no longer accessible by the program. Although PHP's garbage collector runs automatically, in long-running scripts or memory-intensive operations (such as daemons, CLI tools, or large loops), calling this function manually can help reduce memory usage and prevent memory leaks. Example: <?php class Node { public $ref; } $a = new Node(); $b = new Node(); $a->ref = $b; $b->ref = $a; unset($a, $b); // At this point, $a and $b are no longer accessible, but the circular reference remains in memory. // Force cleanup: $collected = gc_collect_cycles(); echo "Collected cycles: $collected\n"; ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 109.72.53.236) ---- Manual Page -- https://php.net/manual/en/function.gc-collect-cycles.php Edit -- https://main.php.net/note/edit/130422 Del: integrated -- https://main.php.net/note/delete/130422/integrated Del: useless -- https://main.php.net/note/delete/130422/useless Del: bad code -- https://main.php.net/note/delete/130422/bad+code Del: spam -- https://main.php.net/note/delete/130422/spam Del: non-english -- https://main.php.net/note/delete/130422/non-english Del: in docs -- https://main.php.net/note/delete/130422/in+docs Del: other reasons-- https://main.php.net/note/delete/130422 Reject -- https://main.php.net/note/reject/130422 Search -- https://main.php.net/manage/user-notes.php
