[RFC] Weak maps - In PHP 7.4, support for weak links was added through a special WeakReference class. But in reality, applications need a WeakMap collection that cannot be implemented based on WeakReference. Actually, it is proposed to add it.

Hidden text

$map = new WeakMap(); $obj = new stdClass(); $map[$obj] = 42; var_dump($map); // object(WeakMap)#1 (1) { // [0]=> // ["key"] => object(stdClass)#2 (0) {} // ["value"] => int(42) // } // } //   , //      WeakMap unset($obj); var_dump($map); // object(WeakMap)#1 (0) { // }
