spl_object_hash



this is sufficient to guarantee that any two objects simultaneously coresiding in memory will have different hashes. uniqueness is not guaranteed between objects that did not reside in memory simultaneously, for example: var_dump(spl_object_hash(new stdclass()), spl_object_hash(new stdclass())); running this alone

there is a difference between being the same object, and having the same properties. $a = new stdclass("same", "parameters", ); $b = new stdclass("same", "parameters", ); var_dump($a == $b); true var_dump($a === $b); false! $b = $a; var_dump($a === $b); now true. i tried using "spl_object_hash()" ( php.net/manual/en/function.splobjecthash.php) but this function returns another value each time i reload the page. for testing, this objects is steady and stays the same and completely unchanged. never the less "spl_object_hash()" returns different results time and

github is where people build software. more than million people use github to discover, fork, and contribute to over million projects. unitofwork uses an array documentidentifiers to store document id's indexed by the result of function spl_object_hash . there is another array documentstates , also indexed by the same values. however the spl_object_hash values are not completely unique: once an object is not referenced anywhere

bonsoir, j'ai un probléme lors de la persistance de mon objet: code : sélectionner tout visualiser dans une fenêtre à part warning: spl_object_hash & description. string spl_object_hash ( object $obj ). cette fonction retourne un identifiant unique pour l'objet. cet identifiant peut être utilisé comme clé de hashage pour stocker les objets ou pour les identifier.

to add to markus dot albe at inator dot com comment. the unique identifiers of destroyed objects can and will be reused. <?php class foo{ private static $test = ; public function __construct(){ self::$test; } } $foo = new foo(); $foo = new foo(); $foo = new foo(); new unique identifier echo spl_object_hash($foo).
