note 95666 added to function.spl-object-hash

To add to markus dot albe at mailinator dot com comment. The unique identifiers of destroyed objects can and will be reused. <?php class Foo{ private static $test = 0; public function __construct(){ self::$test++; } } $foo1 = new Foo(); $foo2 = new Foo(); $foo3 = new Foo(); //new unique identifier echo spl_object_hash($foo1)."<br />\n"; //new unique identifier echo spl_object_hash($foo2)."<br />\n"; //new unique identifier echo spl_object_hash($foo3)."<br />\n"; $foo1 = new Foo(); //new unique identifier because, when we created Foo, foo1 still existed echo spl_object_hash($foo1)."<br />\n"; $foo1 = new Foo(); //same identifier as the first $foo1 because it was destroyed, //thus released the identifier echo spl_object_hash($foo1)."<br />\n"; ?> This will output something like: 000000007ec3fcb5000000003f984510 000000007ec3fcb6000000003f984510 000000007ec3fcb7000000003f984510 000000007ec3fcb0000000003f984510 000000007ec3fcb5000000003f984510 ---- Server IP: 69.147.83.197 Probable Submitter: 213.93.229.126 ---- Manual Page -- http://www.php.net/manual/en/function.spl-object-hash.php Edit -- https://master.php.net/note/edit/95666 Del: integrated -- https://master.php.net/note/delete/95666/integrated Del: useless -- https://master.php.net/note/delete/95666/useless Del: bad code -- https://master.php.net/note/delete/95666/bad+code Del: spam -- https://master.php.net/note/delete/95666/spam Del: non-english -- https://master.php.net/note/delete/95666/non-english Del: in docs -- https://master.php.net/note/delete/95666/in+docs Del: other reasons-- https://master.php.net/note/delete/95666 Reject -- https://master.php.net/note/reject/95666 Search -- https://master.php.net/manage/user-notes.php
