note 102204 added to language.oop5.object-comparison

Interestingly enough due to the operator precidences changing the values of identical objects may not be as obvious as expected. <?php class A { private $val; public function set($val) { $this->val = $val; return $this; } } $a = new A; $b = new A; $c = $a; echo var_dump($a->set('foo') == $b->set('bar')); // Will evaluate as boolean false echo var_dump($a->set('foo') == $c->set('bar')); // Will evaluate a boolean true ?> ---- Server IP: 69.147.83.197 Probable Submitter: 82.18.86.179 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.object-comparison.php Edit -- https://master.php.net/note/edit/102204 Del: integrated -- https://master.php.net/note/delete/102204/integrated Del: useless -- https://master.php.net/note/delete/102204/useless Del: bad code -- https://master.php.net/note/delete/102204/bad+code Del: spam -- https://master.php.net/note/delete/102204/spam Del: non-english -- https://master.php.net/note/delete/102204/non-english Del: in docs -- https://master.php.net/note/delete/102204/in+docs Del: other reasons-- https://master.php.net/note/delete/102204 Reject -- https://master.php.net/note/reject/102204 Search -- https://master.php.net/manage/user-notes.php
