note 72144 added to language.operators.comparison

Since php 5.2 the operator == for object vs object is not recursion safe, it will cause a fatal error if one of the objects contains a refernce to it self (indirect refferences also counts here). If you are just checking if two object pointers points to the same object use === instead and aviod this issue (you might get a minimal speed bost too). ---- Server IP: 129.16.214.50 Probable Submitter: 213.66.131.204 ---- Manual Page -- http://www.php.net/manual/en/language.operators.comparison.php Edit -- https://master.php.net/note/edit/72144 Del: integrated -- https://master.php.net/note/delete/72144/integrated Del: useless -- https://master.php.net/note/delete/72144/useless Del: bad code -- https://master.php.net/note/delete/72144/bad+code Del: spam -- https://master.php.net/note/delete/72144/spam Del: non-english -- https://master.php.net/note/delete/72144/non-english Del: in docs -- https://master.php.net/note/delete/72144/in+docs Del: other reasons-- https://master.php.net/note/delete/72144 Reject -- https://master.php.net/note/reject/72144 Search -- https://master.php.net/manage/user-notes.php
