But, if you use default values in arguments in methods, fatal error is not follow: <?php interface myInterface { public function __construct(); } class concret implements myInterface { public function __construct($arg=null) { print_r(func_get_args()); } } $obj = new concret(123); ?> Array ( [0] => 123 ) ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/language.oop5.interfaces.php Edit -- https://master.php.net/note/edit/114320 Del: integrated -- https://master.php.net/note/delete/114320/integrated Del: useless -- https://master.php.net/note/delete/114320/useless Del: bad code -- https://master.php.net/note/delete/114320/bad+code Del: spam -- https://master.php.net/note/delete/114320/spam Del: non-english -- https://master.php.net/note/delete/114320/non-english Del: in docs -- https://master.php.net/note/delete/114320/in+docs Del: other reasons-- https://master.php.net/note/delete/114320 Reject -- https://master.php.net/note/reject/114320 Search -- https://master.php.net/manage/user-notes.php
