note 108311 added to function.class-uses

I made a slight mistake in my last note, the correct code is below. Since traits can use other traits, the following function will recursively check if a class uses a trait anywhere in the trait hierarchy. <?php function class_uses_recursive( $class, $trait ) { $traits = class_uses( $class ); while( !empty( $traits )) { foreach( $traits as $k => $t ) { if( $t == $trait ) return true; if( class_uses_recursive( $t, $trait )) return true; unset( $traits[ $k ] ); } } return false; } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 96.238.181.89 ---- Manual Page -- http://www.php.net/manual/en/function.class-uses.php Edit -- https://master.php.net/note/edit/108311 Del: integrated -- https://master.php.net/note/delete/108311/integrated Del: useless -- https://master.php.net/note/delete/108311/useless Del: bad code -- https://master.php.net/note/delete/108311/bad+code Del: spam -- https://master.php.net/note/delete/108311/spam Del: non-english -- https://master.php.net/note/delete/108311/non-english Del: in docs -- https://master.php.net/note/delete/108311/in+docs Del: other reasons-- https://master.php.net/note/delete/108311 Reject -- https://master.php.net/note/reject/108311 Search -- https://master.php.net/manage/user-notes.php
