note 108311 deleted from function.class-uses by danbrown

Note Submitter: josh at bitmagnet dot org ---- 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; } ?>
