note 119284 added to control-structures.foreach

Note: Empty arrays are handled just fine by foreach, but for fail-safe code, you should always check that what is passed in fact is an array, like this: <?php if( is_array( $a) ) { foreach( $a as $v) { ... } } else // $a is not an array ; ---- Server IP: 93.124.244.58 Probable Submitter: 84.214.189.69 ---- Manual Page -- http://php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/119284 Del: integrated -- https://master.php.net/note/delete/119284/integrated Del: useless -- https://master.php.net/note/delete/119284/useless Del: bad code -- https://master.php.net/note/delete/119284/bad+code Del: spam -- https://master.php.net/note/delete/119284/spam Del: non-english -- https://master.php.net/note/delete/119284/non-english Del: in docs -- https://master.php.net/note/delete/119284/in+docs Del: other reasons-- https://master.php.net/note/delete/119284 Reject -- https://master.php.net/note/reject/119284 Search -- https://master.php.net/manage/user-notes.php
