note 89363 added to function.list

You can use isset with a list as it appears to unset the variable if there is not a value to assign to it. $values = array ( '1 2 3', '1 2', '1' ); foreach ($values as $v) { list ($v1, $v2, $v3) = explode (' ',$v); echo (isset ($v1) ? 'Y' : 'N'); echo (isset ($v2) ? 'Y' : 'N'); echo (isset ($v3) ? 'Y' : 'N'); echo '<br />'; } Results in: YYY YYN YNN YNN ---- Server IP: 208.69.120.35 Probable Submitter: 216.253.204.72 ---- Manual Page -- http://www.php.net/manual/en/function.list.php Edit -- https://master.php.net/note/edit/89363 Del: integrated -- https://master.php.net/note/delete/89363/integrated Del: useless -- https://master.php.net/note/delete/89363/useless Del: bad code -- https://master.php.net/note/delete/89363/bad+code Del: spam -- https://master.php.net/note/delete/89363/spam Del: non-english -- https://master.php.net/note/delete/89363/non-english Del: in docs -- https://master.php.net/note/delete/89363/in+docs Del: other reasons-- https://master.php.net/note/delete/89363 Reject -- https://master.php.net/note/reject/89363 Search -- https://master.php.net/manage/user-notes.php
