note 94679 added to function.array-intersect-key

Regarding my previous note, you could also use reset() or current() in place of implode(). <?php $b = implode('', array_intersect_key(someFuncReturningAnArray(), array('a'=>''))); echo print_r($b, 1) . "\n----------\n"; $b = reset(array_intersect_key(someFuncReturningAnArray(), array('a'=>''))); echo print_r($b, 1) . "\n----------\n"; $b = current(array_intersect_key(someFuncReturningAnArray(), array('a'=>''))); echo print_r($b, 1) . "\n----------\n"; ?> All return the identical result ---- Server IP: 69.147.83.197 Probable Submitter: 71.248.188.31 ---- Manual Page -- http://www.php.net/manual/en/function.array-intersect-key.php Edit -- https://master.php.net/note/edit/94679 Del: integrated -- https://master.php.net/note/delete/94679/integrated Del: useless -- https://master.php.net/note/delete/94679/useless Del: bad code -- https://master.php.net/note/delete/94679/bad+code Del: spam -- https://master.php.net/note/delete/94679/spam Del: non-english -- https://master.php.net/note/delete/94679/non-english Del: in docs -- https://master.php.net/note/delete/94679/in+docs Del: other reasons-- https://master.php.net/note/delete/94679 Reject -- https://master.php.net/note/reject/94679 Search -- https://master.php.net/manage/user-notes.php
