note 129676 added to function.array-combine

As of PHP 8.0, array_combine throws ValueError if the number of elements for each array is not equal; To be on a safer side, you can perform a check instead. $arrayk = array( 'key1', 'key2', 'key3' ); $arrayv = array( 'v1', 'v2', 'v3' ); if ( count( $arrayk ) === count( $arrayv ) ) { echo '<pre>'; var_dump( array_combine( $arrayk, $arrayv ) ); echo '</pre>'; } else { return false; } ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 129.205.124.194) ---- Manual Page -- https://php.net/manual/en/function.array-combine.php Edit -- https://main.php.net/note/edit/129676 Del: integrated -- https://main.php.net/note/delete/129676/integrated Del: useless -- https://main.php.net/note/delete/129676/useless Del: bad code -- https://main.php.net/note/delete/129676/bad+code Del: spam -- https://main.php.net/note/delete/129676/spam Del: non-english -- https://main.php.net/note/delete/129676/non-english Del: in docs -- https://main.php.net/note/delete/129676/in+docs Del: other reasons-- https://main.php.net/note/delete/129676 Reject -- https://main.php.net/note/reject/129676 Search -- https://main.php.net/manage/user-notes.php
