I was going to complain bitterly about array_search() using zero-based indexes, but then I realized I should be using in_array() instead. // if ( isset( $_GET['table'] ) and array_search( $_GET['table'], $valid_tables) ) { // BAD: fails on first[0] element // if ( isset( $_GET['table'] ) and ( FALSE !== array_search( $_GET['table'], $valid_tables) ) ) { OK: but wasteful and convoluted if ( isset( $_GET['table'] ) and in_array( $_GET['table'], $valid_tables) ) { // BETTER The essence is this: if you really want to know the location of an element in an array, then use array_search, else if you only want to know whether that element exists, then use in_array() ---- Server IP: 64.71.164.2 Probable Submitter: 65.88.178.10 ---- Manual Page -- http://www.php.net/manual/en/function.array-search.php Edit -- https://master.php.net/note/edit/69588 Del: integrated -- https://master.php.net/note/delete/69588/integrated Del: useless -- https://master.php.net/note/delete/69588/useless Del: bad code -- https://master.php.net/note/delete/69588/bad+code Del: spam -- https://master.php.net/note/delete/69588/spam Del: non-english -- https://master.php.net/note/delete/69588/non-english Del: in docs -- https://master.php.net/note/delete/69588/in+docs Del: other reasons-- https://master.php.net/note/delete/69588 Reject -- https://master.php.net/note/reject/69588 Search -- https://master.php.net/manage/user-notes.php
