note 69588 deleted from function.array-search by crell

Note Submitter: mark dot php at mhudson dot net ---- 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()
