NOTE!! When using "file()" to load the contents of a file into an array, newlines ("\n") and carriage returns ("\r") are left on each line of the array. These characters cause functions like array_search() to appear to fail as the line endings are somewhat hidden. Use something like this to do a cleanup before using array_search() or in_array(): $array = str_replace (array("\r", "\n"), '', file ($file)); --was-- NOTE!! When using "file" to load the contents of a file into an array newlines "\n" are inclued on each line of the array. The newlines cause functions like array_search to appear to fail as the newline is somewhat hidden. Use something like this to do a cleanup before using array_search or in_array: foreach (file ('test.txt') as $line) { $array[] = substr ($line, 0, -1); } http://www.php.net/manual/en/function.array-search.php
