Note Submitter: slicky at newshelix dot com ---- Be aware that this function could result into unwanted results if you check single chars in an array. For instance: You have a simple string and want to repeat this string evertime it ends. <?php for ($i=0; $i < strlen($string);$i++){ if(!is_string($key[$x])) $x = 0; echo $key[$x]; $x++; } ?> This will print you out the key, but won't iterate it since $x won't be reset. is_string function will give out true at element in that string, even if it doesn't exist. for instance is_string $key[1000] while your string is just 10chars long. However this doesn't matter just use $key[$x] == '' instead. Of course you won't use this to iterate a string, but you might come across something where this get useful, for instance for a en/decrypt engine.
