note 10286 added to bin2hex

This is useful if you want to give parameters to your script via links (and not forms). Then you need to change some chars into their hex-numbers. E.g. space to %20. function asc2form ($input) { $nochange = array ("a","b","c","d","e","f","g", "h","i","j","k","l","m","n", "o","p","q","r","s","t","u","v","w","x","y","z", "A","B","C","D","E","F","G","H","I","J","K","L","M","N", "O","P","Q","R","S","T","U","V","W","X","Y","Z", "0","1","2","3","4","5","6","7","8","9","_","-"); for ($i=0;$i<strlen($input);$i++) { $char = substr($input,$i,1); if (in_array($char,$nochange)) { $ret .= $char; } else { $ret .= "%".bin2hex($char); } return $ret; } http://www.php.net/manual/function.bin2hex.php
