        // Convert hex to string and vice versa.
//
// (Source: http://codedump.jonasjohn.de/)

function str_hex($string){
    $hex='';
    for ($i=0; $i < strlen($string); $i++){
        $hex .= dechex(ord($string[$i]));
    }
    return $hex;
}


function hex_str($hex){
    $string='';
    for ($i=0; $i < strlen($hex)-1; $i+=2){
        $string .= chr(hexdec($hex[$i].$hex[$i+1]));
    }
    return $string;
}

// example:

$hex = str_hex("test sentence...");
// $hex contains 746573742073656e74656e63652e2e2e

print hex_str($hex);
// outputs: test sentence...
