function hex2bin($str) {
$bin = "";
$i = 0;
do {
$bin .= chr(hexdec($str{$i}.$str{($i + 1)}));
$i += 2;
} while ($i < strlen($str));

}
Xampp is telling me theres something wrong on the last line (174) which would be the }, but there isn't a problem with it at all

You don't index into arrays with curly braces "{}" to index arrays in PHP, you use square ones [].
i.e:
Should actually be
However this code isn't going to do what the function name implies (convert a hexadecimal string into a binary string).
i.e:
Code:
$bin .= chr(hexdec($str{$i}.$str{($i + 1)}));
Code:
$bin .= chr(hexdec($str[$i].$str[$i + 1]));
