Is there a way to convert a string to binary then back again in the standard PHP library?
To clarify what I'm trying to do is store a password on a database. I'm going to convert it first using a hash function then eventually store it as binary.
I've found the best way is to use this function. Seems to hash and output in binary at the same time.
You want to use pack
and base_convert
.
// Convert a string into binary
// Should output: 0101001101110100011000010110001101101011
$value = unpack('H*', "Stack");
echo base_convert($value[1], 16, 2);
// Convert binary into a string
// Should output: Stack
echo pack('H*', base_convert('0101001101110100011000010110001101101011', 2, 16));
