Edit Question
Title
Body
In PHP, if you have a variable with binary data, how do you get specific bytes from the data? For example, if I have some data that is 30 bytes long how do I get the first 8 bytes? Right now, I'm treating it like a string, using the substr() function: $data = //... $first8Bytes = substr($data, 0, 8); Is it safe to use substr with binary data? Or are there other functions that I should be using?
