I was wondering how one would get the Text representation of a series of bytes in PHP? (Basically, the PHP version of C#'s Encoding.getString(string s) method.)

I've been scouring google, and I can find how to get a textstring-to-bytes, but not the other way around.

In PHP such a method:

Encoding.GetString Method (Byte[])

is not necessary because in PHP, strings are like Byte[]. And that's it. So there is no such method, however you can easily write it yourself:

function Encoding_GetString($stringOfBytes) {
    return (string) $byteString;
}

If you want to convert an array of integers in the range of 0-255 into a string, you can use chr, array_map and implode:

$string = implode(array_map('chr', $arrayOfByteIntegers));
