PHP中的asciiEncoding.GetString（）？

This is written in C#

ASCIIEncoding asciiEncoding = new ASCIIEncoding();
byte[] something= new byte[checked (buffer.Length - 1 + 1)];
str = asciiEncoding.GetString(something);

I am trying to find a function in PHP that does the same thing as asciiEncoding.GetString()

Is there any?

asciiEncoding.GetString will decode a byte array into a string. In PHP it could look like this:

$byteArray = unpack('C*', 'Some string');
$str = implode(array_map('chr', $byteArray));
