substr($myStr, -4, 4);

or generically: substr(string, pos, number);

This function returns [number] characters from [string], starting at position [pos]. If [pos] < 0, it starts that many characters from the end, e.g. -4 means start 4 characters from the end of [string].

It may be a little more efficient to use in this case :

substr($myStr, 3);

Particulary if used in big loops
