Subject: [PATCH 1/2] Changed startsWith and endsWith to use substr (non
 mbstring), this is ok here because it doesn't matter whether it's multi-byte
 unicode chars or not, just that the same number of bytes match at the start
 or the end.

The performance of the existing methods becomes increasingly slow with larger strings due to
 mbstring functions.
