.. function:: compareStrings()


    Compare two strings to avoid timing attacks
    
    C function memcmp() internally used by PHP, exits as soon as a difference
    is found in the two buffers. That makes possible of leaking
    timing information useful to an attacker attempting to iteratively guess
    the unknown string (e.g. password).
