Shifting integers by values greater than or equal to the system long
integer width results in undefined behavior. In other words, don't shift
more than 31 bits on a 32-bit system, and don't shift more than 63 bits on
a 64-bit system.
Prior to PHP 7.0, shifting integers by values greater than or equal to the
system long integer width, or by negative numbers, results in undefined
behavior. In other words, if you're using PHP 5.x, don't shift more than 31
bits on a 32-bit system, and don't shift more than 63 bits on 64-bit
system.
