PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

     * Cast to an integer if we can, safely.
     * 
     * If you pass it a float in the range (~PHP_INT_MAX, PHP_INT_MAX)
     * (non-inclusive), it will sanely cast it to an int. If you it's equal to
     * ~PHP_INT_MAX or PHP_INT_MAX, we let it fail as not an integer. Floats 
     * lose precision, so the <= and => operators might accidentally let a float
     * through.

     * @param numeric $number The number we want to convert to an int
     * @param boolean $fail_open Set to true to not throw an exception

There is no parameter named $fail_open. Was it maybe removed?

     * @return int (or float if $fail_open)
