Same as RoundFunctionReturnTypeExtension.

Since the situation where the ini include_path entry does not exist is an abnormal situation, it seems that __benevolent<> can be added.

These functions return only positive values.

This function returns false only when it receives a value outside the integer range.
PHP Manual says:
mktime()returns the Unix timestamp of the arguments given, or false if the timestamp doesn't fit in a PHP integer.
It seems that even if PHP_INT_MAX is passed for all parameters, this value will never be exceeded.

This extension change is unnecessary, but it removes the duplicate definition of the type with functionMap.

Thank you, changes make sense 😊 |

Add
__benevolent<>to functions whose documentation says "return false", which return false when passed a parameter of the wrong type, or which do not return false upon normal use.Modify the functionMap for other functions, including those already covered by DynamicFunctionReturnTypeExtension.
