Should I use type hinting in PHP?

With Type hinting we can specify the expected data type (arrays, objects, interface, etc.) for an argument in a function declaration. This practice can be most advantageous because it results in better code organization and improved error messages.

What is type hinting in PHP with example?

In simple word, type hinting means providing hints to function to only accept the given data type. In technical word we can say that Type Hinting is method by which we can force function to accept the desired data type. In PHP, we can use type hinting for Object, Array and callable data type.

Which data types can be declared with type hinting?

In PHP 5, you can use array , callable , and class for type hints. In PHP 7+, you can also use scalar types such as bool , float , int , and string . In this case, PHP implicitly coerces 2.5 into an integer ( 2 ) before calculating the sum. Therefore, the result is an integer.

Should I use type hints Python?

Type hints work best in modern Pythons. Annotations were introduced in Python 3.0, and it’s possible to use type comments in Python 2.7. Still, improvements like variable annotations and postponed evaluation of type hints mean that you’ll have a better experience doing type checks using Python 3.6 or even Python 3.7.
