Chaque type pris en charge par PHP, à l'exception du type resource, peut être utilisé dans une déclaration de type par l'utilisateur. Cette page contient un journal des modifications de la disponibilité des différents types et de la documentation sur leur utilisation dans les déclarations de type.

Type declarations can be added to function arguments, return values, as of PHP 7.4.0, class properties, and as of PHP 8.3.0, class constants. They ensure that the value is of the specified type at call time, otherwise a TypeError is thrown.

PHP’s types are categorized as scalar types and composite types. The scalar types are Boolean, integer, floating point, string, and null. The composite types are array , and object. The resource is an opaque type whose internal structure is not specified and depends on the implementation. The scalar types are value types.

With PHP 7 we now have added Scalar types. Specifically: int, float, string, and bool. By adding scalar type hints and enabling strict requirements, it is hoped that more correct and self-documenting PHP programs can be written. It also gives you more control over your code and can make the code easier to read.
