In other words, wrong type arguments get converted (coerced) to the expected type.

If you run the script, it will output the sum of the args converted to integer values. The sumints.php script is listed below, including a commented-out declare directive that we will discuss later when we cover strict scalar types Invoke the function with some of the arguments supplied as floating-point numbers and others as string, for example: Create a script sumints.php and define a vararg function taking parameters of type int. Scalar types come in two kinds, coercive (default) and strict. Argument 1 passed to f() must be an instance of A, instance of C given Assuming the same setup as in the first article PHP 7 - Getting Started and OOP Improvements, run the script with url While calling f() passing instances of classes A and B does not generate an error and outputs the value defined in function, calling f() with an argument of type C generates a TypeError: Then, the script invokes function passing instances of class A, B and C successively as arguments. Class C does not extend any class and defines a function f() with a parameter of type A. To demonstrate type declarations with an example, create a script ( typedeclr.php) in the document root directory and copy the following listing to the script: Ĭlass B extends class A.
