Given code
<?php
function a(boolean $value){
var_dump($value);
}
a(true);
I receive error
TypeError: Argument 1 passed to a() must be an instance of boolean, boolean given
What is going on here?
Only valid typehint for boolean
is bool
. As per documentation boolean
isn't recognized as alias of bool
in typehints. Instead it is treated as class name.
Same goes for int
(scalar) and integer
(class name), which will result in error
TypeError: Argument 1 passed to a() must be an instance of integer, integer given
In this specific case object of class boolean
is expected but true
(bool, scalar) is passed.
Valid code is
<?php
function a(bool $value){
var_dump($value);
}
a(true);
which result is
bool(true)
