PHP: Converting integer to int - getting error

I understood there wasn't much, if any different between int and integer in PHP. I must be wrong.

I'm passing a integer value to a function which has int only on this value. Like so:-

$new->setPersonId((int)$newPersonId); // Have tried casting with (int) and intval and both

The other side I have:-

    public function setPersonId(int $value) {
        // foobar
    }

Now, when I run - I get the message:-

"PHP Catchable fatal error: Argument 1 passed to setPersonId() must be an instance of int, integer given"

I have tried casting in the call with (int) and intval().

Any ideas?

Make sure that PersonID property is defined as int not integer:

private int $personId;

instead of

private integer $personId;

To explicitly convert a value to integer, use either the (int) or (integer) casts. However, in most cases the cast is not needed, since a value will be automatically converted if an operator, function or control structure requires an integer argument. A value can also be converted to integer with the intval() function.

Type hinting in PHP only works for objects and not scalars, so PHP is expecting you be passing an object of type "int".

You can use the following as a workaround

public function setPersonId($value) {
    if (!is_int($value)) {
        // Handle error
    }
}
