Description:
------------
Hi, when you want to set an hard pypage in a function to test if you have a string/integer/float

The result of var_dump will be float(123) and not a typage error !!!

Test script:
---------------
function test (float $element)
{
    var_dump($element);
}

test('123');
die;

Expected result:
----------------
Catchable fatal error: Argument 1 passed to test() must be an instance of float, instance of string given

Actual result:
--------------
float(123)

This is what strict-types are for - see https://3v4l.org/nUKlM and https://wiki.php.net/rfc/scalar_type_hints_v5

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

As sjon at hortensius dot net stated, this is expected behavior for coercive type enforcement.  To enable strict type enforcement, include `declare(strict_types=1);` at the top if your *calling* script.  Note that strict enforcement is performed at the callsite and is set on a per-file basis.
