Description:
------------
why in the world behaves a user function with a scalar type hint always like declare(strict_types=1)
has been set while builtin-functions have that behavior only when strict mode is really enabled
frankly that breaks a lot of code when you try to introduce scalar type hints to get rid of explicit
type casting randomly and defeats the whole purpuse of type hints in function definitions and that
is a MAJOR problem
Test script:
---------------
________________________________________________________
OK
[harry@srv-rhsoft:/downloads]$ cat test.php
<?php
$test = NULL;
echo trim($test);
?>
[harry@srv-rhsoft:/downloads]$ php test.php
[harry@srv-rhsoft:/downloads]$
[harry@srv-rhsoft:/downloads]$ cat test.php
<?php declare(strict_types=1);
$test = NULL;
echo trim($test);
?>
[harry@srv-rhsoft:/downloads]$ php test.php
Fatal error: Uncaught TypeError: trim() expects parameter 1 to be string, null given in
/mnt/data/downloads/test.php:3
Stack trace:
#0 /mnt/data/downloads/test.php(3): trim(NULL)
#1 {main}
thrown in /mnt/data/downloads/test.php on line 3
________________________________________________________
COMPLETLY BROKEN BEHAVIOR:
[harry@srv-rhsoft:/downloads]$ cat test.php
<?php
$test = NULL;
echo test($test);
function test(string $input)
{
}
?>
[harry@srv-rhsoft:/downloads]$ php test.php
Fatal error: Uncaught TypeError: Argument 1 passed to test() must be of the type string, null given,
called in /mnt/data/downloads/test.php on line 3 and defined in /mnt/data/downloads/test.php:5
Stack trace:
#0 /mnt/data/downloads/test.php(3): test(NULL)
#1 {main}
thrown in /mnt/data/downloads/test.php on line 5
