Well, the problem is in the return if, you are using = as comparison operator, where instead you should have used ==, and so the function will return always true... also you should use a static function from the moment that you don't need a object to invoke this function, try with this one:
<?php
class formvalidation {
public static function check_empty_input($inputs = []) : bool {
$everything_filled = true; //start with this supposition
foreach ($inputs as $valor) {
if (empty($valor)) {
$everything_filled = false; // is something is empty, than the supposition is false
break;
}
}
return $everything_filled; // return the supposition result value
}
}
$is_my_inputs_filled = formvalidation::check_empty_inputs([
$_POST['name'],
$_POST['email'],
$_POST['pass'],
$_POST['confirmpass'],
]);
If it doesn't work, please explain better what you mean with "doesn't work"
