The statement is returned true regardless of the condition

Question

For example, if I have

assert('2<1');

It turns out that the statement returns as true. I also copy example # 2 from http://php.net/manual/en/function.assert.php , and he also rated each statement as true when this is clearly not the case. Any idea what could be causing this?

Edit -

<?php
    var_dump(assert('2<1'));
?>

Output

true

If I ran this at http://sandbox.onlinephpfunctions.com/ , the statement will not complete as expected. However, this does not happen on my test server.

Edit # 2 - PHP Version:
