Question: ```
assert.active = On

assert.bail = Off

```

How does it work?

Answer: 
If `assert.active=on` you can call `assert('$x==1')` in your code. If it fails (i.e. $x is something else than 1), depending on the value of assert.bail your script will either terminate or you get a warning. See more in <http://www.php.net/manual/en/function.assert.php>
From the [PHP Manual](http://www.php.net/manual/en/info.configuration.php#ini.assert.active):

> 
> assert.active: Enable assert()
>  evaluation.  
> 
>  assert.bail :
>  Terminate script execution on failed
>  assertions.
