some may move to the dark side and say “get away you f***ing spammer”, but I just wanted to know why all the files from CI do not include the final and beloved ?>

I may say “because compilation” but that’s not a certain answer… And will add that: once, when I was writing my first controller, I finished the class with the glorious braces and just a line after added the “?>”... so final result would’ve like this
```
}
?>
```
... I stood in black when an error pulled out… After 14 Hours I added an enter between braces
```
}

?>
```
and voilà... so, what’s the big deal about this???

the end ?> gave problems for a lot of users. the headers already send error was most of the times caused by adding ?>.

It isn’t needed in php only files so why not?

In the most of cases, ?> sign inside of php file is just a waste of time, and can lead to bugs and security injects.

1.) If there are no HTML blocks outside of <?php ?> block you dont need it.

For example:

Here you need ?>
```
<?php

class Test{

}
?>
<html></html>
```
Here you don’t need to:
```
<?php

class Test{

}
```
2.) GZIP will fail, headers will fail if something is wrong or to be exactly output before code execution.

3.) Because there are a lot of <?php ?><?php ?><?php ?><?php ?>, you can get injected to insert something between ?> and <?php

That’s what I know about that “problem”.
