When I try to run `apache_get_version()` function on my website, I get an error: 

> 
> **Fatal error:** Uncaught Error: Call to undefined function apache\_get\_version() in /srv/www/mywebsite.com/index.php:44 Stack trace: #0 {main} thrown in /srv/www/mywebsite.com/index.php on line 44

However this works in my localhost.
I tried 

```
function apache_version()
{
    $ver = explode(" ",$_SERVER["SERVER_SOFTWARE"],3);
    return ($ver[0] . " " . $ver[1]);
}
echo apache_version();

```

This should echo the server version on apache though it doesn't echo the version
