How to get apache's version?

Question

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

That function is only available if PHP is compiled and installed as a normal Apache module. If it's not, well, this happens. — Andrei, Feb 03 '17 at 10:19
Andrew I've read that on a website but how to get the version? — aqw alhadary, Feb 03 '17 at 10:21
You'll have to compile it yourself mate. See [here](http://dcx.sap.com/1200/en/dbprogramming/pg-php-compiling-apache.html) — Andrei, Feb 03 '17 at 10:22
Andrew I can't do that cause i don't have access to the terminal — aqw alhadary, Feb 03 '17 at 10:24
There's no way around it. Use the function you posted in your answer. — Andrei, Feb 03 '17 at 10:25

From the introduction to Apache functions:

These functions are only available when running PHP as an Apache module.

If you run PHP as CGI/FastCGI or any other SAPI, there's just no reliable way to determine Apache version because the interaction of PHP with Apache is minimum. If the server does not report it (thus you can read it somewhere at $_SERVER) you're out of luck.

You can also determine how PHP runs with phpinfo().

I can see that the Server's API is CGI/FastCGI – aqw alhadary Feb 03 '17 at 11:03

Maybe you could try

<?php
echo shell_exec('httpd -version');

Which OS are you using? – Michael Feb 03 '17 at 10:54
Michael I'm using windows but the host is using Linux I believe – aqw alhadary Feb 03 '17 at 10:56
So you have no access to terminal use? – Michael Feb 03 '17 at 10:57
Michael Nope but i can still run shell_exec – aqw alhadary Feb 03 '17 at 11:02
Can you do a echo shell_exec('php -v'); – Michael Feb 03 '17 at 11:09
For debian you need to use echo shell_exec(' apachectl -V'); – Michael Feb 03 '17 at 11:12
Michael tried that before it echo's information about PHP – aqw alhadary Feb 03 '17 at 11:12

You can use $_SERVER['SERVER_SOFTWARE'] To get the the web server you're running. As Andrew said you can compile it yourself from here. There's no way around it

This comes from the response headers. If the server does not report its version, you'll just get `Apache` or even nothing at all. – Álvaro González Feb 04 '17 at 09:02

To determine if you can read the Apache version, create a phpinfo.php file as mentioned by Álvaro González.

<?php phpinfo(); ?>

Run the file and if the PHP Variable $_SERVER['SERVER_SOFTWARE'] is listed with a value, use the following in your PHP code:

$apache_version = $_SERVER['SERVER_SOFTWARE'];
echo "$apache_version";

The reported value is dependent on the configuration and may not be listed at all. Otherwise you might get something like Apache/2.4.29 (Unix) or Apache/2.2.22 (Win64) etc.

echo apache_get_version();

It will print the Apache's complete version detail.
