Get the web server version in PHP

I would like the version of a web server (Nginx, MySQL, MariaDB, ...) in PHP.

I know the function for Apache: apache_get_version(). There are many phpinfo() which returns all values but how to exploit?

You would have an idea or it is not possible for the moment?

To query the version of MySQL and/or MariaDB in PHP, you could use mysqli_get_server_info() or (if you are still using the older mysql API which was deprecated in PHP 5.5.0 and removed in PHP 7.0.0) mysql_get_server_info(). The PDO API has no similar function or class for that purpose, but in that case you could just use the result of the SQL query

SELECT VERSION();

It returns something like 5.5.50-0+deb7u2. Here's a quick example:

<?php
  $user = 'username_here';
  $pass = 'your_db_password';
  // create DB connection
  $dbh = new PDO('mysql:host=localhost;dbname=mysql', $user, $pass);
  $stmt = $dbh->query('SELECT VERSION();');
  //fetch first column of first result row and print it out
  echo $stmt->fetchColumn();
  //unset PDOStatement and PDO to close DB connection
  unset($stmt);
  unset($dbh);
?>

The other answers mention different methods on how to get the web server and database versions, however there is a function which will get the operating system itself.

// Gets the "System" row shown at the top of the `phpinfo()` table.
$system = php_uname( $mode = 'a' );

You can specify the mode to select different components. By default it'll display all of the components, separated by spaces and in the following order:

  • s: Operating System Name
  • n: Host name
  • r: Release Name
  • v: Version Information
  • m: Machine Type

You can view more information about the php_uname function here.

You can retrieve the web server's version by using the $_SERVER superglobal, more specifically by using:

 $_SERVER['SERVER_SIGNATURE']

As per PHPs Documentation:

SERVER_SIGNATURE

String containing the server version and virtual host name which are added to server-generated pages, if enabled.

You can find more info on the official PHP Documentation site: http://php.net/manual/en/reserved.variables.server.php

A simple shell_exec would do the trick (assuming you're on a unix based server). Just don't put any user data into the command, and be aware that this approach may not work in shared hosting environments:

$nginxVersion = shell_exec('nginx -v 2>&1');
$mysqlVersion = shell_exec('mysql --version');

Note that nginx sends version output to stderr, so you need to pipe it to stdout to capture it.

Address the $_SERVER super-global http://php.net/manual/en/reserved.variables.server.php

I believe the setting you want is: 

echo $_SERVER['SERVER_NAME'];
