PHP is a popular language used for web development. Among web servers, Apache and Nginx are two common web servers. When developers prepare to use PHP for web development, they sometimes need to know whether their web server is Apache or Nginx.
In this article, we will explore how to write code using PHP to detect whether the web server is Apache or Nginx. We will introduce how to detect both web servers separately.
- Detecting Apache
Apache is widely used and is the most popular web server among Linux and Unix servers. If your PHP code is running on an Apache server, you can use the following code to detect:
if (strpos($_SERVER['SERVER_SOFTWARE'], 'Apache') !== false) {
echo "This server is running Apache.";
} else {
echo "This server is not running Apache.";
}
This code uses the server variable $_SERVER['SERVER_SOFTWARE'] to detect the software type of the server Whether to include "Apache". If included, the code prints "This server is running Apache."; otherwise, it prints "This server is not running Apache.". Note that this code also uses !==false instead of ==true to avoid returning an incorrect value.
- Detect Nginx
Nginx is another popular web server that is also popular among developers. Detecting Nginx is slightly different than detecting Apache. The following code can be used to detect Nginx:
if (strpos($_SERVER['SERVER_SOFTWARE'], 'nginx') !== false) {
echo "This server is running Nginx.";
} else {
echo "This server is not running Nginx.";
}
Similarly, this code uses the server variable $_SERVER['SERVER_SOFTWARE'] to check whether the server's software type contains "nginx". If included, the code prints "This server is running Nginx."; otherwise, it prints "This server is not running Nginx.".
Summary
In web development, knowing what web server you are using can help you understand the performance and security of your PHP applications. As described in this article, code written in PHP can easily detect whether the web server is Apache or Nginx. No matter which web server you use, these codes will provide you with useful information.
