How to determine whether php is apache or nginx

1. 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.

2. 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.".
