Sample Output

Save PHP file with a “.php” file extension. For example, This tutorial uses “test.php”. PHP file should be deployed to the server in order to run. The exact path may vary from server to server. On Apache web server it is usually the htdocs folder. Deploy the file to the folder.

PHP Script Syntax

We can access the file from the web browser by typing the URL in the address bar.

http://localhost/test.php

The string localhost refers to the server running on your own machine. We can also refer to the local server is by using the loopback IP address: 127.0.0.1

http://127.0.01/test.php

The server runs on the default HTTP port 80. Incase the server runs on a different port we can append the port to the address. For example, if the server runs on 8080 port, we can access the URL as:

http://localhost:8080/test.php
