How to Tell If PHP Is Running in CGI Mode?

The "phpinfo()" function lets you run a script on a PHP server to identify if the server runs in CGI mode. CGI is an older form of execute that let you run scripts on a Web server. You must create a PHP file that contains the phpinfo function on your Web server. The server returns a response that includes a Server API section that tells you if the server runs in CGI mode.

Instructions

1. Select the Windows Start button and type "notepad" in the search text box. Press "Enter" to open the Notepad text editor.

2. Type the following code in the file:

   <?php phpinfo() ?>

3. Click the "File" menu item and select "Save." Type "info.php" in the File Name text box. Select "All Files" from the drop-down box. Click "Save" to save the file.

4. Upload the file to your Web host server. The server information is included with your Web host account. Upload the file to the root directory on your server.

5. Open a Web browser and type your domain name and the file "info.php" in the address text box. A list of information displays. Review the section labeled "Server API" to identify if the PHP engine runs in CGI mode.
