How to Check PHP Version on Server

Enter the following code. When run on your server, this little code will return PHP's version information.
Save as PHP file. Click "File" → "Save as" and give the file a name. Add the .php extension to the end of the name. Choose a simple name, such as version.php.
Generate a more detailed report (optional). The file above will tell you what the current version of PHP is. However, if you want more information, such as system information, release date, available commands, API information, etc., you can use the phpinfo() command. Save the file with the name info.php.
Upload your file(s) to the server. You will probably have to use an FTP client program. You can also get it through your server's admin console. Leave the file in the root directory of your server.
Refer to the article on how to upload files to your server.
Open the file in your browser. Once the files have been uploaded to the server, you can use your browser to upload them. Find the file location on the server. For example, if you leave them at the root of your domain, go to www.yourdomain.com/versions.php.
