Determine the version of PHP running a website via PHP code

Upgrade Help & FAQs > How to clarify your webserver PHP version

Setup a PHP Info file

It's possible to create a very simple file that you can upload to your web space that will output a list of environment settings about your web server's PHP environment. This step requires that you have access to upload a file to your public web space (either via FTP or a Control Panel website).

If you are at all uncomfortable uploading a file to your live website it is probably time to either

1. Contact your internet service provider for help to determine your PHP version
2. Find a developer to help you clarify this and undertake any update required.

Creating a phpinfo script

Assuming you are comfortable uploading a file to your web hosting just follow these very simple steps...

1. Create a text file on your computer containing only the following line of code within it:
   
   <?php phpinfo(); ?>
2. Save the file as something unique that ends with the .php extension. For example myphpversion.php
3. Copy this file up to your web hosting space
4. Now access it via a web browser at your domain name. Ie: http://yourdomain.com/myphpversion.php
5. You should now see a white page with a large purple table. At the top of this your exact PHP version will be shown.
6. Finally, very importantly; delete the file you just uploaded!
