RE: “How do I know which PHP version I’m using?”
When logged in to the server
php -v
will show you the PHP version information
Here’s a quick cheat sheet that shows the base versions of PHP offered in some major distros:
| Distro | PHP Version |
|---|---|
| Ubuntu 12.04 | 5.3.10 |
| Ubuntu 14.04 | 5.5.9 |
| Ubuntu 16.04 | 7.0 |
| CentOS 6 | 5.3.3 |
| CentOS 7 | 5.4.16 |
| Debian 7 | 5.4.45 |
| Debian 8 | 5.6.20 |
If you need a more recent version, there are a number of third party repositories that offer them. For instance, these articles will walk you through upgrading to PHP 7 on Ubuntu 14.04 and CentOS 7:
