On the Site Settings page you can pick a different PHP version.

Click 'Save Changes' to apply the PHP version change.

### What versions are supported?

We follow the official PHP support policies detailed on [https://www.php.net/supported-versions.php](https://www.php.net/supported-versions.php).

You can view the supported versions on the Site Settings page.

If you require another version of PHP to be installed, please contact Support who can arrange this.

### Using the CLI

To switch PHP versions on Cito sites, use the `phpmgr` utility:

```
cito~ # phpmgr
Usage: phpmgr -d <domain> -s <version>

  -d: Domain name (required).
  -s: <version> Set PHP version.
  -l: List available PHP versions.

Example: phpmgr -d test.com -s 8.2
(Sets the domain test.com to PHP 8.2).
```

The script automatically updates configuration files and switches to the new version. It will output the available versions and warn if you are trying to use one that is not available.

## Command-line PHP

It's important to note that if you're using a different PHP version in your CLI scripts you'll need to either reference that version's binary directly, or add an alias to your `bash_profile` to switch to it.

For example, if your server has a default version of PHP 7.4 but you're using PHP 8.0, you will need to invoke it at the command-line as follows:

```bash theme={null}
/usr/bin/php8.0 <command>
```

You can also add an alias for `php` to your bash\_profile as follows:

```bash theme={null}
echo "alias php='/usr/bin/php8.0'" >> ~/.bash_profile
```

(Substituting the version appropriately).
