# How to change PHP versions in SiteWorx

## Prerequisites

- SiteWorx allows you to change your PHP version as needed. All PHP applications and commands run from this account will use this version of PHP.
- You must have a Nexcess account on a physical (non-cloud) server. If you are a Cloud client, instead see [How to change PHP versions in Nexcess Cloud](https://docs.nexcess.com/sites-stores/managed-magento/store-management/adjust-php-version/).

## Step by step instructions 

SiteWorx allows you to change your PHP version at will. All PHP applications and commands run from this SiteWorx account will use this version of PHP.

Compatibility Issues

Before changing versions, verify the compatibility of your applications, or the changes may adversely affect your security and performance.

1. Log in to your SiteWorx account. 
    - If you do not know your password, click **Forgot Your Password?** on the login page.

2. From the SiteWorx main menu, click **PHP** **Version**.
3. From the **Update** **PHP** **Version** drop-down list, click your desired version, then click **Select** . You have now changed the PHP version for your account, and these effects take place immediately.
