Change the PHP version and settings

Before changing PHP

• Check the application, framework, theme and plugin requirements.
• Create a current backup and use staging for a major-version change.
• Update abandoned extensions or replace them before removing the PHP version they require.
• Record any custom extensions and values already in use.

Change the website PHP version

1. Open the website in Enhance and choose Developer tools or PHP.
2. Select the target version available on the server.
3. Save the change and allow the website container to reload.
4. Test public pages, administration, forms, scheduled tasks and checkout.
5. Review the application log for deprecation notices or fatal errors.

Adjust limits only for a reason

• memory_limit affects how much memory one PHP process may use.
• upload_max_filesize and post_max_size must both accommodate the upload.
• max_execution_time can help a legitimate long task, but increasing it will not fix a loop or external timeout.
• Package or server limits can cap customer-editable values. Contact support if Enhance refuses the required setting.
