In what ways can PHP updates or upgrades impact the functionality of installed modules and extensions like templates?

When PHP is updated or upgraded, it can sometimes lead to compatibility issues with installed modules and extensions like templates. To solve this issue, it is important to ensure that the modules and extensions are also updated to be compatible with the new PHP version. This can involve checking for updates from the module or extension developers, or manually updating the code to be compatible with the new PHP version.

// Example of updating a module or extension to be compatible with a new PHP version

// If no updates are available, manually update the code to be compatible with the new PHP version
