How can you display a telephone number in a page footer using Admin functionality?

To display a telephone number in a page footer using Admin functionality, both specifying the phone number for the store and enabling its display in the footer using the appropriate variable are essential steps.

When you specify the phone number for the store in the Admin settings, you are establishing the information that will be displayed. This is typically done in the configuration settings, allowing for easy updates in the future without the need for altering code.

Additionally, using the appropriate variable to enable its display in the footer ensures that the system is programmed to show this information at the designated location on the page. This allows for a dynamic display that updates automatically if the phone number is changed in the store settings.

Together, these methods leverage the built-in functionality of Magento, promoting best practices that avoid custom coding where possible and enhance maintainability. This dual approach is significant in leveraging Magento's flexibility while ensuring that the footer is informative for users visiting the site.
