How can PHP be used effectively in conjunction with XHTML?
PHP can be used effectively in conjunction with XHTML by embedding PHP code within the XHTML file using the `<?php ?>` tags. This allows for dynamic content generation and manipulation within the XHTML document. Additionally, PHP can be used to interact with databases, handle form submissions, and perform other server-side tasks to enhance the functionality of the XHTML page.
