How can PHP and HTML be effectively connected in a web development project?

To effectively connect PHP and HTML in a web development project, you can use PHP to generate dynamic content within HTML files. This can be done by embedding PHP code within HTML using opening and closing PHP tags <?php ?>. This allows you to mix PHP logic and HTML markup seamlessly, creating dynamic and interactive web pages.

&lt;!DOCTYPE html&gt;
&lt;html&gt;
&lt;head&gt;
    &lt;title&gt;PHP and HTML Example&lt;/title&gt;
&lt;/head&gt;
&lt;body&gt;
    &lt;h1&gt;Welcome, &lt;?php echo &quot;John Doe&quot;; ?&gt;&lt;/h1&gt;
    &lt;p&gt;Today&#039;s date is &lt;?php echo date(&quot;Y-m-d&quot;); ?&gt;&lt;/p&gt;
&lt;/body&gt;
&lt;/html&gt;
