Why is it important to include the </form> tag in PHP when generating forms dynamically, and how can this be implemented effectively to ensure proper form structure?

It is important to include the </form> tag in PHP when generating forms dynamically to ensure that the form structure is properly closed. This helps in maintaining the validity of the HTML code and ensures that the form functions correctly. To implement this effectively, you can simply concatenate the closing </form> tag at the end of the form generation code.

&lt;?php
// Form generation code
echo &#039;&lt;form action=&quot;submit.php&quot; method=&quot;post&quot;&gt;&#039;;
echo &#039;&lt;input type=&quot;text&quot; name=&quot;username&quot;&gt;&#039;;
echo &#039;&lt;input type=&quot;password&quot; name=&quot;password&quot;&gt;&#039;;
echo &#039;&lt;input type=&quot;submit&quot; value=&quot;Submit&quot;&gt;&#039;;
echo &#039;&lt;/form&gt;&#039;; // Closing form tag
