How does the placement of single and double quotes affect PHP value passing using <a href>?

When passing PHP values using <a href>, single quotes should be used to wrap the HTML attribute values to prevent interference with PHP variables. Double quotes should be used within the PHP code to properly parse variables. Mixing single and double quotes can lead to syntax errors or unexpected behavior. 

&lt;?php
$id = 123;
$name = &quot;John&quot;;

echo &#039;&lt;a href=&quot;profile.php?id=&#039; . $id . &#039;&amp;name=&#039; . $name . &#039;&quot;&gt;View Profile&lt;/a&gt;&#039;;
?&gt;
