What are the potential pitfalls of using double quotes ("") versus single quotes ('') in PHP when echoing HTML code?

Using double quotes ("") in PHP when echoing HTML code can lead to issues if the HTML code contains variables or special characters that need to be parsed. In such cases, using single quotes ('') can be more appropriate as it prevents PHP from parsing variables within the string. To avoid potential pitfalls, it's best to use single quotes when echoing HTML code that contains variables or special characters. 

// Example of using single quotes to echo HTML code with variables
$name = "John";
echo '<p>Hello, ' . $name . '</p>';
