What are the potential pitfalls of mixing PHP variables with HTML code in echo statements?

Mixing PHP variables with HTML code in echo statements can make the code harder to read and maintain. It can also introduce security vulnerabilities if the variables are not properly sanitized. To solve this issue, it's recommended to separate the PHP logic from the HTML code by using concatenation or interpolation to insert variables into the HTML. 

<?php
// Example of separating PHP variables from HTML code using concatenation
$name = "John";
echo "Hello, " . $name . "!";

// Example of separating PHP variables from HTML code using interpolation
$name = "Jane";
echo "Hello, $name!";
?>
