What are the potential pitfalls of using control structures within strings in PHP?

Using control structures within strings in PHP can lead to readability issues and make the code harder to maintain. It can also cause unexpected behavior if not used correctly. To solve this problem, it is recommended to break out of the string and use concatenation or interpolation to incorporate control structures. 

// Example of using concatenation to incorporate control structures
$name = "John";
$message = "Hello, " . ($name == "John" ? "John" : "Guest") . "! Welcome to our website.";
echo $message;
