What are the potential pitfalls of using both single and double quotes in PHP code?

Mixing single and double quotes in PHP code can lead to confusion and errors, especially when trying to concatenate strings. It is recommended to choose one style consistently throughout your code to maintain readability and prevent unexpected behavior. If you need to include quotes within a string, you can escape them using a backslash (\). 

// Example of using consistent double quotes
$name = "John";
$message = "Hello, $name!";

echo $message;
