How can the use of variables instead of direct echo statements improve the structure and clarity of PHP code?

Using variables instead of direct echo statements can improve the structure and clarity of PHP code by making it easier to read and understand. By assigning values to variables and then echoing those variables, the code becomes more organized and easier to maintain. Additionally, using variables allows for easier debugging and troubleshooting as the values can be easily tracked and modified. 

// Direct echo statement
echo "Hello, World!";

// Using variables for improved structure and clarity
$message = "Hello, World!";
echo $message;
