What are the best practices for formatting echo statements in PHP to ensure readability and maintainability of code?

When using echo statements in PHP, it is important to format them properly to ensure readability and maintainability of the code. One best practice is to use double quotes for strings that contain variables so that the variables are interpolated correctly. Additionally, breaking long echo statements into multiple lines can improve readability. Lastly, using concatenation when necessary can make the code more organized. 

// Example of properly formatted echo statements
$name = "John";
$age = 30;

// Using double quotes for string interpolation
echo "Hello, $name! You are $age years old.";

// Breaking long echo statements into multiple lines
echo "Lorem ipsum dolor sit amet, consectetur adipiscing elit. ";
echo "Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.";

// Using concatenation when necessary
echo "This is a long string that needs to be concatenated with " . "another string for better readability.";
