How can the use of echo statements be optimized to improve code readability in PHP?

Using echo statements excessively can clutter the code and make it harder to read. To improve code readability, it's recommended to use echo statements only when necessary and to concatenate strings instead of using multiple echo statements for each piece of content.

// Instead of using multiple echo statements, concatenate strings for better readability
$name = "John";
$age = 30;
echo "Name: " . $name . ", Age: " . $age;
