What are some best practices for utilizing sprintf() effectively in PHP scripts to improve code readability and maintainability?

Issue: When using sprintf() in PHP scripts, it is important to follow best practices to improve code readability and maintainability. One way to do this is by using named placeholders instead of numerical placeholders, which can make the code more self-explanatory and easier to understand. Code snippet: 

// Using named placeholders with sprintf() for improved readability
$name = 'John';
$age = 30;

// Bad practice: numerical placeholders
$message = sprintf('Hello, %1$s! You are %2$d years old.', $name, $age);

// Good practice: named placeholders
$message = sprintf('Hello, %(name)s! You are %(age)d years old.', ['name' => $name, 'age' => $age]);
echo $message;
