In what ways can the use of sprintf function in PHP improve code readability and maintainability?

Using the sprintf function in PHP can improve code readability and maintainability by allowing for easier formatting of strings with placeholders for variables. This can make the code easier to understand and modify, as the format of the string is separated from the actual values being inserted. Additionally, sprintf can help prevent errors that may occur when manually concatenating strings and variables.

$name = "John";
$age = 30;

// Using sprintf for better readability and maintainability
$message = sprintf("Hello, my name is %s and I am %d years old.", $name, $age);

echo $message;
