What are the advantages and disadvantages of using sprintf() in PHP to replace strings with variables?

When replacing strings with variables in PHP, using sprintf() can provide a cleaner and more readable way to format the output. It allows for placeholders to be easily replaced with variables, making the code easier to maintain and understand. However, overusing sprintf() can lead to a cluttered codebase and reduce readability, so it's important to use it judiciously. 

$name = 'John';
$age = 30;

// Using sprintf() to replace strings with variables
$output = sprintf('Hello, my name is %s and I am %d years old.', $name, $age);

echo $output;
