In what scenarios would using printf be more advantageous than using echo in PHP scripts?

Using printf in PHP scripts can be more advantageous than using echo in scenarios where you need to format output with specific placeholders, such as when outputting variables within a string. printf allows for more control over the formatting of output, including specifying the number of decimal places for floating point numbers or padding strings to a certain length. Additionally, printf can be more efficient when outputting a large amount of data since it only parses the format string once. 

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

// Using printf to format output with placeholders
printf("Name: %s, Age: %d", $name, $age);
