How can one properly format a string in PHP for later use with printf()?

When formatting a string in PHP for later use with printf(), you need to use placeholders such as %s for strings, %d for integers, and %f for floating-point numbers. These placeholders will be replaced with the actual values when using printf(). Make sure to escape any special characters in the string using double quotes. 

$name = "John";
$age = 30;
$height = 5.9;

$string = "Name: %s, Age: %d, Height: %.1f";
$formattedString = sprintf($string, $name, $age, $height);

echo $formattedString;
