In PHP, the printf() function is used to format and print output. It allows you to specify a format string and a variable number of arguments that will be inserted into the format string. Here's an example:

$name = "John";
$age = 25;

printf("My name is %s and I am %d years old.", $name, $age);

Output:

My name is John and I am 25 years old.

In the example above, %s is used to insert the value of $name as a string, and %d is used to insert the value of $age as a decimal number. The order of the arguments in the printf() function must match the order of the placeholders in the format string.
