Printf()

Our article is about the PHP function printf(), which is used to output a formatted string. This function is similar to the echo() function in PHP, but allows for more precise formatting. In this article, we will discuss the syntax and usage of printf(), as well as provide some examples.

The printf() function is used to output a formatted string. The syntax of the printf() function is as follows:

int printf ( string $format , mixed ...$args )

The function takes two parameters, $format and $args. The $format parameter is a string containing format specifiers, and the $args parameter is a variable number of arguments to be formatted and inserted into the format string.

Here is an example of how to use the printf() function:

<?php
$name = 'John Doe';
$age = 35;
printf('My name is %s and I am %d years old.', $name, $age);
?>

In this example, we use the printf() function to output a formatted string containing the variables $name and $age.

The output of this code will be:

My name is John Doe and I am 35 years old.

As you can see, the printf() function has output the formatted string with the variables inserted in their respective format specifiers.
