Question

I’m from a C background and understand basics of printf function.

I came across the follwing code

<?php
printf('%4$d %2$s code for %3$3.2f %1$s', "hours", "coders", 9, 99);
?>

which prints:

99 coders code for 9.00 hours

Can anyone help me in understanding the call to the printf function.

<n>$ means “use the nth argument, instead of whatever position you are in formatting specs”.
