$n = 123;
$f = 123.45;
$s = "A string";
printf ("%d", $n); // prints 123
printf ("%d", $f); // prints 123
// Prints "The string is A string"
printf ("The string is %s", $s);
// Example with precision
printf ("%3.3f", $f); // prints 123.450
// Complex formatting
function showError($msg, $line, $file)
{
return sprintf("An error occured in %s on ".
"line %d: %s", $file, $line, $msg);
