I written the following tiny php program to test printf and sprintf:

<?php
    $text = "65 127 245";
    $str_1 = printf("%x%x%x", 65, 127, 245);
    $str_2 = sprintf("%x%x%x", 65, 127, 245);
    
    echo $str_1 . "\n";
    echo $str_2 . "\n";
?>

the output is this:

417ff56
417ff5

why I have that 6 digit in the first line of output?
