this is a really noob question I guess, but I am very new to php and have no idea how to even begin this one, basically I have a set of $vars that I have to display the length of as a 3 digit number that is right justified.

Any pointers as to how to do this?

Many thanks for all your help.

Answer 1

This should take care of what you just described in your comment:

echo str_pad(strlen("hello"), 3 , "0", STR_PAD_LEFT);

This will return

005

Answer 2

Your answer lies within PHP documentation: http://php.net/manual/en/function.str-pad.php

From their example:

<?php
$input = "Alien";
echo str_pad($input, 10);                      // produces "Alien     "
echo str_pad($input, 10, "-=", STR_PAD_LEFT);  // produces "-=-=-Alien"
echo str_pad($input, 10, "_", STR_PAD_BOTH);   // produces "__Alien___"
echo str_pad($input, 6 , "___");               // produces "Alien_"
?>

Answer 3

The printf version:

printf("%40d", 123); //                                      123

40 chars right justified
