Question

I’m building a counter that counts and displays on a web page the number of images in a certain directory.

The code I’m currently using is this:

<?
    $d = opendir("images/myimagefolder");
$count = 0;
     $min_digits = 7;
while(($f = readdir($d)) !== false)
  if(ereg('.jpg$', $f))
     ++$count;
closedir($d);
 if ($min_digits)
{
  $count = sprintf('%0'.$min_digits.'f', $count);
}

$number = $count;
$formattedNumber = sprintf("%07d", $number);
$formattedNumber = str_split($formattedNumber, 3);
$formattedNumber = implode(",", $formattedNumber);

  print "$formattedNumber";
?>

This works well and outputs a number like the following: 000,000,5

What I am wanting is to have the separating commas occur every 3 digits from the right not the left, so it would appear as 0,000,005

How would this this be done?

I have tried a number of modifications to my sprintf and str_split code but nothing has worked so far. Any help would be greatly appreciated!

Answer 1

<?php

//image count
$images=count(glob("images/myimagefolder/*.jpg"));

//padding
$images=sprintf("%07s",$images);

//commas
$images=strrev(implode(",",str_split(strrev($images),3)));

//outputs 0,000,005
echo $images;

?>

Had a bit of fun coming up with the shortest possible way to accomplish your solution. 🙂
