 outputing number of files in a directory
Hey, I want to put a little thing on imghoster to say how many images are hosted.
e.g. "currently hosting xx images"
In the folder where the images are hosted, there are 2 files which must not be counted.
Thanks,
Gethn.

Code:
<?php
//get path of directory containing this script
$dir = $_SERVER['DOCUMENT_ROOT'].dirname($PHP_SELF);
//open a handle to the directory
$handle = opendir($dir);
//intitialize our counter
$count = 0;
//loop through the directory
while (false !== ($file = readdir($handle))) {
//evaluate each entry, removing the . & .. entries
if (is_file($file) && $file !== '.' && $file !== '..') {
$count++;
}
}
echo $count;
?>

Thanks Blue Ire, I just tried that and it outputted 12... which is incorrect.
Im guessing it's counting the number of files in the public_html directory.
What code to I change to change the directory it counts the files in, and then how do I minus 2 for the total number of images hosted?
Cheers!

Change:
$dir = $_SERVER['DOCUMENT_ROOT'].dirname($PHP_SELF);
to:
$dir = "/your/path/here/";
And you should be golden.

I don't know if what you're trying to achieve would work with something this simple, but if you're looking to grab the images files from a directory then you could possibly look to using:
PHP Code:
<?php
// Find all jpg, gif or png files in the images sub-directory
$files = glob('./images/*.{jpg,gif,png}', GLOB_BRACE);
echo 'There are ' . count($files) . ' images.';
?>

Andrew R I tried that, had an error thought.
Salathe I have used your code, and it works... however it is not counting all the images, it's deducting 11 from the real number.

My script only catches files ending in .jpg .gif or .png. If there are other file extensions that you want to count then you'll need to add those in as well.
