Count Images in a Folder

[foochuck]

I have a folder on my website - I'd like to use PHP to count the number of jpgs in that folder. The folder is called thumbnails. Could someone show me how this is done?

 

Thanks

Something like

<?php

$imgCount = 0;

foreach (glob("./thumbnails/*.jpg") as $image)
{
    $imgCount++;
}

echo 'There are ' . $imgCount . ' JPEG\'s in thumbnails/';

?>

Thanks wildteen that works great.

 

I have a couple of questions...

 

1. "glob() as $image) - could you explain that part to me?

 

2. Why do I need the period ("./thumbnails/*.jpg") before the thumbnails folder?

 

Thanks again!

1. "glob() as $image) - could you explain that part to me?

That is the syntax for a foreach loop. glob returns an array of files matching the pattern.

 

Here are links to the manual on foreach and glob

 

2. Why do I need the period ("./thumbnails/*.jpg") before the thumbnails folder?

The . at the beginning of file paths tells PHP to go from the current working directory (where the executing script is). I always tend to add ./ to beginning of file paths, just a habit. You can remove ./ if you want to.

Awesome. Thanks wildteen.

 

One other question - could I use this same type of format to not only count the images in that folder, but grab their actual filenames? (boy.jpg, girl.jpg, 1.jpg, DSC0099.jpg, etc)...?

Yes. the $image variable holds the filename

 

Note: You cannot use the $image variable outside of the loop.

 

 

<?php

$dir = './thumbnails/'
$imgCount = 0;

foreach (glob($dir . '*.jpg') as $image)
{
    $imgCount++;

    echo '<b>Name</b>: ' . $image . '<br />';
    echo '<b>Size</b>: ' . filesize($dir . $image) . '<hr />';
}

echo 'There are ' . $imgCount . ' JPEG\'s in thumbnails/';

?>

If you just want the count, you don't need the foreach loop at all:

<?php
$dir = './thumbnails/'
echo 'There are ' . count(glob($dir . '*.jpg')) . " JPEG's in the directory thumnails/";
?>

Thanks kenrbnsn - this one is a lot cleaner.

<?php
$dir = './thumbnails/'
echo 'There are ' . count(glob($dir . '*.jpg')) . " JPEG's in the directory thumnails/";
