loop to find out how many pictures are in a folder ?

[pooker]

How would I go about doing this ? I basically want it to find out how many images are in a folder, is this how I would do it? 

all of the images are named like B-1 etc, etc

$number = 1;

while(http://url.com/folder/B-$number.jpg = true)

{

$number=$number + 1;

}

echo 'there are' . $number 'in this folder';

?>

you can use scandir() to scan the files in the files. then you can check the file types using filetype().

Also, it can't be used on a remote directory, but locally its simple....

 

<?php echo count(glob('/path/to/images/B*jpg')); ?>

Further supporting current suggestions, multiple image types:

<?php
  echo count(glob("{*.jpg,*.JPG,*.png,*.PNG,*.gif,*.GIF}", GLOB_BRACE));
?>

Thanks guys, no matter which way I set it up it still sees it as zero though any reason? 

 

Here is what I used , I tried with the glob and without, the reason I did without is because each of these directories just stores images.

 

<?php

$dir = './bleach/chapter1/';

$total = count($dir) ;

echo 'There are ' . $total . ' images';

?>

Look at the replies, then look again at your code.

i suppose that should be:

 

$total = count(scandir($dir)); // returns the number of files

 

instead of:

 

$total = count($dir); // returns 1

 

or alternatively, here is a little mod of the previous ones

 

<?php
$dir = "./images/"; // replace this with the path where the images are stored
foreach (glob("{$dir*.jpg,$dir*.JPG,$dir*.png,$dir*.PNG,$dir*.gif,$dir*.GIF}", GLOB_BRACE) as $filename) {
// do whatever you want here
}
?>

ooops... replace:

 

glob("{$dir*.jpg,$dir*.JPG,$dir*.png,$dir*.PNG,$dir*.gif,$dir*.GIF}", GLOB_BRACE)

 

with:

 

glob("{".$dir."*.jpg,".$dir."*.JPG,".$dir."*.png,".$dir."*.PNG,".$dir."*.gif,".$dir."*.GIF}", GLOB_BRACE)
