how do i find out what files is in a folder and how many files there are
because i'm making a php photo album with pictures in a folder and i want it to find out what is in the folder and display it

i know how to find out how many there are with count()
i know how to display it if it's like this name[1]

so if you can so me how to make it put the name of each file in name[1] name[2]
than that is all i need to know

Hi MrGecko,

First, loop through your folder and assign images to an array:

$pictures = array();
$folder = opendir("pictures/");
while ($read = readdir($folder))
{
if ($read!= "." && $read!= "..")
{
$pictures[] = $read;
}
}
closedir($folder);

There are <?php echo count($pictures);?> pictures.

Then use a for loop for retrieve them. You can also use a foreach loop if you want, but for loops are more fun. :)

if (!empty($pictures))
{
for ($i=0; $i<count($pictures); $i++)
{
echo $pictures[$i]." ";
}
}

Or you can access them individually. Only recommended if you know how many there are or else you will get a undefined offset error.

echo $pictures[1];
echo $pictures[2];

Finally, view the contents of your array like this:

print_r($pictures)

glob [us3.php.net] is a very useful function:


$path = "directory/path";
$files = glob($path.'/*.*');
echo '<pre>';
print_r($files);
echo '</pre>';
echo '<br/><br/>';
$num_files = count($files);
echo 'There are '.$num_files.' in this directory: '.$path;

If you don't like this solution, take a look at readdir [us3.php.net].

Good luck :)

You can always sort [us2.php.net] the array.

You need to use a natural sort (natsort()) to get numbers in order of size.

Good catch, alfaguru. Thanks ;)

with sort(); and sort(natsort());
both did not work this is the output
Pictures-Thumbnails/0.jpg
Pictures-Thumbnails/1.jpg
Pictures-Thumbnails/10.jpg
Pictures-Thumbnails/11.jpg
...

it is not outputting in order
can some make it work
this is my script
$file = glob("Pictures-Thumbnails".'/*.*');
sort (natsort($file));

Don't sort [php.net] the natsort again, you are resetting it! OT: Some side notes on the use of glob ->

print_r [php.net] is your friend here. It will dump the contents of an array in a nice, readable format if you enclose it in HTML <pre> elements. First, make sure your array is coming out in the order you like by dumping it to the browser. Note the inserted code in bold here ...

<? 
$do = isset($_REQUEST['do'])? $_REQUEST['do'] : 1; 
switch ($do) { 
case "Picture": 
$file = glob("Pictures-Images/*.jpg"); 
natsort($file); 
print '<pre>'; print_r($file); print '</pre>'; exit; 
$Picture = isset($_REQUEST['Picture'])? $_REQUEST['Picture'] : 1; 
?>

If this looks correct, then somewhere in your code you are altering your logic to display the results in a different order.
