Seperate directory reading

Good day to you all,
I was wondering how to seperate the result of a direcory read.
Example, I know the files will be images.

How can I show the portrait first and then landscape second ?

here is my code :

PHP Code:


			


<html>
<head>

    <SCRIPT language="JavaScript">
    <!--
    if (document.images)
    {
      preload_image = new Image(25,25); 
<?PHP
//  directory name sent by url
$dir = $_GET['dir'];
$file = $_GET['file'];

//define the path as relative
$path = $dir."".$file;

//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

echo "Directory Listing of $path<br/>";

//running the while loop
while ($file = readdir($dir_handle)) 
{
   if($file!="." && $file!="..")
    
      echo "preload_image.src=\"http://test.peuplies.info/PHP/Photos_gallery/".$path."/".$file.""; 

}

echo "} //-> </script> </head> <body><center>";



while ($file = readdir($dir_handle)) 
{
   if($file!="." && $file!="..")
    
      echo "<img src=\"".$path."/".$file."\" width=\"50px\">"; 

}







//closing the directory
closedir($dir_handle);


?>



</center>

</body>
</html>

Thanks!

With all of these threads about reading files from a directory, please start separating your code into specific tasks. For this particular thread:

Gather list of images in the directory
Iterate over that list ordering by orientation (landscape/portrait)
Display that sorted list in your required format (JavaScript in this case)

To help you determine which images are landscape or portrait you could use the getimagesize function.
