How do you want them to be sorted?

I've just written this for you, hopefully it will do the trick.  It's a function that returns the last 10 files modified in a given directory.  It has an optional parameter so you can specify how many files to return, if left blank, it defaults to 10.  The files are returned sorted in descending order.  You could list the files using a foreach loop.

E.G:

$files = list_files ("C:\\");
foreach ($files as $k => $v) {
    echo "$v<br />\n";
}

Hope this helps.

More Example Usage:

print_r ( list_files ("C:\\"));    //  Lists the last 10 modified files in the C:\ drive.
print_r ( list_files ("C:\\Program Files\\", 20));   // Lists the last 20 modified files in Program Files


<?php
	
	function list_files ($string_dir, $int_limit = 10) {
		$files = array();
		//	Get all the files in the directory, along with the last modified date.
		if ($dir_handle = opendir ($string_dir)) {
			while (false !== ($file = readdir ($dir_handle))) {
				$files[date("YmdHis", filemtime($string_dir . $file))] = $file;
	    	}
	    	krsort ($files);
	    	$files = array_chunk ($files, $int_limit, true);
	    	return $files[0];
		}
		return false;
	}
?>

in this query the file_name represent the file name but the problem is the pdf_files includes all the files name either exist or not so when I excute the query it return all files name but  they're not physically exist
so I need to return file_name physically exist only in the directory

SELECT      file_name  FROM pdf_files;

file_name from the database
101
102
103
104
105

but what's in the directory is till 103 only so in the query return only up to 103.pdf  

Thanks

OK.  You can use the file_exists function with a loop and break out of it once you find a file that isn't found.  The snippet below should send you in the right direction, you will need to change the file_exists part where it says path to point to your directory where the PDF files are stored.

Hope this helps.
<?php
	
	$query = "SELECT file_name FROM pdf_files";
	while ($row = mysql_fetch_array($query)) {
		if (file_exists('path' . $row['file_name'] . '.pdf')) {
			echo $row['file_name'] . "<br />\n";
		} else {
			break;
		}
	}
	
?>
