Hello, i am reading the files of a remote server directory and i am able to get results as can be seen from var_dump(). However i am having some trouble to create a md5_file() from the array given. Thank you for your assistance in this matter!
<?
		// Open a session to an external ftp site
		$ftp_server = 'ftp.mywebsite.com';
		$ftp_user_name = 'user@mywebsite.com';
		$ftp_user_pass = 'mypass';
		$ftp_port = '21';
		$remote_dir1 = 'public_html/dir1';
		// set up basic connection
		$conn1 = ftp_connect($ftp_server)or die("Could not connect to {$ftp_server}\n");
		$login_result1 = ftp_login($conn1, $ftp_user_name, $ftp_user_pass)or die("Could not login with {$ftp_server}\n");
		$dir1 = ftp_nlist($conn1, $remote_dir1)or die("Could not login with {$remote_dir1}\n");
		// output $contents
		var_dump($dir1);
		
		
		if(ftp_pwd($conn1)) {
		 foreach($dir1 as $file1) {
            //loop through it
                $hash = md5_file($conn1.$remote_dir1."/".$file1);
				$d[$hash] = $file1;
				}
			}
	
		else { 
			echo "Failed - Is not readable";
			}
?>

Try this:
$hash = md5_file($remote_dir1."/".$file1);

You may need to check if $file1 is a file or directory, you can use ftp_size function, if it returned -1 then it is a directory.

if (ftp_size($conn1, $file)!==-1)
     $hash = md5_file($remote_dir1."/".$file1);

Thank you for your response, i tried the code as you mention, but still there is no md5 results.

this is only results i am getting:

array(10) { [0]=>  string(1) "." [1]=>  string(2) ".." [2]=>  string(14) "1207910176.jpg" [3]=>  string(14) "1207942539.jpg" [4]=>  string(14) "1207943063.jpg" [5]=>  string(14) "1207944104.jpg" [6]=>  string(8) "logo.png" [7]=>  string(10) "screen.jpg" [8]=>  string(13) "sss-games.jpg" [9]=>  string(29) "title-summer-slots-series.jpg" }


                if(ftp_pwd($conn1)) {
                foreach($dir1 as $file1) {
				//loop through it
                if (ftp_size($conn1, $file)!==-1){
				//if its not a directory and the file exists
				$hash = md5_file($remote_dir1."/".$file1);
                $d[$hash] = $file1;
												 }
										}
								
}

MD5 was not working well with FTP so i  read the files then storeded the file names to a cache file for comparison. Worked like a charm!

  // Retrieve File List
  $files = ftp_nlist($conn, $remote_dir);

  $currentFiles = array();
  if(file_exists($cache_file))
