Creating a Simple File Uploader Using PHP - Part 4

In this series of tutorials we will look at how to develop a simple file uploader using PHP. All of the code is freely available for download (License: GNU GPL) from this link: Download File Uploader.

In this tutorial, we will look at how to set the permissions on a folder/directory to enable the file to be stored.

In order to allow an uploaded file to be stored in a folder, you need to firstly change the permissions to allow the file to be stored, and then change the permissions back to 755. Here is some code that can be used to change the permissions on a folder.

      // Change the permissions on a directory to enable a file to
      // be moved into that directory
     
      $mod = '0777'; // permissions to be set

      // connect to FTP site
      $conn = ftp_connect("$host");
      if (!$conn)
      {
      echo 'Error: Could not connect to ftp server<br>';
      exit;
      }

      // log in to FTP site
      @ $result = ftp_login($conn, $username, $password);
      if (!$result)
      {
      echo "Error: Could not log on as $user<br>";
      ftp_quit($conn);
      exit;
      }

      // try to chmod the directory
      if (ftp_site($conn, 'CHMOD '.$mod.' '.$folder)) {
      // echo "Successfully changed persmissions to 0777\n";
      }
      else {
      echo "There was a problem changing the permissions to 0777\n";
      ftp_quit($conn);
      exit;
      }

      // close the connection
      ftp_close($conn);
