java - Android Uploading Camera Image, Video to php Server -

i trying capture image or record video using camera , upload server. on server side, used php language read file , moved particular location.

this php script

<?php     // path move uploaded files  $target_path = "uploads/";     // array final json respone  $response = array();     // getting server ip address  $server_ip = gethostbyname(gethostname());     // final file url being uploaded  $file_upload_url = 'http://' . $server_ip . '/' . 'androidfileupload' . '/' . $target_path;        if (isset($_files['image']['name'])) {      $target_path = $target_path . basename($_files['image']['name']);         // reading other post parameters      $email = isset($_post['email']) ? $_post['email'] : '';      $website = isset($_post['website']) ? $_post['website'] : '';         $response['file_name'] = basename($_files['image']['name']);      $response['email'] = $email;      $response['website'] = $website;         try {          // throws exception incase file not being moved          if (!move_uploaded_file($_files['image']['tmp_name'], $target_path)) {              // make error flag true              $response['error'] = true;              $response['message'] = 'could not move file!';          }             // file uploaded          $response['message'] = 'file uploaded successfully!';          $response['error'] = false;          $response['file_path'] = $file_upload_url . basename($_files['image']['name']);      } catch (exception $e) {          // exception occurred. make error flag true          $response['error'] = true;          $response['message'] = $e->getmessage();      }  } else {      // file parameter missing      $response['error'] = true;      $response['message'] = 'not received file!f';  }     // echo final json response client  echo json_encode($response);  ?>

and got php error

i not have experience in php coding, want know what's wrong php.

the android client complete run, can take photo , video well, upload completed, got nothing in server client folder.

there android code:

i'm newbie @ stuff appreciated. much! , upload more details if needed.

gethostname() function of php >= 5.3.0 , believe server have php < 5.3.0 instead of gethostname() use php_uname('n') or update php version.
