Handling file Inputs in PHP with CURL

Last Updated at : January 30, 2018 By - Usama Muneer | 1978

    Handling files while working with APIs are always a pain. While working with API calls, the most common solution is cURL for sure for requesting & receiving data through the valid endpoints.

          $file      = Input::file( 'file_name' );
          $imagePath = $file->getPathName();
          $tmp = tempnam( sys_get_temp_dir(), 'php' );
          file_put_contents( $tmp, file_get_contents( $imagePath ) );
          $curl = curl_init();
          curl_setopt( $curl, CURLOPT_URL, 'mydomain.com/api/endpoint' );
          curl_setopt( $curl, CURLOPT_VERBOSE, 1 );
          curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, 1 );
          // sending file
          curl_setopt( $curl, CURLOPT_POST, true );
          curl_setopt( $curl,
             CURLOPT_HTTPHEADER, array(
                "authorization: Bearer " . $token
             ) );
                'file_name' => $tmp,
             ) );
          // outputting the response
          curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
          $result = curl_exec( $curl );
          unlink( $tmp ); // removing temp file
          curl_close( $curl );
          $results = json_decode( $result );


    The above piece of code is tested & works just fine. You just need to replace your image name, API endpoint & token (if required).
