Hi,

I have a script to read the files in a folder & if a pdf is found, it will then call the ocr api to scan the pdf files. my script is a below. The problem I am having is that it will stop after scanning one document. The loop does not go on to the next file. Hope someone can advice where did I go wrong.

    <?php

    $dir = "/xampp/htdocs/ocr/ocrfiles/";
    $dh  = opendir($dir);
    while (false !== ($filenamedir = readdir($dh))) {
        $files[] = $filenamedir;
    }

    sort($files);

    echo "<pre>";
    print_r($files);
    echo "</pre>";

    $starter = 0;
    $arraySize = count($files);

     while ($starter < $arraySize) {
        $verifyDate = $files[$starter];
        echo $starter . ": " . $verifyDate . "<BR>";
        $ext = pathinfo($verifyDate, PATHINFO_EXTENSION);

        if ($ext == "pdf") {
            echo "run abbyy api here <BR>";

      // 1. Send image to Cloud OCR SDK using processImage call
      // 2. Get response as xml
      // 3. Read taskId from xml

      // !!!!!!!!!! Enter your data here !!!!!!!!!!
      $applicationId = 'API_ID';
      $password = 'API_PASSWORD';
      $fileName = $verifyDate;

      // Get path to file that we are going to recognize
      $local_directory=dirname(__FILE__).'/ocrfiles';
      $filePath = $local_directory.'/'.$fileName;
      if(!file_exists($filePath))
      {
        die('File '.$filePath.' not found.');
      }

      // Recognizing with English language to rtf
      // You can use combination of languages like ?language=english,russian or
      // ?language=english,french,dutch
      // For details, see API reference for processImage method
      $url = 'http://cloud.ocrsdk.com/processImage?language=english&exportFormat=xml';

      // Send HTTP POST request and ret xml response
      $curlHandle = curl_init();

      curl_setopt($curlHandle, CURLOPT_POST, 1);
      $post_array = array(
          "my_file"=>"@".$filePath,
      );
      curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $post_array); 
      $response = curl_exec($curlHandle);
      if($response == FALSE) {
        $errorText = curl_error($curlHandle);
        curl_close($curlHandle);
        die($errorText);
      }
      curl_close($curlHandle);

      // Parse xml response
      $xml = simplexml_load_string($response);
      $arr = $xml->task[0]->attributes();

      // Task id
      $taskid = $arr["id"];

      // 4. Get task information in a loop until task processing finishes
      // 5. If response contains "Completed" staus - extract url with result
      // 6. Download recognition result (text) and display it

      $url = 'http://cloud.ocrsdk.com/getTaskStatus';
      $qry_str = "?taskid=$taskid";

      // Check task status in a loop until it is finished
      // TODO: support states indicating error

      // Warning! This is for easier out-of-the box usage of the sample only.
      // The URL to the result has https:// prefix, so SSL is required to
      // download from it. For whatever reason PHP runtime fails to perform
      // a request unless SSL certificate verification is off.
      curl_setopt($curlHandle, CURLOPT_SSL_VERIFYPEER, false);
      $response = curl_exec($curlHandle);
      curl_close($curlHandle);

      // Let user donwload rtf result
      echo $response . "<BR><BR>";

    //document $ amount checker process ends
        }
        $starter++;

    }

    ?>

Hope someone can help out soon. Thanks!
