C# and PHP Code Samples for Replacing Multiple Texts in PDF

Question

The following code sample shows how developers can replace multiple text in a PDF file in C# and PHP using Aspose.Pdf for Cloud API in their applications. Developers can use Aspose REST API with any language: .NET, Java, PHP, Ruby, Rails, Python, jQuery and many more.

 

[C# Code Sample]

 

AsposeApp.AppSID  = "77***********************************";

AsposeApp.AppKey = "9a*******************************";

 

//build URI

stringstrURI = "http://api.aspose.com/v1.1/pdf/test.pdf/replaceTextList";

 

//sign URI

stringsignedURI = Utils.Sign(strURI);

 

//build JSON to post

TextReplace textReplace1 = new TextReplace();

textReplace1.OldValue = "[!firm!]";

textReplace1.NewValue = "Aspose";

textReplace1.Regex = "false";

 

//build JSON to post

TextReplace textReplace2 = new TextReplace();

textReplace2.OldValue = "[!client!]";

textReplace2.NewValue = "Mark";

textReplace2.Regex = "false";

 

MultipleTextReplacestextReplaces = new MultipleTextReplaces();

textReplaces.TextReplaces = new TextReplace[] { textReplace1, textReplace2 };

stringstrJSON = JsonConvert.SerializeObject(textReplaces);

Console.Write(strJSON);

Utils.ProcessCommand(signedURI, "POST", strJSON);

 

//build URI

strURI = "http://api.aspose.com/v1.1/storage/file/test.pdf";

 

//sign URI

signedURI = Utils.Sign(strURI);

 

Stream responseStream = Utils.ProcessCommand(signedURI, "GET");

using (Stream fileStream = System.IO.File.OpenWrite(@"test.pdf"))

{

Utils.CopyStream(responseStream, fileStream);

}

responseStream.Close();

 

//Following are required classes

public class MultipleTextReplaces

    {

publicTextReplace[] TextReplaces { get; set; }

    }

public class TextReplace

    {

publicTextReplace() { }

 

public string OldValue { get; set; }

public string NewValue { get; set; }

public string Regex { get; set; }

 

    }

 

[PHP Code Sample]

 

use Aspose\Cloud\Common\AsposeApp;

use Aspose\Cloud\Common\Utils;

use Aspose\Cloud\Common\Product;

                                   

AsposeApp::$appSID = "77******-1***-4***-a***-80**********";

AsposeApp::$appKey = "********************************";

 

$filePath = getcwd() . "/Input/test.pdf";

$fileName = basename($filePath);

$oldText1 = "[!firm!]";

$newText1 = "Aspose";

$oldText2 = "[!client!]";

$newText2 = "Mark";

$oldText3 = "[!transaction_date!]";

$newText3 = "01-01-2014";

 

//build URI

echo "Uploading pdf file... <br/>";

$strURIRequest = "http://api.aspose.com/v1.1/storage/file/" . $fileName;

$signedURI = Utils::sign($strURIRequest);

 

echoUtils::uploadFileBinary($signedURI, $filePath);

echo "Pdf file has been uploaded successully<br/>";

 

echo "Replacing text...<br/>";

//Build JSON to post

$fieldsArray = array('TextReplaces'=>array(array('OldValue'=>$oldText1, 'NewValue'=>$newText1, 'Regex'=>'false'),

      array('OldValue'=>$oldText2, 'NewValue'=>$newText2, 'Regex'=>'false'),

      array('OldValue'=>$oldText3, 'NewValue'=>$newText3, 'Regex'=>'false')));

$json = json_encode($fieldsArray);

 

//Build URI to replace text

$strURI = "http://api.aspose.com/v1.1/pdf/" . $fileName . "/replaceTextList";

$signedURI = Utils::sign($strURI);

 

$responseStream = Utils::processCommand($signedURI, "POST", "json", $json);

 

//Save PDF file on server

//build URI

$strURI = "http://api.aspose.com/v1.1/storage/file/" . $fileName;

//sign URI

$signedURI = Utils::sign($strURI);

$responseStream = Utils::processCommand($signedURI, "GET", "", "");

$outputPath = getcwd() . "/output/" . $fileName;

Utils::saveFile($responseStream, $outputPath);

echo "The text has been replaced and Pdf file has saved at: " . $outputPath;
