Use Dynamsoft Barcode Reader to Build a Barcode Scanner in PHP on WIndows


Dynamsoft's Barcode Reader SDK Windows Edition provides four APIs: C/C++, ActiveX/COM, .NET and PHP. With Dynamsoft's Barcode Reader PHP wrapper, you can easily simulate a barcode scanner in your PHP web applications.

Before providing more details, you may try the barcode PHP wrapper here. It supports reading barcodes from images (PNG, TIFF, JPEG, BMP and more) and PDF files.

Enable COM support in PHP

From PHP 5.4.5, COM and DOTNET is no longer built into the PHP core.

You have to add COM support by inserting this line in php.ini: extension = php_com_dotnet.dll

Otherwise you will see an error in your error log: Fatal error: Class 'COM' not found

Code Snippet

You can either download the source code here or follow the steps below to code from scratch.

Step 1.

Suppose you are creating a project in a folder called test. In the folder, create a test.php file and a readbarcode.php file. Also, copy the aforementioned dynamsoftbarcodereader.php file from the SDK package to the test folder.

Edit the test.php as follows:

  <head />
        <h1>Dynamsoft Barcode Reader PHP Simple Sample</h1>
        <form action="readbarcode.php" method="post" enctype="multipart/form-data">
            Select barcode image:
            <input type="file" name="barcodefile" id="barcodefile" accept="image/*" /><br/>
            <input type="submit" value="Read Barcode" name="submit"/>

Step 2.

Then edit the readbarcode.php file.Please update with valid values in the code, respectively. The licenses can be found in the [INSTALL FOLDER]\LicenseManager.exe.

include "dynamsoftbarcodereader.php";

$uploadfile = $_FILES["barcodefile"]["tmp_name"];

$br = new BarcodeReader();
$br->initLicense("<your license key here>");

$cnt = $br->getBarcodesCount();
echo "Barcode Count: $cnt <br />";
for ($i = 0; $i < $cnt; $i++) {
      $res = $br->getBarcodeResult($i);
      echo "$i. $res->BarcodeFormatString , $res->BarcodeText<br />";
