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:
<html>
<head />
<body>
<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"/>
</form>
</body>
</html>
Step 2.
Then edit the readbarcode.php file.Please update <your license key here> with valid values in the code, respectively. The licenses can be found in the [INSTALL FOLDER]\LicenseManager.exe.
<?php
include "dynamsoftbarcodereader.php";
$uploadfile = $_FILES["barcodefile"]["tmp_name"];
$br = new BarcodeReader();
$br->initLicense("<your license key here>");
$br->decodeFile($uploadfile);
$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 />";
}
?>
