PHP Barcode Reader

The sample demonstrates how to make a Web Barcode Reader app with PHP, Nginx and Dynamsoft Barcode Reader SDK on Windows.

Prerequisites

• Nginx
• PHP
• Dynamsoft Barcode Reader SDK

How to Build PHP Custom Extension with Dynamsoft Barcode Reader SDK

Please read Making PHP Barcode Extension with Dynamsoft Barcode SDK to learn how to build php_dbr.dll.

How to Configure PHP Environment

1. Copy php_dbr.dll to %php%\ext.

2. Copy DynamsoftBarcodeReaderx86.dll to PHP root directory **%php%**.

3. Open %php%\php.ini and add following line:

   extension=php_dbr.dll
   

   Change max file size if you want to upload big image files:

   upload_max_filesize=20M
   

How to Configure Nginx for PHP

1. Open %nginx%\conf\nginx.conf and add PHP configuration:

   location ~ \.php$ {
       root           html;
       fastcgi_pass   127.0.0.1:9000;
       fastcgi_index  index.php;
       fastcgi_param  SCRIPT_FILENAME <Your Web App Folder>/$fastcgi_script_name;
       include        fastcgi_params;
   }
   

   When uploading big files, you may see the error nginx 413 Request Entity Too Large. To fix it, change file size in configuration file:

   client_max_body_size 50M;
   

How to Run the PHP Barcode App

1. Run php-cgi:

   %php%\php-cgi.exe -b 127.0.0.1:9000 -c %php%\php.ini
   

2. Run Nginx:

   %nginx%\nginx.exe
   

3. Visit localhost:8080/index.php
