When using PHP native extensions, you have to carefully match the right PHP version. Otherwise, it may cause a compatibility issue. In addition, the web server deployment of a PHP project with customized extensions is complicated as well. A proper solution for quickly experiencing a PHP project is to use Docker. In this article, I will demonstrate how to Dockerize the PHP barcode reader project built with Dynamsoft Barcode Reader SDK for Linux.
Building Docker Image for PHP Barcode Reader
A Docker image with PHP and Apache
Create a Dockerfile and choose a suitable Docker image with PHP and Apache according to PHP Docker hub page:
FROM php:5.6-apache
Build the Docker image:
sudo docker build -t php-barcode-reader .
Run the image:
sudo docker run -p 2016:80 php-barcode-reader
Open Firefox to visit localhost:2016, you will see the Apache homepage.
A Docker image with PHP barcode reader
Since Dynamsoft Barcode Reader supports PHP 5.3, 5.4, 5.5 and 5.6 for thread-safe and non-thread-safe, you need to check the relevant information firstly.
We can access the Docker container to run Bash, referring to exec of command line reference:
sudo docker exec -it container_id bash php –v php –i | grep Thread
Download the source code of PHP barcode reader and extract the package.
Create three folders config, libs, and src, and then copy corresponding resources to these folders:
Add extension path to php.ini:
extension=/usr/lib/php_DynamsoftBarcodeReader.so
Edit Dockerfile:
FROM php:5.6-apache COPY config/php.ini /usr/local/etc/php/ COPY src/ /var/www/html/ COPY libs/ /usr/lib/
Save the Dockerfile and built the image again. Now if you run the Docker image, you will see the homepage of your PHP barcode reader:
Tag the image and push it to Docker hub:
sudo docker tag php-barcode-reader dynamsoft/php-barcode-reader sudo docker push dynamsoft/php-barcode-reader
Docker Image
https://hub.docker.com/r/dynamsoft/php-barcode-reader/
