This is a PHP wrapper for zbar-tools – (only zbarimg at the moment). See http://zbar.sourceforge.net/.

Requirements

  • zbar-tools – To install on Ubuntu it’s as easy as sudo apt-get install zbar-tools. See their project page for more platforms.
  • ImageMagick – It’s required by Zbar, I’m not sure if they bundle it or not so make sure you have it

Installation

Install this package through Composer.

Add this to your composer.json dependencies:

"require": {
   "robbiep/zbar-qrdecoder": "^2.0"
}

Run composer install to download the required files.

Usage

require_once('vendor/autoload.php');

$ZbarDecoder = new RobbiePZbarQrdecoderZbarDecoder();

# Optionally change the path of the zbarimg executable if you need to (default: /usr/bin)
$ZbarDecoder->setPath('/usr/local/bin');

# Decode the image
$result = $ZbarDecoder->make('/a/path/to/image_with_barcode.jpg');

echo $result; // Outputs the decoded text
echo $result->format; // Outputs the barcode's format
echo $result->code; // 200 if it decoded a barcode OR 400 if it couldn't find a barcode.

If you’re using it in Laravel…

I’ve included a ServiceProvider class and a config if you need to change any options. Yyou need to add the ServiceProvider to config/app.php

'providers' => array(
    ...
    'RobbiePZbarQrdecoderZbarQrdecoderServiceProvider'
)

You may need to publish the config php artisan vendor:publish

Now you can use Zbar QR Decoder in your Laravel application!

Usage (in Laravel)

# Decode the image
$result = ZbarDecoder::make('/a/path/to/image_with_barcode.png');

echo $result; // Outputs the decoded text
echo $result->format; // Outputs the barcode's format

Other barcodes supported

  • EAN_13 / ISBN
  • CODE_39
  • CODE_128
