PHP Identification of two-dimensional code method (Php-zbarcode installation and use) _php skills

This article illustrates the method of PHP to recognize two-dimensional code. Share to everyone for your reference, specific as follows:

Description: The extension needs to rely on ImageMagick and Zbar, install the two software before installation

1. Installation of ImageMagick (http://www.imagemagick.org/)

Yum Install imagemagick.x86_64 imagemagick-devel.x86_64

2. Installation of Zbar (Http://sourceforge.net/projects/zbar/?source=directory)

wget http://jaist.dl.sourceforge.net/project/zbar/zbar/0.10/zbar-0.10.tar.bz2
tar jxvf zbar-0.10.tar.bz2
CD zbar-0.10
#注意此步有大坑, to prohibit Gtk,python and QT support, otherwise you will be waiting for an unlimited error
./configure--WITHOUT-GTK--without-python-- WITHOUT-QT--prefix=/usr/local/zbar make
&& make install
#提示如下为完成, not an error
#make [2]: Leaving Directory '/root/zbar-0.10 '
#make [1]: Leaving directory '/root/zbar-0.10 '
#echo '/usr/local/zbar/lib/' >>/etc/ld.so.conf
 ldconfig
 ln-s/usr/local/zbar/lib/pkgconfig/zbar.pc/usr/lib64/pkgconfig/ zbar.pc

3. Installation of Php-zbarcode (Https://github.com/mkoppanen/php-zbarcode)

Unzip Php-zbarcode-master.zip
cd php-zbarcode-master
/usr/local/php/bin/phpize
./configure-- With-php-config=/usr/local/php/bin/php-config make
&& make install
#提示如下完成
#Build complete.
#Don ' t forget to run ' make test '.
#Installing Shared extensions:   /usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/

4. Add: extension=zbarcode.so to php.ini configuration file

5. Test effect

In addition, the user can also use the station two-dimensional code generation tool to generate two-dimensional code pictures to test:
Http://tools.jb51.net/transcoding/jb51qrcode

The test code is as follows:

<?php
  //Create a new Image object
  $image = new Zbarcodeimage ("./test.png");
  Create a two-dimensional code recognizer
  $scanner = new Zbarcodescanner ();
  Recognition of image
  $barcode = $scanner->scan ($image);
  Circular output two-dimensional code information
  if (!empty ($barcode)) {
    foreach ($barcode as $code) {
      printf ("Found type%s barcode with data%s\ n ", $code [' type '], $code [' data ']);
    }
? >
