PHP识别二维码的方法(php-zbarcode扩展)

源码来自github ：https://github.com/mkoppanen/php-zbarcode

1.安装ImageMagick(http://www.imagemagick.org/)

yum install ImageMagick.x86_64 ImageMagick-devel.x86_64

2.安装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，要禁止gtk,python和qt的支持，不然你就等着无限报错吧
./configure --without-gtk --without-python --without-qt --prefix=/usr/local/zbar
 
#./configure --without-gtk --disable-video --without-imagemagick --without-python --without-qt --without-gtk --without-x --prefix=/usr/local/zbar 还要禁止video


make && make install
 
#提示如下为完成，不是报错
#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.安装php-zbarcode(https://github.com/mkoppanen/php-zbarcode)

这个步骤有问题

zbarcode.c

错误一：环境为php7才可以编译但是通过phpInfo() 查看就是php7 无解

          ^
/root/php-zbarcode-master/zbarcode.c: 在函数‘s_php_zbarcode_scan_page’中:
/root/php-zbarcode-master/zbarcode.c:275:57: 错误：宏“add_assoc_string”传递了 4 个参数，但只需要 3 个
   add_assoc_string(symbol_array, "data", (char *)data, 1);

错误二

  zend_object_value retval;
  ^
/root/php-zbarcode-master/zbarcode.c:660:8: 错误：在非结构或联合中请求成员‘handle’
  retval.handle = zend_objects_store_put(intern, NULL, (zend_objects_free_object_storage_t) php_zbarcode_object_free_storage, NULL TSRMLS_CC);
        ^

                                                        ^
/root/php-zbarcode-master/zbarcode.c:660:92: 错误：expected ‘)’ before ‘php_zbarcode_object_free_storage’
  retval.handle = zend_objects_store_put(intern, NULL, (zend_objects_free_object_storage_t) php_zbarcode_object_free_storage, NULL TSRMLS_CC);

等等...

wget https://github.com/mkoppanen/php-zbarcode/archive/master.zip

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.添加：extension=zbarcode.so 到php.ini配置文件

此时查看phpinfo();后搜索zbarcode后为完成

5.测试效果

/* Create new image object */
$image = new ZBarCodeImage("test.jpg");

/* Create a barcode scanner */
$scanner = new ZBarCodeScanner();

/* Scan the image */
$barcode = $scanner->scan($image);

/* Loop through possible barcodes */
if (!empty($barcode)) {
    foreach ($barcode as $code) {
        printf("Found type %s barcode with data %s\n", $code[\'type\'], $code[\'data\']);
    }
