php正则抓取整个域名下的图片

来源:转载

代码出处:jUnion

适用平台:Windows, Linux(Ubuntu),php-5.2.5+,Apache

功能:抓取整个站点的图片,暂无借助php的curl插件开发, 后期完善


配置:config目录下

     domain_name:域名(默认:bizhibar.com)

     request_site:网站网址(默认:http://www.bizhibar.com/)

     request_url:从网站的哪个页面开始(默认:http://www.bizhibar.com/)

     accept_type: 图片类型(默认:gif, bmp, png, ico,  jpg, jpeg)

     save_path:图片保存路径(默认:savefiles/)

     partition_name:图片保存目录名称前缀(默认:img_)

     dir_file_limit: 每个目录容许多少个文件(默认:100)

     serialize_img_size: 当读取了多少个图片地址才缓存到cache目录下的accompImg文件当中,下次继续抓取的时候会忽略这些地址。(默认:30)

     serialize_url_size:与serialize_url_size一样,已读取多少个链接地址才缓存到cache目录

下的overURL,下次继续抓取的时候忽略这些地址。(默认:10)


说明:欢迎诸君批评指教,有任何新问题或者需要改进的地方,请您反馈给我
