php正则抓取整个域名下的图片

php正则抓取整个域名下的图片

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)
