【PHP】 php正则抓取整个域名下的图片
作者:jUnion / 发布于2013/9/13/ 740

	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）

	

	index.php入口程序

	<?php
	set_time_limit(0);

	'site' => __Home__.'config'.__Os__.'capture.site.php',
	'preg' => __Home__.'config'.__Os__.'capture.preg.php',
	'accompImg' => __Home__.'cache'.__Os__.'accompImg',
	'overURL' => __Home__.'cache'.__Os__.'overURL'
	);

	$_parse = new Capture( $_cfg );
	$_parse->parseQuestUrl();
