php採集問題，遇到程式碼中的多個空格和換行怎麼處理？

原始碼是：

<code><a class="figure  figure-180236 " data-qidanadd-albumid="543438400" data-qidanadd-episode="0" data-qidanadd-channelid="1" data-qidanadd-tvid="543438400" data-qidanadd-vip="0" data-widget-qidanadd="qidanadd" data-widget-block="block" data-block-type="qs1404043" data-searchpingback-elem="link" data-searchpingback-param="ptype=1-1" href="http://www.iqiyi.com/v_19rr9g9wks.html?fc=87451bff3f7d2f4a#vfrm=2-3-0-1" data-playsrc-linktype="play" data-playsrc-elem="pic" data-pb="rtgt=iqiyi&p2=9000" target="_blank"></a></code>

採集php程式碼是：

<code>preg_match("#<a class='\"figure' figure-180236 data-qidanadd-albumid='\"543438400\"' data-qidanadd-episode='\"0\"' data-qidanadd-channelid='\"1\"' data-qidanadd-tvid='\"543438400\"' data-qidanadd-vip='\"0\"' data-widget-qidanadd='\"qidanadd\"' data-widget-block='\"block\"' data-block-type='\"qs1404043\"' data-searchpingback-elem='\"link\"' data-searchpingback-param='\"ptype=1-1\"' href="%5C%22(.*?)%5C%22" data-playsrc-linktype='\"play\"' data-playsrc-elem='\"pic\"' data-pb='\"rtgt=iqiyi&p2=9000\"' target='\"_blank\"'>#",$content,$array);</a></code>

但是這樣的話採集不到資訊？求解

請好好學習PHP的正規表示式模式，其中有一個m是指多行匹配可以滿足你的需求，http://php.net/manual/en/refe...。

建議html解析使用DiDom
類似jquery的dom選擇

說到底就是想得到超連結的href連結地址對吧，你的正則寫的太多了，寫的越多越難匹配到，另外多行匹配就像樓上說的有專門的模式匹配符，我一般用的是s
