這是源程序里邊的一部分，為了容易看懂，刪減了一大部分，只取<span style="font-family: Arial, Helvetica, sans-serif;"><div class="tideTable"> div塊中的內(nèi)容</span>

<span style="font-family: Arial, Helvetica, sans-serif;">首頁先用file_get_content或curl獲取內(nèi)容部分，我用的是curl。</span>

<span style="font-family: Arial, Helvetica, sans-serif;"><span style="white-space:pre"></span><span style="white-space:pre">		</span>$ch = curl_init();<span style="white-space:pre">		</span>curl_setopt($ch, CURLOPT_URL, $url);<span style="white-space:pre">		</span>curl_setopt($ch, CURLOPT_POST, 1);<span style="white-space:pre">		</span>curl_setopt( $ch, CURLOPT_HEADER, 0 );<span style="white-space:pre">		</span>curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );<span style="white-space:pre">		</span>curl_setopt( $ch, CURLOPT_POSTFIELDS, $data );<span style="white-space:pre">		</span>$return = curl_exec( $ch );<span style="white-space:pre">		</span>curl_close( $ch );<span style="white-space:pre">		</span><span style="white-space:pre">		</span>$regex4="/<div class=\"tideTable\".*?>.*?<\/div>/ism";<span style="white-space:pre">		</span>if(preg_match_all($regex4, $return, $matches)){            <span style="white-space:pre">		</span> print_r($matches);<span style="white-space:pre">		</span>}else{<span style="white-space:pre">			</span>echo '0';<span style="white-space:pre">		</span>}</span>

<span style="font-family:Arial, Helvetica, sans-serif;">這樣就可以了，不多解釋，懂PHP的看代碼，打印看一下效果。</span>
