$cws->send_text($text);

echo "Top words stats:\n\n";<br /> $ret = array();<br /> $ret = $cws->get_tops(10,'r,v,p');<br /> <br /> echo "No.\tWord\t\tAttr\tTimes\tRank\n------------------------------------------------------\n";<br /> $i = 1;<br /> foreach ($ret as $tmp)<br /> {<br /> printf("%02d.\t%-16s\t%s\t%d\t%.2f\n", $i++, $tmp['word'], $tmp['attr'], $tmp['times'], $tmp['weight']);<br /> }<br /> $cws->close();<br /> </pre><pre class="brush: text">Top words stats:<br /> <br /> No. Word Attr Times Rank<br /> ------------------------------------------------------<br /> 01. 文档 n 1 4.80<br /> 02. 标题 n 1 4.76<br /> 03. 测试 vn 1 4.72</pre><br /> </div> <div class=""> <ul class="m-news-opt fix"> <li class="opt-item"> <a href='/PHPjiqiao-120708.html' target='_blank'><p>< 上一篇</p><p class="ellipsis">:mysql_fetch_row():suppliedargumentisnotavalidMySQLresultresource</p></a> </li> <li class="opt-item ta-r"> <a href='/PHPjiqiao-120710.html' target='_blank'><p>下一篇 ></p><p class="ellipsis">递归二分查找望大姐帮忙求解释</p></a> </li> </ul> </div> </div> </div> <div class="g-title fix"> <h2 class="title-txt">人气教程排行</h2> </div> <div class="m-rank u-dashed mb40"> <ul> <li class="rank-item"> <a href="/PHPjiqiao-379253.html" title='php如何获取跳转前的url' class="item-name ellipsis" target="_blank"> <span class="g-art-count fr">174次</span> <span class="g-sort-num top">1</span> php如何获取跳转前的url </a> </li> <li class="rank-item"> <a href="/PHPjiqiao-379019.html" title='php格林威治时间转换成当前时间的方法' class="item-name ellipsis" target="_blank"> <span class="g-art-count fr">174次</span> <span class="g-sort-num second">2</span> php格林威治时间转换成当前时间的方法 </a> </li> <li class="rank-item"> <a href="/PHPjiqiao-366629.html" title='为什么php不能做大型系统?' class="item-name ellipsis" target="_blank"> <span class="g-art-count fr">174次</span> <span class="g-sort-num third">3</span> 为什么php不能做大型系统?
