根据权重获取关键字 去掉文章中的超链接简单,简洁

1.根据权重获取关键字

代码如下:
function getkey($contents){
$rows = strip_tags($contents);
$arr = array(' ',' ',"\s", "\r\n", "\n", "\r", "\t", ">", "“", "”");
$qc_rows = str_replace($arr, '', $rows);
if(strlen($qc_rows)>2400){
$qc_rows = substr($qc_rows, '0', '2400');
}
$data = @implode('', file("http://keyword.discuz.com/related_kw.html?title=$contents&ics=gbk&ocs=gbk"));
preg_match_all("/(.*)A\[(.*)\]\](.*)>/",$data, $out, PREG_SET_ORDER);
for($i=0;$i$key=$key.$out[$i][2];
if($out[$i][2])$key=$key.",";
}
return $key;
}
//$contents为你要得到关键字的文章


2.去掉文章中的超链接简单,简洁

代码如下:
function get_new_content($content){
include("../simple_html_dom.php");
$html = str_get_html($content);
$a_href = $html->find('a');
foreach($a_href as $link){
$text = $link->plaintext;//链接中的文字;
$link->outertext = $text;
}
$now_content = $html->save();
}
//preg_replace("/(.*?)/i","\${1}", $content); 这样用正则也可以
