比如同時有兩個關(guān)鍵詞， dedecms 和 　dedecms模板　　這里，如果出現(xiàn)dedecms模板，他就會給 dedecms加上個鏈接，然后 dedecms模板又套一個鏈接，造成頁面HTML標簽不對稱，對SEO很不友好。。

下面給出解決方法。。。

找到function ReplaceKeyword($kw,&$body)這行，從這行開始一直替換到文件結(jié)束。這段代碼我親自測試過，可以解決，網(wǎng)上有很多這樣的，我都一個個的測試過，都不行，有的可能是文件中的符號有問題。

function ReplaceKeyword($kw,&$body)
{
global $cfg_cmspath;
$maxkey = 5;
$kws = explode(",",trim($kw)); //以分好為間隔符
$i=0;
$karr = $kaarr = $GLOBALS['replaced'] = array();


//暫時屏蔽超鏈接
$body = preg_replace("/(<a(.*))(>)(.*)(<)(/a>)/isU", '\1-]-\4-[-\6', $body);


global $dsql;
$query="SELECT * FROM dede_keywords WHERE rpurl<>'' and sta=1 ORDER BY length(keyword)desc";
$dsql->SetQuery($query);
$dsql->Execute();
while($row = $dsql->GetArray())
{
$key = trim($row['keyword']);
$key_url=trim($row['rpurl']);
$karr[] = $key;
$kaarr[] = "<u><a href='$key_url' target='_blank' title='$key'>$key</a></u>";
}
foreach ($karr as $key => $word)
{


$body = preg_replace("/(^|>)([^<]+)(?=<|$)/sUe", "_highlight('\2', $karr[$key], $kaarr[$key], '\1')", $body);
//echo $body."<br/>";


//恢復超鏈接
$body = preg_replace("/(<a(.*))-]-(.*)-[-(/a>)/isU", '\1>\3<\4', $body);
//暫時屏蔽超鏈接
$body = preg_replace("/(<a(.*))(>)(.*)(<)(/a>)/isU", '\1-]-\4-[-\6', $body);


}


//恢復超鏈接
$body = preg_replace("/(<a(.*))-]-(.*)-[-(/a>)/isU", '\1>\3<\4', $body);
return $body;
}


}//End Archives


//高亮專用, 替換多次是可能不能達到最多次
function _highlight($string, $words, $result, $pre)
{
global $cfg_replace_num;
$string = str_replace('&;', '"', $string);


if($GLOBALS['replaced'][$words] == 1)
{
return $pre.$string;
}


if($cfg_replace_num > 0)
{
$string = preg_replace("/".preg_quote($words)."/", $result, $string, $cfg_replace_num);
if(strpos($string, $words) !== false)
{
$GLOBALS['replaced'][$words] = 1;
//echo $words;
}


}
else
{
$string = str_replace($words, $result, $string);
}


return $pre.$string;
}
