关键词长短优先级问题

比如有“长词”、“我是大长词”、“我是小长词”，同时在一篇文章中出现，程序会优先使用短的词。

长短优先级问题和PHP5.5以上问题的解决方法

打开 /include/arc.archives.class.php 找到

$query = "SELECT * FROM keywords WHERE rpurl<>'' ORDER BY rank DESC";

改成

$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM keywords WHERE rpurl<>'' ORDER BY num DESC";

继续找到

"#".preg_quote($word)."#"

改成

"#".preg_quote($word, "#")."(?!

继续找到

$body = @preg_replace_callback("#(^|>)([^

改成

global $cfg_replace_num;

if($cfg_replace_num > 0)

{

$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM keywords WHERE rpurl<>'' ORDER BY num DESC";

$this->dsql->SetQuery($query);

$this->dsql->Execute();

while($row = $this->dsql->GetArray())

{

$key = trim($row['keyword']);

$key_url=trim($row['rpurl']);

$body = str_replace_limit($key, "$key", $body, $cfg_replace_num);

}

}

else

{

$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM keywords WHERE rpurl<>'' ORDER BY num DESC";

$this->dsql->SetQuery($query);

$this->dsql->Execute();

while($row = $this->dsql->GetArray())

{

$key = trim($row['keyword']);

$key_url=trim($row['rpurl']);

$body = str_replace($key, "$key", $body);

}

}

继续找到

//高亮专用

在它上面加入

//指定替换次数功能

function str_replace_limit($search, $replace, $subject, $limit)

{

if(is_array($search))

{

foreach($search as $k=>$v)

{

$search[$k] = "#".preg_quote($search[$k], "#")."(?!

}

}

else

{

$search = "#".preg_quote($search, "#")."(?!

}

return preg_replace($search, $replace, $subject, $limit);

}

完成，最终效果
