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。

解决关键词长短优先级问题的方法

打开 /include/arc.archives.class.php 找到

$query = "SELECT * FROM #@__keywords WHERE rpurl<>'' ORDER BY rank DESC";1

改成

$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM #@__keywords WHERE rpurl<>'' ORDER BY num DESC";1

继续找到

"#".preg_quote($word)."#"1

改成

"#(?<!>)(?!<)".preg_quote($word)."#"1

完成

最终效果

PHP版本高于5.5无法使用关键词內链的解决方法

打开 /include/arc.archives.class.php 找到

$body = @preg_replace_callback("#(^|>)([^<]+)(?=<|$)#sU", "_highlight('\\2', \$karr, \$kaarr, '\\1')", $body);1

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, "<a href='$key_url' target='_blank'><u>$key</u></a>", $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, "<a href='$key_url' target='_blank'><u>$key</u></a>", $body); 	}
