關(guān)鍵詞內(nèi)鏈開(kāi)啟步驟

• 后臺(tái)-系統(tǒng)-核心設(shè)置-關(guān)鍵字替換  【是】
• 后臺(tái)-系統(tǒng)-其他選項(xiàng)-關(guān)鍵詞替換次數(shù)  【1】或者【0】
  

關(guān)鍵詞長(zhǎng)短優(yōu)先級(jí)問(wèn)題

比如有“長(zhǎng)詞”、“我是大長(zhǎng)詞”、“我是小長(zhǎng)詞”，同時(shí)在一篇文章中出現(xiàn)，程序會(huì)優(yōu)先使用短的詞。

長(zhǎng)短優(yōu)先級(jí)問(wèn)題和PHP5.5以上問(wèn)題的解決方法

打開(kāi) /include/arc.archives.class.php 找到

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

改成

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

繼續(xù)找到

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

改成

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

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

改成

global $cfg_replace_num;
if($cfg_replace_num > 0)
{
	$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM dede_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 dede_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);
	}
}

繼續(xù)找到

//高亮專用

在它上面加入

//指定替換次數(shù)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，最終效果
