  PHP版本高于5.5无法使用关键词內链的解决方法

  打开 /clude/arc.archives.class.php 找到

  $body = @preg_replace_callback("#(^|>)([^<]+)(?=<|$)#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 58pic_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 58pic_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);
  	}
  }

  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);
  }
