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 58pic_keywords WHERE rpurl<>'' ORDER BY rank DESC";
改成
$query = "SELECT char_length(keyword) AS num,aid,keyword,rpurl,rank FROM 58pic_keywords WHERE rpurl<>'' ORDER BY num DESC";
继续找到
"#".preg_quote($word)."#"
改成
"#(?<!>)(?!<)".preg_quote($word)."#"
完成
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);
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>", $body);
}
}
继续找到
在它上面加入
function str_replace_limit($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
