织梦关键词自动内链、php5.5以上失效问题解决方法

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。

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

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

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
