墨鱼今天想把帝国CMS栏目副标题里的下划线改成横线,栏目实在太多了,就想着写个脚本处理吧,代码片段如下:
$query="select * from phome_enewsclass where bname like '%_%' order by classid desc";
发现始终无法匹配到正确的数据,查阅了一下百度相关MYSQL特殊符号数据查询说明,发现下划线的表达为like '%_%' 就是前面用斜杠转义下,果然就可以了!
完整PHP代码如下:放到/e/extend/文件访问,文件名随意。
<?php define('EmpireCMSAdmin','1'); require("../class/connect.php"); require("../class/db_sql.php"); require("../class/functions.php"); require("../class/t_functions.php"); require("../data/dbcache/class.php"); require("../data/language/gb/pub/fun.php"); $link=db_connect(); $empire=new mysqlquery(); $editor=1; $username=''; $query="select * from phome_enewsclass where bname like '%_%' order by classid desc"; $sql=$empire->query($query); while($r=$empire->fetch($sql)) { $new_bname=str_replace('_',' - ',$r[bname]); echo ''.$r[classid].'--'.$r[bname].'--'.$new_bname.'<br>'; $empire->query("update phome_enewsclass set bname='$new_bname' where classid='$r[classid]'"); } db_close(); $empire=null; ?>
