过滤掉一些字符问题
91#col#投药中和#row#97#col#JiaoTiLiZi.gif#row#98#col#萃取#row#99#col#FenPeiXiShu.GIF#row#

结构是这样:id + #col# + 名字 + #row#
91#col#投药中和#row# 97#col#JiaoTiLiZi.gif#row# 

很多这样的数据,要处理掉gif

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$contents = preg_replace('/[\w]#col#(.*?).gif#row#'/i,'',$contents);
Copy after login


我想这样替换成空,这种方法是不是不太好呢?
而且这个正则有错

------解决方案--------------------
若处理的是固定的字符串可以用 str_replace()函数
------解决方案--------------------
这样?
PHP code
$str="91#col#投药中和#row#97#col#JiaoTiLiZi.gif#row#98#col#萃取#row#99#col#FenPeiXiShu.GIF#row#";$str=preg_replace('/#[\d]+#col#[a-z]+.gif#row#/is','#',$str);echo $str;<br><font color="#e78608">------解决方案--------------------</font><br>
Copy after login
PHP code
$contents = preg_replace('/(col#[^\.]+)\.gif(#row)/i','$1$2',$s);echo $contents;<br><font color="#e78608">------解决方案--------------------</font><br>
Copy after login
PHP code
$str='91#col#投药中和#row#97#col#JiaoTiLiZi.gif#row#98#col#萃取#row#99#col#FenPeiXiShu.GIF#row#';echo preg_replace('/\d*#col#[^#]*(?
                 
              
              
        
            
Copy after login
