关于一个简单的正则表达式!

Question

explode(",", ...);
for()
{
   explode("#", ...);
}

Answer 1

$str = "1,AAAA#2,BBBB#3,CCCC#4,DDDD#" ;
$a = preg_replace("/(\d)(,\w+#)/","'\\1',",$str) ;
$b = preg_replace("/\d,(\w+)#/","'\\1',",$str) ;

Answer 2

多了个逗号
substr($a,0,-1) ;
substr($b,0,-1) ;

Answer 3

如果 $str 中含有中文就不行了.
$str = "1,AAAA#2,BBBB#3,CCCC#4,DDDD#" ;
比如变成
$str = "N01,主页#N02,新闻#N03,下载#";
就不行了.

Answer 4

$a = preg_replace("/([\w\d]+)(,.+?#)/","'\\1',",$str) ;
$b = preg_replace("/[\w\d]+,(.+?)#/","'\\1',",$str) ;
