正规表达试问题。取{a}{/a}之间的字符串

Question

这样的话先把{/a}REPLACE成{a},再用{a} EXPLODE快点吧

Answer 1

$str=str_replace("{/a}","{a}",$str);
$strrow=explode("{a}",$str);

Answer 2

sorry,刚看错意思了,这么写
<?php$str="asfasdfasdfasdf{a}asdfasdfsdafasdf{/a}asd{a}fasdf{/a}sadfasdfasdf";preg_match_all("|{a}[0-9a-zA-Z]*{/a}|",$str,$out);print_r($out[0]);?>

Answer 3

<% 
String s="asfasdfasdfasdf{a}asdfasdfsdafasdf{/a}asd{a}fasdf{/a}sadfasdfasdf";
String ss[] =s.split("\{\/?a\}");
for(int i=0;i<ss.length;i++)
{
out.println(ss[i]+"<br/>");
}
%>

Answer 4

不懂php,以上关键是ss[] =s.split("\{\/?a\}")其它部分翻译成php就行
