关于一个正则表达款的问题

Question

preg_replace("<span>*(.+?)</span>*","\\1",$str)

Answer 1

preg_match_all('/<span>(.*?)<\/span>/is',$a,$a_tmp);
$atmp=$a_tmp[0][0];
echo $atmp;

Answer 2

楼上的方法，如果碰到下面的情况
<span> <span> <span>…… </span> </span> </span>sadfklsadjf<span>sadf</span>
象这种的就不行了是吗？我测试的结果是
 <span> <span>…… </span> </span> </span>sadfklsadjf<span>sadf

Answer 3

$a = " <span>abc <span class='b'>sdasldfjl </span>asdf </span>" ;
preg_match('/\<span\>(.*)\<\/span\>/i',$a,$a_tmp); 
echo $a_tmp[1] ;

Answer 4

还是不行，
是不是正则达不到这么智能啊？
结果还不是期望的
<span> <span>…… </span> </span> </span>sadfklsadjf <span>sadf
这是完整的
<span> <span> <span>…… </span> </span> </span>sadfklsadjf <span>sadf </span>
我是想得到红色部份

Answer 5

错了，是想得到这个红色部份的
<span> <span> <span>…… </span> </span> </span>sadfklsadjf <span>sadf </span>

Answer 6

<span> <span> [color=#FF0000]<span>…… </span> </span> [/color]</span>sadfklsadjf <span>sadf </span>
