求助一下一个正则表达式
需要匹配的字符串为:bbabbbbabc11
我想匹配到后面的abc11
用a(.+?)11的话, 会匹配到abbbbabc11

因为a和11中的字符不确定长度, 只想匹配最后的, 请问用一个正则的话, 有什么好办法。 
------解决思路----------------------

var str="bbabbbbabc11";<br /><br />var reg=/a[^a]*11/;<br /><br />alert(reg.exec(str));
Copy after login

------解决思路----------------------
$s = 'bbabbbbabc11';<br />$p = '/a[^a]+11/';<br />preg_match($p, $s, $m);<br />print_r($m);
Copy after login
Array<br />(<br />    [0] => abc11<br />)<br /><br />
Copy after login
