请问PHP用正则表达式,下面这种情况?
一个项目中可能出现以下两种情况,

第一种:
........SADFA:

    123

SLDKJLSKDFJ.........

第二种:
........SADFA:
                                               0

SLDKJLSKDFJ.........

请问大侠们,有没有办法用一个正则表达式就表示了啊?
我想的:
preg_match("/SADFA:.*?(\d+)/is",$text,$reg);
这样结果就拿到javascript:void(0)里面这个0了,
改成下面的:
preg_match("/SADFA:.*?([1-9]\d*)/is",$text,$reg);
可以拿到红色部分的数字,但是红色部分是0的话,我就没办法了,求帮忙。。。
