//来自uct php微信开发框架，其中的checkString函数如下
function checkString($var,$check = '',$default = '') {

else {
return $default;
}

}

}

echo checkNatInt('学好PHP拿百万年薪'); //句子中的数字,1000000
echo checkNatInt('今年春运发送人次达26亿'); //数字和汉字混合出现，2600000000

echo checkNatInt('两只小蜜蜂'); //口语化数字，2
echo checkNatInt('万万没想到'); //复古的表达方式，100000000
