The effect is as follows.
echo checkNatInt('九百六十万'); //普通中文数字,9600000 echo checkNatInt('壹亿柒仟万零捌佰肆拾'); //大写中文数字,170000840 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
