PHP to achieve the Chinese-to-digital, the way is very smart PHP

Share an auxiliary function, using PHP to identify as many numbers as possible in the string, and achieve the following effect.

1 2 3 4 5 6 7 8 9

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

Precautions

1. Decimals not supported

2. Numbers greater than Php_int_max are not supported
