问题描述
我正在编写一个PHP应用程序，向人们询问黎巴嫩的电话号码.我不想在输入格式上非常严格，因此我在验证时遇到了一些麻烦.
i am writing a php app that asks people for their phone number in lebanon. I don't want to be very strict in the entry format so i'm running into some trouble validating.
黎巴嫩的电话号码看起来像这样.
A lebanese phone number looks like that.
961 3 123456
961 3 123456
961 :国家/地区代码.我希望有或没有它都有效.
961: the country code. i want it to be valid with or without it.
3 :区号.这是棘手的地方.可能的区号是03、70和71.如果存在国家/地区代码，则03丢弃0并变成3，而使用国家/地区代码的70和71保持不变.
3: the area code. here's where it is tricky. the possible area codes are 03, 70 and 71. when the country code is present, 03 drops the 0 and becomes 3 while 70 and 71 are as is with or without country code.
123456 :电话号码，始终为6位数字.
123456: the phone number, always 6 digits.
以下是我要验证的格式:
here are the formats i'm trying to validate:
961 3 123456
961 70 123456
961 71 123456
03 123456
70 123456
71 123456
961 3 123456
961 70 123456
961 71 123456
03 123456
70 123456
71 123456
这里的空格只是为了清楚起见，我在删除所有空格和非字母数字字符后进行验证.
the spaces are here just for the sake of clarity, i am validating after stripping all spaces and non alphanumeric characters.
就是这样，如果有人可以提供帮助，那就太好了.谢谢
that's it, would be great if someone can help.thanks
推荐答案
我确定有一种轻松的方法，但是
I'm sure there's a slicker way to do it, but
^(961(3|70|71)|(03|70|71))\d{6}$
在我理解要求的前提下，似乎可以正常工作.
seems to work, assuming I understand the requirements.
