在整个StackOverflow中,有许多代码以各种方式处理电话号码。
他们中的大多数使用美国电话号码格式。还有一些可用于某些英国号码,但并非所有号码都能产生正确的结果。
以下代码格式化英国电话号码如下:
从03,08和09开始的非地理数字格式为0xxx xxx xxxx和+44 xxx xxx xxxx。
07年开始的手机号码格式为07xxx xxxxxx和+44 7xxx xxxxxx。
VoIP和其他05号码的格式为05xxx xxxxxx和+44 5xxx xxxxxx。
从01和02开始的数字是地理数字。它们具有可变长度的区号。最新的Ofcom规范已发布在www.ofcom.org.uk/static/numbering/sabc.txt和www.ofcom.org.uk/static/numbering/codelist.zip上,以确保准确性。
Ofcom列表0113/0114/0115/0116/0117/0118和0121/0141具有3位区域代码和015242,013873,015394 / 015395 / 015396,016973 / 016974,017683 / 017684/017687和019467 as有5位区号。其余部分使用4位区号。 0171和0181曾经是伦敦的3位区号,但已不再使用。
使用包含的基于表单的简单输入,可以轻松测试PHP代码。如果代码以其他方式使用,则可以丢弃表单。
首先删除输入的任何主要国际访问代码和国家/地区代码数字。在敲除无关字符(例如空格和标点符号)以及任何干线数字(如果存在)之后,然后检查数字长度以确保其长度为10位且在有效范围内。然后使用一小组简单规则对数字进行格式化。
还包括对“ext.234”或“x 234”形式附加的分机号码的基本支持。
最终输出以国内和国际格式呈现。
该代码未考虑非标准号码0800 1111和0845 4647.这些只有7位数字不常见。
