编辑：，我已经混合和修改了下面给出的两个答案，形成了一个完整的函数，它现在完成了我想要的，然后一些.所以我想我应该把它贴在这里以防其他人来找同样的东西。

/*
 * Function to analyze string against many popular formatting styles of phone numbers
 * Also breaks phone number into it's respective components
 * 3-digit area code, 3-digit exchange code, 4-digit subscriber number
 * After which it validates the 10 digit US number against NANPA guidelines
*/
function validPhone($phone) {

  $format_pattern = '/^(?:(?:\((?=\d{3}\)))?(\d{3})(?:(?<=\(\d{3})\))?[\s.\/-]?)?(\d{3})[\s\.\/-]?(\d{4})\s?(?:(?:(?:(?:e|x|ex|ext)\.?\:?|extension\:?)\s?)(?=\d+)(\d+))?$/';
  $nanpa_pattern = '/^(?:1)?(?(?!(37|96))[2-9][0-8][0-9](?<!(11)))?[2-9][0-9]{2}(?<!(11))[0-9]{4}(?<!(555(01([0-9][0-9])|1212)))$/';

  //Set array of variables to false initially
  $valid = array(
    'format' => false,
    'nanpa' => false,
    'ext' => false,
    'all' => false
  );

  //Check data against the format analyzer
  if(preg_match($format_pattern, $phone, $matchset)) {
    $valid['format'] = true;    
  }

  //If formatted properly, continue
  if($valid['format']) {

    //Set array of new components
    $components = array(
      'ac' => $matchset[1], //area code
      'xc' => $matchset[2], //exchange code
      'sn' => $matchset[3], //subscriber number
      'xn' => $matchset[4], //extension number
    );

    //Set array of number variants
    $numbers = array(
      'original' => $matchset[0],
      'stripped' => substr(preg_replace('[\D]', '', $matchset[0]), 0, 10)
    );

    //Now let's check the first ten digits against NANPA standards
    if(preg_match($nanpa_pattern, $numbers['stripped'])) {
      $valid['nanpa'] = true;
    }

    //If the NANPA guidelines have been met, continue
    if($valid['nanpa']) {
      if(!empty($components['xn'])) {
        if(preg_match('/^[\d]{1,6}$/', $components['xn'])) {
          $valid['ext'] = true;
        }
      }
      else {
        $valid['ext'] = true;
      }
    }

    //If the extension number is valid or non-existent, continue
    if($valid['ext']) {
      $valid['all'] = true;
    }
  }
  return $valid['all'];

您可以使用前瞻性断言来解决这个问题。基本上，我们的意思是，我想要一系列特定的字母，(e，ex，ext，x，扩展名)，后面跟着一个或多个数字。但是，我们也想讨论没有任何扩展的情况。

附带注意，您不需要在诸如\s或后面的x这样的单个字符周围加上括号。此外，您还可以分组字符，这些字符应该位于同一个位置，因此可以使用\s./?代替\s?/？意思是“其中任何一个角色”

下面是regex的更新，它也解决了您的评论。我在实际代码中添加了解释。

<?php
    $sPattern = "/^

当前REGEX

/^[\(]?(\d{0,3})[\)]?[\.]?[\/]?[\s]?[\-]?(\d{3})[\s]?[\.]?[\/]?[\-]?(\d{4})[\s]?[x]?(\d*)$/

有许多问题，因此它与以下所有内容匹配，其中包括：

(0./ -000 ./-0000 x00000000000000000000000)

()./1234567890123456789012345678901234567890

\)\-555/1212 x

我认为这个REGEX更接近你要找的东西：

/^(?:(?:(?:1[.\/\s-]?)(?!\())?(?:\((?=\d{3}\)))?((?(?!(37|96))[2-9][0-8][0-9](?<!(11)))?[2-9])(?:\((?<=\(\d{3}))?)?[.\/\s-]?([0-9]{2}(?<!(11)))[.\/\s-]?([0-9]{4}(?<!(555(01([0-9][0-9])|1212))))(?:[\s]*(?:(?:x|ext|extn|ex)[.:]*|extension[:]?)?[\s]*(\d+))?$/

或者爆炸：

?>

这种修改提供了几个改进。

它创建一组可配置的项，这些项可以作为扩展进行匹配。可以为扩展添加其他分隔符。--这是最初的请求。--扩展还允许在扩展分隔符之后设置冒号。
它将4个可选分隔符(点、空格、斜杠或连字符)的序列转换为只匹配一个字符类的字符类。
它对项目进行适当的分组。在给定的示例中，您可以在没有区号的情况下使用括号，并且可以在没有扩展的情况下使用扩展标记(空格-x)。这个备用正则表达式要么需要完整的区号，要么不需要，或者需要完整的扩展，或者不需要。
数字的4个组件(区号、中央办公代码、电话号码和分机)是输入到$matches in preg_match()中的反向引用元素。
使用查找/后置来要求区号中匹配的括号。
允许在数字之前使用1-。(这假设所有的数字都是美国或加拿大的数字，这似乎是合理的，因为比赛最终是根据NANPA的限制进行的。此外，还不允许将国家代码前缀和地区代码混合在括号内。
它合并在NANPA规则中，以消除不可分配的电话号码。
1. 它消除了表格0xx，1xx 37x，96x，x9x和x11中的区号，它们都是无效的NANPA区号。
2. 它消除了0xx和1xx (无效的NANPA中央办公代码)格式的中央办公代码。
3. 它消除了表格555-01xx (不可从NANPA分配)的数字。

它有一些小的限制。它们可能并不重要，但在这里已经被注意到了。

没有任何地方要求重复使用相同的分隔符，允许诸如800-555.1212、800 /551212800等数字。
在带括号的区号之后，没有任何地方可以限制分隔符，允许(800)-555-1212或(800)/5551212这样的数字。

NANPA规则来自以下REGEX，如下所示：http://blogchuck.com/2010/01/php-regex-for-validating-phone-numbers/

/^(?:1)?(?(?!(37|96))[2-9][0-8][0-9](?<!(11)))?[2-9][0-9]{2}(?<!(11))[0-9]{4}(?<!(555(01([0-9][0-9])|1212)))$/

为什么不把一系列的字母转换成"x“呢？这样你就可以把所有的可能性转换成"x“。

或

检查3位、3位、4位、1位或1orMoreDigits，忽略中间的任何其他字符

Regex：([0-9]{3}).*?([0-9]{3}).*?([0-9]{4}).+?([0-9]{1,})
