                  问题描述

                  我购买了联系表.很棒的小东西,但我需要转换电话号码的验证以允许英国号码格式 - 换句话说,允许空格.

                  I purchased a contact form. Great little thing but I need to convert the validation for the phone number to allow for UK number formats - in other words, to allow for spaces.

                  现在它验证时没有空格,并且至少有 8 个字符:

                  Right now it validates without spaces and has a minimum length of 8 characters:

                  if(is_numeric($phone))
                  {
                      if(!$phone || strlen($phone) < 8)
                      {
                          $error .= "Please enter your phone number without spaces.<br />";
                      }
                  }
                  else
                  {
                      $error .= "Please enter numeric characters in the phone number field.<br />";
                  }
                  

                  推荐答案

                  电话号码对于正则表达式模式来说通常很糟糕,而这正是你所需要的.

                  Phone numbers are typically horrible for regex patterns, which is what you will need.

                  以这种模式为例:

                  $pattern = "/^(+44s?7d{3}|(?07d{3})?)s?d{3}s?d{3}$/";
                  
                  $match = preg_match($pattern,$input);
                  
                  if ($match != false) {
                      // We have a valid phone number
                  } else {
                      // We have an invalid phone number
                  }
                  

                  该模式将与是否包含 +44 匹配,例如

                  That pattern will match with +44 included or not e.g.

                  所有这些都会匹配:

                  07222 555555
                  
                  (07222) 555555
                  
                  +44 7222 555 555
                  

                  这些不会

                  7222 555555
                  
                  +44 07222 555555
                  
                  (+447222) 555555
                  

                  有很多网站提供正则表达式的教程/备忘单等.尝试其中一些:

                  There are a load of sites that offer tutorials / cheat sheets etc. for regular expressions try some of these:

                  http://regexlib.com/Default.aspx

                  还有一篇非常好的栈溢出帖子:

                  as well as a very good stack overflow post:
