问题描述

我有一个表单字段.在该字段中，用户可以输入 EMAIL 或 MOBILE .从PHP页面中我获得了价值.之后，我要检查这是电子邮件ID还是手机号码.假设email表示我想通过电子邮件发送成功，假设mobile表示我想显示移动成功，我认为我们必须编写正则表达式，但是我不知道如何为该问题编写正则表达式?

I have one form field. In that field it's possible for user to enter EMAIL or MOBILE. From a PHP page i got value. After that i want to check whether this is email id or mobile number. suppose email means i want to email success,suppose mobile means i want to show mobile success ,i think we have to write regular expression,but i don't know how to write regular expression for this problem?

 <form action="#" method="POST" id="forgotForm">
  <div class="form-group has-feedback">
    <input type="text" class="form-control" placeholder="Email OR Mobile" id="email" name="email" value="" aria-required="true" required="" data-msg-required="Please enter your email">
    <span class="glyphicon glyphicon-envelope form-control-feedback"></span>
  </div>
  </form>

  home.php
  <?php
  $email=$_POST['email'];//here value it will come like 9986128658 or [e-mail]
  
  ?>

推荐答案

您可以使用preg_match

$email=$_POST['email'];

$emailPattern = '/^\w{2,}@\w{2,}\.\w{2,4}$/'; 
$mobilePattern ="/^[7-9][0-9]{9}$/"; 

if(preg_match($emailPattern, $email)){
    echo "Email Success!";
} else if(preg_match($mobilePattern, $email)){
    echo "Mobile Success!";
} else {
    echo "Invalid entry";
}

1. 检查有效的电子邮件

1. Checks for the valid email

• 电子邮件中应至少包含两个词的长度，例如[e-mail]
• TLD至少应包含2个字符，最多4个字符
• 要包含诸如co.in之类的域，请使用-/^\w{2,}@[\w\.]{2,}\.\w{2,4}$/

• Email should have atleast two words length say [e-mail]
• TLD should have atleast 2 characters and maximum of 4 characters
• To include domains like co.in, use - /^\w{2,}@[\w\.]{2,}\.\w{2,4}$/

检查有效的手机

• 移动设备应具有10个字符的长度，并且应以7或8或9开头，要删除该限制，请将$mobilePattern更改为/^[0-9]{10}$/

• Mobile should have 10 characters length and should start either with 7 or 8 or 9, to remove that restriction, change the $mobilePattern to /^[0-9]{10}$/
