我对 php 很陌生，所以请原谅我的知识不足，但我正在使用电子邮件表单让用户在我的网页上注册，但运行它时遇到错误。

完整的脚本如下：

<?php
if(isset($_POST['email'])) {

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "contact@slapmybeat.com";
    $email_subject = "New e-mail subscriber";


    function died($error) {
        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form your submitted. ";
        echo "These errors appear below.<br /><br />";
        echo $error."<br /><br />";
        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if
        (!isset($_POST['email'])) {
        died('We are sorry, but there appears to be a problem with the email your submitted.');     
    }


    $email_from = $_POST['email']; // required

    $error_message = "";
    $email_exp = "/^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/";
    if(!preg_match($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }

  if(strlen($error_message) > 0) {
    died($error_message);
  }
    $email_message = "Form details below.\n\n";

    function clean_string($string) {
      $bad = array("content-type","bcc:","to:","cc:","href");
      return str_replace($bad,"",$string);
    }


    $email_message .= "Email: ".clean_string($email_from)."\n";


// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>

<!-- include your own success html here -->

首先，由于初始脚本如下所示，我遇到了“eregi depreciated”错误：

        $error_message = "";
    $email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";
  if(!eregi($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }

谷歌搜索后，我将其替换为：

    $error_message = "";
    $email_exp = "/^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/";
    if(!preg_match($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }

但现在它给了我以下信息，尽管电子邮件地址是正确的：

非常抱歉，您提交的表单存在错误。这些错误出现在下面。

您输入的电子邮件地址似乎无效。

请返回并修复这些错误。

任何帮助将不胜感激

eregi不区分大小写，preg_match不是。

您必须添加i到模式 ( /..../i) 的末尾。

Not a direct answer, but if you want to check for a valid e-mail address, it is a lot easier to use php's built-in filters:

$email = filter_var($email_from, FILTER_VALIDATE_EMAIL);

Now $email will contain the filtered e-mail address or false if the filter failed (not a valid address in this case).

You should escape the "." inside the [] because it will match every character if you don't do it, you'll have:

"/^[A-Z0-9\._%-]+@[A-Z0-9\.-]+\.[A-Z]{2,4}$/i"
