PHP邮件函数没有'；无法完成电子邮件的发送

我试着创建一个简单的邮件表单。表单本身位于我的

index.html

页面上，但它会提交到一个单独的“感谢您的提交”页面，

thankyou.php

，上面的php代码就嵌入了该页面。 代码提交得很完美，但从不发送电子邮件。如何解决此问题？

尽管此答案的某些部分仅适用于

mail（）

函数本身的使用，但这些疑难解答步骤中的许多步骤都可以应用于任何PHP邮件系统

您的脚本不发送电子邮件的原因有很多。除非有明显的语法错误，否则很难诊断这些问题。如果没有，你需要浏览下面的检查表，找出你可能遇到的任何潜在陷阱

确保已启用错误报告并设置为报告所有错误 错误报告对于根除代码中的错误和PHP遇到的一般错误至关重要。需要启用错误报告才能接收这些错误。将以下代码放在PHP文件的顶部（或主配置文件）将启用错误报告

<?php
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'From: yoursite.com';
    $to = 'contact@yoursite.com';
    $subject = 'Customer Inquiry';
    $body = "From: $name\n E-Mail: $email\n Message:\n $message";

    if ($_POST['submit']) {
        if (mail ($to, $subject, $body, $from)) {
            echo '<p>Your message has been sent!</p>';
        } else {
            echo '<p>Something went wrong, go back and try again!</p>';
        }
    }
?>

有关此操作的更多详细信息，请参阅

确保调用了

mail（）

函数 这可能看起来很愚蠢，但一个常见的错误是忘记在代码中实际放置

mail（）

函数。确保它在那里并且没有被注释掉

确保正确调用了

mail（）

函数 bool邮件（字符串$to，字符串$subject，字符串$message[，字符串$additional_headers[，字符串$additional_parameters]]））

mail函数接受三个必需的参数，还可以选择第四个和第五个参数。如果对

mail（）

的调用没有至少三个参数，则将失败

如果对

mail（）

的调用没有正确顺序的正确参数，它也将失败

检查服务器的邮件日志 您的web服务器应该记录通过它发送电子邮件的所有尝试。这些日志的位置会有所不同（您可能需要询问服务器管理员它们的位置），但它们通常可以在用户的根目录下的

日志中找到。里面将是服务器报告的错误消息，如果有的话，与您发送电子邮件的尝试有关

检查端口连接故障
端口阻塞是大多数开发人员在集成代码以使用SMTP发送电子邮件时面临的一个非常常见的问题。而且，这可以很容易地在服务器邮件日志中进行跟踪（邮件日志的服务器位置可能因服务器而异，如上所述）。如果您在共享主机服务器上，端口25和587在默认情况下保持阻塞状态。此阻止是由您的主机提供商故意执行的。即使对于某些专用服务器也是如此。当这些端口被阻止时，请尝试使用端口2525进行连接。如果您发现该端口也被阻止，那么唯一的解决方案是联系您的主机提供商以取消阻止这些端口

大多数托管提供商都会阻止这些电子邮件端口，以保护其网络不发送任何垃圾邮件

端口25或587用于普通/TLS连接，端口465用于SSL连接。对于大多数用户，建议使用端口587以避免某些主机提供商设置的速率限制

不要使用错误抑制操作符
当在PHP中的表达式前面加上
@
时，将忽略该表达式可能生成的任何错误消息。在某些情况下，需要使用此操作员，但发送邮件不是其中之一

如果您的代码包含
@mail（…）
，那么您可能隐藏了重要的错误消息，这将有助于您调试此错误。删除
@
并查看是否报告了任何错误

只有当你事后纠正具体的错误时，这才是明智的

检查
mail（）
返回值
职能：

$name = $_POST['name'];
$email = $_POST['email'];
$reciver = '/* Reciver Email address */';
if (filter_var($reciver, FILTER_VALIDATE_EMAIL)) {
    $subject = $name;
    // To send HTML mail, the Content-type header must be set.
    $headers = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
    $headers .= 'From:' . $email. "\r\n"; // Sender's Email
    //$headers .= 'Cc:' . $email. "\r\n"; // Carbon copy to Sender
    $template = '<div style="padding:50px; color:white;">Hello ,<br/>'
        . '<br/><br/>'
        . 'Name:' .$name.'<br/>'
        . 'Email:' .$email.'<br/>'
        . '<br/>'
        . '</div>';
    $sendmessage = "<div style=\"background-color:#7E7E7E; color:white;\">" . $template . "</div>";
    // Message lines should not exceed 70 characters (PHP rule), so wrap it.
    $sendmessage = wordwrap($sendmessage, 70);
    // Send mail by PHP Mail Function.
    mail($reciver, $subject, $sendmessage, $headers);
    echo "Your Query has been received, We will contact you soon.";
} else {
    echo "<span>* invalid email *</span>";
}

返回
TRUE
如果邮件已成功接受投递，则返回
FALSE
否则返回。重要的是要注意，仅仅因为邮件被接受交付，并不意味着邮件将实际到达预定目的地

这一点值得注意，因为：


如果您收到
FALSE
返回值，您知道错误在于服务器接受您的邮件。这可能不是编码问题，而是服务器配置问题。您需要与系统管理员联系以了解发生这种情况的原因
如果您收到
TRUE
返回值，并不意味着您的电子邮件一定会被发送。这仅仅意味着该电子邮件已通过PHP成功发送到服务器上相应的处理程序。在PHP的控制之外，还有更多的故障点会导致电子邮件无法发送

因此
FALSE
将帮助您找到正确的方向，而
TRUE
并不一定意味着您的电子邮件发送成功。这一点值得注意

确保您的主机提供商允许您发送电子邮件，并且不限制邮件发送
许多共享网络主机，尤其是免费网络主机提供商，要么不允许从其服务器发送电子邮件，要么限制在任何给定时间段内可以发送的邮件量。这是因为他们努力限制垃圾邮件发送者利用他们更便宜的服务

如果您认为您的主机有发送电子邮件的限制或阻止发送电子邮件，请查看他们的常见问题，看看他们是否列出了任何此类限制。否则，您可能需要联系他们的支持人员，以验证是否存在发送电子邮件的任何限制

检查垃圾邮件文件夹；防止电子邮件被标记为垃圾邮件
通常，由于各种原因，通过PHP（和其他服务器端编程语言）发送的电子邮件最终会被放在收件人的垃圾邮件文件夹中。在对代码进行故障排除之前，请始终检查该位置。
