PHP表单提交成功消息在消息后插入不需要的数字

Question

创建一个带有成功消息的php表单，该消息在成功执行任务后出现在Submit按钮下方。在php中添加一些额外的代码以创建电子邮件确认后，我现在注意到一个数字＆＃34; 1＆＃34;在我的成功消息之后插入了行 - 见下文：

关于如何使这个数字1消失的任何想法？代码如下：

<?php
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$company = $_POST['company'];
$message = $_POST['message'];
$human = $_POST['human'];
$from = 'From: Page Name'; 
$to = 'email@mysite.com';  
$subject = 'Service Inquiry';
$body = "From: $name\n E-Mail: $email\n Phone: $phone\n Company: $company\n   
Message:\n $message";

// Confirmation email.
$conf_subject = 'Your recent inquiry';

$conf_sender = 'MY SITE <no-reply@mysite.com>';

$msg =  $_POST['name'] . ",\n\nThank you for your recent inquiry. A member of 
our team will respond to your message as soon as possible.\n\nThanks,\n\nMy 
Company Team";

if ($_POST['submit']) {
   if ($name != '' && $email != '' && $phone != '' && $message != '') {
       if ($human == '4') {              
           if (mail ($to, $subject, $body, $from)) { 
           echo '<p>Thanks for your inquiry, we will get back to you as soon 
                 as we can&#33;</p>';
           echo (mail ($email, $conf_subject, $msg, 'From: ' . $conf_sender 
           ));
    } else { 
        echo '<p>Something went wrong, go back and try again&#33;</p>'; 
    } 
    } else if ($_POST['submit'] && $human != '4') {
        echo '<p>You answered the anti-spam question incorrectly&#33;</p>';
    }
    } else {
        echo '<p>You need to fill in all required fields&#33;</p>';
    }
}
?>

谢谢大家！

Answer 1

这一行：

echo (mail ($email, $conf_subject, $msg, 'From: ' . $conf_sender));

您正在回应调用邮件功能的结果。由于邮件已成功移交给服务器，因此返回true。当你回显一个布尔值true时，它会被转换为一个1的整数。这就是你在代码中看到的原因。

删除echo以删除输出中显示的1。

Answer 2

 echo (mail ($email, $conf_subject, $msg, 'From: ' . $conf_sender ));

此代码导致echo，其回显为1，因为mail（）函数返回true。我不知道为什么你在这里以任何方式回应邮件功能，只需删除回声，一切都很好。

Answer 3

这是因为这段代码：

echo (mail ($email, $conf_subject, $msg, 'From: ' . $conf_sender ));

你“回应”邮件功能的结果。邮件发送成功时“1”等于“true”。
