PHP邮件程序脚本不在电子邮件中打印变量

The issue I am having is in the message portion of the email. The email sends just fine, the outline is there but no name email or message is printed from the variable. I can't seem to see what the issue is. Any help is appreciated.

<?php session_start();
$name=$_POST['name'];
$email=$_POST['email'];
$text=$_POST['text'];
$to= 'noreply@noreply.com';
$subject = 'Request';
$message='Hello, my name is:' . $name . "
" . 'My Email is: ' . $email . "
" . 'My Message is: '. $text;
$headers = 'From: Request' . "
" .
    'Reply-To: noreply@noreply.com' . "
" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
echo 'Mail Sent';
?>

From the comment you are passing the data as query string not as payload in the POST. SO change

$name=$_POST['name'];
$email=$_POST['email'];
$text=$_POST['text'];

to

$name=$_GET['name'];
$email=$_GET['email'];
$text=$_GET['text'];

And should work !

You sent form using GET method, data are in $_GET:

<?php 

session_start();

$name  = $_GET['name'];   // here
$email = $_GET['email'];  // here
$text  = $_GET['text'];   // here
$to    = 'noreply@noreply.com';
$subject = 'Request';
$message='Hello, my name is:' . $name . "
" . 'My Email is: ' . $email . "
" . 'My Message is: '. $text;
$headers = 'From: Request' . "
" .
    'Reply-To: noreply@noreply.com' . "
" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
echo 'Mail Sent';
?>

To use your current script version, just change method attribute in form to post, like <form method=post ...>
