使用PHP输出内容发送邮件不会显示在收件箱中

Question

I have Forgot Password Form where users can enter their valid email address. I have no problem in sending mail to user, my only problem is that i want to send to users their account information from database (Username & Password )so that they will know their username and password. But it seems like I'm having hard time on how to display their account information on the user's inbox. I'm new in PHP and it would be great if you could help me on how to figure it out.

Here's my code:

Edited:

<?php
if (isset($_POST['submit'])) {
    $email_from = "[e-mail]";
    $datesent = date('D m/d/Y, g:i A');
    $error_message = "";
    $msg = "";
    $subject = "Some text here";


    //some validations here

    $query = "Select * from user_information where EMAIL_ADDRESS = '".$_POST['email']."'";
    $result = mysql_query($query) or die("ERROR: ".mysql_error());
    $check = mysql_num_rows($result);
    if ($check == 0) {
        $row = mysql_fetch_assoc($result);
        $username = $row['USERNAME'];
        $password = $row['PASSWORD'];
        $fname = $row['FIRST_NAME'];
    }
    ob_start(); //Turn on output buffering
?>

    Hi <? php echo $fname; ?>!

        Here is your Account information:

        Username: <? php echo $username; ?>
        Password: <? php echo $password; ?>

    //some text here

<?php
    $message = ob_get_contents();
    ob_get_clean();
    $email_message = "From: ".clean_string($email_from)."
";
    $email_message. = "Sent: ".clean_string($datesent)."
";
    $email_message. = "Subject: ".clean_string($subject)."
";
    $email_message. = "
".clean_string($message)."
";
    $headers = 'From: '.$email_from."
";
    $headers. = 'To: '.$email."
";
    $headers. = 'Sent: '.$datesent."
";
    $email_sent = @mail($sendto, $subject, $email_message, $headers);
} ?>

Answer 1

The following code does not work fpr you:

$check = mysql_num_rows($result);
if($check==0){
    ...
 }

should be:

$check = mysql_num_rows($result);
if($check != false){
    ...
 }

You only set the username, password and fname if there is no resulting row
