16.3　通过电子邮件发送表单数据

如果不想为服务器端脚本操心，并且能够处理未经格式化（或未经脚本预处理）的数据，可以选择通过电子邮件发送访问者的数据，如图16.3.1～图16.3.4所示。

...
<body>
 
<?php
//这是一个非常简单的PHP脚本……
if (empty($_POST)) {
    print "<p>No data was submitted.</
p>";
    print "</body></html>";
    exit();
}
 
function clear_user_input($value) {
    if (get_magic_quotes_gpc()) $value=stripslashes($value);
    $value= str_replace( "\n", '', trim($value));
    $value= str_replace( "\r", '', $value);
    return $value;
    }
 
$body ="Here is the data that was submitted:\n";
 
foreach ($_POST as $key => $value) {
    $key = clear_user_input($key);
    $value = clear_user_input($value);
    if ($key=='extras') {
 
    if (is_array($_POST['extras']) ){
       $body .= "$key: ";
       $counter =1;
       foreach ($_POST['extras'] as $value) {
             //除了最后一个元素，都应该添加逗号
             和空格
             if (sizeof($_POST['extras']) == $counter) {
                $body .= "$value\n";
                break;}
             else {
                $body .= "$value, ";
                $counter += 1;
                }
             }
       } else {
       $body .= "$key: $value\n";
       }
    } else {
 
    $body .= "$key: $value\n";
    }
}
 
extract($_POST);
$email = clear_user_input($email);
$first_name = clear_user_input ($first_name);
 
$from='From: '. $email . "(" . $first_name . ")" . "\r\n" . 'Bcc: yourmail@yourdomain.com' . "\r\n";
 
$subject = 'New Profile from Web Site';
 
mail ('yourmail@yourdomain.com',
$subject, $body, $from);
?>
