我有这个代码！
$to = "xyz@gmail.com";
$subject = "Order Confirmation - Your Order with Mysite.com[] has been successfully placed!";
$from = " abc@gmail.com.com";
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers = "From: $from\nMIME-Version: 1.0\nContent-Type: text/html; charset=utf-8\n";
$message = '<html><body>';
$message .= '<h1 style="color:#f40;">Hi Jane !</h1>';
$message .= '<table>';
$message .= '<tr>';
$message .= '<th>Order Detail</th>';
$message .= '<th>Delivery Address</th>';
$message .= '</tr>';
$message .= '<tr>';
$message .= '<td>Order successfully placed.We are pleased to confirm your order no OD111288994161211000.Thank you for shopping with Mywebsite!</td>';
$message .= '<td>xyz</td>';
$message .= '</tr></table>';
$message .= '</body></html>';
mail($to,$subject,$message,$headers);
它不发送邮件。语法是否有任何问题。
