Question

我有以下问题。我喜欢在邮件正文中有一些行，最多10行。我从数据库中获得的行。我怎么能这样做？我的代码在这里。通过回声，我得到了＆＃34;线＆＃34;但我怎么能把它放在变量中，我喜欢在我的邮件消息体中使用？

mysql_query("SET NAMES 'utf8'");
                        $sql = "SELECT * FROM multi_booking WHERE booking_no = '{$_GET['booking']}'";             
                        $ergebnis_sub = mysql_query($sql);

                        while ($row_sub = mysql_fetch_object($ergebnis_sub))
                                    {
                                        mysql_query("SET NAMES 'utf8'");
                                        $sql1 = "SELECT * FROM multi_orders WHERE booking_no = '{$_GET['booking']}'";
                                        $result = mysql_query($sql1);
                                        $row_count = mysql_num_rows($result);
                                        for($i = 1; $i <= $row_count; $i++) 
                                        { 
                                            $row = mysql_fetch_array($result); 
                                            echo("Service[$i]. {$row['Services']}\n");
                                        }

                                        $idbooking  = $row_sub->idbooking;
                                        $name  = $row_sub->name;
                                        $email  = $row_sub->email;
                                        $blang  = $row_sub->lang;
                                        $country  = $row_sub->country;
                                        $arrivaldate  = $row_sub->arrivaldate;
                                        $accommodation  = $row_sub->accommodation;
                                        $totalamount  = $row_sub->totalamount;
                                        $invoice  = $row_sub->invoice;
                                        $comment = $row_sub->comment;

                                        $message2 = "

您可以使用.运算符连接字符串，这样就可以将它们组合成一个变量。

$lines = "";
for($i = 1; $i <= $row_count; $i++) 
{ 
  $row = mysql_fetch_array($result); 
  $lines = $lines . "Service[$i]. {$row['Services']}\n");
}

然后，您可以将这些行与消息组合在一起，就像使用其他变量一样。

$message2 = "
Subject: Booking $invoice<br />
-----------------------------------------------------------------------------------------------------------<br />
Name: $name<br />
EMail: $email<br />
Language: $blang<br />
Country: $country<br />
Arrival Date: $arrivaldate<br />
$lines
Total amount: $totalamount<br />
Booking Invoice: $invoice<br />
Booking Comment: $comment<br />";

您也可以使用简写.=，就像使用+=向变量添加内容一样。下面两行是相同的：

$mystring = $mystring . 'x';
$mystring .= 'x';

邮件消息中的数组和变量
