Question

我坚持一个我无法解决的问题。我已经考虑了如何，查找它，并没有产生任何结果。

我试图在电子邮件中使用数组，我需要在它们之间进行双重换行。

我在mysql查询结果循环中创建两个数组，如下所示：

while($row = $result->fetch_assoc()){
        $updated_email_array['Clinic']=$row['clinic_name'];
        $updated_email_array['Email_Credits_To_Add']=$row['email_allotment'];
        $updated_email_array['SMS_Credits_To_Add']=$row['sms_allotment'];
        $updated_email_array['Email_Credits_Rolling_Over']=$row['$email_left'];
        $display_email_array[] = $updated_email_array;
}

然后我解析出值并将它们添加到变量中以嵌套在电子邮件中，如下所示：

$intouch_credit_refill_message = "Credit Refill Report\n\n";
foreach ($display_email_array as $each_member) { 
    while (list($key, $value) = each ($each_member)) { 

        $intouch_credit_refill_message .= "$key: $value\n"; 

    } 

}

最后，我在电子邮件中发送$ intouch_credit_refill_message

mail($email address,"Credit Refill Record",$intouch_credit_refill_message,"From: email@address.com");

这给了我：

Credit Refill Report

Clinic: Royal York Animal Hospital
Email_Credits_To_Add: 5000
SMS_Credits_To_Add: 500
Email_Credits_Rolling_Over: 100200
Smail_Credits_Rolling_Over: 10050
New_Email_Credit_Allotment: 105200
New_SMS_Credit_Allotment: 10550
Clinic: Jason's Test Clinic
Email_Credits_To_Add: 5000
SMS_Credits_To_Add: 500
Email_Credits_Rolling_Over: 75000
Smail_Credits_Rolling_Over: 7500
New_Email_Credit_Allotment: 80000
New_SMS_Credit_Allotment: 8000

但我需要：

Credit Refill Report

Clinic: Royal York Animal Hospital
Email_Credits_To_Add: 5000
SMS_Credits_To_Add: 500
Email_Credits_Rolling_Over: 100200
Smail_Credits_Rolling_Over: 10050
New_Email_Credit_Allotment: 105200
New_SMS_Credit_Allotment: 10550

Clinic: Jason's Test Clinic
Email_Credits_To_Add: 5000
SMS_Credits_To_Add: 500
Email_Credits_Rolling_Over: 75000
Smail_Credits_Rolling_Over: 7500
New_Email_Credit_Allotment: 80000
New_SMS_Credit_Allotment: 8000

我无法弄清楚如何在循环中的数组之间添加这样的中断，并将它们添加到电子邮件行中。

感谢您提供任何帮助。

Answer 1

只需在foreach循环中添加另一个新行：

foreach ($display_email_array as $each_member) { 
    while (list($key, $value) = each ($each_member)) { 

        $intouch_credit_refill_message .= "$key: $value\n"; 

    } 

    $intouch_credit_refill_message .= "\n";

}

Answer 2

如果您需要换行符或选项卡，那么在PHP中的任何时候都可以执行此操作

echo "\r\n";

echo "\t";

如果您想要新的广告系列，并且希望跨平台，也可以使用PHP_EOL。

php参考：

PHP_EOL（string）此平台的正确“行尾”符号。自PHP 5.0.2起可用

PHP循环中的PHP双线断开
