并行循环中数组之间的PHP双行线中断

Question

我被困在一个我无法解决的问题上。我想过怎么做，查了一下，结果都没有结果。

我试图在电子邮件中使用数组，我需要他们之间的双线中断。

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Im解析出这些值并将它们添加到一个变量中，以便嵌套在电子邮件中，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

我不知道如何在循环中的数组之间添加这样的中断，在循环中将数组添加到电子邮件行中。

谢谢你的帮助。

Answer 1

只需在foreach循环中添加另一个新行，如下所示：

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

在PHP中的任何时候，如果您需要换行或选项卡，只需执行以下操作

echo "\r\n";

echo "\t";

当您想要一条新的行并且希望跨平台时，也可以使用PHP_EOL。

php参考：

PHP_EOL (string)这个平台正确的“行尾”符号。自PHP 5.0.2以来即可获得
