Question

我试图将MySql数据库中的多行回显到电子邮件的$ message部分。附加的代码只返回一个结果。

我想在电子邮件中发送1封电子邮件，我想从SQL查询中输出10行。实际上，我实际上会收到十次单独的电子邮件，而不是一封包含十行的电子邮件。

$sql = "SELECT * FROM stoic_quotes Order By rand() Limit 0,10";
$result = $conn->query($sql);

while($row = $result->fetch_assoc()) {
    $to      = 'email@email.com';
    $subject = 'Daily Stoic Email';
    $message = $row["Maxim"]. "</br>";
    $headers = 'From: email@email.com' . "\r\n" .
        'Reply-To: email@email.om' . "\r\n" .
        'X-Mailer: PHP/' . phpversion();

    mail($to, $subject, $message, $headers);
}

Answer 1

将邮件调用移出循环

// don't select all (*) fields if you only need one
$sql = "SELECT Maxim FROM stoic_quotes Order By rand() Limit 0,10";

$result = $conn->query($sql);

$message = '';

while($row = $result->fetch_assoc()) {
    $message .= $row["Maxim"]. "</br>";
}

// prepare email headers
$to      = 'email@email.com';
$subject = 'Daily Stoic Email';
$headers = 'From: email@email.com' . "\r\n" .
           'Reply-To: email@email.om' . "\r\n" .
           'X-Mailer: PHP/' . phpversion();

// then send
mail($to, $subject, $message, $headers);

Answer 2

我没有测试过代码，但试试看：

$to      = 'email@email.com';
$subject = 'Daily Stoic Email';

$sql = "SELECT * FROM stoic_quotes Order By rand() Limit 0,10";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()) {
$message = $row["Maxim"]. "</br>";
}
$headers = 'From: email@email.com' . "\r\n" .
    'Reply-To: email@email.om' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

我已将to，subject，header和mail功能放在循环之外。
