PHP使用Mail發送數組（）

Question

我試圖通過郵件發送數組的內容，我嘗試了print_r方法，但是不太喜歡它在電子郵件中的格式，所以我嘗試了內爆，但是目前它實際上並沒有發送內容，而是只是“陣列陣列”

這是我的代碼：

<?php 
$con = mysqli_connect("localhost", "user","pw", "db");
if (!$con)
{
 die('Could not connect: ' . mysqli_error($con));
}

$recipient_email = "email@email.com";

$result= mysqli_query($con, "SELECT * FROM subscribers WHERE datetime_registered >=       DATE_SUB(NOW(), INTERVAL 9 DAY)")or die(mysqli_error($con));
$subscribers = array();
while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)){

    $subscribers[] = array(
    "uid" => $row['id'],
    "name" => $row['name'],
    "email" => $row['email'],
    "ip" => $row['ip'],
    "date_registered" => $row['datetime_registered']
    );


 }


 $headers  = 'MIME-Version: 1.0' . "\n";
 $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\n";
 $headers .= 'From: '.$recipient_email.''."\n";

 $subject = "Subject";
 $recipient = $recipient_email;
 $content = implode("\n", $subscribers);
 mail($recipient, $subject, $content, $headers);
 ?>

有誰知道出了什么問題？

如果要使用print_r郵寄數組，請使用true填充第二個參數：

print_r($array, true);

這是因為內implode函數只會破壞您的頂級數組，即$subscribers 。 它不會下降到下一級數組數據。

你可以試試這個：

foreach($subscribers as $subscriber_data){
    $dataset[] = implode(', ', $subscriber_data);
}

$content = implode("\n", $dataset);
mail($recipient, $subject, $content, $headers);

Answer 3

在$headers變量之前，請使用以下代碼：

$newSubscribers = array();
foreach($subscribers as $data)
{
    $newSubscribers[] = implode(', ', $data);
}

$newSubscribers = implode("<br>\n", $newSubscribers);
$subscribers = $newSubscribers;

所以你的結束代碼應如下所示：

...
while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)){

$subscribers[] = array(
"uid" => $row['id'],
"name" => $row['name'],
"email" => $row['email'],
"ip" => $row['ip'],
"date_registered" => $row['datetime_registered']
);


}

$newSubscribers = array();
foreach($subscribers as $data)
{
    $newSubscribers[] = implode(', ', $data);
}

$newSubscribers = implode("\n<br>", $newSubscribers);
$subscribers = $newSubscribers;


$headers  = 'MIME-Version: 1.0' . "\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\n";
$headers .= 'From: '.$recipient_email.''."\n";

Answer 4

它不能像你想的那樣工作的原因是因為implode（）不能像你想象的那樣使用關聯數組。 我建議：

$subscribers[] = array(
"uid: {$row['id']}",
"name: {$row['name']}",
...
);

然后，當您使用implode解析此數組時，使用換行符作為分隔符，您將看到

"uid: someid
 name: somename
 ....
"

我認為這就是你想要的。 干杯!

您在鍵值對中發送該數組非常好，而不是僅發送值..

使用以下腳本轉換它並通過您的電子郵件發送。

$data = '';
foreach ($subscribers as $key=>$value){
    $data .= $key.'-------'.$value;
    $data.= "\n";
}

通過php郵件發送功能..

$headers  = 'MIME-Version: 1.0' . "\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\n";
$headers .= 'From: '.$recipient_email.''."\n";

$subject = "Subject";
$recipient = $recipient_email;
$content = $data;
mail($recipient, $subject, $content, $headers);
