后阵列的嵌入式阵列

Question

所以这可能很简单，但我似乎可以让它在我的最终工作。我目前有一个看起来像这样的嵌入式数组：

$array = array (
    array(
        $_SESSION['Contact']['Name'],
        $_SESSION['Contact']['Email']
        ...
    )
);

我的会话数组中有大约 30 个字段。使用上面的示例，我必须手动列出每个会话数组项。所以，我的问题是，有没有办法遍历 Sessions 数组以获得与上述相同的结果。

$array = array (
    array(
       foreach ($_SESSION as $key => $value){
         $value.", ";
       }
    )
); 

//我的电子邮件/CSV 功能

function create_csv_string($data) {

  // Open temp file pointer
  if (!$fp = fopen('php://temp', 'w+')) return FALSE;

  // Loop data and write to file pointer
  foreach ($data as $line) fputcsv($fp, $line);

  // Place stream pointer at beginning
  rewind($fp);

  // Return the data
  return stream_get_contents($fp);

}

function send_csv_mail ($csvData, $body, $to = 'xx@xxx.com', $subject = 'Test email with attachment', $from = 'zz@zzz.com') {

  // This will provide plenty adequate entropy
  $multipartSep = '-----'.md5(time()).'-----';

  // Arrays are much more readable
  $headers = array(
    "From: $from",
    "Reply-To: $from",
      "Content-Type: multipart/mixed; boundary=\"$multipartSep\""
  );

    // Make the attachment
    $attachment = chunk_split(base64_encode(create_csv_string($csvData)));

    // Make the body of the message
    $body = "--$multipartSep\r\n"
        . "Content-Type: text/plain; charset=ISO-8859-1; format=flowed\r\n"
        . "Content-Transfer-Encoding: 7bit\r\n"
        . "\r\n"
        . "$body\r\n"
        . "--$multipartSep\r\n"
        . "Content-Type: text/csv\r\n"
        . "Content-Transfer-Encoding: base64\r\n"
        . "Content-Disposition: attachment; filename=\"file.csv\"\r\n"
        . "\r\n"
        . "$attachment\r\n"
        . "--$multipartSep--";

    // Send the email, return the result
    return @mail($to, $subject, $body, implode("\r\n", $headers));

}

send_csv_mail($array, "Hello World!!!\r\n This is simple text email message.");

Answer 1

嗯，我想通了。简单的答案，几乎太明显了。

$array = array (
        $_SESSION['Purchase']
);
