我想在此PHP代码上设置我自己的附件大小限制。我已经尝试了很多代码，但是什么都没用。
您能帮我吗？我在那里应该使用什么工作代码？我想将最大大小设置为2MB，并且应该有消息“很抱歉，此附件太大（或其他问题-用于检查其是否正常工作”）。]
以及如何确定要附加的类型？例如，我只希望上传PNG和JPG。如何在我的代码上执行此操作？并且也应该有消息，例如-,,对不起，您只能附加PNG和JPG文件。“
注意！一切正常。我只想更改上传大小并制作PNG和JPG文件:)谢谢！
这是我的PHP代码：
<?php
iconv_set_encoding("internal_encoding", "UTF-8");
$headers .= 'Content-type: text/html; charset=utf-8' . "\r\n";
if(!empty($_POST["send"])) {
require_once ('phpmailer/class.phpmailer.php');
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = TRUE;
$mail->Port = 587;
$mail->Username = "[email protected]";
$mail->Password = "XXXXXXXXX";
$mail->Mailer = "smtp";
if (isset($_POST["userEmail"])) {
$userEmail = $_POST["userEmail"];
}
if (isset($_POST["userName"])) {
$userName = $_POST["userName"];
}
if (isset($_POST["subject"])) {
$subject = $_POST["subject"];
}
if (isset($_POST["userMessage"])) {
$message = $_POST["userMessage"];
}
if (isset($_POST["NickCheatera"])) {
$NickCheatera = $_POST["NickCheatera"];
}
$mail->SetFrom('[email protected]', $userName);
$mail->AddReplyTo($userEmail, $userName);
$mail->AddAddress("[email protected]"); // set recipient email address
$mail->Subject = 'Zgloszenie';
$mail->Body = join('', array(
'Wiadomosc od: ',
$_POST['userName'],

$_POST['NickCheatera'],
'<br/>',

$_POST['subject'],
'<br/>',
'Dodatkowe informacje: ',

));
$mail->WordWrap = 80;
$mail->IsHTML(true);
$mail->SMTPSecure = 'tls';
$mail->Host = 'serwer2092488.home.pl';
if (! empty($_FILES['attachment'])) {
$count = count($_FILES['attachment']['name']);
if ($count > 0) {
// Attaching multiple files with the email
for ($i = 0; $i < $count; $i ++) {
if (! empty($_FILES["attachment"]["name"])) {
$tempFileName = $_FILES["attachment"]["tmp_name"][$i];
$fileName = $_FILES["attachment"]["name"][$i];
$mail->AddAttachment($tempFileName, $fileName);
}
}
}
}
if (! $mail->Send()) {
$message = "Wystąpił problem podczas wysyłania e-maila. Spróbuj ponownie.";
$type = "error";
} else {
$message = "Dziękujemy za zgłoszenie! Odpowiemy do 24 godzin.";

尝试通过更改php.ini中的upload_max_filesize。
