我在这段代码上尝试了很多次,我知道 html 是正确的,但是 PHP 很棘手
<html>
<body>
<?php
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
$uploaddir = '/var/www/Megan/';
$uploadfile = $uploaddir . basename($_FILES['file']['name']);
move_uploaded_file($_FILES["file"]["tmp_name"],
$uploadfile);
echo "Stored in: " . "$uploaddir" . $_FILES["file"]["name"];
?>
<h1>File upload successful!</h1>
<form method="get" action="/megan">
<input type="submit" value="Continue"/>
</form>
</body>
</html>
帮我解决这个问题
