我在 Centos 7 专用机器上运行 xampp 5.6.8。
我开发了简单的脚本来通过机器上的 PHP 将任何文件上传到服务器，PHP 代码:
<?php
if (is_uploaded_file($_FILES['uploadfile']['tmp_name'])) {
echo "File ". $_FILES['uploadfile']['name'].'-'.$_FILES['uploadfile']["tmp_name"]." - uploaded successfully.<br>";
echo disk_free_space('/');
}
?>
<html>
<head>
<title>test</title>
</head>
<body>
<div style="text-align:center;">
<form action="" method="post" enctype="multipart/form-data">
<input name="uploadfile" type="file">
<input name="sendfile" value="upload" type="submit">
</form>
</div>
</body>
</html>
当我发送示例文件时回显返回:
File sample.txt - /opt/lampp/temp/phpD58n0L - uploaded successfully.
一些信息和事实:
- 当我打开
xampp由daemon用户运行时 /opt/lampp/temp/目录属于daemon:daemon通过chown 命令/opt/lampp/temp/设置为770权限php.ini设置为允许最大 128mb 的文件，上传目录为/opt/lampp/temp/
最佳答案
使用 is_uploaded_file() 只是检查它是否是上传的文件。它不会将它从您的/temp/目录移动到任何地方。您可能想看看 manual on POST uploads .示例:
$uploaddir = '/var/www/uploads/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
echo "File is valid, and was successfully uploaded.\n";
} else {
echo "Possible file upload attack!\n";
}
也就是说，您应该使用 move_uploaded_file() 将上传文件移动到它所属的位置。否则，手册上说，解释了为什么在/temp/目录中找不到这些文件:
The file will be deleted from the temporary directory at the end of the request if it has not been moved away or renamed.
函数is_uploaded_file()是对文件来源的安全检查，仅此而已。您可以将它与 move_uploaded_file() 一起使用，例如:
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $destination_file)) {
// Was moved
}
else {
// Wasn't moved
}
else {
// Wasn't valid
}
虽然这对于常规文件上传和移动来说可能是多余的，但我在手册的评论中注意到 move_uploaded_file() 会在任何情况下进行检查。
