$uploadOk = 1;

// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {

echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists

echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
echo "Sorry, your file is too large.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {

$uploadOk = 0;
}

// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";

}
}
?>
Apache 日志
move_uploaded_file failed to open stream: Permission denied in /var/www/html/upload.php
第37行，referer：http://localhost/filetest.htm
我已经尝试了here 提到的所有方法，但仍然遇到问题。
这是文件夹的权限
drwxr-xr-x 2 www-data rohit 4096 Feb 24 15:58 tmp_uploads
drwxr-xr-x 2 www-data rohit 4096 Feb 24 15:05 uploads
我从
那里得到了所有者<?php echo exec('whoami'); ?>
chown user destination_dir
chmod 755 destination_dir
然后用该用户更改文件夹的所有者。
有人可以帮我解封吗？

制作这个 php: 你得到了什么？
-
@hanshenrik array(0) { } array(1) { ["submit"]=> string(12) "上传图片" } array(1) { ["fileToUpload"]=> array (5) { ["name"]=> string(9) "page1.png" ["type"]=> string(9) "image/png" ["tmp_name"]=> string(33) "/home /rohit/tmp_uploads/phpCwZA6V" ["error"]=> int(0) ["size"]=> int(205237) } }
-
@hanshenrik 但是根据 apache logs ，有一些 Permission denied 错误。其来源/分辨率是什么？
-
如果目标目录在站点文档根目录之外，您可能会遇到问题，即使 www-data 是所有者
