您好我在谷歌上找到此代码，并在此搜索stackoverflow。关于这个有很多帖子我已经厌倦了很多但是它没有用。我正在分享我的代码，请帮助我：

Php脚本：
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>
答案 0 :(得分：1)
首先摆脱？＆gt; ，不需要它。
$uploads_dir = "./uploads/";
$uploaded_file = $uploads_dir . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
现在应该 $ file_path 从您的代码中 $ uploads_dir 或 $ uploaded_file 我无法判断是否是错误。
