PHP 文件上传

   先来写一下HTML上传文件的代码：

　　

<form enctype="multipart/form-data" action="upload.php" method="POST">
    <!--文件的最大限制 -->
    <input type="hidden" name="MAX_FILE_SIZE" value="30000" />
    Send this file: <input name="upfile" type="file" />
    <input type="submit" value="Send File" />
</form>

多次运行发现代码错误：

　　

<?php

$uploaddir = "/uploaded/";
$uploadfile = $uploaddir.basename($_FILES['upfile']['name']);
echo $uploadfile;
if(move_uploaded_file($_FILES['upfile']['tmp_name'],$uploadfile)){
    echo "File is valid, and was successfully uploaded.\n";
}else{
    echo "error";
}
?>

没有这个文件或路径？

好吧 修改代码：

　　

<?php
//这里没有了前面的 "/"
$uploaddir = "uploaded/";
$uploadfile = $uploaddir.basename($_FILES['upfile']['name']);
echo $uploadfile;
if(move_uploaded_file($_FILES['upfile']['tmp_name'],$uploadfile)){
    echo "File is valid, and was successfully uploaded.\n";
}else{
    echo "error";
}
?>

好了 实现上传了.
