PHP程序错误：Warning: move_uploaded_file: failed to open stream:

Posted 2023-03-26

我写的一段文件上传程序,是php的程序如下：<?php
$uploaddir = '/form/upload/file/';
$uploadfile = $uploaddir. $_FILES['userfile'] ['name'];
print "<pre>";
if (move_uploaded_file($_FILES['userfile'] ['tmp_name'], $uploadfile))
print "上传成功！下面是调试信息：\n";
print_r($_FILES);
else
print "上传失败，以下是调试信息：\n";
print_r($_FILES);

print "</pre>";

?>
结果出现如下错误，怎么解决？

Warning: move_uploaded_file(/form/upload/file/IPMSG.exe): failed to open stream: No such file or directory in f:\我的学习\it\php\web\form\upload\upload-2.php on line 13

Warning: move_uploaded_file(): Unable to move 'D:\DOCUME~1\alexzhao\LOCALS~1\Temp\php96.tmp' to '/form/upload/file/IPMSG.exe' in f:\我的学习\it\php\web\form\upload\upload-2.php on line 13
很感谢楼下的两位的回答，可是我试过了，还是不行。
第三位朋友的答案我也试过了，不行啊！！！！！！

参考技术A $uploaddir = '/form/upload/file/';

改成

$uploaddir = './form/upload/file/';
$uploaddir = '../form/upload/file/';

试试。本回答被提问者采纳 参考技术B 应该是权限的问题，修改上传目录的权限。就可以了。 参考技术C 用绝对路径
