         [type] => image/jpeg
         [tmp_name] => C:\Windows\Temp\phpFF07.tmp

Method 1:

<?php
print_r($_FILES);

$filename=$_FILES[&#39;img&#39;][&#39;name&#39;];
$type=$_FILES[&#39;img&#39;][&#39;type&#39;];
$tmp_name=$_FILES[&#39;img&#39;][&#39;tmp_name&#39;];
$size=$_FILES[&#39;img&#39;][&#39;size&#39;];
$error=$_FILES[&#39;img&#39;][&#39;error&#39;];

//将服务器上的临时文件移动到指定目录下
move_uploaded_file($tmp_name, "img/".$filename);

Copy after login

$_FILES is the file upload variable, which stores the file upload data

move_uploaded_file($tmp_name,"specified folder name".$filename);

Move the temporary files on the server to the specified directory, return true if successful, false if failed
