PHP upload file, create a recursive directory instance code _php instance

Copy Code code as follows:

<?php

$uid =$_request[' uid '];

$avatar = ' d:/avic/discuz/uc_server/data/avatar/'. Get_avatar ($uid, $size, $type);
$dir =dirname ($avatar);

//Create directory After success move temporary file

if ($_files["pic"] ["error"] >= 0) {
if (move_uploaded_file $_files [' Pic ']　　　　[' Tmp_name '], $avatar)) {
$errorcode =1;
　　　　　　}else{
$errorcode =0;
$errormsg = "File move Failed";　　　　
}
}else{
$errorcode =0;
$errormsg =$_files[' pic '] [' ERROR '];
}

$back =array ("ErrorCode" => $errorcode, ' errormsg ' => $errormsg);
echo Json_encode ($back);

//Returns the path to be stored by the picture

return $dir 1. ' /'. $dir 2. ' /'. $dir 3. ' /'. substr ($uid,-2). $typeadd. " _avatar_$size.jpg ";
}
///recursively create a directory, if the $dir is not an absolute path, then the directory that runs this method
