PHP server side, POST

[nombre]

I have this PHP code that I'm trying to get to write a file that it receives from a POST form a Java app:

<?php
// In PHP versions earlier than 4.1.0, $HTTP_POST_FILES should be used instead
// of $_FILES.

$uploaddir = '/www/';
$uploadfile = $uploaddir . basename($_FILES["fileToUpload"]["name"]);
$file_name = "image.jpg";

//move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile); 
 if ($_FILES["fileToUpload"]["error"] > 0)
    {
    echo "Apologies, an error has occurred.";
    echo "Error Code: " . $_FILES["fileToUpload"]["error"];
    }
 else
    {
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"],
      "/" . $_FILES["fileToUpload"]["name"]);
      echo "Stored in: " . "" . $_FILES["file"]["name"];
      }

$handle = fopen($file_name, "w");
        fputs($handle, $_FILES["fileToUpload"]["name"]);
        fclose($handle);





print_r($_FILES);



?>

The output says that it is saving to Array. How do I get that data from Array to file?

Here is the output from the Java side (client)
Stored in: Array
(
[IMG_1909_jpg] => Array
(
[name] => IMG_1909.jpg
[type] => application/octet-stream
[tmp_name] => C:\wamp\tmp\phpD912.tmp
[error] => 0
[size] => 123231
)

)

Could someone please help? Thanks

since the app seems to make the key for the $_FILES array based on the filename, you first need to get this key:

<?php

$fileinfo = reset ($_FILES); //get the first entry on the array
$uploaddir = "/www/";
$uploadfile = $uploaddir . $fileinfo["name"];
$file_name = "image.jpg";

if ($fileinfo["error"] > 0)
{
    echo "Apologies, an error has occurred.";
    echo "Error Code: " . $fileinfo["error"];
}
else
{
    // changed the path because the other one would put the file in the system's root dir
    move_uploaded_file($fileinfo["tmp_name"],$uploadfile);
    echo "Stored in: " . $uploadfile;
}

// what's this supposed to do? it doesn't make any sense.
/*
$handle = fopen($file_name, "w");
        fputs($handle, $_FILES["fileToUpload"]["name"]);
        fclose($handle);
*/

print_r($_FILES);

?>

Thanks I finally got it working!
