Uploading Image To A Php Page

[Adele]

Hi everybody. I want to upload a image file to a php page. I tried base64 method but I had problem. Then I wanted to try WinHTTP method but there is problem again. The codes are below. What is the problem? Or is there a different method to upload image without using form and IE? I researched a lot of topics here but I couldn't find a working a thing. Thank you in advance.
 
AutoIt Codes:

#include <ScreenCapture.au3>
$sScreenShotFile = @TempDir & "\ScreenShot.png"
$hScreenShot = _ScreenCapture_Capture($sScreenShotFile)

$hfile = FileOpen($sScreenShotFile, 16)
$sData = FileRead($hfile)

$oRequest = ObjCreate('WinHttp.WinHttpRequest.5.1')
$oRequest.Open('POST', 'http://site.com/index.php', 0)
$oRequest.SetRequestHeader('Content-Type', 'application/x-www-form-urlencoded')
$oRequest.Send('screenshot=' & $sData)

PHP Codes:

<?php

if(isset($_POST['screenshot']) && !empty($_POST['screenshot'])){
    $file = fopen(dirname(__FILE__) . "/screenshot.png", "w+b");
    fwrite($file, pack("H*" ,$_POST['screenshot'])); 
    fclose($file);
}

?>

The problem is that; the image uploads but their contents aren't same. I guess there is a problem on binary coding.

No, I'm using now with upper codes binary method. I've tried base64 method but I had problem. Sorry for my English .

You could look at trancexx's WinHTTP UDF. It's pretty awesome.

I've tried and unfortunately the result is the same.

 

I open the file being binary with this code:

$hfile = FileOpen($sScreenShotFile, 16)

After send the binary information, then I try to convert taken binary codes to string and save to a file on php.

$file = fopen(dirname(__FILE__) . "/screenshot.png", "w+b");
    fwrite($file, pack("H*" ,$_POST['screenshot']));

The codes run and are created but there is a problem. The file isn't transmitted correctly.

I remember I ran into an issue with base64 when I had done something very similar, I believe it was the equal signs but can't remember (been a couple of years).  I think I did base64+StringToHex to pass it.
