Convert php script to Javascript

[Guvera]

Hi friends,

I am familiar in Asp.net. I have a php script code for flash uploading. I need to convert this php script to java script. For ur's reference i put the code below,

<?php
include("JSON.php");
$result = array();

if (isset($_FILES['photoupload']) )
{
$file = $_FILES['photoupload']['tmp_name'];
$error = false;
$size = false;

if (!is_uploaded_file($file) || ($_FILES['photoupload']['size'] > 2 * 1024 * 1024) )
{
$error = 'Please upload only files smaller than 2Mb!';
}
elseif (!$error && !($size = @getimagesize($file) ) )
{
$error = 'Please upload only images, no other files are supported.';
}
elseif (!$error && !in_array($size[2], array(1, 2, 3, 7, 8) ) )
{
$error = 'Please upload only images of type JPEG.';
}
elseif (!$error && ($size[0] < 25) || ($size[1] < 25))
{
$error = 'Please upload an image bigger than 25px.';
}
else {
move_uploaded_file($_FILES['photoupload']['tmp_name'], "./uploadedfiles/".$_FILES['photoupload']['name']);
chmod("./uploadedfiles/".$_FILES['photoupload']['name'], 0777);
}

$addr = gethostbyaddr($_SERVER['REMOTE_ADDR']);

$log = fopen('script.log', 'a');
fputs($log, ($error ? 'FAILED' : 'SUCCESS') . ' - ' . preg_replace('/^[^.]+/', '***', $addr) . ": {$_FILES['photoupload']['name']} - {$_FILES['photoupload']['size']} byte\n" );
fclose($log);

if ($error)
{
$result['result'] = 'failed';
$result['error'] = $error;
}
else
{
$result['result'] = 'success';
$result['size'] = "Uploaded an image ({$size['mime']}) with {$size[0]}px/{$size[1]}px.";
}

}
else
{
$result['result'] = 'error';
$result['error'] = 'Missing file or internal error!';
}

if (!headers_sent() )
{
header('Content-type: application/json');
}

echo json_encode($result);

?>

In the above code a temporary file created and the uploaded files are stored in that folder.I need to convert this code in javascript.

I hope ur's reply

Thanks

You mean you need to convert it to ASP.NET? Because you can't really do a file upload with a client side scripting language like JavaScript.
