I don't believe PHP natively supports byte arrays in the same sense that .NET does. However, you could try converting each character to its ASCII representation:

<?
$file = file_get_contents($_FILES['userfile']['tmp_name']);
$byteArr = str_split($file);
foreach ($byteArr as $key=>$val) { $byteArr[$key] = ord($val); }
?>
