            /*
---Description -
The Super Global Variable $_FILES is used in PHP 4.x.x. 
$_FILES['upload']['size'] ==> Get the Size of the File in Bytes. 
$_FILES['upload']['tmp_name'] ==> Returns the Temporary Name of the File. 
$_FILES['upload']['name'] ==> Returns the Actual Name of the File. 
$_FILES['upload']['type'] ==> Returns the Type of the File. 
So if I uploaded the file 'test.doc', the $_FILES['upload']['name'] 
would be 'phptut.doc' and $_FILES['upload']['type'] would be 'application/msword'.
