An HTML form contains this form element:
<input type="file" name="myFile" />
When this form is submitted, the following PHP code gets executed:
<?php
 move_uploaded_file(
 $_FILES['myFile']['tmp_name'],
 'uploads/' $_FILES['myFile']['name']);
?>
Which of the following actions must be taken before this code may go into production? (Choose 2)
                                
A.Check with is_uploaded_file() whether the uploaded file $_FILES['myFile']['tmp_name'] is valid
B.Sanitize the file name in $_FILES['myFile']['name'] because this value is not consistent among web
browsers
C.Check the charset encoding of the HTTP request to see whether it matches the encoding of the
uploaded file
D.Sanitize the file name in $_FILES['myFile']['name'] because this value could be forged
E.Use $HTTP_POST_FILES instead of $_FILES to maintain upwards compatibility
