IF ($file_ext != "GIF" OR "JPG")
{
echo "no, you we dont allow that type of file!";
} else {
echo "yes";
}

## How do i get it so if it neither ='s the aboves.. it goes to no

How do i make it so if either = GIF or JPG ... then it works

also, how would i make it so it picked up all lowercase+uppercase ones....
i,e- if $file_ext == "jPg";

if (!in_array(strtolower($file_ext) , array('gif', 'jpg'))
{
echo "no, you we dont allow that type of file!";
} else {
echo "yes";
}
