Answer 1

There is: is_uploaded_file(). When dealing with uploaded files, you should always use it (and its cousin move_uploaded_file()) for security reasons.

Answer 2

You can try this:

if($_FILES['myfilename']['size'] > 0 ) {

}
else{
       echo 'File is not uploaded . . .';
}

Answer 3

You can use empty to check if a variable is blank or not but Pekka's solution is best in this way

if (empty($_FILES["myfilename"]["name"]))

If you are checking that if a variable is set you can use isset function

Answer 4

The best way, assuming you're using a recent PHP (4.2+), is to check that:

$_FILE['myfilename']['error'] === UPLOAD_ERR_OK

If this is true the upload worked, you can see the list of other possible values here

Answer 5

Try this:

if($_FILES["uploadImg"]['name'][0] != ''){
    //echo 'file attached';
}else{
    //echo 'no file attached';
}

This works for me...
