Validating empty $_FILES

I have a simple register form where the user can upload a profile picture, if the user doesn't it, it should take the default picture name called person-icon.png.

When I register an user and upload a picture it works but if i leave it blank don't do anything and that column is inserted into the DB empty

if(isset($_FILES['image'])){
  $img = $_FILES['image']['name'];
}
else if(empty($_FILES['image']['name'])){
  $img = 'person-icon.png';
}

I already have tried these options:

Option 1:

if (empty($_FILES['image'])){
  $img = 'person-icon.png';
}
else{
  $img = $_FILES['image']['name'];
}

Option 2:

if($_FILES["image"]["error"] == 4)

Option 3:

if($_FILES["image"]["name"] == "")

You could check for $_FILE['image']['name'] not equal "" this work; See code:

<!DOCTYPE html>
<html>
<body>

<form action="upload.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="image" id="image">
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html> 
<?php

//var_dump($_FILES);
$default_pic =" pic.png";
if (isset($_FILES['image'])){
    if($_FILES['image']['name'] != ""){
        echo "has pic";
    }
    else{
        $_FILES['image']['name'] = $default_pic;
        echo "has no pic";
    }

}
?>
