php validate image

$image_name = $_FILES["inputname"]["name"];
$allowed_extensions = array("png", "jpg", "jpeg");
$image_extension = explode(".", $image_name);
/*
  *Explode returns array of words
  *Explode Example:
  	explode(search_for, where to search for);
    let imagine that the image named => myimage.png
    expldoe funtion will search the word for '.' and explode it
    from the example, explode will return array("myimage", "png")
    Now we find our image extension, but it is in the array.
    we use end() function that will return the last index in the array as a string
*/
$extension = end($image_extension); // which is png
if(!in_array($extension, $allowed_extensions)){
  echo "Please upload an image";
}
else{
  echo "Allowed Image";
