$url_head = get_headers($url)


if($url_head == FALSE) 
{
         echo "URL or HEAD Unavailable.....";
}


else
{
         // now check url image hav not 404 error to download...
         $head_chk = strpos ($url_head[0], '404 Not Found');


 if($head_chk === FALSE) 
 {

       $image_data = file_get_contents($url);   // get content from url..
       $image_name = basename($url);   // for save same name which in url.
       $image__save_location = "/path/images_folder";   // Save location or path..
        
       if(!$image_data)
       {
         // write some another image url like default image save if not available....
         $no_image_data = "some default image url... if some image not available on url"


         // now save image using file_put_contents function with same name which in url.
         file_put_contents($image__save_location."/".$image_name,  $no_image_data);
      }
       else
       {
          file_put_contents($image__save_location."/".$image_name,  $image_data);

1. getimagesize($url);
2. get_headers($url);
3. file_get_contents($url);
