รบกวนสอบถามการ copy file ระหว่าง Domain A ไปยัง Domain B ครับ

<?php
if(isset($_REQUEST['get_list'])){
     $filelist = glob( 'path/*.*'); echo json_encode( $filelist);
}elseif( isset($_REQUEST['get_content'])){
     echo file_get_content( $_REQUEST['get_content']);
}
?>

         $file = 'http://www.abcdefg.com/image.jpg';
			$file_headers = @get_headers($file);
			if($file_headers[0] == 'HTTP/1.1 404 Not Found') {
				$img = 'images/no_image.jpg';
			}
			else {
				$url_arr = explode ('/', $file);
				$ct = count($url_arr);
				$name = $url_arr[$ct-1];
				$name_div = explode('.', $name);
				$ct_dot = count($name_div);
				$img_type = $name_div[$ct_dot -1];

				$destinationPath = 'image.jpg';
				file_put_contents($destinationPath, file_get_contents($file));
			}
