带有URL的file_get_contents

Question

I am using Parse and trying to get the image from a URL and save it as a ParseFile

I was successfully able to save a locally uploaded image as a ParseFile . How can I do the same with an image URL?

echo $_POST['imageURL']; // url to image
// successfully saves uploaded image
// $file = ParseFile::createFromData( file_get_contents( $_FILES['image']['tmp_name'] ), $_FILES['image']['name']  );

// trying to save image from URL
$file = ParseFile::createFromData( file_get_contents( $_POST['imageURL'] ), $_FILES['image']['name']  );

$file->save();

This is the error I got:

Try this function

function get_url_content($URL){
          $ch = curl_init();
          curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
          curl_setopt($ch, CURLOPT_URL, $URL);
          $data = curl_exec($ch);
          curl_close($ch);
          return $data;
      }

$file =  get_url_content('http://example.com/logo.jpg');
