trying to access a file using http://
does not look valid to me, probably you want something like one of these:
$a = storage_path('ElephantsDream.mp4');
$a = public_path('ElephantsDream.mp4');
$a = asset('ElephantsDream.mp4');
depending on where the file is physically in your laravel directory.
@carcinocron thanks so external url not supported right ?
Is there a way to do this same process but with AJAX?
Here is my code. For sure require to check URL and File. Just assume file path / URL is correct.
// Check starting string
if (substr($this->path, 0, 3) == 'htt' || substr($this->path, 0, 3) == 'ftp') { /* External URL - allow_url_fopen=On /
$headers = get_headers($this->path, 1);
$this->size = $headers["Content-Length"];
}else{ / Internal file */
$this->size = filesize($this->path);
}
:
//fseek($this->stream, $this->start);
header('HTTP/1.1 206 Partial Content');
header("Content-Length: ".$length);
header("Content-Range: bytes $this->start-$this->end/".$this->size);
// Use stream_get_contents instead of fseek
echo stream_get_contents($this->stream, -1, $this->start);
