smartReadFile

For reading media files through a PHP controller, while accepting range rquests.

This satisfies the requirements for HTML5 media requests in <audio> and <video> elements.

Code example:

This code is in the api.php file. You should refer to the api.php file for the latest version of usage example.

/* * API Example */// Perform some form of security validation.// EG., You could check their PHP session is logged in.$granted = true; // Bypass validation.if (!$granted) {
header ("HTTP/1.1 404 Not Found");
die();
}
// Get filename passed via URL$filename = $_GET['f'];
// Usually this would be hidden above the web server root. EG., '/hidden/media/'$base = 'media/';
// Whitelist filename characters. Edit if your filenames require other characters.// Never include the '/' character.// ie., Learn from the link below, if you think it is already in there, because it's not!// http://php.net/manual/en/reference.pcre.pattern.syntax.php$ok = preg_match('/^[-A-Za-z0-9_.]+$/', $filename);
// Ignore requests that smell funnyif (!$ok) {
header ("HTTP/1.1 404 Not Found");
die();
}
$file = explode('.', $filename);
// You could check they have rights to access the media here.// - No checking in this example.// Get the type by file extensionswitch ($file[count($file)-1]) {
case'mp3':
$type = 'audio/mpeg';
break;
case'ogg':
$type = 'audio/ogg';
break;
case'oga':
$type = 'audio/ogg';
break;
case'm4a':
$type = 'audio/mp4';
break;
case'm4v':
$type = 'video/mp4';
break;
case'mp4':
$type = 'video/mp4';
break;
case'webm':
$type = 'video/webm';
break;
case'ogv':
$type = 'video/ogg';
break;
}
$path = $base . $filename;
// Include and call smartReadFilerequire_once('smartReadFile.php');
smartReadFile($path, $filename, $type);
