EXAMPLES
Example #1
stream_notification_callback(3) example
<?php
function stream_notification_callback($notification_code, $severity, $message, $message_code, $bytes_transferred, $bytes_max) {
switch($notification_code) {
case STREAM_NOTIFY_RESOLVE:
case STREAM_NOTIFY_AUTH_REQUIRED:
case STREAM_NOTIFY_COMPLETED:
case STREAM_NOTIFY_FAILURE:
case STREAM_NOTIFY_AUTH_RESULT:
var_dump($notification_code, $severity, $message, $message_code, $bytes_transferred, $bytes_max);
/* Ignore */
break;
case STREAM_NOTIFY_REDIRECTED:
echo "Being redirected to: ", $message;
break;
case STREAM_NOTIFY_CONNECT:
echo "Connected...";
break;
case STREAM_NOTIFY_FILE_SIZE_IS:
echo "Got the filesize: ", $bytes_max;
break;
case STREAM_NOTIFY_MIME_TYPE_IS:
echo "Found the mime-type: ", $message;
break;
case STREAM_NOTIFY_PROGRESS:
echo "Made some progress, downloaded ", $bytes_transferred, " so far";
break;
}
echo "

}
$ctx = stream_context_create();
stream_context_set_params($ctx, array("notification" => "stream_notification_callback"));
file_get_contents("http://php.net/contact", false, $ctx);
?>
The above example will output something similar to:

case STREAM_NOTIFY_FILE_SIZE_IS:
$filesize = $bytes_max;
echo "Filesize: ", $filesize, "

break;
case STREAM_NOTIFY_MIME_TYPE_IS:
echo "Mime-type: ", $message, "

break;
case STREAM_NOTIFY_PROGRESS:
if ($bytes_transferred > 0) {
if (!isset($filesize)) {
printf("
Unknown filesize.. %2d kb done..", $bytes_transferred/1024);
} else {
$length = (int)(($bytes_transferred/$filesize)*100);
printf("
[%-100s] %d%% (%2d/%2d kb)", str_repeat("=", $length). ">", $length, ($bytes_transferred/1024), $filesize/1024);
}
}
break;
}
}
isset($argv[1], $argv[2]) or usage($argv);
$ctx = stream_context_create();
stream_context_set_params($ctx, array("notification" => "stream_notification_callback"));
$fp = fopen($argv[1], "r", false, $ctx);
if (is_resource($fp) && file_put_contents($argv[2], $fp)) {
echo "
Done!
";
exit(0);
}
$err = error_get_last();
echo "

";
exit(1);
?>
Executing the example above with: php -n fetch.php http://no2.php.net/get/php-5-LATEST.tar.bz2/from/this/mirror php-latest.tar.bz2
will output something similar too:
