Fatal error: Uncaught Error: Function name must be a string in /ajax.php:44

[Smir]

Just installed and can't ping, traceroute or anything to do with that area.
Fatal error: Uncaught Error: Function name must be a string in /ajax.php:44 Stack trace: #0 {main} thrown in /ajax.php on line 44
Line 44 of ajax.php reads;
$output = $lg->$_GET['cmd']($_GET['host']);

I will do this string for case:

	switch ($_GET['cmd']) {
		case "host":
			$output = $lg->host($_GET['host']);
			break;
		case "mtr":
			$output = $lg->mtr($_GET['host']);
			break;
		case "mtr6":
			$output = $lg->mtr6($_GET['host']);
			break;
		case "ping":
			$output = $lg->ping($_GET['host']);
			break;
		case "ping6":
			$output = $lg->ping6($_GET['host']);
			break;
		case "traceroute":
			$output = $lg->traceroute($_GET['host']);
			break;				
		case "traceroute6":
			$output = $lg->traceroute6($_GET['host']);
			break;
	}

Whats this for??

• Whats this for??
  This is fix.

Not all people are programmers and sometimes come to the github to find a solution to the problem and nothing more. I wrote a simple solution to this problem.

I have no idea what you posted?

do you mean overwrite line44 with what you posted?

[Volodya1234]

• do you mean overwrite line44 with what you posted?

Yes. It is necessary to rewrite this function in line44 to the code that I wrote above.

[Pulseeey]

I just rewrote it to this, PHP 7 likes it now.
$output = $lg->{$_GET['cmd']}$_GET['host']);

[InsaneSplash]

$output = $lg->{$_GET['cmd']}($_GET['host']);

There is a missing ( in @Volodya1234 's code

[yavg]

after i change $output = $lg->$_GET'cmd';
to $output = $lg->{$_GET['cmd']}($_GET['host']);
my lg is work now.
