Call to undefined function App\Http\Controllers\exec()-CodePudding

Please help me. The website works fine in the local host, but it is having error in the C panel. How to solve? the path is: app/config/app.php

CodePudding user response：

From your image, I'm supposing you defined the public function exec() function somewhere above or below in your controller. You cannot reference to it that way since its a method in your controller class.

So change it to this instead. $macAddr = $this->exec('getmac');

CodePudding user response：

you can use Process Component of Symfony that is already in Laravel

http://symfony.com/doc/current/components/process.html

use Symfony\Component\Process\Process;
use Symfony\Component\Process\Exception\ProcessFailedException;

inside your elcdetails use

$macAddr = new Process('getmac');
$macAddr->run();

// executes after the command finishes
if (!$macAddr->isSuccessful()) {
    throw new ProcessFailedException($macAddr;
}

//or whatever you want to do with the output. 

echo $macAddr->getOutput();

note that, if you are trying to get the client mac address, short answer is you cannot.
