laravel controller shell_exec('composer update');

I would like to execute the following command : composer update in my controller in laravel, however this one does not work. On the other hand the command composer info works perfectly.

When I execute composer update in a command prompt all my dependencies are correctly updated in the laravel vendor file but when I try to execute composer update in my controller nothing happens.

here is my code :

$data['output'] = shell_exec( 'cd '. base_path() .' && composer update' );
dd($data);

and here is the result :

array:1 [▼
  "output" => null
]

Could you help me to understand why composer update does not work in a controller ? I would like to update my dependencies in a controller without the command prompt.

Thank you.

From the php docs for shell_exec():

The output from the executed command or NULL if an error occurred or the command produces no output.

Sounds like you'd be better off using passthru() instead as that will give you the erroneous output.

Speaking of erroneous, this is idea sounds like a recipe for unmitigated disaster.
