How to use try catch

Question

I'm trying to make a catch try this:

Config::set( 'database.connections.information_schema', array ( 
    'driver'     =>  'mysql', 
    'host'       =>  'localhost', 
    'port'       =>  '3306', 
    'database'   =>  'information_schema', 
    'username'   =>  'root', 
    'password'   =>  '1', 
    'charset'    =>  'utf8', 
    'collation'  =>  'utf8_unicode_ci', 
    'prefix'     =>  ''
    // 'strict'    => false, 
)); 

try 
{
    $datos = DB::connection('information_schema')->getDatabaseName();    
    echo "Conectado correctamente a la base de datos: ".$datos.".";
} 
catch (Exception $e) 
{
    echo 'Error';
}

And when he goes right ejectua the try but obviously when to go for the catch does not show echo

What is exactly your problem? You think it never enter the catch when an error happen? — olibiaz, Mar 02 '16 at 21:32

Change your

catch (Exception $e)

to

catch (\Exception $e)

More info on importing/aliasing namespaces; you can also add use Exception; in the top of the file. Find more in the docs

I suppose the database connection is in some function/method. If it is not, just put the code in some function.

In case of error, we jump out of the function with return command and continue only if the code inside of try block succeeded.

Something like this:

...
try {
    $datos = DB::connection('information_schema')->getDatabaseName();    
} catch (Exception $e) {
    echo 'Error';
    return false;
}
//connected successfully
echo "Conectado correctamente a la base de datos: ".$datos.".";
...
