Laravel5 using a try catch instance to explain

This article mainly describes the Laravel5 use try catch knowledge, the need for friends can refer to the following

Using the following code in LARAVEL5 does not catch the exception

try{Var_dump ($val);} catch (Exception $e) {var_dump ($e); Echo $e->getmessage ();}

Laravel 5 times the controller is forced to be placed under a sub-namespace so that the Exception class under the root namespace cannot be called directly. The controller of the Laravel 4 is directly available under the name space. After PHP 5.3 All classes are defaulted to the namespace, and if not declared, the default is under the top-level namespace.

So to use the syntax of the try catch, either the code uses use \exception at the very beginning, or catch (\exception $e). So the right way to use it is

try{Var_dump ($val);} catch (\exception $e) {var_dump ($e); <br><br>echo $e->getmessage (); <br>}

Ps:laravel 5 Try Catch problem: unable to detect Exception

In a recent project, try Catch was attempted, and it was found to have been unsuccessful

try{Var_dump ($val);} catch (Exception $e) {var_dump ($e);}

In PHP, this code should print the value of $e. However, in Laravel 5, it is not. This is because Laravel 5 enforces the PSR Standard and must use the correct namespace.

So to use the syntax of the try catch, either the code uses use \exception at the very beginning, or catch (\exception $e). So the right way to use it is

try{Var_dump ($val);} catch (\exception $e) {var_dump ($e);}
