php try catch in Laraver framework does not work solution

I recently used the laravel framework and found that try catch had no effect and could not catch exceptions.

Then I tried it in the think framework and found that it didn't work either!

try{
    $i = 1/0;
}catch(Exception $e) {
    echo "error";
}

Finally found that the problem is in the Exception class!

You need to add \ (backslash) in front of it to work

Like this

try{
    $i = 1/0;
}catch(\Exception $e) {
    echo "error";
}

I found that not only the Exception class is needed, but all PHP automatically in the framework You need to add \

to all classes. If you don’t add it, the framework will look for it in its own class, which obviously won’t work! !
