Question

I been searching for this and I just seem to run into the same articles, in this code:

   try
    {
        //some code

    }
    catch(Exception $e){
        throw $e;
    }

Where does $e gets stored or how the webmaster see it? Should I look for a special function?

Answer 1

An Exception object (in this case, $e) thrown from inside a catch{} block will be caught by the next highest try{} catch{} block.

Here’s a silly example:

try {
    try {
        throw new Exception("This is thrown from the inner exception handler.");
    }catch(Exception $e) {
        throw $e;
    }
}catch(Exception $e) {
    die("I'm the outer exception handler (" . $e->getMessage() . ")<br />");
}

The output of the above is

I’m the outer exception handler (This is thrown from the inner exception handler.)
