will be executed if there’s an exception in the try block: try { //do something } catch (Throwable $e) { //we can do something here if an exception happens } Notice that we have an Exception object to get more information about the exception, like this: try { //do something } catch (Throwable $e) { echo $e->getMessage(); } Let’s do an example. For example by mistake I divide a number block, the program ends successfully, telling me the problem: try { echo 1 / 0; } catch (Throwable $e) { echo $e->getMessage(); } 62 Of course this is a simple example but you can see the
