The specific usage of try{} and catch{} in PHP

try{}catch{} in PHP is exception handling. Put the code to be executed into the TRY block. If an exception occurs in a certain statement during the execution of these codes, the program jumps directly to the CATCH block, represented by $e Collect error information and display. Any code that calls a method that may throw an exception should use a try statement. The Catch statement is used to handle exceptions that may be thrown.

< ?php try { $mgr = new CommandManager(); $cmd = $mgr->getCommandObject("realcommand"); $cmd->execute(); } catch (Exception $e) { print $e->getMessage(); exit(); } ?>
