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();   
}   
 ?>
