1.2.1107. Should Chain Exception¶
Chain exception to provide more context.
When catching an exception and rethrowing another one, it is recommended to chain the exception : this means providing the original exception, so that the final recipient has a chance to track the origin of the problem. This doesn’t change the thrown message, but provides more information.
Note : Chaining requires PHP > 5.3.0.
<?php
try {
throw new Exception('Exception 1', 1);
} catch (\Exception $e) {
throw new Exception('Exception 2', 2, $e);
// Chaining here.
}
?>
