ErrorControlChain

class ErrorControlChain

Class ErrorControlChain

Runs a set of steps, optionally suppressing uncaught errors or exceptions which would otherwise be fatal that occur in each step. If an error does occur, subsequent steps are normally skipped, but can optionally be run anyway.

Usage:

$chain = new ErrorControlChain(); $chain->then($callback1)->then($callback2)->thenIfErrored($callback3)->execute();

WARNING: This class is experimental and designed specifically for use pre-startup in main.php It will likely be heavily refactored before the release of 3.2
