treehousetim/exception

A PHP Exception class to use as a base for exception handling in well structured web apps.

Installing

composer require treehousetim/exception

Using

After installing, create your own class that extends treehousetim\exception\Exception.

Each namespace area of your code should implement its own Exception.php

Each Exception class should create class constants for relevant codes.

Exceptions are thrown with a variable length parameter list with the code as the very last parameter.

Throwing

To throw an exception, you can build up your message with multiple parameters. Place your code as the last parameter. Exception messages are concatenated from the parameters with PHP_EOL as the glue.

throw new Exception(
	'This',
	'is',
	$lib->getErrorText(),
	'bad',
	Exception::normalError
);
