README

This library provides object-oriented wrappers around some of the features of PHP affecting global scope.

The currently implemented features are:

• Constants
• Functions
• Echo / Print

Global state is evil. Avoid it wherever possible. Do not think this library makes it okay.

This library has two main use cases:

• when you're working in an environment where it's unavoidable, and you still want code you write as testable as possible
• while you're refactoring your code to get out of this mess

Usage

Install it with composer, adamquaile/php-global-abstraction.

Constants

<?php

$constants = new \AdamQuaile\PhpGlobal\Constants\ConstantWrapper();

$constants->set('key', 'value');
$constants->get('key');
$constants->isDefined('key');

Functions

<?php

$functions = new \AdamQuaile\PhpGlobal\Functions\FunctionWrapper(
    new FunctionCreator(),
    new FunctionInvoker()
);

# Create function with a specified name

$functions->create($callable, 'func_in_global_scope');
\func_in_global_scope($arguments);


# Create function and return its automatically generated name

$functionName = $functions->create($callable);
$$functionName($arguments);

# Call a function existing in global scope
$functions->invoke('strlen', 'hello world');

Echo / Print

<?php

$output = new \AdamQuaile\PhpGlobal\Output\EchoWrapper();

$output->output('Hello ', $world);
