Description

GlobalType is a simple library that allows type checks on global arrays. Because by default the array elements are mixed, one has to check the element type before using. This library makes it easier to tell PHP what type you are expecting from a global array.

Requirements

The only requirement is PHP version 8.0 or higher.

Installation

composer require ocolin/global-type

Usage

Available Classes

GlobalType has a class for each of the PHP Globals:

Class	Global
COOKIE::class	$_COOKIE
ENV::class	$_ENV
FILES::class	$_FILES
GET::class	$_GET
GLOBALS::class	$GLOBALS
POST::class	$_POST
REQUEST::class	$_REQUEST
SERVER::class	$_SERVER
SESSION::class	$_SESSION

Available Methods

Every class shares the same functions which are used on the classes corresponding PHP Global

Method	Description
getString	Return a string or '' if not found.
getStringNull	Return a string or null if not found.
getInt	Return an int or 0 if not found.
getIntNull	Return an int or null if not found.
getFloat	Return a float or 0.0 if not found.
getFloatNull	Return a float of null if not found.
getBool	Return a bool or false if not found.
getBoolNull	Return a bool or null if not found.
getArray	Return an array or [] if not found.
getArrayNull	Return an array or null if not found.
getObject	Return same object or null if not found.

Arguments

Both the Null and non-Null methods take a name parameter, while the Null methods only take a name argument.

name - The name of the array key in the targeted PHP global.
default - If the element is not found or the type does not match, you can return a default value of your choice.

Basic Usage

use Ocolin\GlobalType\GET;
$_GET['parameter'] = 'value';

$value = GET::getString( name: 'parameter' );
// string(5) "value"

$value = GET::getInt( name: 'parameter' );
// int(0)

$value = GET::getIntNull( name: 'parameter' );
// NULL

$value = GET::getInt( name: 'parameter', default: 777 );
//int(777)
