Shared classes of the PHP Ride framework.

What's In This Library

Decorators

Decorators are used to convert values from one context into another. They should only act when the incoming value is handable.

Check this code sample:

<?php

use ride\library\decorator\DateFormatDecorator;
use ride\library\decorator\StorageSizeDecorator;
use ride\library\decorator\VariableDecorator;

// decorate dates into a formatted date
$decorator = new DateFormatDecorator();
$decorator->setDateFormat('y-m-d');
$result = $decorator->decorate(1372582573); // 2013-06-30
$result = $decorator->decorate(new DateTime('30 June 2013')); // 2013-06-30

// decorate byte values into human readable format
$decorator = new StorageSizeDecorator();
$result = $decorator->decorate(5000); // 4.88 Kb

// decorate variables into a output string
$decorator = new VariableDecorator();
$result = $decorator->decorate(null); // 'null'
$result = $decorator->decorate(true); // 'true'
$result = $decorator->decorate(array('key' => 'value')); // '["key" => "value"]'
$result = $decorator->decorate($decorator); // 'ride\library\decorator\VariableDecorator'

Autoloader

The autoloader of the Ride framework is a PSR-0 autoloader.

It handles class names like:

• ride\library\Autoloader: checked as ride/library/Autoloader.php
• ride_library_Autoloader: checked as ride/library/Autoloader.php and ride_library_Autoloader.php

Check this code sample:

<?php

use ride\library\Autoloader;
use ride\library\StringHelper;

require_once('path/to/ride/library/Autoloader.php');

$autoloader = new Autoloader();
$autoloader->addIncludePath('module1/src');
$autoloader->addIncludePath('module2/src');
$autoloader->addIncludePath('application/src'); // last added path will be checked first
$autoloader->registerAutoloader();

// go and use some classes
$string = StringHelper::generate();

Error Handler

The error handler of the Ride framework simply converts handable errors into exceptions.

Check this code sample:

<?php

use ride\library\ErrorHandler;

$errorHandler = new ErrorHandler();
$errorHandler->registerErrorHandler();

try {
    $tokens = explode(null);
} catch (Exception $e) {
    // ErrorException thrown
}

String Helper

The string helper comes in handy when processing values.

<?php

use ride\library\StringHelper;

$string = "Let's create a stràngé STRING";
$result = StringHelper::safeString($string); // 'lets-create-a-strange-string'
$result = StringHelper::safeString($string, '_', false); // 'Lets_create_a_strange_STRING'
$result = StringHelper::startsWith($string, array('yes', 'no')); // false
$result = StringHelper::startsWith($string, array('yes', 'no', 'Let')); // true
$result = StringHelper::startsWith($string, 'let'); // false
$result = StringHelper::startsWith($string, 'let', true); // true
$result = StringHelper::truncate($string, 12); // 'Let's...'
$result = StringHelper::truncate($string, 12, '...', true); // 'Let's cre...'
$result = StringHelper::generate(10); // a random string of 10 characters

Timer

A timer can be used to track time of actions. It has a detail of microseconds.

<?php

use ride\library\Timer;

$timer = new Timer();
$timer->reset();
$time = $timer->getTime(); // get the current time and keep on going
$time = $timer->getTime(true); // get the current time and reset

Installation

You can use Composer to install this library.
