Classes and functions that extends PHP/ZF3 functionalities

Installation

Simply use the composer:

composer require voyteck/extlibs

Class Voyteck/ExtLibs

Class delivers static functions for various purposes

Function Voyteck/ExtLibs::byteOn(int $value, int ...$bytes)

Functions returns TRUE if within $value bytes mentioned in (varied number) $bytes are ON. For example number 5 can be split into bytes 1x1 + 0x2 + 1x4 - which means bytes 1 and 4 are ON. This way within single integer number it is possible to write number of ON/OFF options.

Usage examples

• Voyteck\ExtLibs::byteOn(5, 1) will return TRUE.
• Voyteck\ExtLibs::byteOn(5, 1, 4) will return TRUE.
• Voyteck\ExtLibs::byteOn(5, 2) will return FALSE.

Function Voyteck/ExtLibs::generateRandomString($length = 10)

Allows to create random string of various length

View Helper Voyteck/VExtLibs/configValueHelper

A simple helper that once invoked will retrieve (and print on screen) a configuration value Helper should be invoved with parameters: __invoke(array $configPath = [], $quoteStrings = true)

• $configPath - contains path from configuration that should be retrieved. If not provided - the whole configuration is shown. The path should be provided in the form of an array with elements that shows "deeper and deeper" levels of configratuin key to be retrieved
• $quoteStrings - boolean parameter specifying whether string paraneter values should be quoted

Usage

The helper needs to be added into 'view_helpers' configuration entry. Most common way of doing this would be adding an entry:

...
'view_helpers' => [
	...
	'aliases' => [
		...
		'configValueHelper' => \Voyteck\VExtLibs\View\Helper\configValueHelper::class,
	],
],
...

Then you can use the helper directly in the view files - e.g:

...
<?php echo $this->configValueHelper(['route', 'routes', 'test', 'type', 'options', 'route']); ?>
...

will print out on the page quoted route value for route 'test'.
