View ---- [](#view) Helper for loading views. Uses the Files class. ``` use underDEV\Utils\Files; use underDEV\Utils\View; // argument should be the main plugin file $files = new Files( __FILE__ ); $view = new View( $files ); // set some view var $view->set_var( 'var_name', 'value' ); // load view // this will load ./views/parts/menu.php $view->get_view( 'parts/menu' ); ``` In template file you can get vars ``` get_var( 'var_name' ); ?> ``` To have different scopes in templates you have to instantinate different classes. Cache ----- [](#cache) Interface for cache. Has two implementations: - Object Cache - if WordPress cache is not set it will not persist - Transient Cache ### Basic usage [](#basic-usage) ``` use underDEV\Utils\Cache\ObjectCache; use underDEV\Utils\Cache\Transient; // create new cache object giving it a key and group $cached_object = new ObjectCache( 'object_key', 'object_group' ); var_dump( $cached_object->get() ); // inspect cached value // create new transient cache giving it a key and expiration in seconds $transient_cache = new Transient( 'transient_key', 3600 ); var_dump( $transient_cache->get() ); // inspect cached value ``` ### Injecting cached element into a class [](#injecting-cached-element-into-a-class) ``` use underDEV\Utils\Interfaces\Cacheable; use underDEV\Utils\Cache\ObjectCache; use underDEV\Utils\Cache\Transient; class MyClass { /** * Cached object * @var mixed */ protected $cached_element; /** * Constructor * @param Cacheable $cached_element */ public function __construct( Cacheable $cached_element ) { $this->cached_element = $cached_element; } public function inspect_element() { var_dump( $this->cached_element->get() ); } } $myclass = new MyClass( new ObjectCache( 'object_key', 'object_group' ) ); $myclass->inspect_element(); // dumps object cached variable // you can substitute MyClass constructor argument with // any object of class that implements Cacheable $myclass = new MyClass( new Transient( 'transient_key', 3600 ) ); $myclass->inspect_element(); // dumps cached transient variable ``` See Cacheable interface for all available methods. Dice ---- [](#dice) Dependency injection container. Forked from Tom Butler's Dice lib. Compatible with PHP 5.4 [Dice usage](https://r.je/dice.html) ### Health Score 31 — LowBetter than 68% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity19 Limited adoption so far Community8 Small or concentrated contributor base Maturity63 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~92 days Recently: every ~116 days Total 6 Last Release 2754d ago ### Community Maintainers ![](https://www.gravatar.com/avatar/fd1fdcaa145bfe7d6d015951da54a856f34988c581ae5a2de4c9df6d3b696ebc?d=identicon)[kubitomakita](/maintainers/kubitomakita) --- Top Contributors [![jakubmikita](https://avatars.githubusercontent.com/u/18362490?v=4)](https://github.com/jakubmikita "jakubmikita (44 commits)") --- Tags wordpresswordpress-plugins ### Embed Badge ![Health badge](/badges/underdev-utils/health.svg) ``` [![Health](https://phpackages.com/badges/underdev-utils/health.svg)](https://phpackages.com/packages/underdev-utils) ``` ### Alternatives [steffenbrand/dmn-decision-tables PHP library to programmatically create DMN decision tables. 1916.7k](/packages/steffenbrand-dmn-decision-tables) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
