Scala's implementation of type classes is rather verbose. One way to reduce the verbosity is to introduce so-called "Operation Classes". These classes will automatically wrap a variable/value when they are imported to extend functionality. To illustrate this, let us first create a simple ...

class My_Plugin() { function __construct() { add_action( 'wp_enqueue_scripts', array( $this, 'init_fe_assets' ) ); } public function init_fe_assests() { wp_enqueue_style( 'my-plugin', plugin_dir_url( __FILE__ ) . 'assets/css/frontend/plugin.css', array(), '0.0.1', true ); ...

PHPUnit provides the following function to assert whether an object is an instance of a class: assertInstanceOf($expected, $actual[, $message = '']) The first parameter $expected is the name of a class (string). The second parameter $actual is the object to be tested. $message is an optional ...

PHP Classes are powerful tool for improving code organization and minimizing naming collisions. At some point or another, the question of how to create an action hook for a class method inevitably arises. The $function_to_add argument is often shown as a string containing the function's name, howev...
