Random Weighted Conditions

Pass a set of conditions and weights, and build a random condition generator.

i.e.

When serving fruit...

• Serve Apples 50% of the time
• Serve Oranges 10% of the time
• Serve Grapes the rest of the time
• Serve Jackfruit never

Example

require_once 'class-random-weighted-conditions.php';

$conditions = array(
	'apples'    => 50,
	'oranges'   => 10,
	'grapes'    => null,
	`jackfruit` => 0,
);

$colors = new \WPAZ_RWC\V_1_2\Random_Weighted_Conditions( $conditions );

// will be `apples` 50%, `oranges` 10% and `grapes` 40%
echo $colors->get_random_condition();

How it Works

Step 1

Developer provides array() of key => val pairs with condition keys and weight values.

Possible Values:

• 0-100 are treated as percentage weights. 0 completely excludes a condition.
• All other true-testing empty() values are giving equal distribution of remaining total, following preassigned weights

Step 2

Class validates data and creates an array with 100 string conditions (total can be modified, conditions looped sequentially), based on weights provided.

Step 3

Class randomly selects one of strings.
