Ruler is a simple, stateless production rules engine for PHP that lets developers define business rules as composable propositions (comparisons, logical operators) evaluated against a context. It provides both a fluent RuleBuilder DSL and a lower-level object API for building conditional rules with actions.

Use cases

• evaluate business rules in php
• build a rules engine for conditional logic
• check if values satisfy conditions like ranges
• define composable if-then rules without hardcoding
• implement feature gating or eligibility checks
• separate business rule logic from application code

When to choose

• you need a lightweight, stateless rules engine in PHP
• you want a readable DSL for composing comparison and logical operators
• you need rules evaluated against dynamic context values, including lazy closures

When to avoid

• you need a full forward-chaining inference engine or RETE algorithm
• you need persistent, hot-reloadable rules managed by non-developers
• your project is not PHP
