# CREED[#](https://creed.apps.wayne.edu/docs/#creed)

![php ^8.3](https://creed.apps.wayne.edu/docs/readme/badges/php.svg) ![license MIT](https://creed.apps.wayne.edu/docs/readme/badges/license.svg) ![policy schema v1, 6 components](https://creed.apps.wayne.edu/docs/readme/badges/policy.svg)

**The standard everything rests on.**

**Not to be confused with:** CREED is the rules; PROCTOR checks an app against them.

This page orients you: what CREED is, what it ships, and where to go next.

CREED is the Wayne State app stack's version policy, as data. One file, `policy/policy.json`, lists the support dates for PHP, Laravel, Node, MySQL, Vue and Inertia, plus the rules every check runs against. A small framework-free PHP reader, `Waynestate\Creed\Policy`, answers the one question every tool needs: what state is this version in, on this date?

## Usage[#](https://creed.apps.wayne.edu/docs/#usage)

```php
use Waynestate\Creed\Policy;
use Waynestate\Creed\State;

$policy = Policy::bundled();

// What state is PHP 8.2 in, on this date?
$state = $policy->stateOf('php', '8.2', new DateTimeImmutable('2026-10-27'));
// State::Security

// What is the oldest PHP an app may declare?
$floor = $policy->oldestSupported('php', new DateTimeImmutable('2026-10-27'));
// '8.2'
```
