Constant Casing (ARCH7006)

Key php.naming.constant-screaming-snake · Severity info · Category naming

In PHP, class- and module-level constants should be written in UPPER_SNAKE_CASE. This convention visually separates constants from variables and clarifies intent.

Incorrect

<?php

class Config
{
    const maxRetries = 3;
    const default_timeout = 30;
}

Correct

<?php

class Config
{
    const MAX_RETRIES = 3;
    const DEFAULT_TIMEOUT = 30;
}

Rename constants to UPPER_SNAKE_CASE: all uppercase, words separated by underscores.
