Class name PascalCase (ARCH7001)

Key php.naming.class-name-pascalcase · Severity warning · Category naming

PSR-1 requires class names to be declared in PascalCase (StudlyCaps). snake_case or camelCase class names break the convention and hurt autoloading and readability.

Incorrect

<?php

class user_account
{
    public function balance(): int
    {
        return 0;
    }
}

Correct

<?php

class UserAccount
{
    public function balance(): int
    {
        return 0;
    }
}

Fix

Rename the class to PascalCase: capitalize each word with no separators.
