Interface no I prefix (ARCH7003)

Key php.naming.interface-no-i-prefix · Severity info · Category naming

The PHP convention discourages prefixing interface names with I. This Hungarian-style prefix is redundant; the abstraction is clear from context and the implements clause.

Incorrect

<?php

interface IRepository
{
    public function find(int $id): ?object;
}

Correct

<?php

interface Repository
{
    public function find(int $id): ?object;
}

Fix

Drop the I prefix; if a role marker is needed, use a meaningful suffix instead.
