MissingThrowsDocblock

A function throws an exception that is not declared in its @throws docblock.

Example

<?php
function open(string $path): resource {
    if (!file_exists($path)) {
        throw new \RuntimeException("Not found: $path"); // not declared in @throws
    }
    return fopen($path, 'r');
}

How to fix

Add a @throws \RuntimeException annotation to the docblock.
