Implement skipcq for ignoring issues

[sanket-deepsource]

We use the skipcq keyword to suppress a specific occurrence of an issue in the source code. We can implement the same for issues detected by Globstar.

Sample usage

<?php

function test_dangerous_eval() {
    $user_input = $_GET['input'];  // skipcq: php:dangerous_eval
    eval($user_input);

This will suppress the php:dangerous_eval checker from raising an issue on this line.
