<?php
/**
* Mageia maintdb quick filter.
* Make use of http://pkgsubmit.mageia.org/data/maintdb.txt data.
*
* This only supports mapping 1 user to several packages
* or 1 package to 1 user.
*
* @param string $uid (GET param) user id
* @param string $pkg (GET param) package name
* @param mixed $txt (GET param) whether to return result in text or JSON (default)
* @param string $iurt (GET param) return a iurt-specific response format: only the username
*
* @return string
*
* Returned format is JSON format as a default:
* <code>
* {"user_name": {"packages" => ["package_name1", "package_name2"]}}
* </code>
*
* either text format (use ?txt in query string)
* <code>
* package_name user_name
* package_name2 user_name2
* </code>
*
* either specific, iurt format (use ?pkg=...&iurt in query string)
* <code>
* user_name
* </code>
*
*
* TODO check if preg_match_all() is more efficient than exec('grep ...')
* TODO if so, check security concerns for $uid and $pkg
