Helps to create PHQL queries using an OO interface

<?php

$params = [
    "models"     => ["Users"],
    "columns"    => ["id", "name", "status"],
    "conditions" => [
        [
            "created > :min: AND created < :max:",
            [
                "min" => "2013-01-01",
                "max" => "2014-01-01",
            ],
            [
                "min" => PDO::PARAM_STR,
                "max" => PDO::PARAM_STR,
            ],
        ],
    ],
    // or "conditions" => "created > '2013-01-01' AND created < '2014-01-01'",
    "group"      => ["id", "name"],
    "having"     => "name = 'Kamil'",
    "order"      => ["name", "id"],
    "limit"      => 20,
    "offset"     => 20,
    // or "limit" => [20, 20],
];
