<p>Этот конфиг правится только умными людьми, которые знают PHP и не нужно создавать для них лишние уровни абстракций.</p>
<p>Задача - загрузить этот конфиг в программу. Просто сделать include('config.php') нельзя, потому что можно нечаянно перезаписать какую-то переменную, а в конфигурационном файле писать $config['param1'], $config['param2'] слишком долго.<br />

<p>Но функция processOrders($customerId) работает как-то странно, при каждом новом вызове съедая 100Мб памяти. И после 40 клиентов заканчивается физическая память и начинается жуткий своп.</p>
<p>Программист-идеалист разбирался бы в этой странной функции долго и нудно, смотрел, где утечка памяти, оптимизировал алгоритм. Я посмотрел мельком на эту функцию, понял, что на её понимание может уйти несколько часов. Потом заметил, что для каждого клиента обработка заказов происходит только один раз и можно просто разбить работу скрипта на части. Пусть скрипт обрабатывает 10 клиентов (съедая всего 1Гб памяти), а потом перезапускается.</p>

<p>При этом получаем дополнительный бонус - если надо будет обработать заказы новых клиентов, то старые не будут заново обрабатываться, так как результат закеширован.</p>

<p>Массив $searchEngines был почти полностью одолжен из скрипта Google Analytics urchin.js. Поэтому поддерживаются все поисковики, которые сейчас определяет Google Analytics плюс добавлены несколько русских и украинских поисковиков.</p>

Называются разные аргументы - более быстрый, гибкий, удобный и так далее.</p>
<p>После того, как я начал пользоваться CakePHP ко мне неожиданно пришло просветление - это было как раз то, что я хотел. Но иногда возникают задачи, когда действительно нужны простейшие шаблонизаторы и CakePHP становится слишком тяжёлой артиллерией.<br />

<p>И тут все сразу смотрят в сторону eval. Первое, что приходит в голову - написать eval(file_get_contents('template.htm')). И, конечно же, это не работает. Потом читается документация и пишется что-то вроде eval('echo("'.file_get_contents('template.htm').'");');. Но и это тоже не работает.</p>
<p>А потом наконец включается мозг и приходит понимание, что нужно учится у умных людей. Например, тех, кто написал CakePHP <img src='http://php.southpark.com.ua/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /><br />
Они устанавливают нужные переменные, отключают вывод на экран, инклюдят шаблон, берут вывод из буфера и обрабатывают. Обычно даже это сильно сложно, можно переменные не устанавливать.</p>

<p>Преимущество в том, что работает очень быстро, кода мало, верстальщикам можно объяснить суть шаблонов за пару минут.</p>
<p>Если вы знаете, как сделать шаблонизатор ещё проще - расскажите.</p>

			<content:encoded><![CDATA[<p>В каждом сборнике советов о том как сделать блог более популярным есть "Напишите Top10 чего-то". Вот я решил написать Top10. Но как истинный программист, вместо 10 бессмысленных фактов написал алгоритм как правильно выбирать Top10 чего-то.</p>
<p>Допустим, у вас есть сайт со статьями и вы хотите сделать Top10 статей, учитывая количество их просмотров. Не торопитесь, подумайте сначала, зачем вы хотите это сделать. Наверное, чтобы показать людям статьи, которые могут быть им наиболее интересны. Но показывая одни и те же Top10, вы искусственно увеличиваете количество просмотров статей, которые находятся в топе и они, возможно, случайно туда попав, уже никогда не исчезнут. В то же время посещаемость надо учитывать, потому что всё же корреляция посещаемость-интересность есть.<br />
<span id="more-61"></span></p>
<p>В моём алгоритме, чем больше рейтинг, тем выше будет <strong>вероятность</strong> появления записи в топе и <strong>вероятность</strong> более высокого положения там. Записи с нулевым рейтингом появляются только тогда, когда показаны записи с ненулевым рейтингом и выбираются случайно.</p>
<p>Используется функция примерно так</p>

<p>Естественно, лучше применять хитрые оценки для выставления рейтингов, например,<br />
(1000 - кол-во дней с опубликования)+(100 * кол-во комментариев)+(кол-во просмотров)<br />
Ну и можно применять это к "лучшим" пользователям, комментариям, товарам,...</p>
