This is a hands-on book. You won’t be able to complete it by reading it in a metro on a way to work. You’ll have to read this book while in front of a computer getting your hands dirty. You will learn developing console and web applications as well as micro services. This book is interesting for intermediate developers as well as beginners.

Learning PIMF

One of the best ways to learn PIMF is to read through the entire of its documentation. This guide details all aspects of the framework and how to apply them to your application. http://docs.pimf-framework.de

Read the PIMF Starter book almost anywhere. Available as a PDF, EPUB and MOBI. You can now read it on all devices, as well as offline: http://book.pimf-framework.de

Eventually, you might get stuck and in need of help. Or you might want to write a review or comment on the book’s content. Please post your thoughts on this blog post. If you prefer one-on-one discussion, feel free to send me an email to gjero@krsteski.de, and I’ll give my best to help you out.

PIMF vs. Silex

27. November 2015

0 Kommentare

This performance comparison was done by TechEmpower, Inc. CA. They made the benchmark of many web application frameworks executing fundamental tasks such as JSON serialization, database access, and server-side template composition. Each framework is operating in a realistic production configuration. Results are captured on physical hardware. The test implementations are largely community-contributed and all source is available at the GitHub repository.

In the following tests, TechEmpower have measured the performance of several web application platforms, full-stack frameworks, and micro-frameworks (collectively, „frameworks“). For more information, read the introduction, motivation, and latest environment details.

Hardware

Peak: Dell R720xd dual Xeon E5-2660 v2 (40 HT cores) with 32 GB memory; database servers equipped with SSDs in RAID; switched 10-gigabit Ethernet

Platform

Current versions of: Linux, PHP-FPM, nginx on Linux, MySQL on Linux

Single query test

In this test, each request is processed by fetching a single row from a simple database table. That row is then serialized as a JSON response.

Multiple queries test

In this test, each request is processed by fetching multiple rows from a simple database table and serializing these rows as a JSON response. The test is run multiple times: testing 1, 5, 10, 15, and 20 queries per request. All tests are run at 256 concurrency.

Should a function have only one return statement?

13. August 2015

9 Kommentare

I would say that you can definitely have more than one return statement. Therefore I would like to suggest to:

1.) Minimize the number of returns in each routine. It’s harder to understand a routine if, reading it at the bottom, you’re unaware of the possibility that it returned somewhere above.

2.)Use a return when it enhances readability. In certain routines, once you know the answer, you want to return it to the calling routine immediately. If the routine is defined in such a way that it doesn’t require any cleanup, not returning immediately means that you have to write more code.

Question: Which of the functions shown below would you prefer and why?

Version 1:

function getTemplateId(array $config, $id)
{
    if (array_key_exists($id, $config)) {
        $templateId = $config[$id];
    } else {
        $templateId = 0;
    }

    return $templateId;
}

Version 2:

function getTemplateId(array $config, $id)
{
    if (array_key_exists($id, $config)) {
        return $config[$id];
    }

    return 0;
}

Please write your answer as a comment :-)

Präsentation über PIMF PHP Micro Framework

2. Juli 2014

0 Kommentare

Wer am 6 Juni nicht bei der PHPUG Köln/Bonn dabei sein konnte – kann sich hier die Präsentation über „PIMF PHP Micro Framework“ anschauen. Ihr könnt mehr über die Entstehungsgeschichte lernen und bekommt ein Überblick über die gängigen PIMF Framework Features.

Danach könnt ihr euch eins der PIMF-bündel anschauen. Das sind PHP-App-Bündel die PIMF zusammen mit gängige Web Technologien wie: MySQL, SQLite oder Twig einsetzen. Probiert es aus und schreibt mir ein Feedback. Viel Spaß!

Hier der Link zu der Präsentation http://slides.com/gjerokrsteski/pimf-php-micro-framework/
