  • How to Use Linux for Composer to Deploy to the Cloud
    How To Use Linux for Composer to Deploy to the Cloud Developers are placed into a tough situation when asked to deploy a working Docker container- based application up to a cloud service. Traditionally, in addition to hours spent wading through cloud services documentation, a deployment was a messy operation involving a combination of docker exec, zip, unzip, sftp and ssh to get everything up and running. In this guide we show you how to deploy directly from your local computer to Linux for PHP Cloud Services in minutes using a fantastic new tool called Linux for Composer . What the Heck is Linux for Composer? At this early stage you may be thinking: well … I’ve heard of Linux, and I’ve heard of Composer … but what the heck is Linux for Composer (LfC)? LfC is yet another incredible tool that comes out of the Linux for PHP project. The brainchild of Foreach Code Factory CEO Andrew Caya, LfC is a PHP package, hosted on github.com and packagist.org, made available via Composer. Obviously any package residing on packagist.org is not Linux, nor the Linux kernel, but what LfC allows you to do is to define a standard composer.json file that includes an extra set of directives that essentially mimics some of the things you can do using Docker Compose. The main difference, however, is that LfC will proceed to not only build the Docker container for you, but actually upload it to a cloud service using credentials you supply. So, effectively, as long as your Docker container works locally, with a single command, that same container is reconstructed instantly live on the Internet.

  • Comparing Performance of Plain PHP and Four of Its Popular Frameworks
    Thesis Project Comparing Performance of Plain PHP and Four of Its Popular Frameworks Author: Jone Samra Supervisor: Johan Hagelbäck Examiner: Sabri Pllana Semester: VT 2015 Subject: Computer Science Abstract The objective of this study is to evaluate performance of four popular PHP frameworks Laravel, Symfony, CodeIgniter and Phalcon together with the plain PHP. The decision of making this study was based on the fact that there is a lack of comparison tests between the most popular PHP frameworks. Visiting the official websites of these frameworks, the first thing to notice is the slogans that have been made by the core teams. The majority of these slogans contain quality attributes like speed and high performance. As a developer looking for performance in your next project, choosing the right PHP framework by these slogans is not that easy. Therefor, the performance of these frameworks is put to the test. And to do that, three experiments are conducted in which five functionally equivalent PHP applications are developed and used as targets. One version of these applications represents the plain PHP and the other four represent the four mentioned frameworks. The experiments are conducted in two sessions. The first session deals with the execution time and the stack trace measurements while the second one is covering the measurement of the memory usage consumption. The result outcome of these experiments has been analyzed and interpreted in order to expose the performance of the targeted frameworks. The experiment results prove that the targeted frameworks perform differently compared with each other and the PHP stack. Plain PHP and Phalcon are performing well while the other three frameworks have both mediocre and low performance.
