Caddy is a another alternative to Apache or nginx . For me the biggest advantage is that it’s only one binary file to work with. It’s easy to run, setup and just “works”. It’s super modern – handles HTTP2 and automatic HTTPS encryption using let’s encrypt certificates. Obviously it has plenty of other features but we focus only on speed of deployment.

From many reasons I was always using  SQL_CALC_FOUND_ROWS to get total number of records, when I was running limited query. Never especially thought about it, until i had some super performance issues with one of my projects. Obviously after quick profiling and googling  i found people complaining about FOUND_ROWS() low performance . I was not aware how big impact it was until I tested.

PHP 7.0 it’s already a while on the market. Let’s install it on EC2 instance.  Here you can find a quick recipe:

This article is related to my previous one about setting up PHPCodeSniffer with CodeIgniter coding standards.

Installation on Linux boxes is pretty yeasy:

sudo pear channel-update pear.php.net
yum install php-pear-PHP-CodeSniffer php-phpunit-phpcpd

On Mac OS X you have couple options. Pear or Homebrew:

brew install php-code-sniffer

And following that, on regular boxes CodeSniffer will be here:

/usr/share/pear/PHP/CodeSniffer/Standards

on Mac OS CodeSniffer will be located here:

/usr/lib/php/pear/PHP/CodeSniffer/Standards or… /usr/local/Cellar/php-code-sniffer/1.5.6/CodeSniffer/Standards

CodeIgniter standard can be downloaded from this location  https://github.com/thomas-ernest/CodeIgniter-for-PHP_CodeSniffer

Quick tutorial how to setup proper unit testing with PHPUnit and CodeIgniter 3.0.
We need couple elements

1. CodeIgniter – we are working with version 3.0rc3
2. PHPUnit  – latest one

If you don’t have phpunit installed globally, you can go with composer, just add section to your composer.json

{
  "require-dev": {
    "phpunit/phpunit": "4.1.*"
  }
}

and then
composer.phar install
and after while we have
./vendor/bin/phpunit
working phpunit.

let’s create phpunit.xml.dist

next step will require create separate bootstrap file for PHPUnit. Just copy cp index.php tests/Bootstrap.php
We have to make 2 small amends.
