“Upgrading to PHP 7” book review:

PHP 7—the most dramatic update to the language in over a decade—has arrived. This O’Reilly report provides you with a short guide to the major changes in this new release, including a revamped engine (Zend Engine 3), a bunch of new features, and lots of language cleanup. You’ll learn about basic language changes, deprecated features, Unicode enhancements, changes in Object-Oriented programming, and other enhancements.

– Deprecated features, starting with alternative PHP tags and POSIX-compatible regular expressions
– Uniform Variable Syntax, including consistency fixes and new syntax
– Basic language changes, such as new operators, constant arrays, new functions, and regular expressions
– Expectations and Assertions

Resources To Learn and Get Good with Laravel 5

I played around a little with Laravel, a couple of years ago, during their version three, but then I ended up diving deep into the Yii Framework instead (work related reasons).

Recently, I decided to go back into it, after they release the version 5, and I was surprised with the huge rise that it had in terms of community and learning resources.

The following list of resources was compiled , for personal use, during my initial research to get up to speed with the new version of the framework. So, if you are trying to getting evolved with Laravel now, check this list first! 😉

Share a PHP package with Composer and Packagist

Hi there! In this quick tutorial we will see how to create a package for your PHP class/library with composer and publish it on

You probably are already using composer to manage dependencies in your projects and search for packages to speed up your development.

And guess what… creating your packages and giving back to the PHP community is as easy as requiring them!

Before we start…

(Skip this part if you already have composer installed and you project code on a version control system)

Installing composer

You will need composer installed on your system to create and test your packages so, if you don’t have it already, let’s go ahead and install it.

I recommend you install composer globally so then you can access it in any directory by just typing composer:

Although, if you are on windows or just want a to install composer locally for your project, you can check their quick start guide.

Billions in Change – Technology and Innovation to Build a Better Future


Manoj Bhargava is an entrepreneur, philanthropist, and founder and CEO of 5-hour Energy company. His net worth is over $4 billion, but the most interesting part about him, is that he is giving away more then 90% of it to build a better future for the world thought the movement Billions in Change.

Billions in Change is a movement to save the world by creating solutions, through technology and innovation, to the most basic global problems – water, energy and health.

They are working on several projects right now like:

  • Free Electric – A hybrid bicycle that you pedal for one hour and have electricity for one day.
  • Limitless Energy – Using graphene to conduct energy, in the form of heat, from underneath the earth, pollution free.
  • Rain Maker – Produce fresh water from sea water.
  • Renew – An ECP (External Counter Pulsation) device that can make people healthier by assisting the hearth pulsations and reducing heart problems

But I don’t want to spoil too much of the film because it really worths being watched!

This is a great history and Manoj’s vision and experience can be really inspiring.

As an example of that, I leave here some quotes retrieved from the film.

Awareness doesn’t reduce pollution, grow food or heal the sick. That takes doing!


If it doesn’t make a big difference, find something else to do. Life is too short to spend making things that don’t have a real impact. We are here to make a difference.


Somebody asked me once in an interview:

“What does an entrepreneur really need?”

And I said:

“Actually, only two things. Common sense and a sense of urgency.”

And they asked:

“From whom should we learn this stuff from?”

And my answer was:

“From your mom. She probably has done more management that your MBA professor. Because she has a budget, she got all those kids running around the house, hard to manage, and all of those things need to be done every day, seven days a week. That’s hard work! That’s learning on the job!”
