5 New Features In PHP 7 That You Should Have A Look At
Oct 19, 2016 @ 09:43:05

If you've heard about the release of PHP 7 but aren't quite sure what it has to offer, check out this quick post on the StartTutorial site giving you a "top five" list of things this new version of the language has to offer.

But you must be wondering why PHP named its latest release PHP 7 and not PHP 6. Reason behind it is that, many of the PHP 6 releases were already implemented in PHP 5.3 and later, there was not really a proper reason just to change the name. What I am trying to say here is that we haven’t missed anything. Just to avoid the confusion with a dead project, PHP's latest release was named to PHP 7.

Is This Hype Valid for PHP 7? What It Actually Brings Forth for the Developers? Hop on and let’s take a deeper dive. Let's check out what new features PHP 7 has to offer. And what improvements those features will bring forth.

Their top five list covers some of the major improvements in the language:

  • Speed Improvement
  • Implementation of Type Declarations
  • Implementation of Error Handling
  • New Operators
  • CSPRNG Functions

There's a bit of explanation of each item on the list but you'll definitely want to refer to the PHP manual for more details and specifics on what changed in PHP 7.

Quick Tips for Writing Object Oriented Code in PHP
Jul 13, 2015 @ 10:58:14

On the Acquia blog Adam Weingarten has shared some tips for writing good (and modern) object-oriented code in PHP:

Recently I began working on a D8 module, but this isn't a story about a D8 module. The work I did provided me an opportunity to get back to my pre-Drupal object oriented (OO) roots. Writing OO code in PHP presented some curve balls I wasn’t prepared for. Here are some of the issues I encountered:

His tips touch on things like:

  • Using a code structure that can be autoloaded via PSR-4
  • Namespacing your classes
  • Working with types and type hinting
  • Using docblock comments for autocomplete in IDEs

There's also a few other quick topics he finishes the post out with: the lack of enums in PHP, working with associative arrays, no functional overloading and assigning responsibility to classes.

Allan MacGregor:
Hello Hack
Mar 25, 2014 @ 09:50:33

Allan MacGregor has a new post to his site introducing you to Hack, the recently released language from Facebook based on their work with the HipHop virtual machine.

Recently Facebook unveiled Hack, a new programming language that aims to provide developers with the tools to write and ship code quickly while catching errors on the fly. Hack is as programming language designed to work with HHVM and the same time it works seamlessly with PHP as Facebook lead devs. [...] So does that mean that Hack is just a faster more efficient PHP implementation, right? Wrong, Hack is much more than that, the language brings features that are normally found in statically typed languages to the dynamically typed world of PHP.

He focuses in on the static typing functionality of Hack a bit more and includes an example of PHP code where Hack would catch the type shifting. He also briefly mentions some of the other features including built-in collections, traits, generics and asynchronous programming.

The Duck is a Lie
Jun 27, 2012 @ 09:55:22

In this recent post to DZone.com Giorgio Sironi looks at duck typing and compares it in a few different languages (PHP, Ruby and Java). "Duck typing" is where the methods/functions define the structure or common interface rather than being functional.

What follows is my experience with Java, PHP and Ruby. I mainly use PHP as a dynamic language that supports duck typing but also the definition of Java-like interfaces, but does not force any of the two approaches as you can define interfaces whose method arguments accept any variable or not using interfaces at all. Is duck typing that a revolution?

He shares some of the common misconceptions he's seen including the idea that duck typing can help completely different objects work together and that, sometimes, despite naming conventions, functionality was intended to be different. He shows how even interfaces in PHP can be implemented loosely and the "acts as" and "single callback" architecture ideas.

Pim Elshoff's Blog:
In favour of typing
Apr 25, 2012 @ 13:57:38

Pim Elshoff has a new post to his blog that shares his preference on typing (keystrokes, not variables) in applications (hint: he likes it):

We sometimes conceive of ideas that are arduous to express in code. Like persisting data, or some other uncommon task (sarcasm). It's not difficult, but it takes a lot of keystrokes to write. Being problem solvers, we find it difficult doing this kind of manual labour, especially when machines can do it for us. Still, I would like to take this opportunity to say that typing rocks and solutions that save typing suck.

He talks about the abstraction that frameworks provide (less typing, more work) and and some of the "magic" that comes with them. He gives specific examples of some of his pervious experience with frameworks (including some pains with Symfony2) and how some of the magic he's seen is easy to write but hard to read.

Evert Pot's Blog:
Numeric string comparison in PHP
Apr 26, 2011 @ 09:23:47

In this new post to his blog Evert Pot reminds you (the PHP developer) about the loose and strict typing checks that you need to do when checking the values of your variables and never just assume. PHP's loose typing tendencies can cause issues if you're not paying attention.

As long as you make sure you always use strict checking (=== and !==) where you can, and fall back to the loose checks when you must. As a PHP developer, I think it's very important to understand and memorize exactly how these work, whether you're writing new code, or maintaining existing code.

He points out a specific example of some code that seems counter-intuitive when you compare how it reads and how it actually works (strings converted to floats and evaluated)

The moral is: always do strict checks when you are able to.

Giorgio Sironi's Blog:
Java versus PHP
Apr 16, 2010 @ 10:55:19

In a new post to his blog Giorgio Sironi has a (more balanced) comparison of Java versus PHP that them on topics like how they handle typing and their execution models.

If you exclude C and its child C++, the most popular programming languages in the world are Java and PHP, which power most of the dynamic web. I have working experience with PHP and for academical purposes I am deepening my knowledge of Java, thus I'd like to point out similarities and key differences between these two languages. Every language has its pros and cons, so there's no absolute winner here.

He briefly covers their history, java's static versus PHP's dynamic typing, how they both handle objects, their execution plans and how easy they are to deploy when it comes to general applications.

Static/Dynamic typing sweet spot
Oct 08, 2008 @ 10:24:28

In a new post today Jani Hartikainen takes a look at one of the things that makes PHP both powerful and unpredictable at times - its variable typing, static versus dynamic.

It seems that PHP has moved a bit towards static typing, and languages like C# seem to be implementing some dynamic features. Are we going towards a "mixed" language with static and dynamic typing? What's the "sweet spot" between completely static (like C++) and completely dynamic typing (like Python)?

He compares the benefits of static and dynamic, and a particular place where PHP falls a bit flat - type hinting in certain situations. He agrees, though, that dynamic typing is "the way to go" since it gives the developer the flexibility they might need for more "typing tricks" in their apps. Oh, and "duck typing"...

Matthew Turland's Blog:
The Yin and Yang of Typing
Feb 01, 2008 @ 11:58:00

A little while back Matthew Turland posted about something that some developers moving over to PHP from more strict languages have an issue with - variable typing - and how its evolved in languages over time.

Without a little background in programming languages or computer science in general, it's entirely possible that typing systems are not something that have crossed your mind. I thought I'd take a blog entry to share some of my thoughts on how it’s affecting the creation and evolution of languages.

He walks through history a bit, mentioning C, Java, Python and PHP and how they differ in their default type handling. He especially focuses on the "blurred line" between strong and weak typing and how some if offers special features to the language that uses the method.
