Updating PHP 5.3 to 5.4 on Ubuntu 12.04

Shut up.. I know it is 2015, but sometimes we still have to manage servers from the past and do minor upgrades :)

$ sudo apt-get install python-software-properties $ sudo add-apt-repository ppa:ondrej/php5-oldstable $ sudo apt-get update $ sudo apt-get install php5

Desde el blog de Cpanel nos hacen un aviso importante: PHP 5.4 llega al final de su vida el 14 de Septiembre de 2015, y nos recomiendan actualizar a PHP 5.5 o superior.

Para ello, todos los que utilicéis en vuestro servidor cPanel/WHM tenéis que actualizar vuestra configuración utilizando EasyApache 3.32, en la que ya viene por defecto PHP 5.5 como versión recomendada.

In recent months I've been ultra busy working on our Z-Ray time-warping technology.  Now that it's out, I finally had a bit of free time to follow up and on what was clearly a very interesting topic for many in the PHP community - what kind of impact does PHPNG - a massive refactoring effort of the Zend Engine - have on PHP's performance.

The New PHP 5.4

There is a new version of PHP has been released in the couple of weeks or so. PHP 5.4. I would like to highlight a few features that I am excited about. Here is a link to some basic new features from php.net.

  Short Array Syntax

The new short array syntax is such a relief, I don’t know how many times I have typed array() and wished for the short Javascript like syntax. Maybe I’m just lazy but hey, that’s 5 extra characters that I’ve typed thousands of times, it adds up. Here are some examples:

1 2

$myArr = [1, 2, 3, 4 ,5]; $myArr = ['foo; => 'bar', 'test' => 99];

  Function Array Dereferencing

To go along with the the new short array syntax you can do function dereferencing, basically, if a function returns an array, you can access that array immediately instead of using a temp array.

1 2 3 4 5 6 7 8

$myStr = "apples,oranges,bananas";   // Old way $tmpArr = explode(",", $myStr); echo $tmpArr[1]; // Returns "oranges"   // New way echo explode(",", $myStr)[1]; // Returns "oranges"

  Class Member Access Upon Instantiation

In PHP 5.4 they have also added a feature that lets you call a method of a class upon instantiation.

1 2 3 4 5 6 7 8 9

class TestClass { public function __construct(){ /* We will leave this blank for now. */ } public function helloWorld(){ echo "Hello World!"; } }   // How to use it (new TestClass)->helloWorld(); // echos "Hello World"

  Traits

Traits are something I really want to touch on here. The exciting thing about traits is that now we can have multiple inheritance in PHP. Now, some people will say that multiple inheritance is dangerous, or a waste of time. However, one size does not fit all, there may arise situations that need multiple inheritance to make the code more optimal. There is a lot of information on traits, so please read up on the php.net site about them.

In a post in the near future I will give you an example of how to effectively use traits in a meaningful way.

Actualizar php en ubuntu 12.04

Si ya tienen instalado php 5.4 omitan el paso siguiente. Para ver su version de php escriban en el terminal:

php -v

Añadimos el nuevo origen:

sudo add-apt-repository ppa:ondrej/php5

Instalamos PHP 5.4:

sudo apt-get install php5

Pude que tras la instalación obtentas algún mensaje del tipo “… Unable to load dynamic library …”. Los mensajes se deben a que intenta cargar algún módulo que no se encuentra en la ruta indicada por el php.ini. Lo recomendado es revisarlo y ver que otros ficheros .ini carga mediante phpinfo(). En mi caso, tuve que reinstalar pdo para la conexion a mysql y xdebug para lo cual también necesite perl/pecl.

Ahora si procedemos a instalar php 5.5

La versión más reciente (es del 20 de Junio) es la 5.5.0. Si queremos compilarla o añadir un nuevo origen de Ondřej Surý para la esta versión:

Añadimos el nuevo origen:

sudo add-apt-repository ppa:ondrej/php5-experimental

Instalamos:

sudo apt-get install php5

Setting up a PHP 5.4 development environment with Homebrew on OS X

One of my favorite features of PHP 5.4 so far has been the server mode that it provides. Sure, traits are awesome and the fix for closures and $this is great, but being able to finally roll my own development environment, without Apache and vHosts is amazing. Normally the task of custom compiling PHP 5.4 would be a major pain, however with the help of the Homebrew project, it is a breeze.

Note: These instructions are intended for Mac OS X and were written using v10.7 (Lion) and v10.8 (Mountain Lion) as a testing platform.

1) Let's get started by Installing Homebrew

Note: For this step you will to need to have X-Code installed. If you do not already, go to the App Store and install it now. 

Per the instructions in the Homebrew installation wiki page:

Open a terminal and run the following:

/usr/bin/ruby -e "$(/usr/bin/curl -fsSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"

As the guide says: Read the script if you like. It is always a good idea to make sure something like this isn't going to do something malicious to your computer. Personally, I found it to be clean, but be your own judge. 

If You already have Homebrew installed, then be sure to update it as follows

brew update

2) Tap the homebrew-php formulas.

Run the following in your terminal window.

brew tap josegonzalez/homebrew-php

This will hook you up to a full repository of formulas for installing php 5.3 and php 5.4 extensions and addons. Everything from XDebug to Composer can be easily installed this way. For a full list of the recipes, checkout the formula list.

3) Install PHP 5.4

Run the following in your terminal window.

brew install php54

If you're using MySQL, try this install:

brew install php54 --with-mysql

This will take a few minutes to install. 

4) Setup your path

While the official docs say this is unnecessary to access php, if you want to be able to easily install things with PEAR, like php-unit, then you need to setup your path correctly. 

Add the following to your path, if you not sure where that is, then just edit the file ~/.bashrc

PATH="$(brew --prefix php54)/bin:$PATH"

This will make sure the PHP and all it's related binaries are easily found.

5) Running the local web server.

The web server can be accessed in a in a couple ways. The two most useful in my book are 

a) As a dumb directory server (serving files directly from the current path)

php -S localhost:8000

Now http://localhost:8000 will serve files in the current directory.

This is useful if you have a very simple application and you either have flat html that you're mocking up or just a simple php script that you're working with. For me, this is how I like to launch a quick JavaScript based project, without the overhead of setting up a vhost.

b) As a fully routed application stack

php -S localhost:8000 router.php

In this case the router should look something like this:

<?php // router.php if (preg_match('/\.(?:png|jpg|jpeg|gif)$/', $_SERVER["REQUEST_URI"])) {    return false;    // serve the requested resource as-is. } else {    // Load your application framework here...    echo "<p>Welcome to PHP</p>"; } ?>

Now all requests through http://localhost:8000/this-is-a-request will be routed through this router to decide what to do with it. If false is returned, then a matching file will bre returned instead.

To read more about PHP 5.4 web servers and the router file, read the full docs on php.net.
