With the announcement of Zend Framework beta 1, I have updated my venerable tutorial to work with it!
Getting started with Zend Framework 2 (beta1), creates the same application as my ZF1 tutorial, so it should be very familiar, but this time, it's in the context of Zend Framework 2. As usual, it's a PDF too.
Please download it, try it out and let me know if you find any typos!
If you are attending my ZF2 tutorial at the PHPNW11 conference on Friday, I thought I'd remind you that you may find it useful to bring a laptop.
Ideally, your laptop should be set up with PHP 5.3 and MySQL and a working copy of my ZF1 tutorial. It would be a good idea to have a vhost set up on http://zf2tutorial.localhost or similar. Ability to create additional vhosts may come in handy. The PHP cli tool should also work as you'll need to run some php scripts from the command line.
I'm going to be covering ZF2's autoloader, dependency injector, event manager and then we'll go through the current Mvc prototype. We'll also be doing some exercises if we have time.
I'm looking forward to it and hope you are too!
I'm delighted to be able to announce that I'm speaking at the next Day Camp 4 Developers on 1st October.
Day Camp 4 Developers is a one-day online conference run by our friend Cal Evans and is now onto its 3rd outing. An online conference is one that you attend in your own home (or office!) which keeps the costs down considerably, so you have no excuse not to buy a ticket: just $40!
Day Camp 4 Developers is unusual in that it it concentrates on the "soft" skills that a developer needs in order to do their job well. The topic for this Day Camp is Project Management which is something that every developer should have knowledge about. Even if you aren't a project manager yourself, understanding what it is and why it helps is vital for your career development in any team based undertaking.
I'm talking on how we manage projects in my company. The idea is to give you an idea of the things that have to be done in order to take a proposal through to a live website as there's more to it than just writing the code. I've found that now that all of our team here understand the project management side of the job, the whole process goes much more smoothly and more profitably for everyone. Hopefully I'll be able to help you understand what your project managers are doing during their day too!
With OS X 10.7, Apple continues to ship PHP 5.3 with PEAR, GD and PDO_MYSQL out of the box. This is how to set it up from a clean install of 10.7.
Ensure that the following directories exist:
sudo mkdir /usr/local/include sudo mkdir /usr/local/bin sudo mkdir /usr/local/lib sudo mkdir -p /usr/local/man/man1
export PATH=~/bin:/usr/local/bin:/usr/local/mysql/bin:$PATH export EDITOR=vim
at top of file. (Note that we set EDITOR whilst we are here so that svn is happy!)
mysqladmin -u root password {new-password}
mysqladmin -u root -p{new-password} -h localhost password {new-password}
mysqladmin -u root -p{new-password} reload
Clear the history file by typing history -c so that {new-password} isn't in plain text on the disk.
error_reporting = E_ALL | E_STRICT display_errors = On html_errors = On extension_dir = "/usr/lib/php/extensions/no-debug-non-zts-20090626"
(I like to see my xdebug errors in bright orange!)
Also, change all instances of /var/mysql/mysql.sock to /tmp/mysql.sock
Can't have a PHP development environment without xdebug! Apple appears to agree as Lion ships with it.
xdebug.var_display_max_children = 999 xdebug.var_display_max_data = 99999 xdebug.var_display_max_depth = 100
(use with caution…)
We need PEAR! For some reason, it's not set up ready to on Lion, but the install phar file is here, so we just need to run it.
I assume that everyone needs these…
A couple of projects I work on use the PECL OAuth component:
[oauth] extension="/usr/lib/php/extensions/no-debug-non-zts-20090626/oauth.so"
This is useful! Follow the installation details by Michale Gracie here: http://michaelgracie.com/2011/07/21/plugging-mcrypt-into-php-on-mac-os-x-lion-10-7/)
It all works on this machine, anyway :)
If you'd rather use a packaged version, then these are two alternatives:
One thing that is different between Zend_Config_Xml and Zend_Config_Ini is that with Zend_Config_Xml you can pass in an XML string as the first parameter of the constructor and it will work. This doesn't work with Zend_Config_Ini as we use parse_ini_file() under the hood.
With PHP 5.3 however there is is a new function called parse_ini_string() which will allow us to load arbitrary ini string into Zend_Config objects. This can't go into Zend Framework 1 though due to our PHP 5.2.4 minimum version requirement.
As I needed this for a project, I extended Zend_Config_Ini to support this feature, which means simply overloading a single method
class App_Config_Ini extends Zend_Config_Ini { /** * Load the INI file from disk using parse_ini_file(). Use a private error * handler to convert any loading errors into a Zend_Config_Exception * * @param string $filename * @throws Zend_Config_Exception * @return array */ protected function _parseIniFile($filename) { set_error_handler(array($this, '_loadFileErrorHandler')); if (substr($filename, -4) == '.ini') { $iniArray = parse_ini_file($filename, true); } else { $iniArray = parse_ini_string($filename, true); } restore_error_handler(); // Check if there was a error while loading file if ($this->_loadFileErrorStr !== null) { /** * @see Zend_Config_Exception */ require_once 'Zend/Config/Exception.php'; throw new Zend_Config_Exception($this->_loadFileErrorStr); } return $iniArray; } }
The actual change is to see if the last 4 characters of the filename are ".ini" and if they aren't then use parse_ini_string() instead of parse_ini_file(). The rest of the code is just error handling.
This is one area where I really like it when a class implements methods that done just one thing.
