I do admit, yes, am rocking with MongoDB

 

The simple adapter:

SVN Setting eol-style

November 25, 2011 by kim

When using SVN in team coding, we need the unified end of file descriptor for all the repository files. Usually it’s LF(line-feed) which is the end of line char under linux.

 

SVN has supportted this feature as svn:eof-style option, making all as easy as below.

 

(1) Config file:

 

For Win (usually):
C:\Documents and Settings\Administrator\Application Data\Subversion\config :

 

For Linux (usually):
~/.subversion/config

 

(2) Add option list:

 

*.php = svn:eol-style=LF
*.phtml = svn:eol-style=LF
*.pl = svn:eol-style=LF;svn:executable=*
*.c = svn:eol-style=LF
*.cpp = svn:eol-style=LF
*.h = svn:keywords=Author Date Id Rev URL;svn:eol-style=LF
*.dsp = svn:eol-style=CRLF
*.dsw = svn:eol-style=CRLF
*.sh = svn:eol-style=LF;svn:executable=*
*.txt = svn:eol-style=LF;svn:keywords=Author Date Id Rev URL;
*.png = svn:mime-type=image/png
*.jpg = svn:mime-type=image/jpeg
*.js = svn:eol-style=LF
*.css = svn:eol-style=LF
*.html = svn:eol-style=LF
Makefile = svn:eol-style=LF

Cron Job Script in Zend Framework

July 27, 2011 by kim

To create a cron job script in Zend Framework, we just need 3 steps :

 

1. Create a new directory called “scripts” which is the storage of all the scripts(.sh, .php, etc.).

 

2. Copy public/index.php into “scripts” and rename it to your cron job name, for example “cron.php”.

 

 

3. Modify the code. Instead running the application, we now only do the bootstrap:

 

// Define path to application directory
defined('APPLICATION_PATH')
    || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));

// Define application environment
defined('APPLICATION_ENV')
    || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'development'));

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH . '/../library'),
    get_include_path(),
)));

date_default_timezone_set('America/New_York');

/** Zend_Application */
require_once 'Zend/Application.php';

// Create application, bootstrap, and run
$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH . '/configs/application.ini'
);

// only do bootstrap
//$application->bootstrap()->run();
$application->bootstrap();

// get the options and run CLI
try {
    $opts = new Zend_Console_Getopt('abc:');
    if (isset($opts->a)) {
        echo "I got the a option.\n";
    }
    if (isset($opts->b)) {
        echo "I got the b option.\n";
    }
    if (isset($opts->c)) {
        echo "I got the c option.\n";
    }
} catch (Zend_Console_Getopt_Exception $e) {
    echo $e->getUsageMessage();
    exit;
} catch (exception $e) {
    echo $e->getMessage();
    exit;
}

Setup ZFDebug for Debuging your Zend Framework Project

July 2, 2011 by kim

“ZFDebug is a plugin for the Zend Framework for PHP5, providing useful debug information displayed in a small bar at the bottom of every page.”

 

We just need two steps to setup ZFDebug:

 

1. Download it from https://github.com/jokkedk/ZFDebug, place it inside library just next to Zend Framework

 

 

2. Modify application/Bootstrap.php to add initialized function:

 

/**
 * include ZFDebug console in development environment
 */
protected function _initZFDebug()
{
    // normally only section [development] has the "zfdebug" option
    if ($this->getOption('zfdebug')) {
        // namespace "ZFDebug" for autoloader
        $autoloader = Zend_Loader_Autoloader::getInstance();
        $autoloader->registerNamespace('ZFDebug');

        // initialize front controller
        $this->bootstrap('FrontController');
        $front = $this->getResource('FrontController');

        // enable zfdebug options
        $options = array('plugins' => array(
            'Variables',
            'Memory',
            'Time',
            'Registry',
            'Exception',
        ));

        // add caching backend option if specified
        if ($this->hasPluginResource('cache')) {
            $this->bootstrap('cache');
            $cache = $this->getPluginResource('cache')->getDbAdapter();
            $options['plugins']['Cache']['backend'] = $cache->getBackend();
        }

        // add db option if specified
        if ($this->hasPluginResource('db')) {
            $this->bootstrap('db');
            $db = $this->getPluginResource('db')->getDbAdapter();
            $options['plugins']['Database']['adapter'] = $db;
        }

        // register ZFDebug with front controller
        $zfdebug = new ZFDebug_Controller_Plugin_Debug($options);
        $front->registerPlugin($zfdebug);
    }
}

 

And that’s all, now you should see a debug bar just at the bottom of your project like this:

Create Multiple Websites with One Shared Library by Zend Framework

June 23, 2011 by kim

When we try to generate the project by Zend_Tool by command line like this:

$ zf create project myProject

 

We get a standard structure which is recommended by Zend Framework:

It works very fine as “one” website project. But how about if we want to create multiple websites without rewriting too many code?
The main idea is to share as much as possible the libraries meanwhile keeping independence of each website, especially the designs/templates/publics.

 

 

Here is one simple way which makes the minimal modifications and satisfy our needs:

 

(1) Move the folder “library” out of the project.

 

(2) Modify /public/index.php as below to make sure the library/ is in include paths:

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
    //realpath(APPLICATION_PATH . '/../library'),
    realpath(APPLICATION_PATH . '/../../library'),
    get_include_path(),
)));

 

(3) Modify /application/config/application.ini :

;includePaths.library = APPLICATION_PATH "/../library"
includePaths.library = APPLICATION_PATH "/../../library"

 

 

Assume that we have project1, project2 and project3, all applied the same treatment. And finally the websites could like this:

In the picture above, assume that our global namespace is “Projlib”. We have a model class Projlib/Model/Foo.php

class Projlib_Model_Foo
{
    // ...
}

 

Then we can just put this configuration inside application/configs/application.ini to make it autoloaded:

; --- my library prefix -----------------------------------------------------------------
autoloadernamespaces.global = "Projlib_"

 
 
And that’s all! Enjoy it.

Replace Accents by Normal Unaccented in PHP

May 15, 2011 by kim

Sometimes we need the string to only contain unaccented characters, for example urls, xml, filename etc.

 

Expecially before PHP6, You may think of function setlocale() and iconv(), but they are evil…

 

If you’re writing code for yourself, to be used on a server you control, locales could be made to work if your server has locales installed which support UTF-8. That would mean functions like strtolower behave correctly.

But this is no use if you’re writing applications which will be installed by third parties (like these for example) because it’s system specific (it’s not even just OS specific). If the default system locale does not support UTF-8, in theory your application could change the locale “on the fly” using setlocale but in practice that requires two things; that there is a locale available on the system which supports UTF-8 (not guaranteed) and that the correct locale identifier string can be found (there a definately differences between Windows and *Nix locale identifiers and even amongst the Unixes believe there are variations e.g. FreeBSD). What’s more, you can’t rely on users to be able to change the locale correctly to suit your applications needs – on a shared host they probably won’t be able to change the locale for the user that Apache is running with. Bottom line - locales are not the way to go for applications intended to be “write once, run anywhere”.
– http://www.phpwact.org/php/i18n/utf-8

 

Here is just the function to replace accented characters by normal english letters.

 

It contain a long list of characters matching table and use strstr() to replace accents.

 

function replaceAccents($str)
{
    $normalizeChars = array(
        "\xC3\x80" => "A", "\xC3\x81" => "A", "\xC3\x82" => "A", "\xC3\x83" => "A", "\xC3\x84" => "A",
