What is the Zend Framework?

• PHP 5 class library for web development

• Free, open source, BSD license (like PHP)

• +150,000 lines of code

• Emphasis on quality: 90%+ unit test coverage

• Solutions are “extremely simple” – solving the 80% usage case, and allowing for extensibility

• +200,000 downloads

• http://framework.zend.com/

Directory layout

/Zend/Zend/Locale.php/Zend/Locale/Zend/Locale/Format.php…

A component is always a base class and all subclasses in it’s same named directory. ..

This way single components can be used without installing the complete framework…


Page 11

Minimum requirements

• Some Minimum requirements

PHP 5.1.4 Webserver Standard installation commonly no additional extensions needed

• That’s all…


Page 12

A simple example 1/4

• A simple example – Localisation:

<?php require_once ‘Zend/Locale.php’; $locale = new Zend_Locale(); print $locale->toString();


Page 13


• Each class can be used alone:


Requiring the file is enough…Each component knows which other components it

has to load


Page 14


• Location of the ZF components:


All components are in the same directory.


Page 15


• The result: our users language


The visiting users language…


Page 16

Localisation

• Possibilities of Zend_Locale

Get the client users languages Get localized data Base localisation class for ZF Locale aware formating of numbers, dates and times

• Example1

• Example2


Page 17

Localized data

• Localized and translated data:

Translation for all languages Translation for all scripts Translation for countries and territories Calendar formats Month- and Day names Standard formats for Date and Time Currency name, signs and formats Characters used in this language Yes and no strings …


Page 18

Locale aware formating rules

• Zend_Locale_Format Converting from one script to another Normalizing of numbers (12,345.45 -> 12345.45) Localizing of numbers (12345.45 -> 12,345.45) Checking if a localized number is valid Normalizing date & time inputs Checking if a localized date or time input is valid


Page 19

Script conversion

• From european digits to arabic digits and visa versa

<?phprequire_once ‘Zend/Locale.php’;$number = “12345”;$converted = Zend_Locale_Format::convertNumerals($number, ‘Latn’, ‘Arab’);$european = Zend_Locale_Format::convertNumerals($converted, ‘Arab’, ‘Latn’);

• Example3


Page 20

Number normalization

• Normalizing numbers

<?phprequire_once ‘Zend/Locale.php’;$number = “12.345,67”;$normal = Zend_Locale_Format::getNumber($number);

• Example4


Page 21

Number localization

• Localizing numbers

<?phprequire_once ‘Zend/Locale.php’;$number = 12345.67;$normal = Zend_Locale_Format::toNumber($number);

• Example5

• Example8


Page 22

Multilingual applications

• Making applications running worldwide

Translating output Format of date and time Format of numbers Format of currencies Knowing allowed characters of a language


Page 23

Translation

• Gettext… the old way

• <?phpbindtextdomain(‘domain’, ‘path’);textdomain(‘domain’);

print gettext(‘my translation’);

• Fixed directory layout /path/LC_ALL/locale/

• Needs an extension to work

• Complicated for people unfamiliar to GNUs gettext


Page 24

Zend_Translate

• Gettext… with Zend_Translate

• <?phprequire_once ‘Zend/Translate.php’; // within bootstrap file

$tr = new Zend_Translate(AN_ARRAY, ‘Path/to/myfile.mo’, ‘de’);print $tr->_(‘my translation’);

• No fixed directory layout

• No extension needed

• Same API for all sources


Page 25

Zend_Translate sources

• Zend_Translate sources One API for all sources Supported sources are:

• Array• Csv• Gettext• Qt• Tmx• Xliff

More to come (SQL, XmlTm, …)


Page 26

Switching sources

• Changing sources ? No problem…


$tr = new Zend_Translate(AN_CSV, ‘Path/to/myfile.csv’, ‘de’);print $tr->_(‘my translation’);


$tr = new Zend_Translate(AN_GETTEXT, ‘Path/to/myfile.mo’, ‘de’);print $tr->_(‘my translation’);

• Just one small change, same API


Page 27

Conditional translating

• Is a string translateable ?


$tr = new Zend_Translate(AN_CSV, ‘Path/to/myfile.csv’, ‘de’);if ($tr->isTranslated(‘my translation’)) {

// do something} else {

// no translation, do something else}

• Not possible with php


Page 28

Allowed characters

• Verifying input… but localized ?

• <?phprequire_once ‘Zend/Locale.php’; // within bootstrap file

$tr = new Zend_Locale();$de = $tr->getTranslationList(‘characters’, ‘de’);$fr = $tr->getTranslationList(‘characters’, ‘fr’);

• For more than 128 languages

• Example6


Page 29

Language selectbox

• Creating a localized selectbox for languages ?


$tr = new Zend_Locale();$de = $tr->getTranslationList(‘language’);foreach ($de as $key => $value) {

$fr = $tr->getTranslationList(‘language’, $key);print $fr[$key];

}

• Example7


Page 30

Yes or No

• How to realize a yes-no for every language ?


$tr = new Zend_Locale();$de = $tr->getQuestion();

• Example9


Page 31

Normalizing dates

• Monthnames / Daynames


$date = “12.März.2007 20:15:00”;$tr = new Zend_Locale_Format::getDate($date, ‘de’);print_r($tr);

• Example10


Page 32

Working with dates

• Zend_Date

One class Handles all meanings (date, time, parts, sun…) Simple API Easy handling ISO Standard also PHP’s GNU supported Knows more than 50 standard represenations Unlimited (more than 64bit) dates supported


Page 33

Working with dates 2

• Capabilities

Computing dates Get sunset / sunrise for cities Easy changing with ISO ( dd.MM.yyyy HH:mm:ss a ) Supports different standards

( ISO, GNU, RFC2822 (mail), W3C, RSS, Cookies…)


Page 34

Date maths

• Computing dates

Normalized Localized Added / Substracted Checked (earlier, later, equal Splitted Converted …


Page 35

Date example

• Example11

$date = new Zend_Date(‘20070414T122050’, Zend_Date::ISO_8601);

$date->addMonth(2);$date->subYear(6);

If ($date->isLeapYear()) { // LeapYear} else { // NO LeapYear}


Page 36

Checking dates

• Check if a date is a date

If ( Zend_Date::isDate(’14. April. 2007 10:20:55’))

• Example12

• Compare parts

If ( $date->compareWeekday(2))

• Example13


Page 37

Stay up

• Calculating sunset / sunrise

With php… complicated With Zend_Date… just know your city

$city = Zend_Date_Cities::City(‘Amsterdam’);$date = new Zend_Date();$uptime = $date->getSunrise($city)

• Easy handling

• Easy extending – 80% use case

• High quality

• Growing fast
