************************************************************************************************************** * * * Class name: class.Language.php * * Author: Deyby Vasquez * * E-mail: * * Version: 1.0 * * Licence: MIT Licence * * Web site: * * * ************************************************************************************************************** ************************************************************************************************************** WHAT DOES class.Language.php DO? ************************************************************************************************************** Allows to implement multiple languages in a Web site developed in PHP language. This class detects the visiting client language and displays the content in the correct language, if the language is not supported it displays the content in a default language. It's easy to implement a selecting language system e.g. a form, in order that users can select the language. Just configure the languages into an associative array file. ************************************************************************************************************** INSTALLATION ************************************************************************************************************** 1. Unzip the files and upload the unziped files to the root directory. 2. That's it just test it e.g: http://localhost/nameOfUnzippedFile or http://yourdomain/nameOfUnzippedFile ************************************************************************************************************** CREATING YOUR OWN PAGES FROM 0 ************************************************************************************************************** 1. Unzip the files and upload the class.language.php file to the root directory. 2. Create the associative array with the content to the page for each language you require e.g: <?php /* English language configuration */ $lang = array ( /* title page */ 'title' => "Example page in english", /* Content items */ 'welcome' => "Hello world", 'language' => "The language page is in English", 'en' => "English", 'es' => "Spanish", 'fr' => "French", ); ?> 3. Save it with two language first letters and conf extension e.g. en.conf into a languages directory. 4. Set a default language variable e.g $DEFAULT_LANGUAGE = 'en'; and languages directory path e.g $LANGUAGE_DIR = '../languages'; into a configuration file or in the pages. 5. Include the class in the pages that you're going to display multiple languages e.g: require_once ("class.languages.php"); 6. instantiating the class and apply the getLanguage method e.g: $language = new Language(); $lang = $language->getLanguage(@$_POST['lang']); 7. That's it just you have to display the content in your pages e.g: echo $lang['welcome']; *************************************************************************************************************** CREATING SELECTING SYSTEM (Optional) FROM 0 *************************************************************************************************************** 1. Create a system e.g: A form <form name="language" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <select onchange = "document.language.submit()" name="lang"> <option selected="selected"><?php echo $lang['select-language']; ?></option> <option value="en"><?php echo $lang['en']; ?></option> <option value="es"><?php echo $lang['es']; ?></option> <option value="fr"><?php echo $lang['fr']; ?></option> </select> </form> 2. You can use both methods POST or GET. 3. Be assure to set a variable name for the select item of the form e.g: <select onchange = "document.language.submit()" name="lang"> 4. The parameter that you pass to getLanguage method varies depending on method form e.g: If you use method="post" set $lang = $language->getLanguage(@$_POST['lang']); If you use method="get" set $lang = $language->getLanguage(@$_GET['lang']); 5. That's it ...! *************************************************************************************************************** MORE EXAMPLES *************************************************************************************************************** class.Language.php with Smarty you can access to a Spanish video and you can download the example code for free from: class.Language.php using a selecting language system, Spanish video and example code from: class.Language.php simple configuration, Spanish video and example code from: *************************************************************************************************************** NOTE *************************************************************************************************************** All examples acompaning this class must be uploaded to the root directory. *************************************************************************************************************** THANKS FOR USING IT ***************************************************************************************************************
