This function can be helpful in dual language forms when * users miss change keyboard language while they are entering data. * * If you wrote an Arabic sentence while your keyboard stays in English mode by * mistake, you will get a non-sense English text on your PC screen. In that case * you can use this class to make a kind of magic conversion to swap that odd text * by original Arabic sentence you meant when you type on your keyboard. * * Please note that magic conversion in the opposite direction (if you type English * sentences while your keyboard stays in Arabic mode) is also available in this * class, but it is not reliable as much as previous case because in Arabic keyboard * we have some keys provide a short-cut to type two chars in one click (those keys * include: b, B, G and T). * * Well, we try in this class to come over this issue by suppose that user used * optimum way by using short-cut keys when available instead of assemble chars * using stand alone keys, but if (s)he does not then you may have some typo chars * in converted text. * * Example: * <code> * include('./I18N/Arabic.php'); * $obj = new I18N_Arabic('KeySwap'); * * $str = "Hpf lk hgkhs hglj'vtdkK Hpf hg`dk dldg,k f;gdjil Ygn ,p]hkdm ..."; * * echo "<p><u><i>Before:</i></u><br />$str<br /><br />"; * * $text = $obj->swapEa($str); * * echo "<u><i>After:</i></u><br />$text<br /><br />"; * </code> * * @category I18N * @package I18N_Arabic * @author Khaled Al-Sham'aa <khaled@ar-php.org> * @copyright 2006-2016 Khaled Al-Sham'aa * * @license LGPL <http://www.gnu.org/licenses/lgpl.txt> * @link http://www.ar-php.org */ /** * This PHP class convert keyboard language programmatically (English - Arabic) * * @category I18N * @package I18N_Arabic * @author Khaled Al-Sham'aa <khaled@ar-php.org> * @copyright 2006-2016 Khaled Al-Sham'aa * * @license LGPL <http://www.gnu.org/licenses/lgpl.txt> * @link http://www.ar-php.org */ class I18N_Arabic_KeySwap { private $_transliteration = array();
