PHP將中文翻譯成拼音

從i18n-ascii.txt文件中讀取數據，進行翻譯，代碼如下：

    /**
     *  Generate project alias by project name
     */
    private function _generateAlias($name, $projectId) {
        $file = dirname(__FILE__) . DIRECTORY_SEPARATOR . 'i18n-ascii.txt';
        $separator = '-';

        // Read translation file
        if (file_exists($file)) {
            $translations = parse_ini_file($file);
        }

        // Translate name to ASCII
        if (!empty($translations)) {
            $name = strtr($name, $translations);
        }

        // Replace white space with the separator.
        $name = preg_replace('/\s+/', $separator, $name);

        // Turn to lower case
        $name = strtolower($name);

        // Check whether the name is exist
        if ($projectId) {
            $sql = 'SELECT url_alias FROM project WHERE id <> \'' . $projectId . '\' AND url_alias LIKE \'' . $name . '%\'';
        } else {
            $sql = 'SELECT url_alias FROM project WHERE url_alias LIKE \'' . $name . '%\'';
        }
        $aliases = Yii::app()->db->createCommand($sql)->queryAll();

        // If the alias is exist
        if (count($aliases) > 0) {
            $start = strlen($name);
            $subfixes = array();
            foreach ($aliases as $alias) {
                $subfix = $alias['url_alias'];
                if ($subfix == $name) {
                    $subfixes[] = '0';
                } else if (substr($subfix, $start, 1) == $separator) {
                    $subfix = substr($subfix, $start + 1);
                    if (is_numeric($subfix)) {
                        $subfixes[] = $subfix;
                    }
                }
            }
            if (count($subfixes) > 0) {
                $subfix = max($subfixes) + 1;
                $name = $name . $separator . $subfix;
            }
        }

        return $name;
    }
