Question

更清楚的是，默认语言general_lang.php中的这些行都不起作用：

$lang['general_welcome_message'] = 'Welcome, %s ( %s )';

或

$lang['general_welcome_message'] = 'Welcome, %1 ( %2 )';

我希望输出 Welcome, FirstName ( user_name ) 。

我在https://stackoverflow.com/a/10973668/315550跟随了第二个（不接受）回答。

我在视图中写的代码是：

<div id="welcome-box">
    <?php echo lang('general_welcome_message',
               $this->session->userdata('user_firstname'),
               $this->session->userdata('username')
               );
    ?>
</div>

我使用codeigniter 2。

您需要使用php的sprintf函数（http://php.net/manual/en/function.sprintf.php）

来自http://ellislab.com/forums/viewthread/145634/#749634的示例：

//in english
$lang['unread_messages'] = "You have %1$s unread messages, %2$s";

//in another language
$lang['unread_messages'] = "Hi %2$s, You have %1$s unread messages";

$message = sprintf($this->lang->line(‘unread_messages’), $number, $name);

我像这样扩展了Code CI_Lang类..

class MY_Lang extends CI_Lang {
    function line($line = '', $swap = null) {
        $loaded_line    = parent::line($line);
        // If swap if not given, just return the line from the language file (default codeigniter functionality.)
        if(!$swap) return $loaded_line;

        // If an array is given
        if (is_array($swap)) {
            // Explode on '%s'
            $exploded_line = explode('%s', $loaded_line);

            // Loop through each exploded line
            foreach ($exploded_line as $key => $value) {
                // Check if the $swap is set
                if(isset($swap[$key])) {
                    // Append the swap variables
                    $exploded_line[$key] .= $swap[$key];
                }
            }
            // Return the implode of $exploded_line with appended swap variables
            return implode('', $exploded_line);
        }
        // A string is given, just do a simple str_replace on the loaded line
        else {
            return str_replace('%s', $swap, $loaded_line);
        }
    }
}

即。在您的语言文件中：

$lang['foo'] = 'Thanks, %s. Your %s has been changed.'

无论你想使用它（控制器/视图等）

echo $this->lang->line('foo', array('Charlie', 'password'));

将产生

Thanks, Charlie. Your password has been changed.

这可以处理单个＆＃39;交换＆＃39;以及多个

它也不会打破现有的$this->lang->line来电。

如何在codeigniter语言行字符串中返回变量值？
