如何根据语言更改占位符文本

Hello I am newbie and I would like to ask how is it possible to change the placeholder depend on language?. I have a multilingual wordpress site and I wrote this code on a .php file :

<form class="search" id="searchform" action="<?php echo home_url(); ?>/" method="get">
   <fieldset>
       <span class="text"><input name="s" id="s" type="text" value="" placeholder="<?php echo __('Search', 'alora'); ?>" />
       </span>
   </fieldset>
</form> `

I also tried this:

<form class="search" id="searchform" action="<?php echo home_url(); ?>/" method="get">
   <fieldset>
      if (get_locale() == "en_US") {
         <span class="text"><input name="s" id="s" type="text" value="" placeholder="<?php echo __('Search', 'alora'); ?>" />
         </span>
         }
      else {
         <span class="text"><input name="s" id="s" type="text" value="" placeholder="<?php echo __('Search_el', 'alora'); ?>" />
         </span>
         }
    </fieldset>
</form> 

But with no luck. Can anyone please help me?.

I also read this post Change text depending on language, but I couldn't figure it out.

<?php echo _e('Search_el', 'alora'); ?>" />

Please use this..

if above code not working than use..

printf(__('Search_el', 'alora'));
