Adding a code to WordPress header based on local language into functions.php

问题

I have to add a Javascript code to a WordPress header based on the current language used by the website. We use WPML string translation. I want to write a function like this:

function add_customcode_header(){
?>
if(ICL_LANGUAGE_CODE == 'ru')
  {
    <script>
code 1
</script>
} 
  else
  {
<script>
code 2
</script>
  }
}
<?php
add_action('wp_head', 'add_customcode_header');

This function should place the script with code 1 contents if the website language parameter is set to 'ru' and IF the language parameter is any other, it should add the code 2 for other languages

The magic question is - will this function work properly?

UPDATE:

The proper solution that works:

function add_customcode_header(){
if(ICL_LANGUAGE_CODE == 'ru')
  {
    echo '<script>
              code 1
          </script>';
} 
  else
  {
    echo '<script>
              code 2
          </script>';
  }
}
add_action('wp_head', 'add_customcode_header');

Your overall idea should work fine, however, in the example you posted, there were some syntax errors.

function add_customcode_header(){
if(ICL_LANGUAGE_CODE == 'ru')
  {
    echo '<script>
              code 1
          </script>';
} 
  else
  {
    echo '<script>
              code 2
          </script>';
  }
}
add_action('wp_head', 'add_customcode_header');

    function add_customcode_header(){

    if(ICL_LANGUAGE_CODE == 'ru')?>

        <script>
    code 1
    </script>
    <?php
      else ?>
    <script>
    code 2
    </script>
<?php
    }  
    add_action('wp_head', 'add_customcode_header');

Should both be syntactically correct, and it really just matters what you're more comfortable with.
