This is the code I have currently –

<script>
     jQuery(document).ready(function($){
        if (jQuery('body.default, body.alternative').length) {
               twitterFetcher.fetch('<?php echo $redux_demo['divider-twitter-id']; ?>', 'twitter-fetcher-tweet', 1, true, false);
        };
     });
</script>

Many thanks for any tips

  1. Try to use:

    <?php echo $redux_demo["divider-twitter-id"]; ?>

    instead of:

    <?php echo $redux_demo['divider-twitter-id']; ?>

    You need to wrap divider-twitter-id in double quotes, not single quote here.

  2. To answer the question of ‘adding js into a PHP file’, You need to echo it:

    <?php
 echo "<script>
  jQuery(document).ready(function($){
     if (jQuery('body.default, body.alternative').length) {
        twitterFetcher.fetch('" . $redux_demo['divider-twitter-id'] . "', 'twitter-fetcher-tweet', 1, true, false);
    };
  });
 </script>";
?>

    But to accomplish what you’re trying to do, put in functions.php:

    add_action('wp_enqueue_scripts', 'theme_scripts');

function theme_scripts() {
  if (!is_admin()) {  
    wp_enqueue_script( 'twitter-fetcher',  THEME_URL . '/js/twitter-fetcher.php?twitterId=' . $redux_demo['divider-twitter-id']);
  }
}

    Then in in wp-content/theme/js/twitter-fetcher.php,

    <?php
// Sets the proper content type for javascript
header("Content-type: application/javascript");
?>
jQuery(document).ready(function($){
     if (jQuery('body.default, body.alternative').length) {
        twitterFetcher.fetch('<?php $_GET['twitterId']; ?>', 'twitter-fetcher-tweet', 1, true, false);
   };
});
