you can pass php array into java script into html file

<script>
  var lat= <?php echo json_encode($lat); ?>
 var lng= <?php echo json_encode($lng); ?>
 var inf= <?php echo json_encode($inf); ?>
</script>

i see but you might be using php file then not HTML because you can't use php if the file format is html – Danyal Sandeelo Jun 30 '16 at 16:38
