You should try this if you want to do this in the same way, you were doing:

<?php
$blog_owner='jean'; 

echo '<span onclick="
var blog_owner=\"'.$blog_owner.'\";
alert(blog_owner); " class="comment_r_button">Reply</span>';

?>

However, you can ignore the variable & can write it as:

<?php
$blog_owner='jean'; 

echo '<span onclick="alert(\"'.$blog_owner.'\"); " class="comment_r_button">Reply</span>';
?>

<!DOCTYPE html>
<html>
<head>
  <script>
    function showBlogOwner(){
      var blog_owner = 'jean';
      alert(blog_owner);
    }
  </script>
  <meta charset="utf-8">

</head>
<body>
  <span onclick="showBlogOwner()" class="comment_r_button">Reply</span>
</body>
</html>

There is no need to create var to alert it try this. 

echo '<span onclick="alert(' . $blog_owner . ')" class="comment_r_button">Reply</span>';
