php - Use variable outside foreach loop

Solution:

As long as you are inside theif($result->rowCount() != 0) {, you know a$result[0] exists and, based on the SQL, all the$result have the samecat_title, so you can do this:

function get_cat_posts($cat_id, $conn)
{
   $data = $conn->query("SELECT blog_item.id, blog_item.title, blog_item.category_id, blog_item.posted_on, blog_item.content, menu_item.cat_title, menu_item.cat_id FROM blog_item INNER JOIN menu_item ON blog_item.category_id = menu_item.cat_id WHERE menu_item.cat_id= $cat_id");
   if($data->rowCount() != 0) {
       $result = $data->fetchAll(PDO::FETCH_ASSOC);
       echo $result[0]['cat_title']; // format as you want
       foreach($result as $row) {              
                               echo '<hr>';
                               echo '<a href="post_cat_template.php/? category=' .$row['cat_id'] . '?post_id=' .$row['id'] . '">' . $row['title'] . '</a> - <em>' . $row['posted_on'] . '</em>';
                               echo '<hr>';
               } 
   }
   else { echo "no posts in this category";}
}
