PHP注册表不起作用 - 现在固定

Question

EDIT: THIS IS NOW FIXED & DOES NOT NEED ANY MORE ANSWERING.

Answer 1

your conditions are not properly closed, there is no "if" for this "else"

else {
        echo '<div class="alert alert-warning">That Email Already Exist.</div>';
    }
}

You should look for a PHP editor that helps you to format the code properly and find inconsistences (MS Code maybe? or Brackets?).
