You need to use isset with ternary operator to avoid error

<b>Civil Status: </b>
<select class="controler-1" name="reg_civil_status">
    <?php 
        $reg_civil_status = isset($personal_info['reg_civil_status']) ? $personal_info['reg_civil_status'] : "";
        $posted_reg_civil_status = isset($_POST['reg_civil_status']) ? $_POST['reg_civil_status'] : "";

        foreach($civil_status_opt as $civil_status_opt){
            if($reg_civil_status == $civil_status_opt || $posted_reg_civil_status == $civil_status_opt) {
                echo "<option selected='selected' value='$civil_status_opt'>$civil_status_opt</option>";
            }
            else {
                echo "<option value='$civil_status_opt'>$civil_status_opt</option>";
            }
        }
    ?>
</select>
