Function within an if else

I have the following function in PHP

      function verificar_status(){
                global $db, $username, $usua, $ci_nro_cuenta, $monto, $nro_transf, $banco_emisor, $banco_destino, $fecha_transf, $status_pedido, $fecha_pedido, $status_pago, $fecha_aprobacion;

                $query = "SELECT * FROM pedidos  WHERE usuario = '$usua' AND status_pedido = 'ESPERANDO' ";
                $result = mysqli_query($db, $query);
                $rows =  mysqli_num_rows($result);
        if ($rows > 0){

            echo '<div class="alert alert-danger" role="alert"" >
                        <h3>
                LO SENTIMOS, USTED POSEE UN PEDIDO EN ESPERA        
                        </h3>
                    </div>';


        } else {

    verificar_pago_mes();

      echo ' <form autocomplete="off" class="was-validated" method="post" action= "pedidos.php">
         AQUI VA UN FORMULARIO
        </form>';
            } 

        }

//y por otra parte tengo la function 

function verificar_pago_mes() { 
    global $db, $username, $usua, $mes_de_pago_actual;

    $query = "SELECT * FROM pagos WHERE user = '$usua' AND mes_de_pago = '$mes_de_pago_actual'";
    $result = mysqli_query($db, $query);
    $rows =  mysqli_num_rows($result);

    if ($rows > 0){
        echo '<div class="alert alert-info" role="alert"" >
        <h3>'
.$mes_de_pago_actual .' Pagado      
        </h3>
    </div>';  


    } else {
        echo '<div class="alert alert-danger" role="alert"" >
        <h3>
Lo sentimos usted no ha efectuado el pago correspondiente a ' .$mes_de_pago_actual .'       
        </h3>
    </div>';
    exit;
    }

} 

My intention is that after analyzing verificar_pago_mes() can be executed within verificar_status() but it turns out that it does not show anything in the MODAL where verificar_status() is leaving if I comment the last line exit; if it shows the alert but it also shows the form.

Try doing if (verificar_pago_mes()=true) but logically indicate me error ..!

I appreciate any idea that allows me to implement the function correctly.
