php isset , empty , null , = ""

<div>
    <h2>How many services do you need ?</h2>
    <form action="<?php $_SERVER['PHP_SELF']?>" method="GET" name="fServ">
    <input type="number" name="numServ" />
    <input type="submit" value="SEND">
    </form>
<div>
    <?php

    if(isset($_GET['numServ'])){
        echo "We need ".$_GET['numServ']." services";
    }
    if(!isset($_GET['numServ'])){
        echo "We don't have any services yet.";
    }
    else if($_GET['numServ']=""){
        echo "Please put in a number";
    }

Say you have this following form, it works if I put in a number or access the form on first load. However I could never on the last if statement : ( Put in a number )

I have tried with POST and GET methods. GET methods will show : .php?numServ=

I tried : 

if((isset($_POST['numServ']) && $_POST['numServ']=="")

if(empty($_POST['numServ']))

if(is_null($_POST['numServ']))

if($_POST['numServ'] == "")

if($_POST['numServ'] == null)

I stil can't fall in the last condition.

one thing I can see in code 

if($_GET['numServ']="")

You are using assignment operator here Please replace it with 

if($_GET['numServ']=="")

and you should be fine with get method
