Tests only half the code and not the rest? - php

Question

Following code:
function personInfo($person)
{
$zipCode="12345";
if($zipCode!=54321)
{
$zipCode="12345";
$postal="World";
if($zipCode AND $postal < 1)
{
return "Wrong";
}
//Test stops here and do not continue???
}
$person->firstname="Mike";
$person->lastname="Wayne";
$person->address="Universe";
$person->zipCode="12345";
$person->mobile="123456789784512";
$person->password="GogoGO";
$person->socialSecurityNumber="1234567891234567";
return "OK";
}
I am not sure why it stops there since I want to test the code when it fails and when it's OK. I'm still learning so I would be much appreciated for all help!
Rest of the code (database & test) that connects to "function personInfo($person)":
function personInfo($person)
{
$this->db->autocommit(false);
$sql = "Select * from Postal Where ZipCode = '$person->zipCode'";
$result = $this->db->query($sql);
if($this->db->affected_rows!=1)
{
$sql = "Insert Into Postal (ZipCode, Postal) Values ('$person->zipCode','$person->postal')";
$result = $this->db->query($sql);
if($this->db->affected_rows < 1)
{
$this->db->rollback();
return "Wrong";
}
}
$sql .= "Update Person Set Firstname = '$person->firstname', Lastname = '$person->lastname',";
$sql .= " Address = '$person->address', ZipCode = '$person->zipCode',";
$sql .= " Mobile = '$person->mobile', Password ='$person->password'";
$sql .= " Where SocialSecurityNumber = '$person->socialSecurityNumber'";
$result = $this->db->query($sql);
$this->db->commit();
return "OK";
}
class personInfoTest extends PHPUnit_Framework_TestCase {
public function testPersonInfoWrong()
{
//arrange

$person=$zipCode;
