Thats a little vague. Nested if's are just if statments inside each other so you would use them anywhere you need to split information down further. As an example...

 

Let's say we have a group of people and we wanted to bahave differently dependent on gender and marital status.

 

$name = "john";
$gender = "male";
$married = TRUE;

if($gender == "male") {
   if($married) {
      echo "Hello 'Condemned Man' $name";
   } else {
      echo "Hello Mr $name";
   }
} elseif($gender == "female") {
   if($married) {
      echo "Hello Mrs $name";
   } else {
      echo "Hello Miss $name";
   }
} else {
  "Hello Ladyboy $name";
}
