//using the foreach loop of php instead of a normal 
//for loop with the sizeof operator after unset is used. 

$values = array();

array_push($values,"lion");
array_push($values,"elephant");
array_push($values,"cheetah");
array_push($values,"wildebeest");

unset($values[2]);

//normal for loop thinks array size is three
//when sizoef function is used in conjunction
//the for loop.
for($i = 0;$i < sizeof($values); $i++) {
     echo "animals " . $values[$i]. "\n";
}
//prints
animals lion
animals elephant
animals

echo "\n";
//foreach prints the three values left properly
foreach($values as $animals) {
     echo "animal " . $animals. "\n";
}
//prints
animal lion
animal elephant
animal wildebeest

//simple but valid
