//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
