I have an array with indexes 0 to 4 and I want to delete an element of the
array if the index is equals 4. I want to delete the variable key and value.
What is the best way to do so?
foreach ($values as $key = $val){
if ($key == 0) {
//
}
if ($key == 3) {
//
}
if ($key == 4) {
//delete value
if (isset($values[4])
unset($values[4]);
Cheers,
David Grant

You may want to use array_key_exists instead of isset. isset will
return false in the value for the array is NULL. Basically isset will
tell you if there is a value set for the array key, whereas
array_key_exists will tell you if the key exists or not, which is
what you want.
