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.

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 from array
}
}
Thanks!!!!!
