Re: another simple array question

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.

if (isset($values[4])

    unset($values[4]);

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!!!!!
