The "5" in your unset() example needs to refer to a key...assuming that $list is your array. You could use a foreach loop to get the array index for the items you want to remove and then use unset().

 

Note that you could also consider using array_flip() to swap the array's keys and values; unset the items you want to remove; and then flip the array back. More information about array_flip() can be found here:

http://php.net/manual/en/function.array-flip.php

 

Of course, you'll want to make sure there are no duplicate values in the array before using array_flip().

You can also use array_search() to look for a value in the array and if it exists it will return the associated key (or FALSE if not). You can then use the key to unset the index from the array.

if (($key = array_search($value_to_delete, $your_array)) !== false) {
  unset($your_array[$key]);
}
