simple delete from array?

[Westcoast Sheri]

Any way to do a simple delete from array?

In other words, what would be the *easiest* (and fastest php runtime)
way to delete "banana" from the following array:

$my_array = array(
"apple",
"banana",
"grape",
"lime"
);

.....so that $my_array will now be:

$my_array = array(
"apple",
"grape",
"lime"
);

if you know the position (offset) of the element you want to delete
(in your example above, 'banana' is element 1 in the array):

array_splice($m y_array, 1, 1);

if not:

array_splice($m y_array, array_search('b anana', $my_array), 1);

if you are using associative arrays you can use unset:

$my_array = array(
'apple' => 1
'banana' => 2,
'grape' => 3,
'lime' => 4
);
unset($my_array['banana']);

this appears not to work with non-associative arrays.

Use a second array and for each in the first array either insert it
into the second array or not depending on your criteria.
