Removing non-unique PHP array values from unassociated array

Question

The following code:

$ids=['one','two','three','two','four'];
echo('<pre>'.print_r($ids,1).'</pre>');
$ids = array_unique($ids);
echo('<pre>'.print_r($ids,1).'</pre>');

produces the following:

Array
(
    [0] => one
    [1] => two
    [2] => three
    [3] => two
    [4] => four
)

Array
(
    [0] => one
    [1] => two
    [2] => three
    [4] => four
)

How do I preserve consecutive array indexes and produce the following:

Array
(
    [0] => one
    [1] => two
    [2] => three
    [3] => four
)

@PrototypeChain Thank you. Sorry, I searched and didn't find it. — user1032531, Jun 11 '16 at 19:22
PrototypeChain first commented that http://stackoverflow.com/questions/13596128/array-unique-and-then-renumbering-keys was a possible duplicate, but then deleted the comment. I don't agree that http://stackoverflow.com/questions/591094/how-do-you-reindex-an-array-in-php directly answered my question, but PrototypeChain's did. — user1032531, Jun 11 '16 at 20:10

You can use array_values.

Check out the manual: https://secure.php.net/manual/en/function.array-values.php
