下面的代碼刪除非唯一的PHP數組值:從非關聯數組
$ids=['one','two','three','two','four'];
echo('<pre>'.print_r($ids,1).'</pre>');
$ids = array_unique($ids);
echo('<pre>'.print_r($ids,1).'</pre>');
產生如下:
Array
(
[0] => one
[1] => two
[2] => three
[3] => two
[4] => four
)
Array
(
[0] => one
[1] => two
[2] => three
[4] => four
)
如何保持連續數組索引併產生如下:
Array
(
[0] => one
[1] => two
[2] => three
[3] => four
)
@PrototypeChain謝謝。對不起,我搜索了但沒有找到它。 – user1032531

PrototypeChain第一評論說http://stackoverflow.com/questions/13596128/array-unique-and-then-renumbering-keys是可能重複的,但後來刪除了評論。我不同意http://stackoverflow.com/questions/591094/how-do-you-reindex-an-array-in-php直接回答我的問題,但PrototypeChain的確。 – user1032531
