在php中搜索关联数组

Question

您好我有以下数组

Array
(
 [k1] => Array
        (
            [0] => banana
            [1] => mango
            [2] => orange
            [3] => orange
        )

    [k2] => Array
        (
            [0] => adaL
            [1] => ada
            [2] => dad
            [3] => dad
        )
)

现在我想删除像ORANGE这样的重复条目。我该怎么做？

Answer 1

$a = array_map('array_unique', $a);

Answer 2

您正在寻找array_unique

$k1 = array('banana', 'mango', 'orange', 'orange');
$k1 = array_unique($k1);

哪个会给你

array
  0 => string 'banana' (length=6)
  1 => string 'mango' (length=5)
  2 => string 'orange' (length=6)

Answer 3

foreach ($array as &$value) {
    $value = array_unique($value);
}
