搜索关联数组在PHP

Question

您好我有如下阵列

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

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

现在我想删除喜欢橙色的重复条目。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); 

，这将给你

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); 
}
