我有以下内容:
( [0] => 3 [1] => 2 [2] => 12 [3] => 6 [4] => 8 [5] => 7 [6] => 9 [7] => 10 [8] => 5 [9] => 4 )
我想使用其中每个值作为关键:
( [0] => 7 [1] => 2 [2] => 10 [3] => 3 [4] => 5 [5] => 6 [6] => 11 [7] => 9 [8] => 4 [9] => 8 )
我试过这个:
foreach ($iOrder as $i)
{
$pOrder[$i] = $pOrder[$p];
$p++;
}
我明白了:
( [12] => 2 [10] => 6 [5] => 5 [4] => 7 )
第一个数组,$arr1,
( [0] => 3 [1] => 2 [2] => 12 [3] => 6 [4] => 8 [5] => 7 [6] => 9 [7] => 10 [ 8] => 5 [9] => 4 )
第二个数组,$arr2, ( [0] => 7 [1] => 2 [2] => 10 [3] => 3 [4] => 5 [5] => 6 [6] => 11 [7] => 9 [ 8] => 4 [9] => 8 )
如果我理解正确,您想使用 $arr1 的值作为 $arr2 中的键。
$values = array_values($arr1);
=> 这将为您提供 $arr1 的值。 你可以使用,
array_combine($keys, $values);
因此结果数组将是,
$result_arr = array_combine(array_values($arr1), array_values($arr2));
但是,如果两个数组中的项目数不同,则可能无法按预期工作。
