将数组索引转换为自定义值？

Question

我有一个数组$ indexedarray

printr（$ indexedarray）给出了类似的东西

array (size=3)
  0 => string 'Homes' (length=5)
  1 => string 'Apartments' (length=10)
  2 => string 'Villas' (length=6)

我想更改此数组索引也与值相同，如

array (size=3)
  'Homes' => string 'Homes' (length=5)
  'Apartments' => string 'Apartments' (length=10)
  'Villas' => string 'Villas' (length=6)

是不可能的？

Answer 1

您可以使用array_combine：

$indexedarray= ['Homes', 'Apartments', 'Villas'];
print_r(array_combine($indexedarray, $indexedarray));

<强>给出：

Array
(
    [Homes] => Homes
    [Apartments] => Apartments
    [Villas] => Villas
)

但请注意，您的重复值将被删除。钥匙将是独一无二的！

Answer 2

试试这个：

$myArray = [
   0 => 'Homes',
   1 => 'Apartments',
   2 => 'Villas' ];


$newArray = [];

foreach($myArray as $key => $value){
  $newArray[$value] = $value;
}

var_dump($newArray);
