Question

我怎么能够像现在这样在PHP建造一个阵列?

它应当具有独特的钥匙,其相应的价值是阵列,这些阵列对每个钥匙都有多个要素。

Array (
    42 => Array ( 56, 86, 97 )
    51 => Array ( 64, 52 )
)

Answer 1

$main = array();
for ($i=0; $i<10; $i++) {
  // $i makes numeric keys
  $main[$i] = array();

  // Or instead, you could make a truly unique key name for each:
  $main[uniqid()] = array(...somevalues...);

}

创造这样的东西:

Array
(
    [4f105f361cdd1] => Array
        (
        )

    [4f105f361cf24] => Array
        (
        )

    [4f105f361cf33] => Array
        (
        )

    [4f105f361cf3c] => Array
        (
        )

    [4f105f361cf44] => Array
        (
        )

)

Answer 2

$arr = array(
    42 => array(56, 86, 97),
    51 => array(64, 52)
);

var_dump($arr);

Answer 3

$arraytest = array(
           42 => array(56, 86, 97), 
           51 => array(64, 52)
           );

var_dump($arraytest);

Answer 4

$array = array(
  42 => array(56,86,97),
  51 => array(64,52)
);
