（PHP）初始化空的多维数组，然后填充它

Question

我想用3种类型的信息创建一个数组：名称，ID和工作。首先，我想对其进行初始化，以便以后可以用变量中包含的数据填充它。

我搜索了如何初始化多维数组，以及如何填充它，这就是我想出的：

$other_matches_info_array = array(array());

$other_matches_name = "carmen";
$other_matches_id = 3;
$other_matches_work = "SON";

array_push($other_matches_info_array['name'], $other_matches_name);
array_push($other_matches_info_array['id'], $other_matches_id);
array_push($other_matches_info_array['work'], $other_matches_work);

这是我print_r数组得到的结果：

Array
(
  [0] => Array
    (
    )
  [name] =>
)

我做错了什么？

Answer 1

您可以像这样简单地创建它：

$arrayMultiDim = [ 
    [
      'id' => 3,
      'name' => 'Carmen'
    ],
    [
      'id' => 4,
      'name' => 'Roberto'
    ]
];

然后再加上只是说：

$arrayMultiDim[] = ['id' => 5, 'name' => 'Juan'];

Answer 2

非常简短的答案：

$other_matches_info_array = array();
// or $other_matches_info_array = []; - it's "common" to init arrays like this in php

$other_matches_name = "carmen";
$other_matches_id = 3;
$other_matches_work = "SON";

$other_matches_info_array[] = [ 
    'id' => $other_matches_id,
    'name' => $other_matches_name
];
// so, this means: new element of $other_matches_info_array = new array that is declared like this.

Answer 3

尝试下面的代码：

$other_matches_info_array_main = [];

$other_matches_name = "carmen";
$other_matches_id = 3;
$other_matches_work = "SON";

$other_matches_info_array['name'] = $other_matches_name;
$other_matches_info_array['id'] = $other_matches_id;
$other_matches_info_array['work'] = $other_matches_work;


$other_matches_info_array_main[] = $other_matches_info_array;
