(PHP)初始化空的多维数组，然后填充它

Question

我想创建一个包含3种类型信息的数组：name、id和work。首先，我只想初始化它，这样以后就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，这就是我想到的：

$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数组时得到的结果：

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

我做错了什么？

Answer 1

非常简短的回答：

$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 2

您可以简单地创建它，如下所示：

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

然后稍后添加到只说：

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

Answer 3

尝试以下代码：

$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;
