PHP multidimensional array
The values in one array can be another array, and the values in another array can also be an array. In this way, we can create a two-dimensional or three-dimensional array:
Instance
<?php
// 二维数组:
$cars = array
(
array("Volvo",100,96),
array("BMW",60,59),
array("Toyota",110,100)
);
print_r($cars);

PHP - Multidimensional Array
A multidimensional array is an array containing one or more arrays.
In a multi-dimensional array, each element in the main array can also be an array, and each element in the sub-array can also be an array.
Example
In this example, we create a multidimensional array with automatically assigned ID keys:
Example
<?php
$sites = array
(
"php"=>array
(
"php中文网",
"//m.sbmmt.com"
),
"google"=>array
(
"Google 搜索",
"http://www.google.com"
),
"taobao"=>array
(
"淘宝",
"http://www.taobao.com"
)
);
print("<pre>"); // 格式化输出数组
print_r($sites);
print("</pre>");
?>Run Instance»
Click the "Run Instance" button to view the online instance
The above array will be output as follows:
Example 2
Let us try to display a certain value in the above array:
echo $sites['php'][0] . '地址为：' . $sites['php'][1];The above code will output:
