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 two- or three-dimensional arrays:
Example
<?php
// 二维数组:
$cars = array
(
array("Volvo",100,96),
array("BMW",60,59),
array("Toyota",110,100)
);
?>
Run Example»
PHP - Multidimensional Array
A multidimensional array is an array that contains 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 multi-dimensional array with automatically assigned ID keys:
Example
<?php
$sites = array
(
"php"=>array
(
"php中文网",
"http://www.php.cn"
),
"google"=>array
(
"Google 搜索",
"http://www.google.com"
),
"taobao"=>array
(
"淘宝",
"http://www.taobao.com"
)
);
print("<pre>"); // 格式化输出数组
print_r($sites);
print("</pre>");
?>The above array will be output as follows ：
Array
(
[php] => http://www.php.cn
)
‐ ‐ [1] ‐ ‐ ‐ ‐ ‐ [1] => http://www.google.com
)
## [TaoBao] = & GT; Array
(
[0] = & GT; Taobao
[1] = & gtp; http ://www.taobao.com
)
)
##Example 2
Let’s Try to display a value in the above array:
echo $sites['php'][0] . 'The address is:' . $sites['php'][1];
The above code will output:
PHP Chinese website address is: http://www.php.cn
Example 3<?php
$all = array("fruits" => array("a"=>"orange","b"=>"banana","c"=>"apple"),
"ages" => array(18, 20, 25)
);
echo $all["fruits"]["c"]; //输出apple
echo $all["ages"][0]; //输出18
?>
