PHP Multidimensional Array

##Arrays with more than one dimension can be called multidimensional arrays

We need to understand that an array is not necessarily a next-dimensional array A simple list of indexes and values. In fact, each element in the array can also be another array

So if the array element in a one-dimensional array is an array, then it becomes a two-dimensional 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 two- or three-dimensional arrays:

Example

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

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("
"); // 格式化输出数组 print_r($sites); print("
"); ?>

Example 2

Let us try to display a value in the above array:

echo $sites['php'][0] . 'The address is:' . $sites['php'][1];
