php Multidimensional array
The value in one array can be another array, and the value of another array can also be an array. In this way, we can create a two-dimensional or three-dimensional array:
Create a two-dimensional array
Format:
array(
array(1,2,3,4,5),
array(6,7,8,9,10)
)
Example 1:
<?php $arr = array( array(1,2,3,4,5), array(6,7,8,9,10) ); echo "<pre>"; print_r($arr); echo "</pre>"; ?>
Example 2: Create a multidimensional array
<?php header("Content-type: text/html; charset=utf-8");//设置编码 $sites = array ( "php"=>array ( "php中文网", "http://www.php.cn" ), "google"=>array ( "Google 搜索", "http://www.google.com" ), "taobao"=>array( "淘宝", "http://www.taobao.com" ) ); print("<pre>"); // 格式化输出数组 print_r($sites); print("</pre>"); ?>
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
