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");//設(shè)置編碼 
$sites = array ( 
        "php"=>array ( 
            "php中文網(wǎng)", 
            "http://miracleart.cn" 
        ), 

        "google"=>array ( 
            "Google 搜索", 
            "http://www.google.com" 
        ), 

        "taobao"=>array( 
            "淘寶", 
            "http://www.taobao.com" 
        ) 
); 
print("<pre>"); // 格式化輸出數(shù)組 
print_r($sites); 
print("</pre>"); 
?>
