PHP Array Multidimensional
Description
A multi-dimensional array can have array as its value.
An array that contains other arrays is a two-dimensional array. If those arrays also contain arrays, then the top-level array is a three-dimensional array, and so on.
Example
The following code uses array operator ([]) to create an two-dimensional array. The key of the first level is Java and PHP.
<?PHP//from ww w.j ava 2 s .c o m
$book['Java'] = array("Name"=>"Java Book", "Price"=> 1.2, "OnSale"=>"No");
$book['PHP'] = array("Name"=>"PHP Book", "Price"=>5.3, "OnSale"=>"Yes");
var_dump($book);
?>
The code above generates the following result.
Example 2
The following script creates a simple two-dimensional array called $myBooks , then displays its contents using print_r().
<?php //from w w w.j a va 2s.co m
$myBooks = array(
array(
"title" => "Learn PHP from java2s.com",
"author" => "java2s.com",
"pubYear" => 2000
),
array(
"title" => "Learn Java from java2s.com",
"author" => "JavaAuthor",
"pubYear" => 2001
),
array(
"title" => "Learn HTML from java2s.com",
"author" => "HTMLAuthor",
"pubYear" => 2002
),
array(
"title" => "Learn CSS from java2s.com",
"author" => "CSSAuthor",
"pubYear" => 2003
),
);
print_r ( $myBooks );
?>
The code above generates the following result.
