在 PHP 中创建关联数组

Question

如何编写 PHP 代码来手动创建这个数组？

Array ( 
[0] => Array 
    ( 
        [Id] => 2 
        [Fruit] => Apple 
    ) 
[1] => Array 
    ( 
        [Id] => 5 
        [Fruit] => Orange
    ) 
)

Answer 1

$arr = array();
$arr[] = array("Id" => 2, "Fruit" => "Apple");
$arr[] = array("Id" => 5, "Fruit" => "Orange");

Answer 2

$array =array(
                array('Id'=>2, 'Fruit'=>'Apple'),
                array('Id'=>5, 'Fruit'=>'Orange')                     
              );

注意：数组键区分大小写。

Answer 3

$array = array();
$array[] = array(
    'id'=>3,
    'Fruit'=>'Orange'
);
$array[] = array(
    'id'=>7,
    'Fruit'=>'Banana'
);
