在PHP中创建关联数组

Question

如何编写PHP代码以手动创建此数组？

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')      
      ); 

NB：数组键是大小写敏感的。

Answer 3

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