如何在
PHP中使用json_encode()创建一个具有以下结构的数组：
Array(
[1] => Array(
[id] => 1
[data] => 45
)
[2] => Array(
[id] => 3
[data] => 54
)
);
尝试这样的事情：

$myArray = array();
//set up the nested associative arrays using literal array notation
$firstArray = array("id" => 1,"data" => 45);
$secondArray = array("id" => 3,"data" => 54);
//push items onto main array with bracket notation (this will result in numbered indexes)
$myArray[] = $firstArray;
$myArray[] = $secondArray;
//convert to json
$json = json_encode($myArray);
