json_encode() で次の構造になる配列を PHP で作成する方法:

Array(
[1] => Array(
    [id] => 1
    [data] => 45
)
[2] => Array(
    [id] => 3
    [data] => 54

より短い方法は次のとおりです。

$myArray = array();

$myArray[] = array("id" => 1, "data" => 45);
$myArray[] = array("id" => 3, "data" => 54);

//convert to json
$json = json_encode($myArray);
