Array (
    0 => array ( "point1.0" => "some data","point2.0" => "some data" )
    1 => array ( "point1.1" => "some data","point2.1" => "some data" )
)

然后我将要插入的数组作为第一个元素

$newArray = array("point1.2" => "some data","point2.2" => "some data" )

我的结果应该是

Array (
    0 => array ( "point1.2" => "some data","point2.2" => "some data" )
    1 => array ( "point1.0" => "some data","point2.0" => "some data" )
    2 => array ( "point1.1" => "some data","point2.1" => "some data" )
)

在这种情况下,array_unshift似乎失败了.有没有比创建新数组和通过foreach循环插入每个子数组更好的解决方案？
