我正在尝试将数组作为第一个元素插入到多维数组中。原始数组的示例
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
$newArray = array("point1.2" => "some data", "point2.2" => "some data" )
我的结果应该是
Array (
0 => array ( "point1.2" => "some data", "point2.2" => "some data" )
1 => array ( "point1.0" => "some data", "point2.0" => "some data" )
2 => array ( "point1.1" => "some data", "point2.1" => "some data" )
)
在这种情况下,array_unshift似乎失败了。有没有比创建新数组和通过foreach循环插入每个子数组更好的解决方案?
答案 0 :(得分:14)
array_unshift
应该适合你。应该注意的是,函数修改传递给它的数组并且不返回新数组,因此你应该不将返回值赋给数组变量。
正确:
array_unshift($arr, $newArray);
不正确:
$arr = array_unshift($arr, $newArray);
