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