我想从数组中提取数据(具有键和值的原始数组).在我提取数组之后,我想要两个新数组,第一个只有键,第二个只有值,两个都没有索引(参见代码示例).

// original array 
$array = array(
    "name1"=>500
   ,"name2"=>400
   ,"name3"=>300
   ,"name4"=>200
   ,"name5"=>100
);

// after extraction
$array1 = array('name1','name2','name3','name4','name5');
$array2 = array(500,400,300,200,100);

// not like this
// $array1 = array(0=>'name1',1=>'name2',2=>'name3',3=>'name4',4=>'name5);
// $array2 = array(0=>500,1=>400,2=?300,3=>200,4=>100);

解决方法:

$array1 = array_keys($array);
$array2 = array_values($array);

好吧,你可以阅读here.

In computer science, an array data structure or simply an array is a
data structure consisting of a collection of elements (values or
variables), each identified by at least one array index or key. An
array is stored so that the position of each element can be computed
from its index tuple by a mathematical formula.
