如何将关联数组排序为可选最大最小顺序？

Question

有谁知道如何将关联数组排序为交替最大最小值？

I.E.

array("A"=>10, "B"=>2, "C"=>5, "D"=>1, "E"=>30, "F"=>1, "G"=>7) 

应该改为：

array("E"=>30, "D"=>1, "A"=>10, "F"=>1, "G"=>7, "B"=>2, "C"=>5) 

感谢

Answer 1

基础上回答到以前的版本这个问题：

$myArray = array("A"=>10, "B"=>2, "C"=>5, "D"=>1, "E"=>30, "F"=>1, "G"=>7); 
asort($myArray); 
$myArrayKeys = array_keys($myArray); 

$newArray = array(); 
while (!empty($myArray)) { 
    $newArray[array_shift($myArrayKeys)] = array_shift($myArray); 
    if (!empty($myArray)) 
     $newArray[array_pop($myArrayKeys)] = array_pop($myArray); 
} 
var_dump($newArray); 

，或者，如果你想最大的第一：

$myArray = array("A"=>10, "B"=>2, "C"=>5, "D"=>1, "E"=>30, "F"=>1, "G"=>7); 
asort($myArray); 
$myArrayKeys = array_keys($myArray); 

$newArray = array(); 
while (!empty($myArray)) { 
    $newArray[array_pop($myArrayKeys)] = array_pop($myArray); 
    if (!empty($myArray)) 
     $newArray[array_shift($myArrayKeys)] = array_shift($myArray); 
} 
var_dump($newArray);
