我在PHP中有一个数组:
Array (
[0] => Red
[1] => Green
[2] => Blue
[3] => Yellow
[4] => Purple
[5] => Orange
[6] => Brown )
我希望这个数组被洗牌,除了前三个元素([0] [1] [2]应该保持在同一个位置)。 E.g:
Array (
[0] => Red
[1] => Green
[2] => Blue
[3] => Brown
[4] => Yellow
[5] => Purple
[6] => Orange )
我知道如何使用shuffle( $array );
对整个数组进行随机播放,但我需要建议如何不对该数组的前三个元素进行随机播放。谢谢!

你可以这样做:
$a=array("red","green","blue","yellow","brown");
$partA = array_slice($a,0,3);
$partB = array_slice($a,3,sizeof($a));
shuffle($partB);
$result = array_merge($partA, $partB);
print_r($result);
