php - 我想使用循环将元素添加到随机位置的数组中

我想使用循环在任意位置向数组中添加一个元素
我有一个固定的队伍如下

$ranks=array("10","9","8","7","6","5","4","3","2","1");

我有一个根据链子随机排列的位置，

$agent_ranks=array("10","6","2","1");

缺少索引
我已经计算出了数组之间的差异

$arr_diff=array("9","8","7","5","4","3");

现在我想要一个动态数组作为结果：

$arr_diff_new=array("0","9","8","7","0","5","4","3","0","0");

如何在缺少的索引处添加value="0"？

最佳答案

您可以使用in_array和for循环执行此操作：

$ranks=array("10","9","8","7","6","5","4","3","2","1");
$agent_ranks=array("10","6","2","1");

for($i=0;$i < count($ranks); $i++){
    if(in_array($ranks[$i], $agent_ranks)){
        $newarray[$i] = 0;
    }else{
        $newarray[$i] = $ranks[$i];
    }
}
print_r($newarray);
