如果数组不够长，则重复数组值

Question

假设我有一个这样的数组:

$numbers = array("one", "two", "three", "four", "five");

什么是最好的方法，重复值在php中，如果数组有少于5个元素?例如，If array为:

$numbers = array("one", "two", "three")

我想得到这样的结果:

$numbers = array("one", "two", "three","one", "two").

如果数组有2个元素，我想要这样的结果:

$numbers = array("one", "two", "one", "two", "one").

如果数组只有一个元素，我想要这样的结果:

$numbers = array("one", "one", "one", "one", "one").

Answer 1

试试这个:

$numbers = array("one", "two");
$count = count($numbers);
for($i=$count; $i<=4;$i++){
    $numbers[] = $numbers[$i % $count];
}

Answer 2

如果你想让数组有随机的附加值，你可以这样做:-

$numbers = array("one", "two", "three");
while(count($numbers) < 5)
{
    $numbers[] = $numbers[mt_rand(0,count($numbers))];
}
var_dump($numbers);
