PHP 循环检查一组数字是否连续

Question

我试图遍历一组记录，所有记录都有一个“数字”属性。我正在尝试检查是否有 3 个连续的记录，例如 6、7 和 8。

我想我几乎已经完成了下面的代码，虽然在最后阶段遇到了困难 - 任何帮助都会很棒!

$nums = array();
while (count($nums <= 3))
{
    //run through entries (already in descending order by 'number'
    foreach ($entries as $e)
    {
        //ignore if the number is already in the array, as duplicate numbers may exist
        if (in_array($e->number, $num))
            continue;
        else
        {
            //store this number in the array
            $num[] = $e->number;
        }
    //here i need to somehow check that the numbers stored are consecutive
    }
}

Answer 1

function isConsecutive($array) {
    return ((int)max($array)-(int)min($array) == (count($array)-1));
}

您也可以在不循环的情况下获得相同的结果。
