如何在Laravel或PHP中检查不重复和不连续的数字？

<?php
// 待检查的数字序列
$numbers = [1, 3, 5, 2, 4, 7, 9, 8];

// 移除重复元素
$uniqueNumbers = array_unique($numbers);

// 对数组进行排序
sort($uniqueNumbers);

// 检查连续性和不连续性
$missingNumbers = [];
$discontinuousNumbers = [];

for ($i = 0; $i < count($uniqueNumbers) - 1; $i++) {
    // 检查连续性
    if ($uniqueNumbers[$i] + 1 != $uniqueNumbers[$i + 1]) {
        $missingNumbers[] = $uniqueNumbers[$i] + 1;
    }
    
    // 检查不连续性
    if ($uniqueNumbers[$i] + 1 != $uniqueNumbers[$i + 1]) {
        $discontinuousNumbers[] = $uniqueNumbers[$i] + 1;
    }
}

// 输出结果
echo "不重复的数字序列：";
foreach ($uniqueNumbers as $number) {
    echo $number . " ";
}

echo "<br>缺失的数字：";
foreach ($missingNumbers as $missingNumber) {
    echo $missingNumber . " ";
}

echo "<br>不连续的数字：";
foreach ($discontinuousNumbers as $discontinuousNumber) {
    echo $discontinuousNumber . " ";
}
?>
