PHP 将数组递增 1

Question

我有一个简单的数组，我正在尝试构建一个函数以将其递增到例如最大值，并且我无法对2个键重用相同的数字。但到目前为止，我几乎没有取得什么成功。这就是我现在所拥有的。$iteration=[0,1,2,3,4]$max=12

//$iteration is my array and $max is the maximum value a key can have.

IncrementIteration($iteration,$max){

    $count=count($iteration);

    while($count > 0){

        if( ($iteration[($count-1)] < $max) ){

            $iteration[($count-1)]++;

            break;

        }

        $count--;

    }

    return $iteration;

}

但这绝不会重置递增的键后面的键，并且不会考虑该数字是否已使用。

以下是我正在寻找的结果示例：

print_r(IncrementIteration([0,1,2],12))

输出：数组 （ [0] => 0 [1] => 1 [2] => 3 ）

print_r(IncrementIteration([0,1,12],12))

输出：数组 （ [0] => 1 [1] => 2 [2] => 3 ）

print_r(IncrementIteration([0,11,12],12))

输出：数组 （ [0] => 1 [1] => 2 [2] => 3 ）

这将是可能的最高增量。

print_r(IncrementIteration([10,11,12],12))

输出：数组 （ [0] => 10 [1] => 11 [2] => 12 ）

感谢您对此代码的任何帮助。

也许像这样的事情可以有所帮助，&nbsp; function unique_keys_array($array) {&nbsp; &nbsp; $temp_array = array();&nbsp; &nbsp; $i = 0;&nbsp; &nbsp; $key_array = array();&nbsp; &nbsp; foreach($array as $key) {&nbsp; &nbsp; &nbsp; &nbsp; if (!in_array($key, $key_array)) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $key_array[$i] = $key;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $temp_array[$i] = $key;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; $i++;&nbsp; &nbsp; }&nbsp; &nbsp; return $temp_array;}print_r(unique_keys_array([1,2,2,3,4,5,6,7,8,8,9,9]));returns Array(&nbsp; &nbsp; [0] => 1&nbsp; &nbsp; [1] => 2&nbsp; &nbsp; [3] => 3&nbsp; &nbsp; [4] => 4&nbsp; &nbsp; [5] => 5&nbsp; &nbsp; [6] => 6&nbsp; &nbsp; [7] => 7&nbsp; &nbsp; [8] => 8&nbsp; &nbsp; [10] => 9)

Here is my final code for my Reverse Sumfunction ReverseSUM($value,$array){&nbsp; &nbsp; ini_set('max_execution_time', 10);&nbsp; &nbsp; if (!function_exists('GenerateIteration')) {&nbsp; &nbsp; &nbsp; &nbsp; function GenerateIteration($number){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; global $debug;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $iteration=array();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

And the $invoice array contains all the invoice lines totals.Code available on GitHub : https://github.com/LouisOuellet/ReverseSUMSheers
