php构造关联数组键值增量循环

下面是我正在努力实现的目标

Array
(
    [0.94] => 35
    [0.93] => 36
    [0.92] => 37
    [0.91] => 38
    .
    .
    .
    [0.50] => 79
)

而不是建筑

$arrayName1 = array('0.94' => '35',
                    '0.93' => '36',
                    '0.92' => '37',
                    '0.91' => '38',
                    '0.50' => '79'
                  );

我想知道是否有一种方法可以添加循环来简化流程。任何人？

具有

range（）

和

array\u combine（）

功能：

$result = array_combine(range(0.94, 0.5, -0.01), range(35, 79));

$result

包含：

Array
(
    [0.94] => 35
    [0.93] => 36
    [0.92] => 37
    [0.91] => 38
    [0.9] => 39
    [0.89] => 40
    [0.88] => 41
    [0.87] => 42
    [0.86] => 43
    [0.85] => 44
    [0.84] => 45
    [0.83] => 46
    [0.82] => 47
    [0.81] => 48
    [0.8] => 49
    [0.79] => 50
    [0.78] => 51
    [0.77] => 52
    [0.76] => 53
    [0.75] => 54
    [0.74] => 55
    [0.73] => 56
    [0.72] => 57
    [0.71] => 58
    [0.7] => 59
    [0.69] => 60
    [0.68] => 61
    [0.67] => 62
    [0.66] => 63
    [0.65] => 64
    [0.64] => 65
    [0.63] => 66
    [0.62] => 67
    [0.61] => 68
    [0.6] => 69
    [0.59] => 70
    [0.58] => 71
    [0.57] => 72
    [0.56] => 73
    [0.55] => 74
    [0.54] => 75
    [0.53] => 76
    [0.52] => 77
    [0.51] => 78
    [0.5] => 79
)

你可以简单地循环

$data = array();
$i = 0.94;
$j = 35;
while($i > 0.50){
    $data[(string)$i] = $j;
    $i -= 0.01;
    $j++;
}

var_dump($data);

“我想知道是否有办法添加循环”是的，确实有。您尝试过什么？数组键必须是整数或字符串（不是浮点）。。。。如果要使用（模拟的）浮点键，则使用生成器op的数字处于禁用状态。这些数字给出了不同长度的数组和一个错误。键数组长一个元素。可能在

.5

结束，或者在

80

结束@abracadver，我不明白你说的数字是什么意思off@AbraCadaver，这真是令人讨厌的PHP行为是的，似乎PHP7只转到了

.5

，即使您使用了

0.49

@AbraCadaver，它似乎一直工作到PHP

7.0.2

，对于所有进一步/更新的版本-抛出警告
