for循环如何分组括号？

Question

我有一个关于在 for 循环中将括号组合在一起的问题。我使用 for 循环将锦标赛结果存储在数组中，但想按轮次对结果进行分组。我想对每一轮进行分组。看看下面的代码，您可以比较我想如何更改代码以匹配所需的输出：

$tournament_size = 16;

$upper_bracket_total_matches = $tournament_size - 1;
$lower_bracket_total_matches = $tournament_size - 2;

for($i = 1; $i <= $upper_bracket_total_matches; $i++)
{
    $upper_brackets[]= "[0,0]";
}

$upper_bracket_results = implode(",", $upper_brackets)

/* Upper Bracket Output 
[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],
[0,0],[0,0],[0,0],[0,0],
[0,0],[0,0],
[0,0]
*/

/* Desired Upper Bracket Output 
[[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0]],
[[0,0],[0,0],[0,0],[0,0]],
[[0,0],[0,0]],
[[0,0]]
*/

for($i = 1; $i <= $lower_bracket_total_matches; $i++)
{
    $lower_brackets[]= "[0,0]";
}

$lower_bracket_results = implode(",", $lower_brackets);

/* Lower Bracket Output
[0,0],[0,0],[0,0],[0,0],
[0,0],[0,0],[0,0],[0,0],
[0,0],[0,0],
[0,0],[0,0],
[0,0],
[0,0]
*/

/* Desired Lower bracket Output
[[0,0],[0,0],[0,0],[0,0]],
[[0,0],[0,0],[0,0],[0,0]],
[[0,0],[0,0]],
[[0,0],[0,0]],
[[0,0]],
[[0,0]]
*/

希望这是清楚的感谢您的帮助

Answer 1

试试这个：它根据大小生成东西：

<?php

$tournament_size = 8;
$rounds = log($tournament_size) / log(2);

$upper_bracket_results = array();
$lower_bracket_results = array();

$curr = $tournament_size;

for ($i = 0; $i <= $rounds; $i++) {
    $inner = array();

    for ($i2 = 0; $i2 < $curr; $i2++)
        $inner[] = array(0, 0);

    $curr /= 2;
    $upper_bracket_results[] = $inner;
}

$curr = $tournament_size / 2;

for ($i = 0; $i < $rounds; $i++) {
    $inner = array();

    for ($i2 = 0; $i2 < $curr; $i2++)
        $inner[] = array(0, 0);

     $lower_bracket_results[] = $inner;
     $lower_bracket_results[] = $inner;

    $curr /= 2;
}

echo "Upper:\n\n";
echo json_encode($upper_bracket_results);
echo "\n\nLower:\n\n";
echo json_encode($lower_bracket_results);

Output:

Upper:

[[[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0],[0,0]],[[0,0],[0,0],[0,0],[0,0]],[[0,0],[0,0]],[[0,0]]]

Lower:

[[[0,0],[0,0],[0,0],[0,0]],[[0,0],[0,0],[0,0],[0,0]],[[0,0],[0,0]],[[0,0],[0,0]],[[0,0]],[[0,0]]]
