我正在尝试为$ matchno设置正确的值。 它应该仅增加1。下面是输出数组的代码和示例，我手动更改了数组，以显示我希望数组如何。关注的只有$ matchno
$max = 16;
$tournament_size = $max / 2;
$rounds = log($tournament_size) / log(2);
$curr = $tournament_size / 2;
$offset = $max;
$matchnoInBlock = -1;
for ($i = 0; $i < $rounds; $i++)
{
$inner = array();
for ($i2 = 0; $i2 < $curr; $i2++)
{
$matchnoInBlock++;
$matchno = $matchnoInBlock + $offset;
$inner[] = array(0, 0, $matchno);
}
$lower_bracket_results[] = $inner;
$lower_bracket_results[] = $inner;
$curr /= 2;
}
echo '<pre>';
print_r($lower_bracket_results);
echo '</pre>';
阵列输出： -

我希望数组是这样的:(唯一不同的是$ matchno）
Array

[1] => 0
[2] => 16
)

对此有任何帮助，谢谢
答案 0 :(得分：1)
如果我的问题正确无误，您只需在将其分配给数组后再增加$matchno。
$matchno = 16;
for($x = 0; $x <= 3; $x++)
{
$lower_bracket_results[0][$x][2] = $matchno;
$matchno++;
}
或以较短的方式
$matchno = 16;
for($x = 0; $x <= 3; $x++)
{
$lower_bracket_results[0][$x][2] = $matchno++;
}
因为在你的代码中你有一个双重
$lower_bracket_results[] = $inner;
$lower_bracket_results[] = $inner;
我假设您需要构建此阵列的2倍但仍然会增加$matchno。您的问题是您将相同的$inner数组分配给数组$lower_bracket_results中的2个条目。您可以在函数中包装用于创建内部数组的逻辑，并将其调用2次。 $matchnoInBlock是passed by reference，因此在函数内部可以增加主上下文传递的相同变量的值。
这里看起来如何，而不会改变你编写它的方式：
<?php
function createInnerArray($curr, $offset, &$matchnoInBlock) {
$inner = array();
for ($i2 = 0; $i2 < $curr; $i2++)
{
$matchnoInBlock++;
$matchno = $matchnoInBlock + $offset;
$inner[] = array(0, 0, $matchno);
}
return $inner;
}
$max = 16;
$tournament_size = $max / 2;
$rounds = log($tournament_size) / log(2);
$curr = $tournament_size / 2;
$offset = 16;
$matchnoInBlock = -1;
for ($i = 0; $i < $rounds; $i++)
{
$lower_bracket_results[] = createInnerArray($curr, $offset, $matchnoInBlock);;
$lower_bracket_results[] = createInnerArray($curr, $offset, $matchnoInBlock);;
$curr /= 2;
}
echo '<pre>';
print_r($lower_bracket_results);
echo '</pre>';
