我这里有一些函数，正在努力获得正确的输出。
主要思想是使用称为buildinginfo的函数并调用函数avaliableBuildingBuildings来循环buildinginfo的数组和循环槽需求，以确定需求是否完整。
在我的数据库中，我的main_building级别是 1。
每隔一个表，都是空的。
调用avaliableBuildingBuildings时，我在此行下获得输出，这将列出我可以创建的建筑物。 你可以看到main_building的要求是3，那么不应该创建军营。
问：如何修复我的代码，以便它能准确地为我提供可以建造的建筑物数组？
电流输出：
array(5) {
["barracks"]=>
array(2) {
["max"]=>
int(1)
["requirements"]=>
array(2) {
["main_building"]=>
int(3)
["rally_point"]=>
int(1)
}
}
["blacksmith"]=>
array(2) {
["max"]=>
int(1)
["requirements"]=>
array(3) {
["main_building"]=>
int(3)
["academy"]=>
int(3)
["barracks"]=>
int(3)
}
}
["embassy"]=>
array(2) {
["max"]=>
int(1)
["requirements"]=>
array(1) {
["main_building"]=>
int(1)
}
}
["marketplace"]=>
array(2) {
["max"]=>
int(1)
["requirements"]=>
array(3) {
["warehouse"]=>
int(1)
["granary"]=>
int(1)
["main_building"]=>
int(3)
}
}
["palace"]=>
array(2) {
["max"]=>
int(1)
["requirements"]=>
array(3) {
["main_building"]=>
int(5)
["embassy"]=>
int(1)
["residence"]=>
int(0)
}
}
}

看起来您的需求检查循环增加了一倍。这导致检查是否可以建造任何所需的建筑物（并且由于没有嵌套要求，因此始终可以）。只要摆脱内部循环，它应该没问题。
function avaliableBuildingBuildings($villageid) {
$avaliable = $this->avaliableBuildings($villageid);
$tobuild = array();
foreach ($avaliable as $name => $built) {
if (isset($built['requirements'])) {
if ($this->requirementsDone($villageid, $name)) {
echo "verify to build $name is true <br><br>";
$tobuild[$name] = $avaliable[$name];
} else {
echo "verify to build $name is false <br><br>";
}
} else {
}
}
return $tobuild;
}
附言。这些"回声"无济于事，是吗:)想想TDD - 这个过程解决的问题不仅仅是逻辑错误（它会迫使你引入假数据层，例如 ->解耦代码）
