我创建了一个数组，该数组需要显示当前用户的项目列表。每个项目都是由阶段组成的，每个阶段可以分配有多个KPI。
如您所见，这些阶段都很好地附加到了数组上，并且大多数情况下，KPI也是如此。
并非特定于阶段的KPI例外。当我拥有这种类型的KPI时，应将其分配到项目部分，因为它跨多个阶段。
KPI由PSID分配给各个阶段，如果id为null，则它是项目范围的KPI。
我遇到的问题是项目范围的KPI。它们是重复的，我需要每个KPI在数组中出现一次。
我试图用当前推送的元素检查先前推送的数组元素，以便进行检查。
$i=0;
foreach($projects as $project){
$projectStages = $this->ProjectStages->find('all',
array(
'conditions' => array(
'pid' => $project['Projects']['pid']
)
)
);
array_push($projects[$i], $projectStages);
$n=0;
foreach($projectStages as $stage){
$projectKPIs = $this->ProjectKPIs->find('all',
array(
'conditions' => array(
'nPid' => $project['Projects']['pid']
)
)
);
foreach($projectKPIs as $projectKPI){
if(empty($projectKPI['ProjectKPIs']['nPsid'])){
$N = $n-1;
$curpkid = $projectKPI['ProjectKPIs']['pkid'];
if(isset($projects[$i]['Projects'][$N]['ProjectKPIs']['pkid'])){
$prevpkid = $projects[$i]['Projects'][$N]['ProjectKPIs']['pkid'];
}else{
$prevpkid = null;
}
if($curpkid != $prevpkid){
echo 'cur: '.$curpkid.' - prev: '.$prevpkid;
array_push($projects[$i]['Projects'], $projectKPI);
}
}else if($projectKPI['ProjectKPIs']['nPsid'] == $stage['ProjectStages']['psid']){
array_push($projects[$i][$i][$n]['ProjectStages'], $projectKPI);
}
}
$n++;
}
$i++;
}

似乎您正在多次检索相同的确切数据库结果。我正在查看此代码块中的查找结果：
foreach($projectStages as $stage){
$projectKPIs = $this->ProjectKPIs->find('all',
array(
'conditions' => array(
'nPid' => $project['Projects']['pid']
)
)
);
// ...
}
在我看来，您将$projectKPIs在foreach的每次迭代中获得相同的结果集，$projectStages因为find forProjectKPIs正在使用项目ID，而与当前$stage值无关。
如此有效地在每个阶段中，您都可以再次遍历所有相同的KPI，从而使逻辑陷入混乱，从而避免重复。
也许可以通过重组foreach循环来简化此过程。我将放弃外部foreach($projectStages as $stage)，然后仅对所有KPI进行一次迭代。然后，仅当您需要针对进行测试时，才在该循环内迭代每个阶段$stage['ProjectStages']['psid']，这在当时可能实际上是不必要的。
