PHP如何根据多个条件过滤数组

Question

我有以下数组，我想根据某些条件更改输出

   foreach($courses as $c) {
$c->type == "fulltime" ? 'full' : 'part';
                    $f = new stdClass();
                    $f->course_id = $c->course;
                    $f->form =  $c->id;
                    $f->module = $c->module;
                    $f->unread = $unreadcount;
                    $f->type = $c->type;
                    $f->posts = $posts;   
                
                 $results[$c->course_id][$c->type][] = $f;
    }

当前结构：

 [course_id]{
       full : [
                       $f->form =  $c->id;
                    $f->module = $c->module;
                    $f->type = $c->type; [ex: fulltime, parttime]
                  
            ]
    part : []
    posts : []
    }

条件：

if ($enableFulltimeCourse =1 && $unreadcount >0) -> 显示 full[] 和 part[] 否则为空 if ($enableParttimeCourse =1 && $f->type == "part") -> 显示部分[] 否则为空

我尝试了什么

if ($enableFulltimeCourse =1 && $unreadcount >0){
                    unset($f);
                }
                $results[$forum->course][$forum->type][] = $f;

请指教

您需要使用== 或=== 进行比较。另外，不确定你的意思是 show X else it's empty，但这里是如何形成你的条件。我不认为您的意思是 unset($f); - 因为那会删除您的整个对象。

if ($enableFulltimeCourse == 1)
  if ($unreadcount >0){
    // show full[] and part[] else its empty
    foreach($f->full as $item) {
       // loop through the full
    }

    foreach($f->part as $item) {
       // loop through the part
    }
  } else if ($f->type == "part") {
    unset($f->full); //show part[] else its empty
    foreach($f->part as $item) {
       // loop through the part
    }
  }
}
$results[$forum->course][$forum->type][] = $f;
