$id = 14
public function selectRosterList($id)
{
$data = db("department")->where("pid",$id)->select();
$rosters = [];
foreach ($data as $key=>$value){
$roster = db("roster")->where("did",$value["id"])->select();
$rosters = array_merge($rosters, $roster);
if ($value["pid"] != 0){
$this->selectRosterList($value["id"]);
}
}
return $rosters;
}
Why can I only get the data of Zhang San and Li Si but not Xiaoming when I write like this?
