php 动态调用方法

$searchActionArr = [
　　'1' => 'searchAlbumList',
　　'2' => 'searchUser',
　　'3' => 'searchActivityList',
];
if(filled($searchActionArr[$searchType]) && method_exists($this,$searchActionArr[$searchType])){
　　$instanceMethod = $searchActionArr[$searchType];
　　$result = $this->$instanceMethod($searchName);
　　result = $this->{$searchActionArr[$searchType]}($searchName);
}

或 使用“{}”，参考在php中{}的作用 

if(filled($searchActionArr[$searchType]) && method_exists($this,$searchActionArr[$searchType])){
　　result = $this->{$searchActionArr[$searchType]}($searchName);
}
