php如何传递数组给函数处理并返回

之前的代码如下,每次只能传递一个参数进来处理返回
public function cleanSpace($trimStr){
if($trimStr != ""){
$trimStr = trim($trimStr);
}
return $trimStr;
}
遇到多个数据的处理显得很繁琐，请问如何将数组传递进来，【无论有多少个键】都可以灵活处理，并将数组返回呢？
如下面这个数组

$userInfo = array(
'userName'=>$userName,
'passWord'=>$passWord,
'nickName'=>$nickName,
'lv'=>$lv,
'tel'=>$tel,
'state'=>$state,
'email'=>$email,
'teamParentID'=>$teamParentID
);

Answer 1

public function cleanSpace($trimArr){
foreach($trimArr as $key=>$val){
if($val != ""){
$trimArr[$key] = trim($val);
}
}
return $trimArr;
}

Answer 2

一样的传法
public function cleanSpace($trimArr){
foreach($trimArr as $key=>$val){
if($val != ""){
$trimArr[$key] = trim($val);
}
}
return $trimArr;
}
