Answer 1

还可以是字典，

$new=$this->index_com();
//输出指定的值
echo$new[list];
}
publicfunctionindex_com(){
$list='a';
$category='b';
$totalCount='c';
$current='d';
returnarray('list'=>$list,'category'=>$category);
}
                            

Answer 2

publicfunctionindex(){
$new=$this->index_com($k);
//输出指定的值
echo$new;
}
publicfunctionindex_com($k){
$arr=['list'=>a,'category'=>'c'];
return$arr[$k];
