return多個值的引用方法

輸出指定的值,除了索引方式還有其它方式嗎？

public function index(){    $new = $this->index_com();    //輸出指定的值    echo $new[2];}public function index_com(){    $list = 'a';    $category = 'b';    $totalCount = 'c';    $current = 'd';    return array($list, $category, $totalCount, $current);}

public function index(){    $new = $this->index_com();    //輸出指定的值    echo $new[2];}public function index_com(){    $list = 'a';    $category = 'b';    $totalCount = 'c';    $current = 'd';    return array($list, $category, $totalCount, $current);}

還可以是字典，

public function index(){    $new = $this->index_com();    //輸出指定的值    echo $new[list];}public function index_com(){    $list       = 'a';    $category   = 'b';    $totalCount = 'c';    $current    = 'd';    return array('list'=>$list, 'category'=>$category);}

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

使用list文法可以達到你想要的效果：

public function index(){   list($list, $category, $totalCount, $current) = $this->index_com();   //輸出指定的值   echo $category;}public function index_com(){    $list = 'a';    $category = 'b';    $totalCount = 'c';    $current = 'd';    return array($list, $category, $totalCount, $current);}
