怎么循环带条件的数组

<br>$abc=array(     <br>[navigation_list] => Array<br>        (<br>            [0] => Array<br>                (<br>                    [navigation_id] => 1<br>                    [navigation_title] => 题目1<br>                    [navigation_link] => http://127.0.0.1/<br>                    [navigation_sort] => 255<br>                    [navigation_open_type] => 1<br>                )<br><br>            [1] => Array<br>                (<br>                    [navigation_id] => 2<br>                    [navigation_title] => 题目2<br>                    [navigation_link] => http://127.0.0.1/circle<br>                    [navigation_sort] => 255<br>                    [navigation_open_type] => 1<br>                )<br><br>            [2] => Array<br>                (<br>                    [navigation_id] => 3<br>                    [navigation_title] => 题目3<br>                    [navigation_link] => http://127.0.0.1/microshop<br>                    [navigation_sort] => 255<br>                    [navigation_open_type] => 1<br>                )<br><br>            [3] => Array<br>                (<br>                    [navigation_id] => 4<br>                    [navigation_title] => 题目4<br>                    [navigation_link] => http://127.0.0.1/shop/index.php?act=brand<br>                    [navigation_sort] => 255<br>                    [navigation_open_type] => 1<br>                )<br><br>        )<br>)<br>
