老师关于PHP数组的有关问题

<br />                //定义日期数组<br />                $search_date=array();<br />		//进入FOR循环，从开始时间循环到结束时间<br />                //转化为UNIX时间戳进行操作<br />		for($i=strtotime($start_time);$i<strtotime($stop_time)+86400;$i+=86400)<br />		{<br />                    $search_date_num =  date('Y-m-d', $i);<br />                    $search_date[]= $search_date_num;<br />		}<br />

<br />Array ( <br />[0] => 16777221 <br />[1] => 16777222  ) <br />Array ( <br />[0] => 16777221 <br />[1] => 16777222  ) 

$newArr= array();<br />$search_date = array(0=>'2014-08-10' ,1=>'2014-08-11');<br />$num = 0;<br />foreach ($search_date as $k => $v){<br />    $newArr[$num][$k] = $v;<br />    $num++;<br />}<br />var_dump($newArr);
