php二维数组 遍历

上面的代码确实没搞清楚到底要做什么。 二维数组可以直接用foreach遍历即可。 public function index(){ $as=D(Userfile); $re= $as->limit(0, 10)->select(); $arr = array(); $i=0; $a=0; var_dump($re); if(!empty($re)){ foreach($re as $v)...

?php//使用for循环遍历$arr2=array(array("张三","20","男"),array("李四","25","男"),array("王五","19","女"),array("赵六","25","女"));echo "姓名年龄

如果重复怎么处理?是否需要做区分? 如果忽略重复和反向还原,那么直接用array_merge即可 $new_arr = array_merge($arr['1'],$arr[2]); foreach: foreach($arr as $v=>$k){ foreach($v as $val=>$key){ $new_arr[$key] = $val; }}

foreach($arr as $key=>$value){ $arr[$key]['age']=55 } 看你的需求 这就行了

这样,已经确定了uptime这个键名在第二维是吧 使用foreach ($array as &$arr){ $arr['uptime'] = date('Y-m-d', strtotime($arr['uptime'])); }

foreach($list as &$one){ $goushi = $one['goushi']; }

php $employee[]=array("jas,join","programmer",20); $employee[]=array("june,join","programmer",20); $employee[]=array("aili,join","programmer",20); $employee[]=array("doe,jane","programmer",20); $newname = array(); foreach ($emp...

stdClass Object(。。。。)这是一个对象,你可以这样 foreach ($parame as $key => $val){ $b=$val->a; $c=$val->b; $d=$val->c; }

$b=array();//空数组foreach ($arr as $a){ $b[]=$a['100864'];//添加值}print_r($b);

echo get_all($arr); function get_all($arr){ $count = count($arr); for($i=0;$i
