php 遍历二维数组

?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

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

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...

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; }}

这能遍历吗,这样的形式只能直接写死了吧。感觉你的数组要重新组合一下,题目为一级数组,选项为二级数组

一般不知道一维数组的键名情况下,用两个foreach 不过项目中基本都是知道一维数组的键名的 所以一般是 foreach( $data['iamge'] as $key => $val ) { echo $val; }

foreach ( $firstArray as $item ){ if ( $item['name'] != '' ){ $result[] = $item; } } return $result;

直接两个 foreach 是不符合楼主的需求的。 $arr=Array( array('123332' => '123332','123333' => '123333'), array('123332' => 'Hockey Stick','123333' => 'Hockey Stick2'), array('123332' => 33.25 , '123333' => 33.25));//$arr 为你要查...

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'])); }
