php 2个一维数组合并为1个二维数组，

php 2个一维数组合并为1个二维数组，一个数组作为键，另一个作为值：数据是动态从数据库中读取出来的：第一个数组格式如下：  $arr1 = array(1=>'餐饮美食',2=>'休闲娱乐',3=>'美容化妆',4=>"网上购物",5=>'运动健身',6=>'其他分类'); 第二个数组格式如下：  $str2 = Array(

你应该还有很多个$arr2格式的数组，不知道你是将这些存在一个大数组里还是单个个的，反正我想你这里$arr2的'tuanid'指的是$arr1里的索引值吧，根据索引id找到对应的类似$arr2数组，然后按上面代码差不多意思改改就好了
array_combine(array1,array2)
函数通过合并两个数组来创建一个新数组，其中的一个数组是键名，另一个数组的值为键值。如果其中一个数组为空，或者两个数组的元素个数不同，则该函数返回 false。其中array1 是规定的键名，array2 则为值
上面几位都测试了下，还没有成功，还有因为两个数组键不相同，这个array_combine(array1,array2)用不了，
$arr1 数组数据结构：
$arr2 数组数据结构：
想实现如下：$arr1和$arr2合并为一个新数组，新数组以$arr1的值为键，以$arr2为值，就是把$arr2中属于$arr1每个分类的数据中前几条列出来，如下：array(  '餐饮美食'=>array(              '0'=>array(                   'tuanid'=>1,                   'webname'=>'百度'                   );
              '1'=>array(                   'tuanid'=>90,                   'webname'=>'谷歌'                   );
              '2'=>array(                   'tuanid'=>123,                   'webname'=>'腾讯'                   );              );  '休闲娱乐'=>array(              '0'=>array(                   'tuanid'=>20,                   'webname'=>'百度'                   );
              '1'=>array(                   'tuanid'=>61,                   'webname'=>'谷歌'                   );
              '2'=>array(                   'tuanid'=>92,                   'webname'=>'腾讯'                   );              ););
不对应就改为对应不就得了
array_combine(array_values(array1),array2)
像三楼那样写不就行了吗   $arr2 = array(array(),array(),array(),array（）)
