例如
$a = array(
  array(
    'province'=>'ss',
    'package' => array(
      array(
        'fx58'=>0,
        'pname' => 'a'
      ),
    ),
    'storename'=> 'test',
  ),
  array(
    'province'=>'cc',
    'package' => array(
      array(
        'fx58'=>1,
        'pname' => 'b'
      ),
    ),
    'storename'=> 'test2',
  )
);
$b = array(
  array(
    'province'=>'ss',
    'package' => array(
      array(
        'fx58'=>1,
        'pname' => 'a'
      ),
    ),
    'storename'=> 'test',
  ),
  array(
    'province'=>'cc',
    'package' => array(
      array(
        'fx58'=>2,
        'pname' => 'b'
      ),
    ),
    'storename'=> 'test2',
  )
);
将b数组值统计到a数组中
回复讨论(解决方案) 这样？
$new=array_merge($a,$b);echo ;print_r($new);echo

;
分组键是哪个？
这样？
$new=array_merge($a,$b);echo ;print_r($new);echo

;
额 我需要的是将相同province,storename,，pname中fx158数据统计起来
分组键是哪个？
将相同province,storename,，pname中fx158数据统计起来
