求高效算法,合并多个多维数组值
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
