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

回复讨论(解决方案)

这样？

$new=array_merge($a,$b);echo "<pre class="prettyprint linenums">";print_r($new);echo "

“;

分组键是哪个？

这样？

$new=array_merge($a,$b);echo "<pre class="prettyprint linenums">";print_r($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

$a = array(  array(    'province'=>'ss',    'package' => array(      array(        'FX58'=>0,        'PName' => 'a'      ),    ),    'storeName'=> 'test',  ),  array(    'province'=>'cc',    'package' => array(      array(        'FX58'=>1,        'PName' => 'b'      ),    ),    'storeName'=> 'test2',  ));$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',  ));foreach($a as $v) {  foreach($v['package'] as $t) {    $res[$v['province']][$v['storeName']][$t['PName']] = $t['FX58'];  }}foreach($b as &$v) {  foreach($v['package'] as $t) {    $res[$v['province']][$v['storeName']][$t['PName']] += $t['FX58'];  }}foreach($a as &$v) {  foreach($v['package'] as &$t) {    $t['FX58'] = $res[$v['province']][$v['storeName']][$t['PName']];  }}print_r($a);
