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
------解决思路----------------------

$a = array(<br />  array(<br />    'province'=>'ss',<br />    'package' => array(<br />      array(<br />        'FX58'=>0,<br />        'PName' => 'a'<br />      ),<br />    ),<br />    'storeName'=> 'test',<br />  ),<br />  array(<br />    'province'=>'cc',<br />    'package' => array(<br />      array(<br />        'FX58'=>1,<br />        'PName' => 'b'<br />      ),<br />    ),<br />    'storeName'=> 'test2',<br />  )<br />);<br />$b = array(<br />  array(<br />    'province'=>'ss',<br />    'package' => array(<br />      array(<br />        'FX58'=>1,<br />        'PName' => 'a'<br />      ),<br />    ),<br />    'storeName'=> 'test',<br />  ),<br />  array(<br />    'province'=>'cc',<br />    'package' => array(<br />      array(<br />        'FX58'=>2,<br />        'PName' => 'b'<br />      ),<br />    ),<br />    'storeName'=> 'test2',<br />  )<br />);<br /><br />foreach($a as $v) {<br />  foreach($v['package'] as $t) {<br />    $res[$v['province']][$v['storeName']][$t['PName']] = $t['FX58'];<br />  }<br />}<br />foreach($b as &$v) {<br />  foreach($v['package'] as $t) {<br />    $res[$v['province']][$v['storeName']][$t['PName']] += $t['FX58'];<br />  }<br />}<br />foreach($a as &$v) {<br />  foreach($v['package'] as &$t) {<br />    $t['FX58'] = $res[$v['province']][$v['storeName']][$t['PName']];<br />  }<br />}<br /><br />print_r($a);<br />
