Question

从数据库中检索数据：

$db = array (
    0 => 
    array (
      'stay' => '10',
      'end' => '2015-12-29',
      'start' => '2015-12-20',
      'pid' => '231096236',
      'normal_price' => '385',
      'promo_price' => '385',
      'resell_price' => '385',
    ),
    1 => 
    array (
      'stay' => '7',
      'end' => '2016-01-05',
      'start' => '2015-12-30',
      'pid' => '231096235',
      'normal_price' => '385',
      'promo_price' => '385',
      'resell_price' => '385',
    ),
    2 => 
    array (
      'stay' => '3',
      'end' => '2053-01-01',
      'start' => '2016-01-06',
      'pid' => '231096234',
      'normal_price' => '385',
      'promo_price' => '385',
      'resell_price' => '385',
    ),
  ),

要合并的新数组：

$new = array (
    0 => 
    array (
      'stay' => '2',
      'end' => '2015-07-01',
      'start' => '2015-06-03',
      'normal_price' => '145',
      'promo_price' => '145',
      'resell_price' => '135',
    ),
    1 => 
    array (
      'stay' => '4',
      'end' => '2015-07-05',
      'start' => '2015-07-02',
      'pid' => '231096235',
      'normal_price' => '100',
      'promo_price' => '100',
      'resell_price' => '100',
    ),
    2 => 
    array (
      'stay' => '4',
      'end' => '2015-09-03',
      'start' => '2015-07-06',
      'pid' => '231096236',
      'normal_price' => '100',
      'promo_price' => '100',
      'resell_price' => '100',
    ),
  ),

预期结果：

$expected = array (
    0 => 
    array (
      'stay' => '2',
      'end' => '2015-07-01',
      'start' => '2015-06-03',
      'normal_price' => '145',
      'promo_price' => '145',
      'resell_price' => '135',
    ),
    1 => 
    array (
      'stay' => '4',
      'end' => '2015-07-05',
      'start' => '2015-07-02',
      'pid' => '231096235',
      'normal_price' => '100',
      'promo_price' => '100',
      'resell_price' => '100',
    ),
    2 => 
    array (
      'stay' => '4',
      'end' => '2015-09-03',
      'start' => '2015-07-06',
      'pid' => '231096236',
      'normal_price' => '100',
      'promo_price' => '100',
      'resell_price' => '100',
    ),
    3 => 
    array (
      'stay' => '3',
      'end' => '2053-01-01',
      'start' => '2016-01-06',
      'pid' => '231096234',
      'normal_price' => '385',
      'promo_price' => '385',
      'resell_price' => '385',
    ),
  ),

到目前为止的结果：

$merge = array (
    0 => 
    array (
      'stay' => '2',
      'end' => '2015-07-01',
      'start' => '2015-06-03',
      'normal_price' => '145',
      'promo_price' => '145',
      'resell_price' => '135',
    ),
    1 => 
    array (
      'stay' => '4',
      'end' => '2015-07-05',
      'start' => '2015-07-02',
      'pid' => '231096235',
      'normal_price' => '100',
      'promo_price' => '100',
      'resell_price' => '100',
    ),
    2 => 
    array (
      'stay' => '4',
      'end' => '2015-09-03',
      'start' => '2015-07-06',
      'pid' => '231096236',
      'normal_price' => '100',
      'promo_price' => '100',
      'resell_price' => '100',
    ),
  ),

这些是要求：

如果新数组中的记录没有pid（价格ID）那么它就是被视为新数据。（记录开始时间：2015-06-03并结束： 2015年6月3日）
如果新数组中的记录具有pid并且与表中的记录之一匹配，则新记录的值将覆盖旧记录（记录为pid：231096235和pid：231096236）
如果来自数据库的记录有pid并且与新数组中的任何pid不匹配，那么它应该被添加到新数组中（它应该用pid记录：231096234）

我的职能：

$merge = array();
foreach ($new as $ikey => $ival) {
    $ispid = (isset($ival['pid'])) ? (int) $ival['pid'] : 0;
    if ($ispid === 0) {
        $merge[] = $ival;
    }
    if ($ispid > 0) {
        $exist = false;
        foreach ($db as $rkey => $rval) {
            $rspid = (int) $rval['pid'];
            if ($ispid === $rspid) {
                $spid_exist = true;
                overridePriceValue($ival, $rval);
                $merge[] = $rval;
            }
        }
//        if ($exist === false) {
//            echo "price id " . $ispid . " is not match with any special prices.";
//        }
    }
}

function overridePriceValue($input_spc_price, &$spc_price) {
    if (isset($input_spc_price['stay'])) {
        $spc_price['stay'] = $input_spc_price['stay'];
    }
    if (isset($input_spc_price['end'])) {
        $spc_price['end'] = $input_spc_price['end'];
    }
    if (isset($input_spc_price['start'])) {
        $spc_price['start'] = $input_spc_price['start'];
    }
    if (isset($input_spc_price['normal_price'])) {
        $spc_price['normal_price'] = $input_spc_price['normal_price'];
    }
    if (isset($input_spc_price['promo_price'])) {
        $spc_price['promo_price'] = $input_spc_price['promo_price'];
    }
    if (isset($input_spc_price['resell_price'])) {
        $spc_price['resell_price'] = $input_spc_price['resell_price'];
    }
}

我需要你的建议来实现目标。谢谢:)）
