用于在多维数组中搜索值的函数

Question

我得到了第一个(Main)数组，如下所示：

$groceritems = array(
        "apple" => array(
                "price"=>"10",
                "origin"=>array("australia","belgium","USA","canada"),
                "breed"=>array("gala","fuji","Honeycrisp","washington"),),

        "orange" => array(
                "price"=>"10",
                "origin"=>array("australia","belgium","USA","canada"),
                "breed"=>array("gala","fuji","Honeycrisp","washington"),

        ),
);
foreach ($groceritems as $key => $value) {
    $origins = $value['origin'];
    $breeds= $value['breed'];

    foreach (array_combine($origins, $breeds) as $origin=>$breed) { 

echo $breed ." ".$key." from ". $origin ." price is RM ". $value['price'];

        echo "<br>";    

    }


}

第二个数组如下所示，

$grocer= array(


"apple" => array( "country"=>"australia",
                  "newprice"=>"50",
                  "breed"=>"gala"),


"orange" => array("country"=>"belgium",
                  "newprice"=>"30",
                   "breed"=>"gala"),


);

我可以循环第一个数组，但如何将第一个数组的价格(在foreach循环中)替换为包含类别(橙色/苹果)、国家和品种匹配的第二个数组的新价格？就像下面的结果，

澳洲嘎拉苹果售价50马币

比利时富士苹果售价10马币

来自美国的蜜脆苹果售价10马币

来自加拿大的华盛顿苹果价格为10马币。

澳大利亚的gala橙子价格是10马币。

比利时产的富士橙子10马币。

来自美国的蜜糖橙售价10马币。

来自加拿大的华盛顿橙子的价格是10马币。

要获得所需的结果，请执行以下操作

$groceritems = array(
    "apple" => array(
        "price"=>"10",
        "origin"=>array("australia","belgium","USA","canada"),
        "breed"=>array("gala","fuji","Honeycrisp","washington"),),

    "orange" => array(
        "price"=>"10",
        "origin"=>array("australia","belgium","USA","canada"),
        "breed"=>array("gala","fuji","Honeycrisp","washington"),

    ),
);

$grocer= array(
    "apple" => array( "country"=>"australia",
        "newprice"=>"50",
        "breed"=>"gala"),


    "orange" => array("country"=>"belgium",
        "newprice"=>"30",
        "breed"=>"gala"),
);

foreach ($groceritems as $key => $value) {
    $origins = $value['origin'];
    $breeds= $value['breed'];

    foreach (array_combine($origins, $breeds) as $origin=>$breed) {

        if(isset($grocer[$key]) && $origin == $grocer[$key]['country'] && $breed == $grocer[$key]['breed'] ){
            $price =  $grocer[$key]['newprice'];
        } else {
            $price = $value['price'];
        }

        echo $breed ." ".$key." from ". $origin ." price is RM ". $price;

        echo "<br>";

    }
}
