在PHP中可以使用递归的方法将多维数组的键名和键值进行替换,其具体替换键名和键值的代码方法为“function changeKeys($array, $keyEnArray, $keyZhCnArray){...}”。

PHP递归多维数组替换键名和键值

多维数组键名替换

在很多时候获取到的数组结果不尽人意,需要自己修改后才能的到一个满足需求的数组,这是后可以通过递归的方式修改键名

代码如下

替换键名的代码,例如:

function changeKeys($array, $keyEnArray, $keyZhCnArray)
{
    if(!is_array($array)) return $array;
    $tempArray = array();
    foreach ($array as $key => $value){
        // 处理数组的键,翻译成中文
        $key = array_search($key, $keyEnArray, true) === false ? $key : $keyZhCnArray[array_search($key, $keyEnArray)];
        if(is_array($value)){
            $value = changeKeys($value, $keyEnArray, $keyZhCnArray);
        }
        $tempArray[$key] = $value;
    }
    return $tempArray;
}
$info = array( "fruits" => array("apple", "banana", "pear"), "furniture" => array("table", "chair", "bed"));
$keyEnArray = array("fruits" , "furniture");
$keyZhCnArray = array("水果" , "家具");
$result = changeKeys($info, $keyEnArray, $keyZhCnArray);
print_r($result);

多维数组键值替换

在很多时候获取到的数组结果不尽人意,需要自己修改后才能的到一个满足需求的数组,这是后可以通过递归的方式修改键值

代码如下

替换键值的代码,例如:

// 递归改变数组的键值
function changeValues($array, $valueEnArray, $valueZhCnArray)
{
    if(!is_array($array)) return $array;
    $tempArray = array();
    foreach ($array as $key=>$value){
        if(is_array($value)){
            $value = changeValues($value, $valueEnArray, $valueZhCnArray);
        }else{
            // 处理数组的值,翻译成中文
            $value = array_search($value, $valueEnArray, true) === false ? $value : $valueZhCnArray[array_search($value, $valueEnArray)];
        }
        $tempArray[$key]=$value;
    }
    return $tempArray;
}
$info = array( "fruits" => array("apple", "banana", "pear"), "furniture" => array("table", "chair", "bed"));
$valueEnArray = array("apple" , "banana", "pear", "table", "chair", "bed");
$valueZhCnArray = array("苹果" , "香蕉" ,"梨", "桌子", "椅子", "床");
$result = changeValues($info, $valueEnArray, $valueZhCnArray);
print_r($result);
