标签： php arrays json

我有一个json文件。

使用foreach循环在Array中解码之后，它看起来像这样：

现在我如何解析和显示CategoryName的nodeName。

2 个答案:

答案 0 :(得分：0)

CategoryName内容不是任何标准格式，如Dark Absol说的Niet。

这是一种获取Node ID＆amp; amp;分类名称。我担心这不是最好的方法，但我想说它只是为了帮助你。

答案 1 :(得分：0)

对于某些RegExps，您可以将String转换为正确的json格式，然后对其进行解码：

PHP代码 

$json = '{"GetProductsByCategoryResult":[{"Brand":"Bohra","CategoryName":"[[{nodeId=20001, nodeName=FLIPKART_TREE}, {nodeId=20007, nodeName=Electronics}, {nodeId=20268, nodeName=Appliances}, {nodeId=20098, nodeName=Kitchen Appliances}, {nodeId=20110, nodeName=Electric Jug(heater)\/Travel Kettles}]]","CategoryPathAsString":"Root|[[{nodeId=20001, nodeName=FLIPKART_TREE}, {nodeId=20007, nodeName=Electronics}, {nodeId=20268, nodeName=Appliances}, {nodeId=20098, nodeName=Kitchen Appliances}, {nodeId=20110, nodeName=Electric Jug(heater)\/Travel Kettles}]]|","Colour":null,"Custom1":"40","Custom2":"0","Custom3":null,"Custom4":null,"Custom5":null,"DiscountedPrice":0.00,"Location":null,"MID":678106,"MPN":null,"MerchantName":"Flipkart","PID":13653,"ProductDescription":"Ideal for boiling water, maggie this electric kettle from Bohra Mrketing is a necessity for every household.","ProductID":123802338,"ProductImageLargeURL":"http:\/\/img5a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-400x400-imae4dcyxpvrbqbu.jpeg;http:\/\/img5a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-75x75-imae4dcyxpvrbqbu.jpeg;http:\/\/img6a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-275x275-imae4dcyxpvrbqbu.jpeg;http:\/\/img5a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-125x125-imae4dcyxpvrbqbu.jpeg;http:\/\/img6a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-40x40-imae4dcyxpvrbqbu.jpeg;http:\/\/img6a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-original-imae4dcyxpvrbqbu.jpeg;http:\/\/img5a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-1100x1100-imae4dcyxpvrbqbu.jpeg;http:\/\/img6a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-100x100-imae4dcyxpvrbqbu.jpeg;http:\/\/img6a.flixcart.com\/image\/electric-kettle\/w\/n\/h\/bohra-bht013-rose-200x200-imae4dcyxpvrbqbu.jpeg;","ProductImageMediumURL":null,"ProductImageSmallURL":null,"ProductName":"Bohra Bht013 Rose 1 L Electric Kettle","ProductPrice":1599.00,"ProductPriceCurrency":"INR","ProductSKU":"EKTE73GBRPMVYWNH","ProductURL":"http:\/\/clk.omgt5.com\/?AID=861823&PID=13653&Type=12&r=http:\/\/dl.flipkart.com\/dl\/bohra-bht013-rose-1-l-electric-kettle\/p\/itme73gbhjxf5hty%3Fpid%3DEKTE73GBRPMVYWNH","StockAvailability":"In stock","WasPrice":2700.00}]}';

$obj = json_decode($json);

$str = $obj->{'GetProductsByCategoryResult'}[0]->{'CategoryName'};

$obj->{'GetProductsByCategoryResult'}[0]->{'CategoryName'} = json_decode( '[' . preg_replace( ['/([^=\[\],\s\{\}]+)=([^=\[\],\{\}]+)/', '/(Root|\||\[|\])/'], ['"$1":"$2"'], $str ) . ']' );

CategoryName属性将具有此值：

CategoryName的值： 

Array
(
    [0] => stdClass Object
        (
            [nodeId] => 20001
            [nodeName] => FLIPKART_TREE
        )

    [1] => stdClass Object
        (
            [nodeId] => 20007
            [nodeName] => Electronics
        )

    [2] => stdClass Object
        (
            [nodeId] => 20268
            [nodeName] => Appliances
        )

    [3] => stdClass Object
        (
            [nodeId] => 20098
            [nodeName] => Kitchen Appliances
        )

    [4] => stdClass Object
        (
            [nodeId] => 20110
            [nodeName] => Electric Jug(heater)/Travel Kettles
        )

)

Ideone Example

使用相同的RegExp，您还可以解码CategoryPathAsString属性：

可选的PHP代码 

$str = $obj->{'GetProductsByCategoryResult'}[0]->{'CategoryPathAsString'};

$obj->{'GetProductsByCategoryResult'}[0]->{'CategoryPathAsString'} = json_decode( '[' . preg_replace( ['/([^=\[\],\s\{\}]+)=([^=\[\],\{\}]+)/', '/(Root|\||\[|\])/'], ['"$1":"$2"'], $str ) . ']' );
