如何在PHP中将数组的json值解码到数组中
我有一个json文件如何在PHP中将数组的json值解码到数组中,php,arrays,json,Php,Arrays,Json,我有一个json文件 { "GetProductsByCategoryResult":[ { "Brand":"Bohra", "CategoryName":"[[{nodeId=20001, nodeName=FLIPKART_TREE}, {nodeId=20007, nodeName=Electronics}, {nodeId=20268, nodeName=Appliances}, {nodeId=20098, nodeName=Ki

现在，我如何单独解码和显示CategoryName的节点名。CategoryName内容并不像Niet the Dark Absol所说的那样是任何标准格式
下面是获取节点ID和类别名称的方法。恐怕这不是最好的办法，但我想说这只是为了帮助你

使用一些regexp
可以将字符串
转换为正确的json
格式，然后对其进行解码：

CategoryName
属性将具有以下值：
类别名称的值：

使用相同的RegExp
还可以解码CategoryPathAsString
