json数组和php数组转换

json数组

1.表示方式

JSON(JavaScript Object Notation) 是一种轻量级的数据交换格式，主要用于数据格式交换。

json表示 方式为"{名称/**属性标示* */：值 }" 例如：{ "SchoolName": "江汉大学","Location":"武汉" }

php中 $test='{ "SchoolName": "江汉大学" ，"Location":"武汉"}';

js 中var test = { "SchoolName": "江汉大学" ，"Location":"武汉" };

2.二维数组

js中

var test=

{

'totalCount':6,

'root':

[

{'dates':'0','amounts':'0'},

{'dates':'2','amounts':'1'},

{'dates':'4','amounts':'1.5'},

{'dates':'6','amounts':'1.8'},

{'dates':'8','amounts':'1.9'},

{'dates':'10','amounts':'13'}

]

};

php中 方式一

$test=

‘{

'totalCount':6,

'root':

[

{'dates':'0','amounts':'0'},

{'dates':'2','amounts':'1'},

{'dates':'4','amounts':'1.5'},

{'dates':'6','amounts':'1.8'},

{'dates':'8','amounts':'1.9'},

{'dates':'10','amounts':'13'}

]

}’;字符串赋给php变量后，通过json_encode($test)可以转换为json数组
