json数据加密php sojson加密

php解析json数组问题。

$a = json_decode('{"status":0,"total":1,"size":1,"contents":[{"title":"111","location":[113.11509,23.012777],"city":"\u4f5b\u5c71\u5e02","create_time":1385386545,"geotable_id":38432,"address":"\u5e7f\u4e1c\u7701\u4f5b\u5c71\u5e02\u7985\u57ce\u533a\u6c7e\u6c5f\u5357\u8def8\u53f7","province":"\u5e7f\u4e1c\u7701","district":"\u7985\u57ce\u533a","map_id":"1","uid":42504634,"coord_type":3,"type":0,"distance":370,"weight":0}]}',true);

json_decode第二个参数true

解析出来就是array(4) { ["status"]= int(0) ["total"]= int(1) ["size"]= int(1) ["contents"]= array(1) { [0]= array(14) { ["title"]= string(3) "111" ["location"]= array(2) { [0]= float(113.11509) [1]= float(23.012777) } ["city"]= string(9) "佛山市" ["create_time"]= int(1385386545) ["geotable_id"]= int(38432) ["address"]= string(43) "广东省佛山市禅城区汾江南路8号" ["province"]= string(9) "广东省" ["district"]= string(9) "禅城区" ["map_id"]= string(1) "1" ["uid"]= int(42504634) ["coord_type"]= int(3) ["type"]= int(0) ["distance"]= int(370) ["weight"]= int(0) } } }

这样的数组会取内容了吧

php 使用json加密的一个问题

用正则替换

$string='{"id":"2","username":"test","email":"123@qq.com","logintime":null,"loginip":null,"status":"0"}';

$new_str=preg_replace('/"([a-z]+)"\:/','\1:',$string);

输出$new_str是去掉了key键的引号:

{id:"2",username:"test",email:"123@qq.com",logintime:null,loginip:null,status:"0"}

PHP解密Unicode及Escape加密字符串

在json中不支持中文,用它传送中文数据就会出现数据丢失或者乱码,必须在传送前对要发送的字符串进行编码,由于传送过去需要用js进行数据解析,考虑

到js中有unescape函数,故若在php中有个escape函数,对数据进行编码,在客户端用unescape进行

解码,这样就会方便很多。

在网上搜索一把,很多用php实现的escape函数,大同小异
