只列出了三个...
然后循环查询对应该数字出来
如

LTC    70.85         66.51    .....等
BTC   10759.5     10272.24 ...等
ETH   182.66       174.5  .......等
数据是JSON格式
foreach怎么写.最好贴完整的哈..复制上去就可以使用

好的，我先去学一下php, 回头告诉你。

1. <?php
   
2. $str = '[{"from":"LTC","high":70.85,"low":66.51,"buy":67.98,"sell":68.05,"last":67.98,"vol":1395013.1448474,"change":2.17,"trend":0},{"from":"BTC","high":10759.5,"low":10272.24,"buy":10480.69,"sell":10485,"last":10485,"vol":29601421.442734,"change":1.71,"trend":0},{"from":"ETH","high":182.66,"low":174.5,"buy":177.44,"sell":177.58,"last":177.44,"vol":5469242.8201616,"change":0.38,"trend":0}]';
   
3. $data = json_decode($str, true);
   
4. foreach ($data as $val) {
   
5.     echo implode($val, ' ') . PHP_EOL;
   
6. }

不会PHP，直接写个实体类，然后解析这个JSON即可

采集的虚拟货币交易所的数据吧，来时时更新自己的交易平台？？

直接解析JSON数组就可以了吧，然后直接调用LTC之些数据啊，还要什么循环？？

感谢各位.就是一个这个东西方便网友查看

数据不全.只是某一个平台的.还有几个平台.暂时没有集在一起.以我能力目前有点难度.以后再慢慢补全吧
没有存数据库.只是存在文档里.直接读取..
