PHP数据导出和WEB service的有关问题
PHP数据导出和WEB service的问题
问题1：用PHPExcel导出数据到excel，大概有7000行记录的时候，就不行了，但是我大概要达到的效果是能导出2、3万行记录，这个该怎么解决呢？
问题2：我用nusoap写得web service，本地测试时能够正常使用，但是上传到服务器上的时候，返回的json值都是空的，显示：HTTP Error: no data present after HTTP headers，返回string的时候是正常的，这个是什么问题呢？
我语文水平比较差，也刚开始用PHP编程，有说不清楚的地方大家指出，我再回帖说明，在线等待大神解答。。。
------解决方案--------------------
excel 有个最大行限制吧？没记错的话 所以这个2-3万行恐怕应该是不行的.
这个你看看是不是内存已经给占完了
第2个问题不太清楚.
------解决方案--------------------
HTTP Error: no data present after HTTP headers
是说在 http 头后面没有数据，但是在头中声明了数据长度
可能是字符集导致 json 编码失败，或许是 nusoap 的问题
SOAP 是使用 XML 做载体
你用 json 做载体就有点不伦不类了
使用 json 作载体的是 REST
