怎么在两个PHP文档中传递值
如何在两个PHP文档中传递值
在一个PHP文档的函数中计算出来一个中间值,在另一个PHP文件的函数中用到这个中间值,请教,我怎样才能够实现这个中间值在不同文档间的传递?
------解决方案--------------------
这两个文档有什么关系?
常用的有: post/get/cookie/session............等.
------解决方案--------------------
在一个PHP文档A的函数A中计算出来一个中间值,在另一个PHP文件B的函数B中用到这个中间值
则有:PHP文档C
include 'PHP文档A';
include 'PHP文档B';
$v = 函数B(函数A());
------解决方案--------------------
实在不会 就用最笨的办法
引用一个公用函数
用的时候就再算一遍吧
------解决方案--------------------
用 session 安全一些
------解决方案--------------------
这里面有个疑问就是如果B文档包含A文档,那么A文档中的全局变量是不同时是A文档中的全局变量?
是的,变量/函数直接可在B访问
你的情况可以直接用include,或者用session/cookie 也可以。
