1.php:
.....
include(co.php);
echo ..
...

2.php:
.....
include(co.php);
echo ..
...


请教高手一个问题

对于在co.php申明的变量当co.php被其他文件(这里是1.php和2.php)include时,是不是每次都会再重新申明同样名称的变量?还是co.php先申明此变量后其他文件就可以直接用此变量了?


回复讨论(解决方案)

可以看做  在include  的位置 直接写入 include内的代码

每次都会再重新申明同样名称的变量

能直接用,include,就等于把那文件的内容写到include那处

那我想申明一个变量好后其它php文件可以直接使用此变量应该怎么操作呢?

include 后,直接引用就是了。
