为什么回显资源ID#4
而不是页面本身?
Why does it echo Resource id #4
instead of the page itself?
推荐答案
因为fopen返回一个指向文件的resurce指针,而不是文件的内容。它只是打开它以便随后读取和/或写入,取决于您打开文件的模式。
Because fopen returns a resurce pointer to the file, not the content of the file. It simply opens it for subsequent reading and/or writing, sependent on the mode in which you opened the file.
您需要fread()来自引用的资源的数据在$ handle。
You need to fread() the data from the resource referenced in $handle.
这是你可以在php.net的手册页上自己阅读的所有基本内容
This is all basic stuff that you could have read for yourself on the manual pages of php.net
