版主啊，麻烦你再看下啊：
php里写了：
require_once ('src/jpgraph.php');
require_once ('src/jpgraph_bar.php');
这2个文件都在：
c:\program files (x86)\easyphp-12.1\php\jpgraph\src里.
然后php.ini里，原来是这样的：
; windows: \path1;\path2
;include_path = .;${path}\php\includes
;
可不管我哦这么改，像：
; windows: \path1;\path2
;include_path = ;${path}\php\includes; c:\program files (x86)\easyphp-12.1\php\jpgraph
或
; windows: \path1;\path2
;include_path = ;${path}\php\includes; c:\program files (x86)\easyphp-12.1\php\jpgraph、scr
都是报这2个错！！！！
warning: require_once(src/jpgraph.php): failed to open stream: no such file or directory in c:\program files (x86)\easyphp-12.1\www\formulaire\reponse_formulaire_systemb_1.php on line 13
fatal error: require_once(): failed opening required 'src/jpgraph.php' (include_path='.;c:\php\pear') in c:\program files (x86)\easyphp-12.1\www\formulaire\reponse_formulaire_systemb_1.php on line 13
到底咋回事啊？
;include_path = 这里到底要咋写啊，我头都大好几圈了.多谢指教啊，永世不忘.
