运行时出现下面的错误:
Fatal error: Uncaught exception 'com_exception' with message 'Error [0x80070057] 参数不正确。 ' in D:\WAMP\WWW\index.php:11 Stack trace: #0 D:\WAMP\WWW\index.php(11): com->Register('EducationGameRe...', 'GameRegister', 'i=sss', 'f=s', 'r=l') #1 {main} thrown in D:\WAMP\WWW\index.php on line 11
初次接触PHP,大家帮我看一下,谢谢了!
------解决方案--------------------原型要求参数是指针,而 com 是不能传递指针的
------解决方案-------------------- $ch = $dw->GameRegister("P2G9YFWGZW68G","2597367cea95b2cf0aace3bd5059c33e",$reg_code);
這樣試試
