PHP调用C++DLL的问题

用DynamicWrapper方法调用。下载DynamicWrapper.dll到php ext下与windows system32下， $dw = new COM("DynamicWrapper"); $dw-Register("EbUsbApi.dll", "EbCreateDataFile", 'i=sls', "f=s", "r=l"); $ch = $dw-EbCreateDataFile("222",11,"22"); i=descri

用DynamicWrapper方法调用。下载DynamicWrapper.dll到php ext下与windows system32下，
$dw = new COM("DynamicWrapper");
$dw->Register("EbUsbApi.dll", "EbCreateDataFile", 'i=sls', "f=s", "r=l");
$ch = $dw->EbCreateDataFile("222",11,"22");

i=describes the number and data type of the functions parameters

f=type of call _stdcall or _cdecl. So it can work with both MS C++ and Borland C++. Default to _stdcall. If that doesn't work use _cdecl. If that doesn't work good luck!

r=return data type.

Data types are:

const ARGTYPEINFO ArgInfo[] =
{
{'a', sizeof(IDispatch*), VT_DISPATCH}, // a IDispatch*
{'c', sizeof(unsigned char), VT_I4}, // c signed char
{'d', sizeof(double), VT_R8}, // d 8 byte real
{'f', sizeof(float), VT_R4}, // f 4 byte real
{'k', sizeof(IUnknown*), VT_UNKNOWN}, // k IUnknown*
{'h', sizeof(long), VT_I4}, // h HANDLE
{'l', sizeof(long), VT_I4}, // l long
{'p', sizeof(void*), VT_PTR}, // p pointer
{'s', sizeof(BSTR), VT_LPSTR}, // s string
{'t', sizeof(short), VT_I2}, // t short
{'u', sizeof(UINT), VT_UINT}, // u unsigned int
{'w', sizeof(BSTR), VT_LPWSTR}, // w wide string
}

请教返回值为布尔类型应该选哪个？[/b]
