复制代码 代码如下:
STDMETHODIMP CMyClass::add(LONG a, LONG b, LONG* c)
{
*c = a + b;
return S_OK;
}
8、编译后,在生成目录找到ComTest.dll,注册到系统
复制代码 代码如下:
regsvr32 ComTest.dll
二、PHP调用COM组件
复制代码 代码如下:
$com = new COM("ComTest.MyClass") or die("无法调用ComTest");
echo $com->add(1, 2);
正常情况下,到这里就完成了。
但默认情况下,PHP调用COM组件的功能是没有打开的。PHP执行以上代码就会报 Fatal error: Class 'COM' not found 错误。修改PHP配置,如下:
复制代码 代码如下:
extension=php_com_dotnet.dll
结束语
这个功能是PHP调用COM组件的功能,虽然很方便调用,开发也比较简单,但也因为使用COM组件技术,限定了只有Windows的机子才能使用。
