PHP
函数
PHP
通过很小的函数调用集提供了
COM
接口，但其中大部分函数是需要
COM
详细知
识的底层函数，这些超出了本章的讨论范围。一个
COM
类的对象代表一个
COM
服务器
的连接 ：
$word = new COM("word.application") or die("Unable to start Word app");
对于大部分
OLE
自动化操作，最难的是将
Visual Basic
方法调用转换成等价的
PHP
语句。
例如，下面所示的是要将文本插入
Word
文件的
VBScript
：
Selection.TypeText Text := "
这是一个测试
"
同样的，用
PHP
编写是
：
$word->Selection->typetext("
这是一个测试
");
API
规范
要为像
Word
这样的产品确定对象层级和参数，可以访问
Microsoft
开发者网站并且搜索
你感兴趣的特定
Word
对象。另外一个选择是，用微软的在线
VB
脚本帮助和
Word
宏语
言。将它们结合使用可让你明白参数的顺序，以及给定任务所需的值。
