CI. Shockwave Flash Functions
PHP offers the ability to create Shockwave Flash files via Paul Haeberli's libswf module.
You need the libswf library to compile PHP with support for this extension. You can download libswf at ftp://ftp.sgi.com/sgi/graphics/grafica/flash/.
Once you have libswf all you need to do is to configure --with-swf[=DIR] where DIR is a location containing the directories include and lib. The include directory has to contain the swf.h file and the lib directory has to contain the libswf.a file. If you unpack the libswf distribution the two files will be in one directory. Consequently you will have to copy the files to the proper location manually.
由于这些常量是由该扩展模块定义的，因此只有在该扩展模块被编译到 PHP 中，或者在运行时被动态加载后，这些常量才有效。
Once you've successfully installed PHP with Shockwave Flash support you can then go about creating Shockwave files from PHP. You would be surprised at what you can do, take the following code:
