SWF PHP offers the ability to create Shockwave Flash files via Paul Haeberli's libswf module. You can download libswf at &url.swf;. 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. 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: ]]> SWF support was added in PHP 4 RC2. The libswf does not have support for Windows. The development of that library has been stopped, and the source is not available to port it to another systems. swf_openfile Open a new Shockwave Flash file void swf_openfile string filename float width float height float framerate float r float g float b The swf_openfile function opens a new file named filename with a width of width and a height of height a frame rate of framerate and background with a red color of r a green color of g and a blue color of b. The swf_openfile must be the first function you call, otherwise your script will cause a segfault. If you want to send your output to the screen make the filename: "php://stdout" (support for this is in 4.0.1 and up). swf_closefile Close the current Shockwave Flash file void swf_closefile int return_file Close a file that was opened by the swf_openfile function. If the return_file parameter is set then the contents of the SWF file are returned from the function. ]]> swf_labelframe Label the current frame void swf_labelframe string name Label the current frame with the name given by the name parameter. swf_showframe Display the current frame void swf_showframe The swf_showframe function will output the current frame. swf_setframe Switch to a specified frame void swf_setframe int framenumber The swf_setframe changes the active frame to the frame specified by framenumber. swf_getframe Get the frame number of the current frame int swf_getframe The swf_getframe function gets the number of the current frame. swf_mulcolor Sets the global multiply color to the rgba value specified void swf_mulcolor float r float g float b float a The swf_mulcolor function sets the global multiply color to the rgba color specified. This color is then used (implicitly) by the swf_placeobject, swf_modifyobject and the swf_addbuttonrecord functions.

The rgba values can be either positive or negative. swf_addcolor Set the global add color to the rgba value specified void swf_addcolor float r float g float b float a The swf_addcolor function sets the global add color to the rgba color specified.

Full RGBA colors are supported. swf_modifyobject Modify an object void swf_modifyobject int depth int how Updates the position and/or color of the object at the specified depth, depth. The parameter how determines what is updated. how can either be the constant MOD_MATRIX or MOD_COLOR or it can be a combination of both (MOD_MATRIX|MOD_COLOR). MOD_COLOR uses the current mulcolor (specified by the function swf_mulcolor) and addcolor (specified by the function swf_addcolor) to color the object. MOD_MATRIX uses the current matrix to position the object. swf_removeobject Remove an object void swf_removeobject int depth Removes the object at the depth specified by depth. swf_nextid Returns the next free object id int swf_nextid The swf_nextid function returns the next available object id. swf_startdoaction Start a description of an action list for the current frame void swf_startdoaction The swf_startdoaction function starts the description of an action list for the current frame.

If a perspective transformation is desired, the swf_perspective function can be used. swf_perspective Define a perspective projection transformation void swf_perspective float fovy float aspect float near float far The swf_perspective function defines a perspective projection transformation. The fovy parameter is field-of-view angle in the y direction. The aspect parameter should be set to the aspect ratio of the viewport that is being drawn onto. The near parameter is the near clipping plane and the far parameter is the far clipping plane.

Some are not to pretty. swf_polarview Define the viewer's position with polar coordinates void swf_polarview float dist float azimuth float incidence float twist The swf_polarview function defines the viewer's position in polar coordinates. The dist parameter gives the distance between the viewpoint to the world space origin.

The incidence parameter defines the angle of incidence in the y,z plane, measured in distance from the z axis. The incidence angle is defined as the angle of the viewport relative to the z axis. Finally the twist specifies the amount that the viewpoint is to be rotated about the line of sight using the right hand rule. swf_lookat Define a viewing transformation void swf_lookat float view_x float view_y float view_z float reference_x float reference_y float reference_z float twist The swf_lookat function defines a viewing transformation by giving the viewing position (the parameters view_x, view_y, and view_z) and the coordinates of a reference point in the scene, the reference point is defined by the reference_x, reference_y , and reference_z parameters.
