PHP中GD库的官方站文档中有显示ImageGifAnimBegin这个函数,为什么我用在PHP中会提示undefined function?
http://www.libgd.org/ImageCreation#void_gdImageGifAnimBegin.28gdImagePtr_im.2C_FILE_.2Aout.2C_int_GlobalCM.2C_int_Loops.29
以上链接是GD库的官方ImageCreation的说明文档,其中有对gdImageGifAnimBegin函数进说说明,还有例子,可为什么我用在PHP中时会提示undefined function呢

------解决方案--------------------
未安装gd2

将 php\extensions\php_gd2.dll copy 到windows目录，
修改php.ini 中 ";extension=php_gd2.dll"前面的 ";"去掉。

------解决方案--------------------
人家并没有说PHP里有这东西啊
