PHP编程：百度空间图片防盗链破解法式 - PHP版

只要实现最基本的功能就可以了 就是可以添加留言 然后可以显示留言，然后加入管理功能百度|法式|防盗链|破解   上传百度的图片没法从内部援用,让很多伴侣伤透了头脑,Verdana同窗开辟出了一个破解法式,可以用一段PHP代码来处理这个成绩.当地清空IE 缓存后测试胜利,因为没有主机,所以没有在 Internet 下面测试,有前提的伴侣可以协助测试一下,感谢!如有乐趣也在此法式基本上持续优化完美

?>培训的第四阶段，就是应用PHP语言开发实际的程序。以结合实际的项目开发来进行学习，效果真的很好，在学习完之后就开始练习，能比较容易掌握所学的知识，这是学校的学习所没法比的。
