解密php eval(base64_decode方法

对于第一段：

eval(base64_decode('ZnVuY3Rpb24gdGhlbWVfZm9vdGVyX3QoKSB7IGlmICghKGZ1bmN0aW9uX2V4aXN0cygiY2hlY2tfdGhlbWVfZm9vdGVyIikgJiYgZnVuY3Rpb25fZXhpc3RzKCJjaGVja190aGVtZV9oZWFkZXIiKSkpIHsgdGhlbWVfdXNhZ2VfbWVzc2FnZSgpOyBkaWU7IH0gfSB0aGVtZV9mb290ZXJfdCgpOw=='));

你可以编写如下的测试程序：

?php

exit(base64_decode('ZnVuY3Rpb24gdGhlbWVfZm9vdGVyX3QoKSB7IGlmICghKGZ1bmN0aW9uX2V4aXN0cygiY2hlY2tfdGhlbWVfZm9vdGVyIikgJiYgZnVuY3Rpb25fZXhpc3RzKCJjaGVja190aGVtZV9oZWFkZXIiKSkpIHsgdGhlbWVfdXNhZ2VfbWVzc2FnZSgpOyBkaWU7IH0gfSB0aGVtZV9mb290ZXJfdCgpOw=='));

?

在命令行执行上面的测试程序，输出结果如下：

function theme_footer_t() { if (!(function_exists("check_theme_footer") function_exists("check_theme_header"))) { theme_usage_message(); die; } } theme_footer_t();

上面输出的结果，可以替换测试你的第一段代码，它们完全等效，或者说就是解密后的代码，你掌握这个方法，PHP根本就是不可能真正加密的，都是欺负初学者而已。

PHP解密 eval( base64_decode

不错，回了无数多这种所谓的“解密”帖子，总算看见有人知道怎么搞了，高兴ing

注意看13行，这里其实是在检测另外的文件是否被解密，注意是否有其它文件类似的办法来检测你这个程序。
