Using a wildcard in php unlink

问题 I am currently making a php script to graph a bunch of data from a DB, arrange it into text files and then run a GNUPlot script to generate graphs. I have all of this working , now all I need to do is delete the text files I don't need anymore. What I have been trying was gotten from another thread on a different forum: foreach( glob('US_A.2.6.*') as $file ) { unlink($file); } The problem, however, is that it doesn't work. The files have complex end names: US_A.2.6.1.1a.txt US_A.2.6.1.2a.txt

PWN学习笔记

久违的更一篇博客总结一点比较基础的PWN题的套路(用户态linux pwn),过一段时间 可能 会更windows pwn和kernel pwn,这次先总结套路,过一段时间可能会加上具体的例子解析。 ptmalloc利用:分两部分来总结,第一步利用堆漏洞利用,第二部分getshell 对漏洞利用:   fastbins attack,fast bins特性:是一个单项链表,只有fd指针,最后一个chunk的fd指向null。并且在free掉之后,并不会修改下一块相邻的chunk的pre_size位,即不会发生free时合并。但当申请一块small bins大小或large bins大小,在unsorted bins查找之前,会遍历fast bins进行合并,并将合并后的chunk放入unsortedbins   unlink :smallbins 过检查fd->bk=victim bk->fd=victim large bins增加对fd_nextsize和bk_nextsize的检查。unsorted bins 则不存在检查 绕过方式有两种:一 如果存在一个全局变量,是题目进行存储malloc指针的数组,这时如果将fd改为 address-0x18 bk改为 address-0x10即可绕过检查。下一步触发unlink,将全局变量改为address -0x18

Why is unlink successful on an open file?

不羁的心 提交于 2020-02-15 10:12:37
问题 Why open file is deleted? On Windows Xamp, I get message "still working", but on other PHP serwer file is deleted, even if it is open and I get message "file deleted". I can delete file from FTP too, even if first script is still working :( <?php $handle = fopen("resource.txt", "x"); sleep(10); ?> <?php if (file_exists("resource.txt") && @unlink("resource.txt") === false) { echo "still worning"; exit; } else echo "file deleted"; ?> 回答1: UNIX systems typically let you do this, yes.

PHP封装清除目录下的所有文件函数

白昼怎懂夜的黑 提交于 2020-02-08 09:44:25
由于经常会遇到定期清除日志或者定期清除过期文件的需求,网上查阅了部分资料,借鉴了一位大佬的思想方法,有了如下感悟 1.PHP清除目录下的所有文件(测试使用版) function deldir ( $path ) { echo $path ; echo PHP_EOL ; //如果是目录则继续 if ( is_dir ( $path ) ) { //扫描一个文件夹内的所有文件夹和文件并返回数组 $p = scandir ( $path ) ; foreach ( $p as $val ) { //排除目录中的.和.. if ( $val != "." && $val != ".." ) { //如果是目录则递归子目录,继续操作 //is_dir() 函数检查指定的文件是否是一个目录 if ( is_dir ( $path . '/' . $val ) ) { //子目录中操作删除文件夹和文件 $this - > deldir ( $path . '/' . $val . '/' ) ; //目录清空后删除空文件夹 @ rmdir ( $path . '/' . $val ) ; print_r ( '删除空目录' . $path . '/' . $val ) ; echo PHP_EOL ; } else { //如果是文件直接删除 unlink ( $path . $val ) ;

PHP recursive delete function

问题 I wrote recursive PHP function for folder deletion. I wonder, how do I modify this function to delete all files and folders in webhosting, excluding given array of files and folder names (for ex. cgi-bin, .htaccess)? BTW to use this function to totally remove a directory calling like this recursive_remove_directory('path/to/directory/to/delete'); to use this function to empty a directory calling like this: recursive_remove_directory('path/to/full_directory',TRUE); Now the function is function

问题 i've been trying to figure out why my Php code is giving me a annoying error. I've tried countless functions from previous post but the error its been giving is "Permission Denied".
