link–用于创建一个现有文件的链接；实际上是新建一个目录项，指向当前文件的i节点； unlink–用于删除一个现有文件的连接；实际上是对引用i节点的目录项进行删除，并且对链接计数-1；系统会检查文件被进程的引用计数（如被进程打开，引用计数会+1，关闭则-1），如果该引用计数为0，并且链接计数为0，则会删除该文件； 比如shell中的rm命令，就是使用unlink函数实现的； mkdir–用于创建一个新的空目录，目录中只包含. 和 ..； rmdir–用于删除一个空目录，也就是只能删除包含.和..的目录； remove–对于文件，remove的功能与unlink相同；对于目录，remove的功能与rmdir相同； 来源： https://www.cnblogs.com/wanpengcoder/p/11762742.html

So this one is pretty straight forward I want to delete a file on the server using PHP, I have: $myfile = 'theone.png'; unlink($myfile); This code deletes the file, howevere if the path to file is /images/theone.png, it doesn't work, I have tried images\theone.png with no luck. If I try and connect with FTP I get the error message to say that cURL does not support the unlink function... Any help would be great. Thanks Guys! What about: $root = realpath($_SERVER['DOCUMENT_ROOT']); $myfile = '$root/images/theone.png'; unlink($myfile); Although to my knowledge, your attempted method should work,

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 recursive_remove_directory($directory, $empty=FALSE) { // if the path has a slash at the end we remove

防御脚本 github上的awd通防脚本三个。一个记录敏感请求，一个记录所有的东西。一个是waf，针对sql注入的。 wafjk.php wafjk.php是用来记录敏感操作的，可以自行修改pattern，增加更多的敏感函数，只要匹配到，就会记录下来敏感操作。 首先我在index.php包含了include "wafjk.php"; <?php error_reporting(0); define('LOG_FILENAME', './log.txt'); function waf() { if (!function_exists('getallheaders')) { function getallheaders() { foreach ($_SERVER as $name => $value) { if (substr($name, 0, 5) == 'HTTP_') $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5))))) ] = $value; } return $headers; } } $get = $_GET; $post = $_POST; $cookie = $_COOKIE; $header = getallheaders();

I'm using UNLINK with PHP and AJAX . I know that in this way is very dangerous, because everyone can delete any files. But I need to use AJAX because I can't reload the page when I delete the files. So how should I do to allow to delete the file only for the user who owns it? Please let me know other things too if you think I'm doing here something wrong or something else what you have in mind and you think that it will be useful : ) My PHP code: <?php $photo_id = $_GET['photo_id']; $thumbnail_id = $_GET['thumbnail_id']; function deletePhotos($id){ return unlink($id); } if(isset($photo_id)){

I would like to delete a file that is found in my localhost. localhost/project/folder/file_to_delete I'm using codeigniter for this. I would like to use the unlink() function in php but I really can't understand how to use it. you can use the "file helper" in codeigniter. http://codeigniter.com/user_guide/helpers/file_helper.html and like this : $this->load->helper("file"); delete_files($path); Late Edit: delete_files method uses a path to wipe out all of its contents via unlink() and same you can do within CI. Like this: unlink($path); a valid path. http://php.net/manual/en/function.unlink
