[英]how to delete a file in php from a directory
I am logged into Windows with an administrator account. 我已使用管理员帐户登录Windows。
I used the unlink($filename)
function to delete a file using php but it gives me the following error: 我使用
unlink($filename)
函数使用php删除文件,但它给了我以下错误:
Warning: unlink(C:/wamp/www/jedda/wp-content/uploads/) [function.unlink]: Permission denied in C:\\wamp\\www\\Jedda\\wp-content\\plugins\\course management\\course_file.php on line 242
警告:取消链接(C:/ wamp / www / jedda / wp-content / uploads /)[function.unlink]:权限在C:\\ wamp \\ www \\ Jedda \\ wp-content \\ plugins \\ course management \\ course_file.php中被拒绝在第242行
So how can I delete the file using php? 那么如何使用php删除文件?
您没有删除此文件的权限,无法删除此文件。您可以尝试修改文件权限。
If you want to delete a directory you have to use rmdir command. 如果要删除目录,则必须使用rmdir命令。 And the specific directory has to be empty.
并且特定目录必须为空。 You can use a function like scandir first to list the files and directories of the specific directory and delete the files with unlink .
您可以先使用诸如scandir之类的功能列出特定目录的文件和目录,然后使用unlink删除文件。
Use this PHP script:- 使用此PHP脚本:-
<?php
function rmdirr($dirname)
{
// Sanity check
if (!file_exists($dirname)) {
return false;
}
// Simple delete for a file
if (is_file($dirname)) {
return unlink($dirname);
}
// Loop through the folder
$dir = dir($dirname);
while (false !== $entry = $dir->read()) {
// Skip pointers
if ($entry == '.' || $entry == '..') {
continue;
}
// Recurse
rmdirr("$dirname/$entry");
}
// Clean up
$dir->close();
return rmdir($dirname);
}
?>
This script is to delete a file or a folder.... both 该脚本将删除文件或文件夹。
