Cleverly use PHP recursive functions to traverse and delete entire directories and files

How to use PHP recursive functions to traverse and delete entire directories and files. Several examples of PHP recursive functions operating directory files. Use PHP recursive methods to delete directories and files.

php method to traverse and delete the entire directory and files (php recursive function)

Example 1, use RecursiveDirectoryIterator and RecursiveIteratorIterator to delete directories, subdirectories and files. The subdirectories will be deleted with the parent directory first.

Copy code Code example: isDir()) { rmdir($f->getPathname()); } else { unlink($f->getPathname()); } } rmdir($dir); } cleanup_directory('c:\wamp\junk'); ?>

2. PHP implements traversing the directory and deleting the specified content in the specified file (example of PHP recursive function)

php implements traversing directories and deleting specified content in specified files

php recursive function traverses the directory, finds all files with the specified file name, and deletes the specified string within them.

Example:

Copy code Code example: Enter relevant information"; } ?>

Enter the target folder: Enter the target file name: Enter the string to be deleted:

As shown in the picture:

You can see that I wrote two functions. The function traverse writes the specified file paths found in a temporary file, and the function del deletes the specified strings in these files. In fact, I also think it is useless, just delete it directly during traversal, and there is no need to generate any temporary files at all.

In fact, the traversal was written in C language at first. Because C language is not easy to operate files, I used PHP to write the deleted part. So I only wrote a del function at the beginning, and later I simply wrote the traversal file in PHP as well ( It seems much simpler than C), so I wrote another function traverse. You can just look at the traversal part. You can also compare it with the traversal code I wrote in C before (I sent the source code) to see what the difference is. However, this version does not support wildcards, so the file name must be specified. Its function (also the reason why I wrote this) is that it can delete the one-sentence Trojans we have hung on the server in batches.
