PHP The simplest way to delete directories and files,

This article describes the simplest way to remove directories and files in PHP. Share to everyone for your reference.

The specific implementation code is as follows:
Copy the Code code as follows: <?php
Delete all empty directories under directory
Array_map (' RmDir ', glob (' * ', glob_onlydir));
Delete directory All files
Array_map (' unlink ', Array_filter (glob (' * '), ' is_file '));
?>
Principle Analysis: Array_map (' RmDir ', glob (' * ', glob_onlydir));

The simple deletion is the use of the Array_map function, which is to return the user-defined function of the array, the callback function accepts the number of arguments should be the same as the number of arrays passed to the Array_map () function, and Glob is to traverse the directory, and then return the array to rmdir for directory deletion And then:
Copy the Code code as follows: Array_map (' unlink ', Array_filter (glob (' * '), ' is_file '));

The principle is similar, that is, after traversing the directory, we can delete the files in the specified directory.

I hope this article is helpful to everyone's PHP programming.
