PHP simplest Delete directory and file implementation method _php

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:

The code is 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:

The code is 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.
