php删除指定目录的方法

本文实例讲述了php删除指定目录的方法。分享给大家供大家参考。具体分析如下：

这段代码可实现递归删除子目录的功能

    <?php
    /**
     * Delete a file, or a folder and its contents 
     * (recursive algorithm)
     * @author Aidan Lister <aidan@php.net>
     * @version 1.0.3
     * @param string  $dirname Directory to delete
     * @return bool Returns TRUE on success, FALSE on failure
     */
    function rmdirr($dirname)
    {
     // Sanity check
     if (!file_exists($dirname)) {
      return false;
     }
     // Simple delete for a file
     if (is_file($dirname) || is_link($dirname)) {
      return unlink($dirname);
     }
     // Loop through the folder
     $dir = dir($dirname);
     while (false !== $entry = $dir->read()) {
      // Skip pointers
      if ($entry == '.' || $entry == '..') {
       continue;
      }
      // Recurse
      rmdirr($dirname . DIRECTORY_SEPARATOR . $entry);
     }
     // Clean up
     $dir->close();
     return rmdir($dirname);
    }
    ?>

希望本文所述对大家的php程序设计有所帮助。
