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。
