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。
