php 文件夹删除、php清除缓存程序_PHP教程

复制代码 代码如下:

header('content-type:text/html;charset=utf-8');
function delFile($fpath) {
$filesize = array();
$filepath = iconv('gb2312', 'utf-8', $fpath);
if (is_dir($fpath)) {
if ($dh = opendir($fpath)) {
while (($file = readdir($dh)) !== false) {
if($file != '.' && $file != '..') {
$filesize[] = delFile($fpath.'/'.$file);
}
}
closedir($dh);
}
/*
* 方便统计目录数
*/
$filesize['file'] = 0;
if(@rmdir($fpath) === true) {
echo "{$filepath}................删除成功
\n";
} else {
echo "{$filepath}................删除失败
\n";
}
} else {
if(is_file($fpath)) {
$filesize[] = $fsize = filesize($fpath);
if(@unlink($fpath) === true) {
echo "{$filepath}...{$fsize}K................删除成功
\n";
} else {
echo "{$filepath}...{$fsize}K................删除失败
\n";
}
}
}
return $filesize;
}
/*
* function getArrSum(array &$arr) 数组求和
* array &$arr 被处理数组
*/
function getArrSum(&$arr) {
if(is_array($arr)) {
foreach ($arr as &$value) {
$value = getArrSum($value);
}
return array_sum($arr);
} else {
return $arr;
}
}
$fpath = 'D:/test';
$filesize = delFile($fpath);
$size = getArrSum($filesize);
printf('为您节省：%.3fM 空间', $size/(1024*1024));
?>

只要在D盘下建一个 test 文件夹，然后再里面随便拷入一点东西就可以测试了
