php 文件夾刪除、php清除緩存程序
Jun 13, 2016 pm 12:22 PM
復(fù)制代碼 代碼如下:
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);
}
/*
* 方便統(tǒng)計(jì)目錄數(shù)
*/
$filesize['file'] = 0;
if(@rmdir($fpath) === true) {
echo "{$filepath}................刪除成功
\n";
} else {
echo "{$filepath}................刪除失敗
\n";
}
} else {
if(is_file($fpath)) {
$filesize[] = $fsize = filesize($fpath);
if(@unlink($fpath) === true) {
echo "{$filepath}...{$fsize}K................刪除成功
\n";
} else {
echo "{$filepath}...{$fsize}K................刪除失敗
\n";
}
}
}
return $filesize;
}
/*
* function getArrSum(array &$arr) 數(shù)組求和
* array &$arr 被處理數(shù)組
*/
function getArrSum(&$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('為您節(jié)?。?.3fM 空間', $size/(1024*1024));
?>
只要在D盤(pán)下建一個(gè) test 文件夾，然后再里面隨便拷入一點(diǎn)東西就可以測(cè)試了
