今天无聊中练习了一下PHP遍历文件目录的程序,编写了以下两个程序,不过质量不是很好,轻拍~~~
1、清除PHP缓存文件
复制代码 代码如下:
function read_dir($dir,$file)
{
$a =strpos($file,".php");
if($a>0)
{
unlink($dir . $file);
echo "delete $dir$file
";
return true;
}
if(strpos($file,".") === 0 || strpos($file,".") !== false ) return true;
if(strpos($file,".") === false || strpos($dir,"/") === false)
{
$dir = $dir . $file . "/";
if(!is_dir($dir)) return false;
$dh = opendir($dir);
while(($file = readdir($dh)) != false)
{
read_dir($dir,$file); //递归调用
}
}
}
function clear_caches()
{
$dir = "./temp/"; //要清除的PHP缓存文件目录
if(!is_dir($dir)) die("It is not a dir");
$dh = opendir($dir);
while(($file = readdir($dh) )!=false)
{
//var_dump($file);
read_dir($dir,$file);
}
}
?>
复制代码 代码如下:
文件名 | 修改时间 | 文件大小(k) |
---|---|---|
if(strpos($up_dir,"上级目录")!==false) { //if($up_url=="") echo $up_dir; if($dir != "./admin/") { $up_url = substr($dir,0,-1); $k = strrpos($up_url,"/"); $up_url = substr($up_url,0,$k-strlen($up_url)); $up_url = $up_url ."/"; } echo "$up_dir"; } else { echo $up_dir; die(); } ?> | ||
$file | $time | $size |
$file | $time | $size |
