php 删除文件与目录代码是对文件与目录管理时会常用到了, 其实我们是删除文件后再删除目录的,因为php不能直接删除不是null的文件夹.

function RmDirFiles($indir)
{
$dh = dir($indir);
while($filename = $dh->read()) {
if($filename == "." || $filename == "..")
continue;
else if(is_file("$indir/$filename"))
@unlink("$indir/$filename");
else
$this->RmDirFiles("$indir/$filename");
}
$dh->close();
@rmdir($indir);
}
//获得某目录合符规则的文件
function GetMatchFiles($indir,$fileexp,&$filearr)
{
$dh = dir($indir);
while($filename = $dh->read())
{
$truefile = $indir.'/'.$filename;
if($filename == "." || $filename == ".."){
continue;
}
else if(is_dir($truefile)){
$this->GetMatchFiles($truefile,$fileexp,$filearr);
}
else if(preg_match("/.(".$fileexp.")/i",$filename)){
$filearr[] = $truefile;
}
}
$dh->close();
}
//删除文件
function DeleteFile($filename)
{
$filename = $this->baseDir.$this->activeDir."/$filename";
if(is_file($filename)){ @unlink($filename); $t="文件"; }
else{
$t = "目录";
if($this->allowDeleteDir==1) $this->RmDirFiles($filename);
}
ShowMsg("成功删除一个".$t."！","file_manage_main.php?activepath=".$this->activeDir);
return 0;
}
