PHP文件夾創建、刪除

1，寫入文件

<?
        header("Content-type: text/html;charset=gb2312");
        set_time_limit(0);
        $fileName = "log/log.txt";
        for($i=0;$i < 100;$i++ )
        {
             $data = "admin".$i."        ".date("Y-m-d H:i:s")."         恭喜添加成功!\n";
             if( writeLog( $fileName,$data ) )
             {
                 echo "good\n";
             }else{
                 echo "bad\n";
             }        
        }
        
        function writeLog($fileName,$data,$method="W")
        {
                $fp = fopen($fileName,$data,$method);
                flock($fp,LOCK_EX);    //如果文件不存在則創建文件
                $fileData = fwrite($fp,$data);
                if(!$fileData)
                {
                        return FALSE;
                }else{
                        return TRUE;
                }
        }
?>

2、創建文件目錄

<?
        header("Content-type: text/html;charset=gb2312");
        /*
         *@param string $path
         *@return Boolean
        */
        function makeDir($path)
        {    
                if( empty($path) )
                {
                    echo    "路徑不能為空";
                }
                $dirs = array();
                $path = preg_replace('/(\/){2,}|{\\\}{1,}/','/',$path);
                $dirs = explode("/",$path);
                $path ="";
                foreach($dirs as $folder)
                {
                        $path.=$folder."/";
                        if(!is_dir($path))
                        {
                                mkdir($path,0700) ;
                        }
                }
                if( is_dir($path) )
                {
                        return TRUE;
                }else{
                        return FALSE;
                }
        }
        $mk = makeDir( 'test/test/sda/ete/eterer/*\//ere/ew/');
        if( $mk )
        {
                echo    "創建成功！";
        }else{
                echo "創建失敗！";
        }
?>

3、刪除文件

<?
        header("Content-type: text/html;charset=gb2312");
        
        function rmFile($path,$fileName)
        {
                 $path = preg_replace('/(\/){2,}|{\\\}{1,}/','/',$path);
                 $path.= $fileName;
                if(is_file($path))
                {
                            unlink($path);
                }else{
                        echo $path."路徑不存在！";
                }
                
        }
        rmFile('test/test/sda/ete/eterer/ere/ew/','1.txt');
?>
