 $s='';
 echo $s;
 //生成 加密后的PHP文件
 !is_dir('create/') && mkdir('create/');
 $fpp1 = fopen('create/'.$filename,'w');
 fwrite($fpp1,$s) or die('写文件错误');
 echo '加密成功！';

Method two:

');  
         $contents = substr($contents, $headerPos + 5, $footerPos - $headerPos);  
         $encode = base64_encode(gzdeflate($contents)); // 开始编码  
         $encode = '";   
 
         return file_put_contents($filename, $encode);  
     }
