今天发现这个方式也是间或,在伏笔主机购买了独立ip空间后,装置指定的网站程序,装置完成后登陆后台时,验证码不显示,空间初始化了几次重新装置后,才初步判定是网站程序文件中有bom体式文件在,常规的是utf-8,他这个是utf-8+bom,所以涌现问题了。只是,这会儿你又不知道确却的文件是哪一个?怎么办勒?
接下来用这个方式,一定管用!

首先,你本土新建一个文件,这里定名为:RemoveBom.php
接着,把下面这段代码复制粘贴进去,上面定名的文件里面,然后保留一下,上传到网站根目次下面,接着直接运行该文件即可!
RemoveBom.php代码如下:

       $rest = substr($contents, 3); 

       rewrite ($filename, $rest); 

       return ("<font color=red>BOM found, automatically removed._<a

      } else

       return ("<font color=red>BOM found.</font>"); 

      

    

    else return ("BOM Not Found."); 

    

    function rewrite ($filename, $data) { 

    $filenum = fopen($filename, "w"); 

    flock($filenum, LOCK_EX); 

    fwrite($filenum, $data); 

    fclose($filenum);
