方法1

publicfunctionverify(){ob_clean();//清除BOM信息$Verify=new\Think\Verify();$Verify->entry();}

方法2

<?phpif(isset($_GET['dir'])){//设置文件目录$basedir=$_GET['dir'];}else{$basedir='.';}$auto=1;checkdir($basedir);functioncheckdir($basedir){if($dh=opendir($basedir)){while(($file=readdir($dh))!==false){if($file!='.'&&$file!='..'){if(!is_dir($basedir."/".$file)){echo"filename:$basedir/$file".checkBOM("$basedir/$file")."<br>";}else{$dirname=$basedir."/".$file;checkdir($dirname);}}}closedir($dh);}}functioncheckBOM($filename){global$auto;$contents=file_get_contents($filename);$charset[1]=substr($contents,0,1);$charset[2]=substr($contents,1,1);$charset[3]=substr($contents,2,1);if(ord($charset[1])==239&&ord($charset[2])==187&&ord($charset[3])==191){if($auto==1){$rest=substr($contents,3);rewrite($filename,$rest);return("<fontcolor=red>BOMfound,automaticallyremoved.</font>");}else{return("<fontcolor=red>BOMfound.</font>");}}elsereturn("BOMNotFound.");}functionrewrite($filename,$data){$filenum=fopen($filename,"w");flock($filenum,LOCK_EX);fwrite($filenum,$data);fclose($filenum);}?>

根目录保存文件执行，即可清除BOM
