批量去除PHP文件中bom的PHP代码

需要去除BOM，就把附件里的tool.php文件放到目标目录，然后在浏览器访问tool.php即可！ 

复制代码代码如下:

<?php 
//此文件用于快速测试UTF8编码的文件是不是加了BOM，并可自动移除 
$basedir="."; //修改此行为需要检测的目录，点表示当前目录 
$auto=1; //是否自动移除发现的BOM信息。1为是，0为否。 
//以下不用改动 
if ($dh = opendir($basedir)) { 
while (($file = readdir($dh)) !== false) { 
if ($file!='.' && $file!='..' && !is_dir($basedir."/".$file)) 
echo "filename: $file ".checkBOM("$basedir/$file")." <br>"; 
} 
closedir($dh); 
} 
function checkBOM ($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, $rest); 
return ("<font color=red>BOM found, automatically removed.</font>"); 
} else { 
return ("<font color=red>BOM found.</font>"); 
} 
}else 
return ("BOM Not Found."); 
} 
function rewrite ($filename, $data) { 
$filenum=fopen($filename,"w"); 
flock($filenum,LOCK_EX); 
fwrite($filenum,$data); 
fclose($filenum); 
} 
?>
