这篇文章主要介绍了php批量去除bom头代码分享,本文直接给出实现代码,代码比较简单,容易看懂,需要的朋友可以参考下
;}else{$dirname = $basedir.http://www.jb51.net/.$file;checkdir($dirname);}} } closedir($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, $rest);return (发现bom并且已自动删除); } else {return (发现bom); } } else return (没有发现bom); } function rewrite ($filename, $data) { $filenum = fopen($filename, w); flock($filenum, lock_ex); fwrite($filenum, $data); fclose($filenum); } ?>
