HTML中head里的内容经浏览器解析后全到body里了
修改完代码后,用chrome审查元素,head里的内容都到body中去了

<?php $basedir = str_replace('/clearBOM.php','',str_replace('\','/',dirname(__FILE__))); $auto = 1; checkdir($basedir); function checkdir($basedir){ if ($dh = opendir($basedir)) { while (($file = readdir($dh)) !== false) { if ($file != '.' && $file != '..'){ if (!is_dir($basedir.'/'.$file)) { $filename = $basedir.'/'.$file; echo 'filename:'.$basedir.'/'.$file.checkBOM($filename).'<br>'; } else { $dirname = $basedir.'/'.$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, $rest); return '<font color=red>BOM found,automatically removed.</font>'; } else { return '<font color=red>BOM found.</font>'; } } else { return 'BOM Not Found.'; } } function rewrite ($filename, $data) { $filenum = fopen($filename, 'w'); flock($filenum, LOCK_EX); fwrite($filenum, $data); fclose($filenum); } ?>
使用的方法是将该代码放入文件后放在网站的根目录,或者你想去哪个目录的BOM就放在哪个目录,然后直接用URL访问这个PHP文件就可以了!
