用php把utf8的中的BOM去掉
今天看到一段不错的php程序,可以自动把你所有的文件的BOM去掉,而这全部过程只需要上传并运行一下,非常不错,保留下来方便下次使用。
代码
Write UTF-8 BOM=0
Write UTF-8 BOM NF=0
这段php程序如下,保存成php文件放在根目录中执行一次就行了,会自动去除文件头中的BOM。
<?php
//remove the utf-8 boms
//by magicbug at gmail dot com
if (isset($_GET['dir'])){ //config the basedir
$basedir=$_GET['dir'];
}else{
$basedir = '.';
}
$auto = 1;
checkdir($basedir);
function checkdir($basedir){
if ($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);
}
}
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);
}
?>
