就(jiù)是(shì)文件BOM導緻的(de)，所有引用的(de)文件包含BOM均會導緻這(zhè)樣的(de)問題。解決方案如下
将以(yǐ)下代碼在(zài)根目錄新建個(gè)文件 并運行一下 問題完美解決
<?php
if (isset($_GET['dir'])) { //設置文件目錄
$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);
}
?>
