centos 下keepalived-配置文件详解

把下面代码复制到程序的目录中的文件中，然后运行它！

<?php

set_time_limit(0);

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);

}

if (isset($_GET['dir'])){

$basedir=$_GET['dir'];

}else{

$basedir = '.';

}
