Just replace "eval" with "print" Smile

Code:

function check_serial_valid() {
$host = $_SERVER['HTTP_HOST'];

if (preg_match("/^(www.)(.*)/si", $host, $matches)) {
$wwwhost = $host;
$nonwwwhost = preg_replace("/^(www.)?/si", "", $wwwhost);
} else {
$nonwwwhost = $host;
$wwwhost = "www." . $host;
}

if ($_SERVER['HTTP_HOST'] == "localhost" || $_SERVER['HTTP_HOST'] == "localhost:" . $_SERVER['SERVER_PORT']) {
return true;
} else {
if ($serial = wls_get_serial()) {

if (function_exists("curl_exec")) {

$serial = get_option('wls_license');
$prod_name = LICENSEMANAGER_NAME;
//$domain = $_SERVER['HTTP_HOST'];
$domain = $_SERVER['SERVER_NAME'];
if (substr($domain, 0, 4) == "www.") { $domain = substr($domain, 4);}
$userip = isset($_SERVER['SERVER_ADDR']) ? $_SERVER['SERVER_ADDR'] : $_SERVER['LOCAL_ADDR'];
$ip = gethostbyname($domain);

$validdir = dirname(__FILE__);
$validdomain = str_replace("www.", "", $domain);

$key_info['key'] = $serial;
$key_info['domain'] = $validdomain;
$key_info['validip'] = $userip;
$key_info['validdir'] = $validdir;
$key_info['product'] = $prod_name;

$serverurl = "http://shop.wpbuz.com/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $serverurl."wp-content/plugins/wp-licensing/auth/verify.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $key_info);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

$results = array();
$result = json_decode($result, true);

if($result['valid'] == "true"){
return true;
} else {
if ($serial == strtoupper(md5($_SERVER['HTTP_HOST'] . "wpDEVpro" . "myb3mb3sc3nt1ks3k4l1w35w35"))) {
return true;
} elseif (strtoupper(md5($wwwhost . "wpDEVpro" . "myb3mb3sc3nt1ks3k4l1w35w35")) == $serial ||

$serverurl = "http://wpbuz.com/ev/check.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $serverurl);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 43200);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $key_info);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

$results = array();
$result = json_decode($result, true);

if($result['valid'] == "true"){
return true;
}
}
}

} else {

if ($serial == strtoupper(md5($_SERVER['HTTP_HOST'] . "wpDEVpro" . "myb3mb3sc3nt1ks3k4l1w35w35"))) {
return true;
} elseif (strtoupper(md5($wwwhost . "wpDEVpro" . "myb3mb3sc3nt1ks3k4l1w35w35")) == $serial ||

return false;

Nice work although I would opt for highlight_string over print/echo anyday, for those unaware of this nifty function refer to php.net to see the benefits/reasons why. Smile
