may help you . As I mentioned, you should not be using the ext/mysql extension for new code. Until it is purged from all those ancient PHP tutorials on the internet, we wont see the end of people going "Why doesn't my code work any more", because using it throws E_DEPRECATED in PHP 5.5, and it will be removed completely in later versions.
This uses the mysqli extension, with prepared queries (you can also use PDO).
code :
$db = new mysqli($dbip, $dbuser, $dbpass, $dbname);

if ($query = $db->prepare("INSERT INTO table_name (x, y) values (?, ?)")) {
    $query->bind_param("ss", $_POST["x"], $_POST["y"]); // s = string, i = int
} else {
    echo json_encode(array("error" => "malformed query"));
    return false;
    // in PHP, false or null both signify an error in a non-boolean context
echo json_encode(array("success" => "query attempted"));
return true;
json_encode(array("query attempted")); // ["success"]
json_encode(array("success" => "more info")); // {"success":"more info"}
json_encode(utf8_encode(array("success" => "more info"))); // null
. $_POST[NewLocation] .

To fix this issue (More a comment that an answer, but I need more space).
The braces in the expression, that Sverri mentions do nothing and are just confusing. Just leave them out.
code :
if (!$fileinfo->isFile()) continue;{
$files[] .= $pathname;
if (!$fileinfo->isFile()) continue;
$files[] = $pathname;
