RegEx:从regexp获得错误'empty(sub)expression'

I have a column phone which contains a value like this:

["1740235959","9106597107","9369326058","9168187280","9393503006","9169124377","9378152001","9168176167","9385156441","9166118105","9166110676"]

which are phone found.

sent and receive result to client by this:

if ($tag=='getFriends'){
    $tempArray = array();
    foreach ($_POST["phoneNumbers"] as $phoneNumber) {
        $friends = $db->getFriends($phoneNumber);
        array_push($tempArray,($friends));
    }
    echo json_encode($tempArray);
}

And Here is my getFriends() method:

public function getFriends($phoneNumber){
    $newNumber = substr($phoneNumber, -10);
    $result = mysql_query("SELECT * FROM users WHERE phone REGEXP '$newNumber' LIMIT 1") or die(mysql_error());
    $rows = mysql_num_rows($result);
    if ($rows>0) {
    $result = mysql_fetch_array($result);
    $response["error"] = FALSE;
    $response["getFriends"]["real_name"] = $result["real_name"];
    $response["getFriends"]["name"] = $result["name"];
    $response["getFriends"]["email"] = $result["email"];
    $response["getFriends"]["is_online"] = $result["is_online"];
    $response["getFriends"]["in_game"] = $result["in_game"];
    $response["getFriends"]["status"] = $result["status"];
    $response["getFriends"]["user_unique_id"] = $result["user_unique_id"];
    }else {
        $response["error"] = TRUE;
    }
    return $response;

}

And the error message I get:

Got error 'empty (sub)expression' from regexp

What am I doing wrong?
