PHP解析错误：语法错误，意外T_VARIABLE [关闭]

I get this error: PHP Parse error: syntax error, unexpected T_VARIABLE on line 47

The 47th line is:

$queryb = "UPDATE `situation` SET `status`='" . $stats . "', `time`='" . $time . "', `name`='" . $name . "', `notes`='" . $notes . "'";

I just don't get it. Maybe script error or syntax error?

<?php
    function lanjut($c) {
    $submitdata = "success";
    if ($c = "message") {
        $time = $_REQUEST['time'];
        $name = $_REQUEST['name'];
        $body = $_REQUEST['body'];
        $con = mysqli_connect("this,is,already,true");
        $querya = "INSERT INTO `message` (`name`, `time`, `body`) VALUES ('" . $name . "', '" . $time . "', '" . $body . "')";
        mysqli_query($con,$query);
        mysqli_close($con);
    } elseif ($c = "setting") {
        $time = $_REQUEST['time'];
        $name = $_REQUEST['name'];
        $notes = $_REQUEST['notes'];
        $con = mysqli_connect("this,is,already,true");
        $stats = $_REQUEST['status']
        $queryb = "UPDATE `situation` SET `status`='" . $stats . "', `time`='" . $time . "', `name`='" . $name . "', `notes`='" . $notes . "'";
        mysqli_query($con,$query);
        mysqli_close($con);
    };
};
?>

Code without any syntax error will be

<?php
function lanjut($c)
{
    $submitdata = "success";
    if($c = "message") {
        $time = $_REQUEST['time'];
        $name = $_REQUEST['name'];
        $body = $_REQUEST['body'];
        $con = mysqli_connect("this,is,already,true");
        $querya = "INSERT INTO `message` (`name`, `time`, `body`) VALUES ('" . $name . "', '" . $time . "', '" . $body . "')";
        mysqli_query($con, $querya);
        mysqli_close($con);
    } elseif($c = "setting") {
        $time = $_REQUEST['time'];
        $name = $_REQUEST['name'];
        $notes = $_REQUEST['notes'];
        $con = mysqli_connect("this,is,already,true");
        $stats = $_REQUEST['status'];
        $queryb = "UPDATE `situation` SET `status`='" . $stats . "', `time`='" . $time . "', `name`='" . $name . "', `notes`='" . $notes . "'";
        mysqli_query($con, $queryb);
        mysqli_close($con);
    }
}
?>

A better way is to user prepared statements like

$querya = $con->prepare("INSERT INTO `message` (`name`, `time`, `body`) VALUES (? , ?, ?");
$querya->bind_param('sss', $name, $time, $body);        
$querya->execute();

Change this to mysqli_query($con,$querya); i.e. you don't have a $query variable. in the first if statement , Similarly do this mysqli_query($con,$queryb); on your elseif statement.

and add a semicolon here $stats = $_REQUEST['status']; //<------ as MillaresRoo and moonwave99 mentioned.

Add a semicolon here:

$stats = $_REQUEST['status'];

Line 46 should end with a semicolon:

$stats = $_REQUEST['status'] <---

By the way, you should use prepared statements.
