How to select the column in my database using my own API? [closed]

So I am trying to create an API for my personal project to fetch data. And it is working pretty nicely until I have to select a single column.

Here in this code I am trying to add the column parameter and then take data. I am using postman to check the API and when I send request, I get the complete table no matter what.

This is my index.php file.

<?php
include 'C:xampphtdocsphpAPIsincludeFilesdatabase.php';
include 'C:xampphtdocsphpAPIsincludeFilesredirectRequest.php';
include 'C:xampphtdocsphpAPIsincludeFilesprocessRequest.php';

$method = $_SERVER["REQUEST_METHOD"];
$url = trim($_SERVER["REQUEST_URI"], "/");
$urlParts = explode("/", $url);
var_dump($urlParts);
parse_str($_SERVER['QUERY_STRING'], result: $params);

header('Content-Type: application/json');

$database = $urlParts[2]; // Default database
$table = $urlParts[3]; // Table name
$column=$urlParts[4];


$pdo = new Database("localhost", "root", "", $database);
$redirect = new RedirectRequest($pdo);
$process = new ProcessRequest($redirect);

$process->handleRequest($method, $table, $column, $params);

?>

This is the handleGet method where I am passing the parameters to select the data from database.

    private function handleGet($table,$column, $params)
    {
        $limit = trim($params['limit'], '"') ?? 20;
        $orderBy = trim($params['orderBy'], '"') ?? null;
        $order = trim($params['order'], '"') ?? "ASC";
        
        $records = $this->redirectRequest->getAll($table, $column, $limit, $orderBy, $order);
        echo json_encode($records);
    }

And this is the redirectRequest.php where the SQL execution takes place:

    public function getAll($table, $column, $limit = 20, $orderBy = null, $order = "ASC")
    {
        $pdo = $this->database->getPDO();

        // Prevent SQL Injection in ORDER BY
        $order = strtoupper($order) === "DESC" ? "DESC" : "ASC";
        $orderByClause = $orderBy ? "ORDER BY `$orderBy` $order" : "";
        if($column==="all")
        {
            $column="*";
        }
        $query = "SELECT". $column ."FROM `$table` $orderByClause LIMIT :limit";
        $stmt = $pdo->prepare($query);
        $stmt->bindValue(":limit", (int) $limit, PDO::PARAM_INT);
        $stmt->execute();
        return $stmt->fetchAll();
    }

This is how I passed the request in the Postman:
https://localhost/testapi-v2-test/index.php/userlist/listall/animeid
and I get data from whole table.

Here ‘userlist’ is the database ‘listall’ is the table and ‘animeid’ is the column in the table. But even if I am passing this I get complete table returned to me. And if I pass this:

https://localhost/testapi-v2-test/index.php/userlist/listall/, I do get the error for the missing parameter as this:
 Warning: Undefined array key 4 in C:xampphtdocstestAPI-V2-testindex.php on line 16  and then the whole table is shown too
