Class that performs basic CRUD operations

<?php

class DataBase 
{
    
    protected $connection;

    public function __construct($host, $db, $user, $pass, $charset = 'utf8mb4', $options = []){
        $options = array_merge([
            PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
            PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
            PDO::ATTR_EMULATE_PREPARES   => false,
        ], $options);
        $dsn = "mysql:host=$host;dbname=$db;charset=$charset";
        try {
            $this->connection = new PDO($dsn, $user, $pass, $options);
        } catch (\PDOException $e) {
            throw new \PDOException($e->getMessage(), (int)$e->getCode());
        }
    }


    public function getData($table, $column, $value){
        $data = $this->connection->prepare(sprintf("SELECT * FROM %s WHERE %s = ?", $table, $column));
        $data->execute([$value]);
        return $data->fetch();
    }
    

    public function insert($table, $data){
        $columns = implode(', ', array_keys($data));
        $placeholders = implode(', ', array_fill(0, count($data), '?'));
        $query = sprintf("INSERT INTO `%s` (%s) VALUES (%s)", $table, $columns, $placeholders);

        foreach($data as $key => $value){
            $set_statement .= sprintf("`%s` = ?, ", $key);
        }

    }

    $db   = 'DBNAME';
    $user = 'USERNAME';
