Why can't I connect to database using PHP Slim framework? - php

Question

I'm new to PHP Slim framework and I've written code to connect to database but it shows the following error in console (The database exists, still getting error):
Here's my code:
<?php
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
require '../vendor/autoload.php';
function dbConnect(){
$host='127.0.0.1';
$user='root';
$pass='';
$dbname='testdbmysql';
$pdo= new PDO("mysql:host=$host; dbname= $dbname", $user, $pass);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
return $pdo;
}
$app = new \Slim\App;
$app->post('/hello/{id}', function (Request $request, Response $response, $args) {
echo "hello";
$names = $request->getParsedBody();
$db=dbConnect();
$names_arr=[];
$names_arr['name1']= filter_var($names['name1'], FILTER_SANITIZE_STRING);
$names_arr['name2']= filter_var($names['name2'], FILTER_SANITIZE_STRING);
$response->getBody()->write("Hello , ".$names_arr['name1']);
$query=mysqli_prepare($db, "INSERT into info(fname, lname) VALUES(?, ?)");
mysqli_stmt_bind_param($query, "ss", $names_arr['name1'], $names_arr['name2']);
$result=mysqli_stmt_execute($query);
$rows=mysqli_stmt_insert_id($query);
echo "Rows: ".$rows;
return $response;
});
$app->run();
?>
When I searched on Internet, I found solutions to same error caused by Laravel framework, but not about Slim. Is there something I can do?

You should remove the whitespace
$pdo= new PDO("mysql:host=$host; dbname=$dbname", $user, $pass);
The error output is displaying the whitespace, too. So that should be the mistake.
Also, do not Mix up PDO and mysqli. You are passing a PDO-Connection to mqsqli functions, thats why you get " Expected mysqli, got PDO."
I would stick with mysqli and set up a connection via mysqli_connect().
