Unable to insert data to table in sqlite using pdo [duplicate]

Can someone please help me with this? I am trying to insert the data into the database. I have checked the location of the database to be correct. Also there are no error after executing the query. However, no data has been added to the table. How can i solve this.

<?php

$db = new PDO('sqlite:../cart.db');
$db->query('PRAGMA foreign_keys = ON;');

if($q = $db->prepare("INSERT INTO CATEGORIEy (CATID, NAME) VALUES (?, ?)")) {

    $q->bindParam(1, $catid);
    $q->bindParam(2, $name);
    $catid = 1;
    $name = "test";
    $q->execute();

    echo "end";
    
}else{
    var_dump($db->errorInfo());
}


?>
