What best practices should be followed when deleting data in a PHP application connected to an Access database?

When deleting data in a PHP application connected to an Access database, it is important to follow best practices to ensure data integrity and security. This includes verifying user permissions, validating input to prevent SQL injection attacks, and using prepared statements to safely execute the delete query. 

<?php
// Connect to the Access database
$conn = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=path/to/your/database.accdb");

// Check user permissions
if($user->isAdmin()) {
    // Validate input
    $id = $_POST['id'];
    if(is_numeric($id)) {
        // Prepare and execute the delete query
        $stmt = $conn->prepare("DELETE FROM table_name WHERE id = :id");
        $stmt->bindParam(':id', $id, PDO::PARAM_INT);
        $stmt->execute();
        echo "Data deleted successfully.";
    } else {
        echo "Invalid input.";
    }
} else {
    echo "You do not have permission to delete data.";
}
?>
