How to perform database queries in Phalcon?

Phalcon is a PHP web application framework that provides a set of tools and libraries for building web applications. To perform database queries in Phalcon, you can use the built-in ORM (Object-Relational Mapping) system, which provides a set of classes and methods for interacting with databases.

Here's an example of how to perform a simple database query in Phalcon using the ORM:

use PhalconMvcModelQuery;

// Create a new query object
$query = new Query(
    "SELECT * FROM users WHERE status = :status:",
    $di
);

// Bind the parameters
$parameters = [
    "status" => "active",
];
$query->setVars($parameters);

// Execute the query
$results = $query->execute();

// Loop through the results and do something with them
foreach ($results as $user) {
    echo $user->name . "
";
}

In this example, we create a new Query object, which takes two arguments: the SQL statement and the dependency injection container ($di). We then bind the parameters using the setVars method and execute the query using the execute method. Finally, we loop through the results and do something with them.

Of course, this is just a simple example. Phalcon's ORM provides a rich set of features for performing complex database queries, such as filtering, sorting, grouping, and joining data from multiple tables. You can learn more about the ORM in the official Phalcon documentation.
