How can JSON_ARRAYAGG and JSON_OBJECTAGG functions in MySQL be utilized effectively when generating JSON output in PHP?

To utilize JSON_ARRAYAGG and JSON_OBJECTAGG functions in MySQL effectively when generating JSON output in PHP, you can query the database using these functions to aggregate the data into JSON arrays or objects. Then, you can fetch the result in PHP and encode it into a JSON format to be used in your application. 

<?php
// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Query to use JSON_ARRAYAGG and JSON_OBJECTAGG functions
$query = "SELECT JSON_ARRAYAGG(column_name) AS json_array, JSON_OBJECTAGG(key_column, value_column) AS json_object FROM table_name";

$result = $mysqli->query($query);

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $json_array = json_decode($row['json_array']);
        $json_object = json_decode($row['json_object']);
        
        // Use $json_array and $json_object as needed
    }
}

// Close database connection
$mysqli->close();
?>
