How can multiple parent IDs be effectively managed in PHP when querying and displaying data from a database?

When dealing with multiple parent IDs in PHP when querying and displaying data from a database, you can use an array to store the parent IDs and loop through them to fetch and display the corresponding data. This approach allows for flexibility in handling multiple parent IDs efficiently. 

// Assume $parentIds is an array containing multiple parent IDs
$parentIds = [1, 2, 3];

// Loop through each parent ID to fetch and display data
foreach ($parentIds as $parentId) {
    // Query database for data related to $parentId
    $query = "SELECT * FROM your_table WHERE parent_id = $parentId";
    $result = mysqli_query($connection, $query);

    // Display data
    while ($row = mysqli_fetch_assoc($result)) {
        echo $row['column_name'] . "<br>";
    }
}
