How can you convert database data showing only IDs into readable content in PHP?

When database data only shows IDs, we need to retrieve the corresponding readable content from another table that maps IDs to their respective values. This can be achieved by performing a JOIN query in PHP to fetch the necessary data and then display it in a readable format. 

// Assuming $db is your database connection object

// Query to retrieve data from the main table with only IDs
$query = "SELECT main_table.id, main_table.name, mapping_table.value 
          FROM main_table 
          JOIN mapping_table ON main_table.id = mapping_table.id";

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

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "ID: " . $row['id'] . ", Name: " . $row['name'] . ", Value: " . $row['value'] . "<br>";
    }
} else {
    echo "No results found.";
}
