What are some alternative approaches to structuring and querying data in PHP to avoid issues with displaying zero values in a table format?

When displaying data in a table format in PHP, zero values can sometimes cause readability issues. One approach to avoid this is to replace zero values with a placeholder text such as "N/A" or an empty string. Another approach is to use conditional statements to only display non-zero values in the table. 

// Sample data array with zero values
$data = [
    ['name' => 'Alice', 'age' => 0],
    ['name' => 'Bob', 'age' => 25],
    ['name' => 'Charlie', 'age' => 0],
];

// Display data in a table format with zero values replaced by "N/A"
echo '<table>';
echo '<tr><th>Name</th><th>Age</th></tr>';
foreach ($data as $row) {
    echo '<tr>';
    echo '<td>' . $row['name'] . '</td>';
    echo '<td>' . ($row['age'] != 0 ? $row['age'] : 'N/A') . '</td>';
    echo '</tr>';
}
echo '</table>';
