What best practices should be followed when dynamically calculating column widths in PHP for a table?

When dynamically calculating column widths in PHP for a table, it is important to ensure that the columns are wide enough to accommodate the content without causing text to wrap or overflow. One approach is to iterate over the data to determine the maximum length of each column value, and then set the column width based on this maximum length. This ensures that the table is visually appealing and easy to read. 

// Sample data for demonstration
$data = array(
    array('Name', 'Age', 'City'),
    array('Alice', 25, 'New York'),
    array('Bob', 30, 'Los Angeles'),
    array('Charlie', 22, 'Chicago')
);

// Calculate maximum column widths
$columnWidths = array();
foreach ($data as $row) {
    foreach ($row as $key => $value) {
        $columnWidths[$key] = max(strlen($value), isset($columnWidths[$key]) ? $columnWidths[$key] : 0);
    }
}

// Output table with calculated column widths
echo '<table>';
foreach ($data as $row) {
    echo '<tr>';
    foreach ($row as $key => $value) {
        echo '<td style="width: ' . ($columnWidths[$key] * 10) . 'px">' . $value . '</td>';
    }
    echo '</tr>';
}
echo '</table>';
