How can PHP developers optimize the efficiency of their code when implementing weighted calculations for column widths in dynamic tables?

When implementing weighted calculations for column widths in dynamic tables, PHP developers can optimize the efficiency of their code by using a loop to calculate the total weight of all columns first, then calculating the width of each column based on its weight relative to the total weight. This approach ensures that the columns are sized proportionally according to their weights.

// Define the weights for each column
$column_weights = [1, 2, 3, 1];

// Calculate the total weight of all columns
$total_weight = array_sum($column_weights);

// Calculate the width of each column based on its weight
$column_widths = [];
foreach ($column_weights as $weight) {
    $column_widths[] = round(($weight / $total_weight) * 100, 2) . '%';
}

// Output the column widths
foreach ($column_widths as $width) {
    echo '<th style="width: ' . $width . ';">Column</th>';
}
