How can radio buttons be effectively used in a PHP Sudoku generator for user interaction?

Radio buttons can be effectively used in a PHP Sudoku generator by allowing users to select a number to input into a specific cell on the Sudoku grid. This can provide a user-friendly interface for inputting numbers and help prevent input errors. By using radio buttons, users can easily see the available options and select the correct number for each cell. 

<?php
// Example code snippet for using radio buttons in a PHP Sudoku generator

// Loop through each cell in the Sudoku grid
for ($row = 0; $row < 9; $row++) {
    for ($col = 0; $col < 9; $col++) {
        // Display radio buttons for numbers 1-9
        echo "<input type='radio' name='cell[$row][$col]' value='1'>1";
        echo "<input type='radio' name='cell[$row][$col]' value='2'>2";
        echo "<input type='radio' name='cell[$row][$col]' value='3'>3";
        echo "<input type='radio' name='cell[$row][$col]' value='4'>4";
        echo "<input type='radio' name='cell[$row][$col]' value='5'>5";
        echo "<input type='radio' name='cell[$row][$col]' value='6'>6";
        echo "<input type='radio' name='cell[$row][$col]' value='7'>7";
        echo "<input type='radio' name='cell[$row][$col]' value='8'>8";
        echo "<input type='radio' name='cell[$row][$col]' value='9'>9";
    }
}
