How can the number of rows and columns in a loop be dynamically changed using variables in PHP?

To dynamically change the number of rows and columns in a loop using variables in PHP, you can simply assign the desired values to variables before the loop and then use those variables as the loop conditions. This allows you to easily adjust the number of iterations based on the variables' values. 

<?php
$rows = 3; // Number of rows
$columns = 4; // Number of columns

for ($i = 1; $i <= $rows; $i++) {
    for ($j = 1; $j <= $columns; $j++) {
        echo "Row: $i, Column: $j\n";
    }
}
?>
