php - How to create a nested loop and display the result in 3 columns?

Get the solution ↓↓↓

Solution:

The outer loop is for rows, the inner loop is for columns. So you should print<br/> in the outer loop. And since you want$x printed in each column, you need to print that in the inner loop.

for ($x = 0; $x < 4; $x++) {
    for($y = 0; $y < 3; $y++){
        echo "$x($y) ";
    }
    echo "<br/>";
}
