10. Multiplication Table 10x10

Write a PHP script that creates the following table (use for loops).

1	2	3	4	5	6	7	8	9	10
2	4	6	8	10	12	14	16	18	20
3	6	9	12	15	18	21	24	27	30
4	8	12	16	20	24	28	32	36	40
5	10	15	20	25	30	35	40	45	50
6	12	18	24	30	36	42	48	54	60
7	14	21	28	35	42	49	56	63	70
8	16	24	32	40	48	56	64	72	80
9	18	27	36	45	54	63	72	81	90
10	20	30	40	50	60	70	80	90	100

Sample Solution:

PHP Code:

<?php
// Start the HTML table with border attribute and collapsed borders style
echo "<table border =\"1\" style='border-collapse: collapse'>";

// Loop through rows
for ($row=1; $row <= 10; $row++) { 
    echo "<tr> \n"; // Start a new table row
    
    // Loop through columns
    for ($col=1; $col <= 10; $col++) { 
        // Calculate the product of column and row
        $p = $col * $row;
        
        // Print the product in a table cell
        echo "<td>$p</td> \n";
    }
    
    echo "</tr>"; // End the table row
}

// Close the HTML table
echo "</table>";

?>

Explanation:

In the exercise above,

PHP code begins with PHP tag <?php.
It starts by echoing out the start of an HTML table (<table>) with a border attribute set to "1" and a collapsed border style.
It then enters a nested loop structure:

The outer loop (for ($row=1; $row <= 10; $row++)) controls the rows of the table, iterating from 1 to 10.
Inside the outer loop, an inner loop (for ($col=1; $col <= 10; $col++)) controls the columns of each row, iterating from 1 to 10.

Within the inner loop, the product of the current row and column indices ($col * $row) is calculated and stored in the variable '$p'.
The product value '$p' is then echoed out within a table cell (<td>) in the HTML table.
After completing each row, the code echoes out </tr> to close the table row (<tr>).
Once all rows and columns are populated with the products, the PHP code closes the HTML table with </table>.
Finally, the PHP code ends with a closing PHP tag ?>.
