Last update on December 20 2024 10:17:58 (UTC/GMT +8 hours)

Write a PHP program to print out the multiplication table upto 6*6.

Sample Solution:

PHP Code:

<?php
// Outer loop for rows
for ($i = 1; $i < 7; $i++) {
    // Inner loop for columns
    for ($j = 1; $j < 7; $j++) {
        // Check if it's the first column
        if ($j == 1) {
            // Display the product of $i and $j, left-padded to 2 characters
            echo str_pad($i * $j, 2, " ", STR_PAD_LEFT);
        } else {
            // Display the product of $i and $j, left-padded to 4 characters
            echo str_pad($i * $j, 4, " ", STR_PAD_LEFT);
        }
    }
    // Move to the next line after each row is printed
    echo "\n";
}

?>

Explanation:

Outer Loop for Rows:

for ($i = 1; $i < 7; $i++) iterates from 1 to 6, representing each row.

Inner Loop for Columns:

for ($j = 1; $j < 7; $j++) iterates from 1 to 6 for each column within the current row.

Display Values Based on Column Position:

If $j == 1 (first column), it displays the product of $i * $j, left-padded to 2 characters.
For other columns ($j > 1), it displays the product of $i * $j, left-padded to 4 characters.

End of Row:

echo "\n" moves to the next line after each row is printed, creating a new row in the output.

Output:

1   2   3   4   5   6                                      
 2   4   6   8  10  12                                      
 3   6   9  12  15  18                                      
 4   8  12  16  20  24                                      
 5  10  15  20  25  30                                      
 6  12  18  24  30  36
