PHP for loop Exercises: Print alphabet pattern Z

Sample Solution:

PHP Code:

<?php
// Loop for rows
for ($row=0; $row<7; $row++)
{
    // Loop for columns
    for ($column=0; $column<=7; $column++)
    {
        // Condition to determine whether to print '*' or ' '
        if ((($row == 0 or $row == 6) and $column >= 0 and $column <= 6) or $row+$column==6)
            echo "*";    // Print '*' if condition is met
        else  
            echo " ";    // Print ' ' if condition is not met
    }        
    echo "\n";    // Move to the next line after each row is printed
}
?>

Output:

Explanation:

In the exercise above,

The code starts with a PHP opening tag <?php.
It utilizes a nested loop structure to iterate over rows and columns to create a specific pattern.
The outer loop (for ($row=0; $row<7; $row++)) controls the rows of the pattern, iterating from 0 to 6.
Inside the outer loop, there's another loop (for ($column=0; $column<=7; $column++)) that controls the columns, iterating from 0 to 7.
Within the inner loop, there's a conditional statement that determines whether to print an asterisk ('*') or a space ( ) based on the position of the current row and column indices.
The condition checks multiple cases:

If the row is at index 0 or 6 and the column index is between 0 and 6, inclusive.
If the sum of the row index and column index equals 6.

If any of these conditions are met, an asterisk ('*') is echoed. Otherwise, a space ( ) is echoed.
After printing each row, the code moves to the next line by echoing a newline character ('\n').
Once all rows and columns are printed according to the pattern, the PHP code ends with a closing PHP tag ?>.
