PHP for loop Exercises: Print alphabet pattern H

Sample Solution:

PHP Code:

 <?php
// Loop for rows
for ($row=0; $row<7; $row++)
{
    // Loop for columns
    for ($column=0; $column<=7; $column++)
    {
        // Condition to determine whether to print '*' or ' '
        if (($column == 1 or $column == 5) or ($row == 3 and $column > 1 and $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
}
?>

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 three cases:

If the column is at index 1 or 5.
If the row is at index 3 and the column is between indices 2 and 5 (inclusive).

If any of these conditions are met, an asterisk ('*') is echoed out. Otherwise, a space ( ) is echoed out.
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 ?>.
