PHP for loop: Exercise-17 with Solution

Write a PHP program to print alphabet pattern 'E'.

Visual Presentation:

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 (($row == 0 or $row == 6) and ($column > 1 and $column < 6)) or ($row == 3 and $column > 1 and $column < 5))
            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 uses 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 conditions:
• If the column is at index 1.
• If the row is at index 0 or 6 and the column is between indices 2 and 5 (inclusive).
• If the row is at index 3 and the column is between indices 2 and 4 (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 ?>.
