# PHP for loop Exercises: Print alphabet pattern A

## PHP for loop: Exercise-13 with Solution

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

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 if '*' or ' ' should be printed
if (((\$column == 1 or \$column == 5) and \$row != 0) or ((\$row == 0 or \$row == 3) and (\$column > 1 and \$column < 5)))
echo "*";    // Print '*' if conditions are met
else
echo " ";    // Print ' ' if conditions are not met
}
echo "\n";  // Move to the next line after each row is printed
}
?>
```
```

Output:

```  ***
*   *
*   *
*****
*   *
*   *
*   *
*   *
```

Explanation:

In the exercise above,

• The code begins with a PHP opening tag <?php.
• It uses a nested loop structure to iterate over rows and columns to create a pattern.
• The outer loop (for (\$row = 0; \$row <= 7; \$row++)) controls the rows of the pattern, iterating from 0 to 7.
• Inside the outer loop, there's another loop (for (\$column = 0; \$column <= 7; \$column++)) that controls the columns by 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 whether the current position corresponds to the desired pattern of asterisks and spaces.
• If the condition is 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 ?>.
