# PHP for loop Exercises: Print alphabet pattern L

## PHP for loop: Exercise-24 with Solution

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

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 == 6 and \$column != 0 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
}
?>
```
```

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 two cases:
• If the column is at index 1.
• If the row is at index 6 and the column is not at index 0 and is less than 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 ?>.
