PHP Output Demo

echo says: Hello, world!

This example shows multiple echo parts combined.

print outputs text and returns 1.

(Because print returned 1, this line also displays.)

printf() example: Notebook × 3 = $13.50

print_r() example (array output):

Array
(
    [item] => Notebook
    [price] => 4.5
    [qty] => 3
    [total] => 13.5
)
