Function Structure

[monkeypaw201]

im a bit confused on how functions work..

 

if i put

 

<?php
function example()
{
echo "hello world";
}

 

and farther along the page i put

 

<?php example() ?>

 

will that output

 

hello world

 

or do i need to put

 

<php echo example() ?>

 

?

If the function already echos, you don't need to do another echo. If the function returns the string, then you need to echo or print it.

either of them work....
