Of course it is possible to call a PHP-function inside an echo statement. The function will be executed and returns a value. This value then is used in the echo statement.
For example:
echo "Ferengi-Rule #1: ", ferengi_rule(1), "\n";
echo "Random: ", ferengi_rule(0), "\n";
function ferengi_rule($number)
{
$rules = array(
1 => "Once you have their money, never give it back.",
2 => "You can't cheat an honest customer, but it never hurts to try.",
3 => "Never buy anything for more than is absolutely necessary.",
4 => "Sex and profit are the two things that never last long enough."
// ...
);
if( isset($rules[$number]) )
{
return $rules[$number];
}
else
{
return array_rand($rules);
}
}

What is the difference between echo and print and printf in PHP?
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.
