Some functions do act this way yes but not phpinfo, phpinfo() spits out
information and has no need for a print or echo.
function bar()
{
Return 'blah';
}
function foo()
{
print 'blah';
}
Now, bar() alone will not spit out the information but print bar() will.
People create functions this way for many reasons, one of which is to
allow for :
$var = bar();
Where $var is now equal the output of bar() which is 'blah'. Now if one
does just this :
foo();
It will spit out 'blah' and no echo or print is needed. But doing :
print foo();
Will also work but is not at all needed.
This is sorta how phpinfo works, it just spits out information for us.
Why am I using the word spit? Not sure :) Return can be read about here

Regarding the semi-colon discussion within this thread, it is not required
to make this work, see :
