[TriLUG] new PHP question - what's up with join()?

[David Rasch]

join takes an array as the second parameter:

$fullName = join(' ', array($firstname, $lastname));
echo "$fullName<br>";

note that perl will only pass to a function an array of scalars, while
php can actually take a set of parameters including arrays, objects, and
scalars.
