There is a difference between the two, but speed-wise it
should be irrelevant which one you use. print() behaves
like a function in that you can do:
$ret = print "Hello World";
And $ret will be 1
That means that print can be used as part of a more complex
expression where echo cannot. print is also part of the
precedence table which it needs to be if it is to be used
within a complex expression. It is just about at the bottom
of the precendence list though. Only "," AND, OR and XOR
are lower.
echo is marginally faster since it doesn't set a return
value if you really want to get down to the nitty gritty.
