yes it does but there isn't any good info around on how to make it work well.
from what I found searching through all the old posts and a few others sites the format should be
echo <<< EOF
blah di blah
stuff here
Someone says "I like php"
this var has a value of $var
EOF;
things to watch are taht you don't escape things and that you have the term string (EOF) at the left margin do not indent it. also you need a ; after the term string.
I use this because it's cleaner then any other way I've found.
