I often find this in scripts (and, I have to admit, write it myself):
a=`echo $x | sed "s/foo/bar/"`
or

Instead of:
if echo $x | grep foo then ...

Another option would be to use output....
If(true) { ?> Regular HTML Here <?php } else { ?> Regular HTML Here <?php }

You can simply break out of PHP in the if/else statement .

Printf() is a direct analogy....
Most PHP code that I've seen uses echo .
The only difference between echo and print in PHP the choice between echo and print pretty much comes down to style.
echo $var;
