Concatenation makes a slightly larger file, but it is:
1) Easier to read
2) More efficient when used with ' instead of "
If you use:
echo "row = $row!";
then you're forcing PHP to do the concatenation internally. It's
basically the same as:
echo 'row ='.$row.'!';
Only it takes more parsing when using ".
