I am a recent fan of the single-quotes. I used to use double only but when some gurus told me the disadvantages I converted my entire project over to single quotes. Single quotes are ideal because as far coding goes it greatly decreases the time of development when you don't have to worry about dropping in the escape character on your HTML values, etc. Granted, single quotes can be a nuisance in some instances (like when you need a new line character) but of course there is a way around. I simply define a constant and call that at the end of every line in order to substitute for the new line character.
Horizontal Tab - define("T", chr(9)); New Line - define("NL", chr(10));

I remember reading somewhere re: PHP coding that it is a better coding practice to use single quotes as much as possible vs. using double quotes in scripts. When using double quotes, you are forcing PHP to look for variables within them, even though there may not be any, thus slowing execution time...
For example it is better to code: Code: echo '<td bgcolor="'.$bgcolor2.'"> </td></tr>';
vs. Code: echo "<td bgcolor=\"$bgcolor2\"> </td></tr>";
Better is a very subjective question; however, style 1 will run faster since it won't look for variable interpolation. Personally I always use style 1 unless I specifically need variable interpolation or one of the special characters such as a newline. Also when doing HTML the double quotes fit nicely in the the single quote paradigm. On the other hand when I do SQL queries, I often allow interpolation just because it is more readable and because I usually use single quotes to wrap strings in my queries.
Now what is wrong with doing this?
echo '<td bgcolor="white"> </td>'."\r\n";
That way you can still use your single quotes and still being able to use the \r\n.. that does work doesnąt it? Im pretty sure I have used it before..
Anyways I guess the point is that you are not forced to use double quotes for the full echo just so you can use the special newline characters..
