It is a string concatenation in PHP. But, as my last email on this
thread shows, you only need to add ENT_QUOTES to your htmlentities()
call and everything will work.

If you use single quotes you can't use variables inside the string. You
have to combine strings and variables or two strings with a dot.

echo 'foo'.$bar;

I'm not shure but I think to validate xhtml you need the double quotes.

Problem I'm having is I've inherited a PHP page that contains sections of PHP/Javascript/HTML/CSS all inside of a PHP echo tag. My PHP and JS skill are rudimentary at best so when it comes to a block of code 40 to 50 lines in length, it becomes daunting to reverse the ' with ". Each echo block starts with a " and the html inside uses a '. JS also uses '.

Below is an actual block in more detail with JS in it. Is it still recommended to switch with " with ' and ' with "?

--Rick


echo "
<p>Click on a picture to view that color:</p>";
If (trim($pic_1) <> "") {echo "<div class='proddetailpics'><a href='#' class='color_thumb'> <img src='/imagedir/$pic_1' alt='$itemgroup $itemsubgroup' width='60' height='60' onclick=MM_swapImage('prodimage','','/imagedir/$pic_1',0) border='0' /></a></div>";}
If (trim($pic_2) <> "") {echo "<div class='proddetailpics'><a href='#' class='color_thumb'> <img src='/imagedir/$pic_2' alt='$itemgroup $itemsubgroup' width='60' height='60' onclick=MM_swapImage('prodimage','','/imagedir/$pic_2',0) border='0' /></a></div>";}
If (trim($pic_3) <> "") {echo "<div class='proddetailpics'><a href='#' class='color_thumb'> <img src='/imagedir/$pic_3' alt='$itemgroup $itemsubgroup' width='60' height='60' onclick=MM_swapImage('prodimage','','/imagedir/$pic_3',0) border='0' /></a></div>";}

If (trim($pic_5) <> "") {echo "<div class='proddetailpics'><a href='#' class='color_thumb'> <img src='/imagedir/$pic_5' alt='$itemgroup $itemsubgroup' width='60' height='60' onclick=MM_swapImage('prodimage','','/imagedir/$pic_5',0) border='0' /></a></div>";}

That's some damn ugly code that I'd consider putting in a loop right
away!
