I have traditionally used double quotes going back to my PASCAL days. I see many PHP examples using single quotes, and I began to adopt that convention. Even updating existing code. And I broke some stuff that was doing variable expansion. So I am back to using double quotes. But I wonder, is there any reason to use single quotes? Stephen

Because sometimes it is nice to do this: $onclick = ' onclick="..."' Not having to escape my single tick makes it more readable.

Now *that's* a good reason... anything that means fewer \'s or \"s. I often go for HEREDOC syntax if the backslashes start taking over - readability is much more important to me than nanoseconds of performance. There's also the case where you might want literal $s in your string: e.g. $foo = 'You need to pay $dollars...'; compared with $foo = "You need to pay \$dollars..."; Again, it depends on you view of backslashes. -- Peter Ford phone: 01580 893333 Developer fax: 01580 893399 Justcroft International Ltd., Staplehurst, Kent
