What's the difference between single and double quotes in EZ templates?

Is it the same way as in PHP?

That's a good question Marko.

Marco, I think what Marko is asking is, whether eZ publish uses the same set of evaluation procedures for single quotes and double quotes as PHP. Within PHP, a string contained in single quotes will not be evaluated for variables, whereas a string in double-quotes will be evaluated. So, if you have a plain-text string, that has no variables, it is faster to use single quotes for it. If eZ publish's template markup does follow the same pattern, it may well affect rendering speed and whether or not variables are read properly.

Marko, from my experience, I do not think that eZ publish acknowledges any difference between single and double quotes, though someone else may be able to provide a more definitive answer.

Yep Alex, that was exactly what I was asking. I'll stick with your opinion until someone gives a "more definite answer".

Thx.

Although I'm not from the ez crew

The bottom line: there is no difference in handling between single or double quotes. Did you try this in some scenario?

I can come up with two "places"

{let} {set} {default} constructs: you cannot put variables in a string, it won't be parsed. Eg

<!--
{let registration_count=12
      string_single = 'single $registration_count'
      string_double = "double $registration_count" }

{$string_single} and {$string_double}
{/let}
-->

Will output the verbatim strings:

<!--
single $registration_count and double $registration_count
-->

Second scenario: when you put variables inside strings like in

<!--
{let registration_count=12}
<p>'Hi there {$registration_count}'</p>
<p>"Hi there {$registration_count}"</p>
-->
{/let}

Will output

<!--
<p>'Hi there 12'</p>
<p>"Hi there 12"</p>
-->

And you cannot nest {}, for example {'Hi there, we've got {$registration_count} registrations'} is illegal (you really do not get what you may think.
