what does '$[[variable]]' mean?

[mrherman]

Found this on Snipplr the other day.  It looked interesting and was under the heading of "sticky nav."

 

<?php

if ( $[[variable]] == '[[value]]' )
{
   echo 'class="act"' ;
}

?>

 

Could someone explain this?

 

Thanks.

It's invalid when treated as php code. It's more likely that it is something out of a template system. A few lines of code, out of context, is generally meaningless. What script is this part of and what is the code surrounding it doing?

OK, thanks very much.  That is all I know--no contextual code was given.  I was thinking that perhaps the '$[[variable]]' was, by itself, a PHP structure.

 

Will mark as solved.
