Generic expressions interpolation in strings

I already opened a bug (#21433) about this Feature Request, but I realized it is better to discuss here about it. I'm relatively new to PHP. Previously I used to program a lot in Perl. What I really lack in PHP is Perl's ability to interpolate any expression inside a string. For example: Perl: "Next value is @{[ $value + 1 ]}!" PHP: "Next value is " . $value + 1 . "!" In this simple case it's not a great problem, but it becomes more awkward when using the heredoc operator. In this cases I'm often forced to use temporary variables: $tempvar = $value + 1; print <<< END Here it is the next value $tempvar Other text... END; I propose to extend the Variable Parsing syntax to evaluate ANY expression instead of variables only. I propose the following syntax: print <<< END Here it is the next value {$= $value + 1 } Other text... END; Using "{=" would be more readable but it would cause too many backward compatibility problems... What do you think of this? Thanks. -- ___________________________________________________ __ |- giannici@neomedia.it |ederico Giannici http://www.neomedia.it ___________________________________________________
