 [2005-01-20 19:28 UTC] mnemo at minimum dot se 
Description:
------------
I wish "return doh" was treated like an expression when though this expression will never be computable.

The reason is that I want to write this:

mysql_connect(blah) or return false;

Just like I do with die etc.

That really isn't what return does because it's not a conditional.  Similar 
behaviour can be achieved by using: 

return (mysql_connect($blah) !== false) ? true : false;

binarycleric - that doesn't do the same thing in the slightest.

That would cause the return to run either way. What mnemo wants is for the return to happen ONLY if mysql fails.

Otherwise it should continue to the next line.

This works:

function foo() {}

mysql_connect(blah) or foo(false);

But this doesn't:

mysql_connect(blah) or return(false);

And I think it should.

This would make sense, I don't see why we couldn't make "return" an expression.

Then again, what's wrong with

  if (!mysql_connect(blah)) return false;
  
instead?

Thank you for your interest in PHP and for submitting a feature request. Please be aware that due to the magnitude of change this request requires, it would be necessary to discuss it on PHP Internals list (internals@lists.php.net) as an RFC. Please read the guide about creating RFCs here:
https://wiki.php.net/rfc/howto
If you haven't had experience with writing RFCs before, it is advised to seek guidance on the Internals list (http://php.net/mailing-lists.php) and/or solicit help from one of the experienced developers. 

Please to not consider this comment as a negative view on the merits of your proposal - every proposal which requires changes of certain magnitude, even the very successful and widely supported ones, must be done through the RFC process. This helps make the process predictable, transparent and accessible to all developers.
