How can I exit a if block if a certain condition is met?

I tried using break but it doesn't work:

if($bla): 
  $bla = get_bla();
  if(empty($bla)) break;
  do($bla);
endif;

it says: Fatal error: Cannot break/continue 1 level in...


Why not just turn it around.

if($bla): 
  $bla = get_bla();
  if(!empty($bla)) {
    do($bla);
  }
endif;

That way it will only run your code if $bla isn't empty.. That's kinda the point with if-statements

break - Manual, break ends execution of the current for, foreach, while, do-while or switch structure. This caught me out when I mistakenly had a break in an if statement i.e. A side-note for the use of exit with finally: if you exit somewhere in a try block, the finally won't be executed. Could not sound obvious: for instance in Java you never issue an exit, at least a return in your controller; in PHP instead you could find yourself exiting from a controller method (e.g. in case you issue a redirect).


In PHP 5.3 you can use goto

if($bla): 
   $bla = get_bla();
   if(empty($bla)) goto end;
   do($bla);
endif;
end:

But personally I think that's an ugly solution.
