PHP - exit from IF block

You can't break if statements, only loops like for or while.

If this if is in a function, use 'return'.

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.

I cant believe no one have post this solution yet (writing it in my PHP style):

if($bla){do{
  $bla = get_bla();
  if(empty($bla)) break;
  do($bla);
}while(false);}

Complexity still O(1)

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
