No, I don't mean "always the same way." I'm talking about avoiding inconsistent indentation style like:

if (condition)
{
  code;
    other_code;
}
else {
   bork; }

if (condition_2) {
  foo;
}
else
  {
  i_think_you_get_what_i_mean();
  }

I don't peronsally mind if a block is on one line, as long as it's short. if (condition) { $foo=0; $bar++; } is perfectly fine. I mean consistency within a file, given the context. If you always put short blocks on one line, great. If you do something like

if (condition) { $foo=0; $bar++ }

# more code...

if (other_condition) {
    $foo++;
}

then I consider it to be inconsistent. And when I find inconsistent indentation it implies to me that your thinking isn't clear. This may or may not be the case -- it's more of an impression I get than an absolute rule.
