That's what I do with 'em, and that's exactly why. Can't stand to  
have things not "look right", even if it does cost a function call.


At least until costing a function call matters more than being able  
to change things without going cross-eyed.

All editors display something other than what is actually there, to
some degree... :-)

That said...

The problem with the editor auto-indenting lines that aren't indented
is what to do with lines that ARE indented...

True Source:
$email = EOM
  This is a paragraph that has been indented and
hard line-wrapped with something not unlike:

http://php.net/wordwrap
and has had URLs embedded in ways to make sure ALL
email clients will present at least ONE clickable link,
even the dreaded AOL 4.0
  Yes, I still have code that is hanging around
from when AOL 4.0 was "new".
  Sorry.
EOM;

So what would your nifty editor do with that?

Indent it to match PHP indenting, and then add the whitespace of the
actual message?

I think that might "work" well, though lead to a lot of un-readable
right-shifted long text lines instead of the "ugly" indentation.

One think you could consider to avoid the ugliness is to put the
heredoc into a one-use function or in an incldue file that doesn't
have enough indenting for it to look ugly in the first place. :-)

You could use a silly editor from Microsoft, and then run it using Wine.

"something other than what is actually there"

Not at all, Rob! Have you seen how many editors dynamically wrap lines
(Quanta on KDE for instance)? Instead of placing the wrapped line right
smach along the left edge, it indents the following lines under the
first line. It is visually clear that there is no extra white space
because the extra indent has a different background color.

Like this (I used +'s to indicate a different background color, telling
you this isn't whitespace in your code):

if($something){
   $variable = "This text message goes on and on and ever on and and
+++would run right off the edge of my screen but thankfully my editor
+++is smart enough to wrap the lines in a way that also does not
+++ruin the indentation.\n";
}

Now, I would wish for my editor to also indent multi-line strings in the
same fashion. Essentially, the lines of $sql_ugly in my example above
should be displayed in alignment with the indentation:

if($something){
   if($something_else){
  $myID = intval($_GET['rowID']);
  $sql =
++"SELECT
++   field1,
++   field2
++FROM
++   mytable
++WHERE
++   rowID = $myID";
}
}

I doubt Microsoft develops an editor that I could use on my Linux system
for this...

Cheers,

Mattias

Then you'd have an editor that presents something other than what is
actually there. Go see Microsoft, I'm sure they create rubbish like
that.

Exactly. I never saw the point in complicating my life with heredocs
when both single- and double-quoted strings can contain multiple lines
anyway.

One thing that does bother me a little with multi-line strings of either
variety is that if I want to avoid inserting extra spaces in the string
at the beginning of each line after the first, I have to left-align the
whole thing and cannot indent it with the rest of my code:

if($something){
if($something_else){
   $myID = intval($_GET['rowID']);
   $sql_pretty =
"SELECT
field1,
field2
 FROM
mytable
 WHERE
rowID = $myID";
$sql_ugly =
"SELECT
field1,
field2
FROM
mytable
WHERE
rowID = $myID";
}
}

Are there perhaps editors that would DISPLAY multi-line quoted strings
"indented" to the correct level without inserting extra spaces? Some
editors wrap lines to the correct level, which is also much more
readable, so what I'm thinking of is a bit similar to that.

Bash uses only 2. PHP uses 3. And I am using this:

$sql="

from 
left join ...
