Ah, you're right! The distinction completely slipped my mind!
I think the documentation is commenting on this here:
"You can prevent a recognized character in the format string from being
expanded
by escaping it with a preceding backslash. If the character with a backslash is
already a special sequence, you may need to also escape the backslash."
I took this to mean the backslash in a tab character would have to be escaped,
but on a second review, I understand what it's saying. It's a bit confusing.
Perhaps an example in the documentation would help clear things up. Or maybe
I'm just wrong. Anyway, if anyone hits this and wants to use double quotes,
you
can still do a t by typing \\t.

dillydadally I think you missed the fact that the original report had double-
quoted strings. Your version with single-quoted strings works as you would
expect.
eg.
php > echo date('H:m:s \m \i\s\ \m\o\n\t\h');
16:05:40 m is month

I whole-heartedly disagree that this is not a bug, as does the PHP.net
documentation itself! If you look at the documentation, "\t" is used all over
in the examples to represent how to type the letter t. For example, these are
copied from the documentation:
$today = date('\i\t \i\s \t\h\e jS \d\a\y.');
$today = date('H:m:s \m \i\s\ \m\o\n\t\h');
The backslash in the tab character should have to be escaped, so the tab
character should be \\\t. What's worse is this is not expected behavior and
there is no solution or note posted in the php documentation, leaving many
people confused.

That's because normal string escape rules still apply, and \t is the tab
character.

Description:
------------
When escaping with date("\t"), it shows up as nothing instead of 't'.
It seems to work fine with other characters, such as \a
Reproduce code:
---------------
<?php
echo "1: ". date("jS \of F Y H:i:s"). "<br />";
echo "2: ". date("jS \of F Y at H:i:s"). "<br />";
echo "3: ". date("jS \of F Y \at H:i:s"). "<br />";
echo "4: ". date("jS \of F Y \a\t H:i:s"). "<br />";
echo "5: ". date("jS \of F Y \t H:i:s"). "<br />";
?>
Expected result:
----------------
1: 2nd of September 2008 13:36:57
2: 2nd of September 2008 pm30 13:36:57
3: 2nd of September 2008 a30 13:36:57
4: 2nd of September 2008 at 13:36:57
5: 2nd of September 2008 t 13:36:57
Actual result:
--------------
1: 2nd of September 2008 13:36:57
2: 2nd of September 2008 pm30 13:36:57
3: 2nd of September 2008 a30 13:36:57
4: 2nd of September 2008 a 13:36:57
5: 2nd of September 2008 13:36:57
