ok, it slices and dices, but how?
in python, to print all but the last char in string FOO, we say
print FOO[:-1]
But this seems to bark like a basset hound in php. Whyfore?

Now tihs tyro is seeking sage words to help me understand this.
RTFM is not sage words; if you don't want to help me please don't waste

Would anyone care to help me understand this without dedicating 4

print substr($foo, 0, -1);

You could also do this, but it takes more code:
print substr($foo, 0, strlen($foo) - 1);

You could wrap it as a function like so:
function strchop($string, $num_chars_to_chop_off_end)
{
return substr($string, 0, -$num_chars_to_chop_off_end);
}

If you have time, the relevant manual page is:

[PHP] add one day to DateTime based on timestamp

[Shailesh N. Humbad]

Hello,

When I create a DateTime object from a UNIX timestamp, and then add a 
one day interval, PHP adds 25 hours instead of 24.  Is this a bug, or 
something to do with the time zones?


Here are the commands I'm running from my shell:

--

$ date

Wed Jun 13 06:08:24 PDT 2012

$ php -r '$d=new DateTime(@108200); print $d-format(r).\n; 
$d-add(new DateInterval(P1D)); print $d-format(r).\n;'

Wed, 21 Apr 2004 08:00:00 +

If I set the time zone on the new DataTime object to America/Los_Angeles 
before adding the 1 day period, then it works as expected.


--

$ php -r '$d=new DateTime(@108200); $d-setTimeZone(new 
DateTimeZone(America/Los_Angeles)); print $d-format(r).\n; 
$d-add(new DateInterval(P1D)); print $d-format(r).\n;'
