[PHP-DB] Dates prior to Dec 31, 1969
I'm using the following code to display dates returned from a query of a
mySQL database.
$new_timestamp = strtotime($row_SearchPlayerRcrdSt['Date']);
$new_date_formatted = date ("m/d/y", $new_timestamp);
echo $new_date_formatted;
It appears that all dates prior to Dec 31, 1969 are displayed as 12/31/69.
What am I doing wrong?
Thanks,
Frank

Hi there everyone,
I am having to read a string with text in, but the way the DB is written in

this doesn't sound like a DB problem, sounds more like a regexp problem.
(i.e. php-db is probably the wrong list)
CASARON 4G
50lb Sacks in Ton Lots
$88.00
How can I strip out the 88.00 (Baring in mind it could be any number) into
it’s own string?
http://nl2.php.net/manual/en/ref.pcre.php
NB: note the difference between using single and double quotes when
defining your regexp. e.g:
$regexp = '/^.*\$[ \t]?([0-9]+\.[0-9]{2})$/s';
and:
$regexp = "/^.*\$[ \t]?([0-9]+\.[0-9]{2})$/s";
...are not the same.
assuming that the price is at the end of the string you and is preceeded
by a dollar sign (with or without a seperating space) could do:
$myString = "
CASARON 4G
50lb Sacks in Ton Lots
$88.00
\r\n
\t\r\n
";
$matches = array();
$found = preg_match(
'/^.*\$[ \t]?([0-9]+\.[0-9]{2})$/s',
/* some commented out alternatives */
// '/^.*\$([0-9]+\.[0-9]{2})$/s',
// '/^.*\$([0-9]+\.00)$/s',
// '/^.*\$(88\.00)$/s',
// '/.*\$(\d+\.\d+)/s',
trim($myString), /* make life easier have a trim */
$matches /* passed by ref */
);
print_r("original string:\n--\n$myString");
print_r("\n\ntrimmed string:\n--\n".trim($myString)."\n\n");
print_r("found: $found\n matches array contents:\n\n");
print_r($matches);
?>
Thank you.
Chris

What kind of field is it? (int,timestamp,datetime,etc)
$new_timestamp = strtotime($row_SearchPlayerRcrdSt['Date']);
what do the following contain:
$new_timestamp
$row_SearchPlayerRcrdSt['Date']
you also might want to try connecting to the DB with the cmdline
mysql app to take a look at the date values actually stored in the DB.
$new_date_formatted = date ("m/d/y", $new_timestamp);
echo $new_date_formatted;
It appears that all dates prior to Dec 31, 1969 are displayed as 12/31/69.

Sounds like you have yet to come across the 'unix epoch' (try googling
that). something to do with this looks to be tripping you up.
Either the date in the DB is invalid (eg. equal to 0) or strtotime or
date are truncating the date value in your version of php.
(what version of php & mysql?)
Also notice that you are taking a formatted date string, parsing it for
a timestamp and then creating a new formatted date string. Why not let
mySQL just format it how you want straight away and save 2 function calls?
Thanks,
Frank

On my system it displays at 01/01/70. This may be related to that note
in the strtotime page of the php manual:
http://ww.php.net/manual/en/function.strtotime.php
Note: The valid range of a timestamp is typically from Fri, 13 Dec
1901 20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT. (These are the
dates that correspond to the minimum and maximum values for a 32-bit
signed integer.) Additionally, not all platforms support negative
timestamps, therefore your date range may be limited to no earlier
than the Unix epoch. This means that e.g. dates prior to Jan 1, 1970
will not work on Windows, some Linux distributions, and a few other
operating systems.
How about letting MySQL format the date for you?

[PHP-DB] Turn off "out of offfice" messages for the list, please
List, I'm sure many of us will be taking some time off for the holidays (if you aren't already). Just a friendly reminder to either 1) unsubscribe while you're gone (you won't miss much, trust me) or 2) set your notice to not reply to postings to the list. These get quite annoying after a while, if you can imagine. Yes, I know how to filter them to my Junk folder, but let's try to stop it at the source instead, eh? ;) Happy Holidays, -- ---John Holmes...
