[PHP] how to get consistent UTC from gmmktime (w/o dst-offset) ????
hi.
i'm storing events in a mysql-db, using epoch timestamps to pinpoint the
exact date/time for an event.
so far, I have been using localtime, being aware that there are
inconsistencies
in the number of epoch-seconds, when DST flips on and off. nevertheless, that
works fine as long as you stick to mktime() and date() for all the date-math
as in mktime(0,0,0,$month,$day+$offset,$year)
but as soon as you leave php and have to do some calculation in javascript,
you will encounter functions that behave differently on the pc and mac
platforms. so you have to revert back to the 'add 86400-seconds' to calculate
the next day.
so I thought it would be nice to have all the timestamps as linear,
non-dst-epoch-seconds (UTC) and I went into the gmmktime() and gmdate()
functions, assuming they would do the math in a linear second-based timespace
(in GMT, without DST). That seems to be the case for the output of 'gmdate',
that remains correct, if you count up seconds across the DST boundary (see
second example).
but it seems that there is no way to calculate the gmt-epoch for a given
date using gmmktime without having to add/subtract the TZ manually. gmmktime
will always take your local DST-settings into calculation and upon conversion
back with gmdate, you will be off by the number of hours of your timezone.
I thought gmmktime() would handle this as if the computer would be in
Greenwich
(TZ=0), which would then leave us with the two functions encoding/decoding
consistently.
anyone having solved this properly?

[PHP] help: form variables have CR/LF ?
Does anyone know what is going wrong, when all of a sudden, the content of PHP global variables that are generated from a POSTED form, have a CR/LF prepended? That means, looking at a field 'name' where 'john' was typed in, I'm getting a variable $name with the content ' john' instead of 'john' Anyone seen this I found that it only happens with the POST method. GET works fine (but I cannot use that). Any help is greatly appreciated. greets. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] help: form fields have CR/LF on submit
I submit a form with multipart/form-data, where a field 'name' contains let's say 'john'. On submit, I do get the expected global $name -variable but the content has a CR/LF or /n character in front of the actual content, like: ' john' instead of 'john'. Can anyone advise on this??? The script has been running on another machine so far without any problems, but upon moving it to a new server with php4, I started getting this bug. thanks greets -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

[PHP] how do i get url: response codes?
I've tried for a while now to figure out how to test from within php
if a url (http://xxx/file.html) is present and what error code is
returned (200,201,202,404, etc...)
the only way to test a url seems to be to open
file('http://xxx/file.html')
and see if it can be done. but that completely suppresses any error
codes and especially redirects. Has anyone figured out how to pull out
http error codes using php?
greets./

Re: [PHP] RE: [PHP-WIN] php XML output in IE: no display
IE does some intelligent guessing based on filename extension that will override headers. If you send enough headers in the right sequence you can get it to work right - with a weird name if you want to save it and sometimes a double query on whether or not you want to save it. Tricking it via PATH_INFO URLs works without any weird problems. I've just tried to fool IE into any mime (text/plain, image/gif, foo/bar) with the same content but it keeps ignoring it all on IE. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
