Re: [PHP] Unix date (even more bazaar)
Spacing and/or control (unprintable) characters could easily be
messing you up.
Use something like:
$l = strlen($input);
for ($i = 0; $i $l; $i++){
echo $i: $input[$i] (, ord($input[$i]), )br /\n;
}
to see what you're getting.

As I feared, the email translation made both strings identical -- so
this won't work for those trying it.
BUT, I do have two strings that look identical but aren't.
I hate it when things like this happen.

Richard:
As usual, you are exactly right.
I found that somehow a gremlin had crept in -- I still don't
understand how, but it did. So, I stepped through the string similar
to what you did and replaced everything that wasn't supposed to be
there.
Interesting that making a text file with the string and looking at it
via a Hex Editor, I found that the gremlin was a 0A (new line), but
when it was on the server, it was two characters (High ASCII
194/160) -- very strange.
In any event, I fixed it. I didn't have the time to run down why.
Thanks,
tedd

Yeah, and to what bazaar are you going, old man? Look, I'm so loopy right now, I'm top-posting. How bizarre /Dan Ohhh, I hate it when that happens -- but, I have had even more embarrassing moments. As to the problem I posted about strings being different, it was a gremlin I found in the string. A hex edit of the file showed that the space between the date and time, which should have been a space (20) was actually a new line (0A) character. Oh well, at least I found it.

It requires PHP 5 = 5.1.0, hence the function_exists() condition.

Well, I'm glad it was easy for you, but this has been, and remains, confusing and frustrating for me. Shouldn't be... two different servers where the timezone in php.ini is set different. It does not do anything useful, EXCEPT giving you the possability to offset/ skew the time in php. Short version and a hand on explanation: Say I maintain a machine in seattle and my own here in norway. 9 hours time difference. These two is handling a site together and the database timestamp has to be the same, on a date not yet arrived on the other. I can now offset one of the machines 9 hour forth or back to fit my need. of course this only work if you handle one domain (or more in one country).

That was my problem to, till I found the bugger in the ini file: [Date] ; Defines the default timezone used by the date functions date.timezone = 0 that is the line you are looking for... or would if you had access to it. with the lines the other nice ppl provided, you do exactly the same, just not system wide.
