date_default_timezone_set() Problem

[wwfc_barmy_army]

Hello.

I have been developing a site on my personal webserver on my computer but today i went to make it live on the net but i am getting this error on my server but not on my personal webserver:

[quote]Fatal error: Call to undefined function: date_default_timezone_set() in /home/rpgsfind/public_html/site.php on line 72[/quote]

It's with this bit of code:
[code=php:0]
<?php
date_default_timezone_set("US/Eastern");

list($year, $mon, $day) = explode('-', $qry[4]);

$sevenDays = (7 * 24 * 60 * 60); // 604,800 seconds in 7 days
$entryTime = strtotime("$year-$mon-$day");
$now = strtotime("now");

if (($now - $entryTime) < $sevenDays)
{
echo "<img src='images/new.gif'>";
}
?>
[/code]

Why isn't it working on the live server, do i need to change something? any advice is welcome.

Thanks.

Peter.

Make sure the PHP version you're using on the site is greater than or equal too Version 5.1.0

Create a file on the site called phpinfo.php and have it look like this:

[code]<?php
  phpinfo();
?>[/code]

When you run it, it should produce the info you're after.

Thanks for your reply i have version PHP Version 4.4.3. Is this the problem?

Thanks.

Yes, I'm afraid so.

If you look at the page in the manual for [url=http://uk.php.net/manual/en/function.date-default-timezone-set.php]date_default_timezone_set()[/url] you'll see it only works with versions later than 5.1.0

Ah, so whats the advantage of having php 4 over php 5 and is there a reason i shouldn't update?

Thanks.

There's no advantage of having php4 over php5, otherwise they wouldn't have released 5 :)

As for updating, as PHP6 development is well under way and PHP5 has been out for a long time, I'd say if you have the option to upgrade then do.  Unfortunately I don't have that option as I use hosted services as opposed to my own.

I'm sure others will come to the party and chip in their two cents if I've advised incorrectly though.
