Build an array and use in_array():
$redirect_me = array ('212.3.54.65', '127.0.0.1', '192'168.0.1');
if (in_array ($_SERVER['REMOTE_ADDR'], $redirect_me))
{
header ("Location: ...");
exit;
}
If the addresses you are targeting are ranges in CIDR format (e.g.
192.168.0.0/24), take a look at the PEAR package Net_IPv4.

Interesting -- more portable since the month names would then follow
locale settings.
Plus it paves the way for a really hairy one-liner. With apologies to
the original poster for the drift and the perversity of this example:
".implode("\n",array_map(create_function('$n','return"".strftime("%b",strtotime("2004-$n-01"))."";'),range(1,12)))."";

Here's how I might re-do your code (notes below):
$months = array ('', 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul',
'Aug', 'Sep', 'Oct', 'Nov', 'Dec');
print "";
foreach ($months as $number => $month)
{
$selected = "";
if (date ('n') == $number)
{
$selected = "selected='selected'";
}
print "$month";
}
print "";
Notes (warning, many personal biases included):
1. Quote all HTML attributes.
2. Use XHTML-compatible markup for "selected" attribute, nutty as it looks.
3. Use the month name, not the number, for your display values.
4. If you want a blank "option" entry, you might as well include it in
your array.
5. Avoid iterating through arrays with C-style "for" loops; "foreach"
is cleaner.
6. Don't continually switch between PHP and HTML modes; either write
PHP that prints HTML, or use templates.
7. Use blocks in "if" statements.
8. Use Whitesmiths brace style :)

An alternative solution is to insert a small delay using usleep() after each message is sent such that the queue never gets overfull to begin with. Also, keep in mind you are dealing with multiple possible constraints -- local resource limitations (CPU & disk), and bandwidth available for connecting to remote hosts. For reference, I do this kind of thing on a fairly busy server, using Postfix, for nonprofit clients that do member newsletter mailings in the 5,000 to 10,000 piece range. I find that I am able to keep system load tolerably low by limiting my script to about 3-4 messages per second. In my case I am mostly concerned about managing local CPU. The queue never backs up. You will also want to look at protecting your script from dying prematurely by using ignore_user_abort() and set_time_limit() or equivalents. If you are sending only a few hundred messages, that shouldn't place much of a burden on your server, and you may not need to insert any delay at all. (Whereas if you are sending 100,000 messages, I'd have to guess you're a spammer, as any org with a legitimate reason to mail 100K people at once would be unlikely to be creating this script from scratch and asking basic questions in php-general. But I could be wrong.) good luck, pb -- paul bissex, e-scribe.com -- database-driven web development 413.585.8095 69.55.225.29 01061-0847 72°39'71"W 42°19'42"N -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'd second the recommendation of Smarty -- as Matthew implies, you can set it up to only allow a restricted set of tags in templates, and you can define what those tags are so that they are intuitive to your template-editing users. pb -- paul bissex, e-scribe.com -- database-driven web development 413.585.8095 69.55.225.29 01061-0847 72°39'71"W 42°19'42"N -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you're new to this and finding template engines confising, I'd urge you to start out by just doing "pure PHP" templating, i.e. what John is describing in the last sentence of his first paragraph. You get the structural benefits of templating (more readable program logic, more readable HTML) without having to learn any new syntax. In a nutshell, this means that you have a script that prepares data, and another (mostly HTML), included by the first, that presents it. The first, let's call it page.php, will be something like this: and page.tpl.php will be something like this: Current foo status: Page created on This is a minimal example, but even without further refinements this approach will create much more readable and maintainable code than the big-ball-o-mud interwoven-PHP-and-HTML style of development. The argument against template engines is well presented here: http://phppatterns.com/index.php/article/articleview/4/1/1/ Personally, I use Smarty for sites that need complex templating, and pure PHP templating for everything else. pb -- paul bissex, e-scribe.com -- database-driven web development 413.585.8095 69.55.225.29 01061-0847 72°39'71"W 42°19'42"N -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

How about array_filter()? From the docs: "If the callback function is
not supplied, array_filter() will remove all the entries of input
that are equal to FALSE."
$a = array ('a' => 'foo', 'b' => '', 'c' => null, 'd' => 99, 'e' => 0);
print_r (array_filter ($a));
// Output:
Array
(
[a] => foo
[d] => 99
)
As a previous poster noted, though, this will only work for you if "0"
and the empty string et al. are not significant in your application.

One more variant:
function a_an ($word)
{
return (stristr ("aeiouAEIOU", $word{0}) ? "an " : "a ") . $word;
}
echo "Member has " . a_an ($table['field']) . " who is...";

I think it's unlikely to change. PHP5 also works this way, though it
uses constructor methods named "__construct" (in addition to allowing
old-style constructors with the name of the class).
x = "data";
}
}
class Bar extends Foo
{
function __construct()
{
parent::__construct();
$this->y = "more data";
}
}
?>
FWIW Python also requires child classes to call parent constructors
manually. Not sure what the justification is for this design decision
is, though, in either language. Anybody?

Re: [PHP] Multipart Email Problem
I had the same problem a few months ago. I switched to Mail::mime
thinking that the problem was my homebrew code, but still the same
thing -- Outlook didn't recognize the message as multipart.
The fix was changing the newline sequence from "\r\n" to "\n".
The Mail::mime constructor allows you to change this value, so in my
code the change boiled down to:
$mime = new Mail_mime ("\n");
Hope this works for you.
