Well, you may not have the BCmath enabled, and this script will break if
bcmod isn't there, probably without you seeing an error message.
A tip for debugging image scripts - comment out the line like
header("Content-Type: image/jpeg");
and run the script again; if there is an error it will be displayed (error
settings permitting) whereas with the header in place, all you will get is
the broken image icon, most likely.

I can't see what your additional if statements give you that a straight
comparison wouldn't. Under normal circumstances, '' will sort exactly where
you want it, so this is an ideal case for a straight strcmp:
function cmpcountry($a, $b)
{
return strcmp($a['country'], $b['country']);
}
If, however, what you're trying to do is send all blank entries to the end, you
only need the tests for empty string:
function cmpcountry($a, $b)
{
$country1 = $a['country'];
$country2 = $b['country'];
if($country1 == '') return 1;
if($country2 == '') return -1;
return strcmp($country1, $country2);
}
Cheers!

Hi,
A pal of mine needed some help on his project, he is
using a "header" and "footer" file to "template" his
project... but its gotten a bit complicated as he has
a few dynamic parts in the header and footer files, so
I told him to go with a proper templating method of
templating the whole page rather than includ()ing the
top and bottom.
After having a better look at his scripts, I am just
not sure if something big (like SMARTY for instance)
would be good for him. He just needs maybe 5 template
pages, same pages, different color.
Searching google I see literally hundreds of
"templating solutions" can anyone recommend a simple
one or should I tell him to just use str_replace() for
tags like: {{menu_here}} {{header_here} etc?
Something like SMARTY would be like using a nuke to
kill a fly (IMHO) esp since this project will not
expand to anything much bigger or complicated.
Thanks!
Ryan

Ryan,
I would still recommend Smarty.
It can be as big as you like, but it can also be very simple to set up and
maintain. It has the features should your friend decide to expand his usage
in the future. If you opt now for something with limited features and later
decide to step beyond them, you'll be faced with making another major change
then.
Just my 2p worth.

This somewhat a "religious" issue for some, but my personal opinion is
that PHP is often very good at being a simple template system. Just
assign your variables beforehand, and display them with the <?= $var ?>
tag. (I do this with entire pages, split up into chunks for various
parts of content.)
I.e. template_head.php:
<?php
<html>
<head>
<title><?= $page_title ?>
<?php foreach ($css_files as $fn) { ?>
<style type="text/css">@import "<?= $fn ?>";</style>
<?php } /* end foreach ($js_files) */ ?>
</head>
<body>
?>
etc...
Then your page would look like:
<?php
/* Assign some variables */
...
include('template_head.php');
/* A little workhorse code, assign some more variables */
...
include('template_content1.php');
/* Assign even more variables */
...
include('template_foot.php');
After having a better look at his scripts, I am just
not sure if something big (like SMARTY for instance)

pages, same pages, different color.
Smarty is also excellent. (I still prefer pure PHP though. :-)

Why kill performance when you don't have to?

Ryan,
Don't forget, PHP itself is a templating language. Just do a standard page,
with includes for headers and footers, menus, and content.
If he wants to change colour, then load a different stylesheet for a given
page or content section.
This way he can use the tool that's right in front of him, he's not adding
another layer, he does not have to learn another "language" - the template
system written in PHP, and he hones his PHP skills.
Whew! Hope this is helpful.
Regards - Miles

I agree with Ryan - here is an example of a simple template I am using on a project at the moment. Stylesheets are used to control look and feel and the body tag is assigned a class so that different pages can use different layout elements. Hope this helps.

IMHO I would go with Smarty as it has excellent documentation and
would fit almost anything that the project would require. I also
think it would be a cleaner way of templating than using str_replace
() over and over again. For what it's worth, I use Smarty on almost
all of my projects, large and small. I find that once you learn it
you can use it to develop new sites rather quickly.
...and it's not like using a nuke to kill a fly - Smarty only loads
the files it needs as it needs them instead of loading everything -
so it's quite fast really.

I agree. I think this would be the best solution for a simple site. Good
point about honing PHP skillz.
As far as a CMS goes, textpattern is pretty dope. Simple to setup, free,
and it has a kick-butt template system.

Good day
I am busy working on a form using QuickForm.

On POST, you could redisplay the form in a "Frozen"
state. If the form is frozen, you display a separate
set of submit buttons and in checking to see if those
new buttons were clicked do you actually process the
form normally (access data store, etc).
This is just one of the many ways you can go about
achieving the same results.
thnx,

PHP List,
Very frequently I use mysql_fetch_row in a while statement to
while($variable = mysql_fetch_row($mysqlResult)){
echo $variable[text1];
echo $variable[text2];
}
Pretty standard.
But what do I do when I want to do the same kind of while loop not with
a MySQL result, but with just a regular array?
while (variable = ????($array)){
echo $variable[text1];
echo $variable[text2];
}
I've been up and down the manual, and looked at foreach statements and
functions like each(), but I can't seem to zero in on what I need.
Can anyone let me know what it is I'm missing?
Thank you for any advice.
