Hey folks,

I've been playing a lot with php recently, and I've really enjoyed it. I was looking around for a list of fun little projects to do in PHP, but I couldn't find one, so I decided to compile one myself, and maybe stick it up on a website somewhere. The eventual goal would be to help php programmers who are just getting started learn a little bit about programming.

So I'm looking for suggestions.
The first I came up with was simple. With graphics, sometimes I want to know what the ratio for scaling would be if I want to make an image smaller or larger, and the missing value. So I wrote a script that took the current height and width, and one of the new values that I wanted to scale to, and it provides the other.

So the first would be something like:
1) Write a script which will calculate the values to scale a graphic with.

Make sense? These ought to be relatively simple projects. Like processing files, performing calculations, etc. There are lots of programs that do little things like my example above, but it wasn't about needing it, it was about doing it to learn. Your help will be much appreciated.

I read your post three times and still can't figure it out... What exactly do you need help with? :>

Sorry.

I'm looking for ideas for little PHP scripting "challenges". "Write a script that does this..." Something that can be done in a day. A challange for novice PHP writers.

I'm definitely a PHP-neophyte, but for a client's website I wanted the stylesheets both to change with the seasons automatically - and be user-selectable. So I did some research and came up with this:
[php]
<?php
if(date("n") == 12) {
if(date("j") >= 22):
$DefStyle = 'vinter';
echo "<link rel=\"stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />
<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />";
else:
$DefStyle = 'host.css';
echo "<link rel=\"stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
endif;
}
if(date("n") >= 1 && date("n") <= 2) {
$DefStyle = 'vinter';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />";
}
if(date("n") == 3) {
if(date("j") <= 21):
$DefStyle = 'vinter';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />";
else:
$DefStyle = 'var';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
endif;
}
if(date("n") >=4 && date("n") <= 5) {
$DefStyle = 'var';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
}
if(date("n") == 6) {
if(date("j") <= 21):
$DefStyle = 'var';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
else:
$DefStyle = 'sommer';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />
<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
endif;
}
if(date("n") >= 7 && date("n") <= 8) {
$DefStyle = 'sommer';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />
<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
}
if(date("n") == 9) {
if(date("j") <= 21):
$DefStyle = 'sommer';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />
<link rel=\"alternate stylesheet\" href=\"host.css\" type=\"text/css\" title=\"host\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
else:
$DefStyle = 'host';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
endif;
}
if(date("n") >= 10 && date("n") <= 11) {
$DefStyle = 'host';
$AltStyles = "<link rel=\"alternate stylesheet\" href=\"sommer.css\" type=\"text/css\" title=\"sommer\" />
<link rel=\"alternate stylesheet\" href=\"var.css\" type=\"text/css\" title=\"var\" />
<link rel=\"alternate stylesheet\" href=\"vinter.css\" type=\"text/css\" title=\"vinter\" />";
}
?>

<link rel="stylesheet" type="text/css" media="screen" title="Brukerdefinert Stylesheet" href="<?php echo (!$sitestyle)?$DefStyle:$sitestyle ?>.css" />
<?php echo "$AltStyles" ?>[/php]

Don't know if this is the sort of things you are looking for, but I'd figure I'd post it anyway

SirCastor · Jan 29, 2006, 05:32 PM

Yes, definately the kind of thing I'm looking for. Except without the answer

2) Write a script that will swap out a style sheet depending on the time of year/season.

Thanks!

Aha. I also made a request for this (solution which can be found in web developer forum):

3) Write a php-menu that will know what page you are on and "grey" out the menu-item dynamically to avoid recursive links.
