Re: [PHP] Reversing the Colour.
Assumptions:
- background colour is stored in $bgcol (ie 4592FF)
- chosen link colour is stored in $lncol (ie *same as above*)
- Finds half-way colour between $bgcol and $lncol (returns a RRGGBB in hex
as above)
Notes:
This is actually fairly simple Alexis.. Simply convert your hex vals to
something you can work with (ie dec) using hexdec() and then do some basic
maths to find the half way between each of the R G B vals and then finally
spitting out a hex value for the midway mark..
Implementation:
?php
/** Func: getMidColour **/
// Returns the midway value in HEX between the two DEC values $dec1, $dec2
function getMidColour($dec1,$dec2) {
return
dechex(abs(hexdec($dec1)-hexdec($dec2))/2+(hexdec($dec1)hexdec($dec2)?hexde
c($dec2):hexdec($dec1)));
}
// Parses 6char hex colour (RRGGBB) into 3 part RGB string and feeds into an
array
$bgcol_arr=split(,,preg_replace(([\d]{2})([\d]{2})([\d]{2}),$1,$2,$3,$
bgcol));
$lncol_arr=split(,,preg_replace(([\d]{2})([\d]{2})([\d]{2}),$1,$2,$3,$
lncol));
// We now can access the hex RGB values through the [0],[1],[2] elements of
these arrays..
// Using our custom function we can throw into our final array the actual 3
hex values
// desired which is the midpoint between $bgcol and $lncol
$midcol_arr=Array(getMidColour($bgcol_arr[0],$lncol_arr[0]),getMidColour($bg
col_arr[1],$lncol_arr[1]),getMidColour($bgcol_arr[2],$lncol_arr[2]));

Subject: [PHP] Reversing the Colour.
Hi,
I have a site whereby the user can select the colour of links for their
individual sections.
What I would like to do is to get the exact opposite colour of the one
that
they choose and use that in the 'hover over' option of the a tag.
The value for the colour is stored in hex.
To add to this, the user can also choose the background colour. I have
made
sure that they cannot have the same background colour as colour of the
link,
but obviously if the background colour is the exact opposite of the link
colour, then when they hover over the link, it would 'disappear'. In this
case I would like to choose HALFWAY between the two sets of colours. I
know
that this might not always produce the best colour combinations, but I'm
trying to get it so that the links always 'stand out'. I cannot let them
choose the colour of the 'Hover Over' option unfortunately.
Any suggestions as to how to achieve this, especially the calculations, or
for that matter improve upon it, would be most appreciated.

Alexis

Re: [PHP] Reversing the Colour.
Ok below is the fully tested and working code:
NOTE: . I have attached it too so wordwrapping email clients don't stuff the
lines up .. ;-)
This script will take in two 6character HTML hex colours (ie 44F0DD) and
return the midway colour between them (in Hex also)..
--
?php
//Example values..
$bgcol=39DFD9;
$lncol=F02816;
/** Func: getMidColour **/
// Returns the midway value in HEX between the two DEC values $dec1, $dec2
function getMidColour($dec1,$dec2) {
return
dechex(abs(hexdec($dec1)-hexdec($dec2))/2+(hexdec($dec1)hexdec($dec2)?hexde
c($dec2):hexdec($dec1)));
}
// Parses 6char hex colour (RRGGBB) into 3 part RGB string and feeds into an
array
$bgcol_arr=split(,,preg_replace(/(.{2})(.{2})(.{2})/,$1,$2,$3,$bgcol))
;
$lncol_arr=split(,,preg_replace(/(.{2})(.{2})(.{2})/,$1,$2,$3,$lncol))
;
// We now can access the hex RGB values through the [0],[1],[2] elements of
these arrays..
// Using our custom function we can throw into our final array the actual 3
hex values
// desired which is the midpoint between $bgcol and $lncol
$midcol_arr=Array(getMidColour($bgcol_arr[0],$lncol_arr[0]),getMidColour($bg
col_arr[1],$lncol_arr[1]),getMidColour($bgcol_arr[2],$lncol_arr[2]));
// Formats the array into a string and Upper cases it..
$midcol=strtoupper(join(,$midcol_arr));
?
-
You then have the $midcol var which holds a uppercase HTML hex colour string
which represents the midway colour between $bgcol and $lncol..
Finally.. :-p
Ok HIH

Re: [PHP] Multiple Domains in cookie?
GREAT Q! I have been trying to play with my cookies for a while now for this same reason.. And to no avail.. It seems due to the structure of them and as long as the client (browser) sticks to the specifications you can only access a cookie belonging to that same host.. For example, I am starting up a large network site base but I wanted all the sites even though they have their own unique domain to be able to have a global member login system.. Catch is.. The only way for them to be able to login to one site and then be able to freely go to another completely diff. site also on our network they would still be logged in and hence they have this main ONE account that allows them access to all our network sites.. So I studied the workings behind Terra Lycos and found their trick quite easily.. Since they have basically this same concept they too had to find a solution.. And their's is very close to mine :) I had thought.. since it's HOST specific. Not the full domain.. that means that cookies only differentiate between: aaa.com and bbb.com.. But not: one.aaa.com or two.aaa.com Therefore to create ONE cookie you set it's host for aaa.com and that way all your other site domains can be redirectors to the subdomain.. Ie.. if you have aaa.com as your main site and bbb.com and ccc.com just make those other two point to: bbb.aaa.com and ccc.aaa.com respectively.. Don't think it's unpro because that's exactly what Terra Lycos does.. For eg.. Checkout www.webmonkey.com (I'm sure many of you already know it) you soon see you'll be transported to: www.hotwired.lycos.com/webmonkey This is because not only is webmonkey part of Terra lycos.. It's also under HotWired.. Then I thought.. No way.. that can't be their trick surely?? Yep.. Checkout all their other sites.. More examples: www.angelfire.com goes to angelfire.lycos.com and tripod.com goes to tripod.lycos.com it seems this is the idea.. that way.. if they login.. just set some details (perhaps the SESSID so you can easily jsut reload the session on the other sites) on for example lycos.com as the domain and then all the subdomains can also use this freely.. Use your domains as redirectors and you get a sweet system.. :) HIH --oOo---oOo-- Julien Bonastre [The_RadiX] The-Spectrum Network CEO [EMAIL PROTECTED] www.the-spectrum.org --oOo---oOo-- - Original Message - From: Tony Harrison [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, September 28, 2002 7:25 PM Subject: [PHP] Multiple Domains in cookie?

Hey Julien!
Thanx for the code! Your posting from yesterday helped me out. Actually I
was on the right path all along but hadn't activated the GD-extension in my
php.ini and so I just got errors and grew _pretty_ annoyed by it. Then after
I got your message from yesterday giving med the same errors I realized that
there were somethin' cookin'. After activating the GD-extension and
restarted Apache your snippet worked fine and eventually mine too.
Thanx again for your effort, it would have been better though if we all had
sent this to the newsgroup. More people would have had a chance to see it
there...
Have fun

OMG..
This is the second question tonight I answer that I was just working on
today :-p
hah..
Ok.. simple.. here's my code I used today for
www.operation-scifi.com/lobby
Thing is.. It's about as understandable to other's as hieroglyphics..
Therefore.. a simple solution..
do this:
?
header(Content-type: image/jpeg);
$img=imagecreatefromxxx(../dir/img.ext); //where xxx = jpeg | png | gif
etc..
$img2=imagecreate(150,100);
$imgsize=getimagesize(../dir/img.ext);
imagecopyresized($img2,$img,0,0,0,0,150,100,$size[0],$size[1]);
imagexxx($img2);
?
Substitute the filepath etc.. and also the 150/100 dimension sizes..
xxx denotes the image type which depending on your GD version .. jpeg has
always been supported.. GIF has been removed as of 1.6 I think due to the
LZW compression patent by Unisys.. and now they have PNG which my site
uses
due to it's much better file format and flexibility..
Also BTW.. this script is designed to be a seperate file.. ie image.php
perhaps even do what I did and make the filename actually a $_GET param..
As in.. you call: ./image.php?im=whatever.jpg
and it generates a thumbnailed version..
if your using JPEG format you can also use this param in the
imagejpeg($img2); function:
imagejpeg($img2,,80); whereby the output quality is no 80%.. that means
lower qual thumbnail..
There is a lot of fun things that can be done just with the core graphics
module of PHP without GD.
but GD is soo great it can do much more exciting things..
Like for instance today I wanted to resize these big pics.. That's all
good.. But they are somewhat pixellised from the large downshrink. Now..
the
function imagecopyresample() would be great..
but's a GD2+ thing.. I don't use GD plus yet.. [downloading the bin as I
write this] but that's just one great func. taht allows for resize and
interpolation of near pixels (ie smoothing)..
w00tage eh??
Anyways.. enough said. rambling on now.. HIH

Subject: [PHP] Create Thumbnails from image
Hi,
I'm using a Win2k with php4.1 and I'd like to make some thumbnails from
pictures on my disk.
I've gotten the impression that it's possible, but I havent' found out
just how.
I've stumbled across the ImageCopyResized function but it requires a
imagehandle(?) to the file copied from. How do I get that? Is it the
right way to do this?
I guess I could use some picture manipulating program to do this, but
doing it the PHP way is nicer :)
TIA

Re: [PHP] Confused
well it depends how you want to go about it..
I have done something exactly like this, this morning.. :-p
Firstly.. you can use a normal SQL SELECT statement, but use GROUPing to
seperate the groups in this case and ORDER them alphabetically or
something..
Next.. You can do something like this:
?
$curgrp=;
$sql=mysql_query(SELECT groups.group_name, users.user_name FROM groups
INNER JOIN users ON groups.group_id=users.group_id GROUP BY
groups.group_name ORDER BY groups.group_name ASC, users.user_name
ASC,$DBH);
while($row=mysql_fetch_array($sql)) {
if($curgrp!=$row[group_name]) {
if(strlen($curgrp)0) echo /table;
$curgrp=$row[group_name];
echo table border=1 cellpadding=2 cellspacing=2trtd
colspan=2Group: b.$row[group_name]./b/td/tr;
}
echo trtdnbsp;nbsp;/tdtd.$row[user_name]./tdtr;
}
?
This HAS NOT been tested. but I have ran it through the inbuilt PHP
interpretor in my brain.. and passed it through the mySQL server also up in
my head.. and it seems OK..
In any case it was mainly to demonstrate the concept.. As you can see.. It
iterates through the result table which should look a little like this
(using your data supplied):
Blue,Tom
Blue,Nancy
Blue,Jim
Red,Bob
Red,Susan
Red,James
You get it?
HIH.. Please if you notice any bugs in the coding above.. point it out.. I
did it quite quickly and with very little checking as such or testing..
Good luck ;)
I could post what I used but that could get confusing.. :-p
Anyways.. Now I'm rambling.. ha. I'm off..

[PHP] 256colour PNG?? WHY?!
Hmm.. Interesting problem I seem to have stumbled upon I am running apache2.0.36 and php4.2.2 (i am using gd1.6.2) Now the catch is.. I just want to output a few diff image types directly to browser.. I can do JPEG's fine.. BMP's don't work because of using a older gdlib.. that's no big deal though.. i just wanted jpeg and hopefully PNG.. Thing is.. PNG's well.. it loads them fine.. but they end up 256colour palette in the browser.. it actually creates the new image from the original true colour (~24KB original) and instead spits out a 256colour ~4KB version.. since the palette's been reduced involuntarily this is not the desired effect.. I run the img resource through imagecolorstotal($img) to get the colour palette. sure enough.. it returns 256.. and yet i open the PNG in Photoshop and its a truecolour PNG and without discolouration.. It's definitely freaking me out since I have no idea why it's doing it. I started reading the docs' more closely to see if it was a known issue and that the png func's are supposed to return 256 colour images.. but to no avail.. Below is the code of the very simple (as can be seen) test php page: ? header(Content-type: image/png); //header(Content-Disposition: image; filename=test); $img=imagecreatefrompng(./news/n1d1.png); //imageinterlace($img,1); imagepng($img); ? As can be seen.. It's very simple.. hehe.. I was just using it to test the principle but even at these early stages the plan fell apart due to this wacky problem..

[PHP] PHP Execution Timer
I have seen it on many sites now and since I have been using PHP for so long and done a huge amount of coding with it I thought it would add a nice touch and it could be used for statistical purposes to assist me in database effeciency and so forth. The idea is a page execution timer.. or a database query timer.. basically it shows you just a time (usually in msecs) it took for the last command to be executed.. I have seen it used for queries and it returns the time it took.. And I am quite sure I've seen it used for actual page generation as well, whereby it says something like page generated in x.xxx secs I just want to know what function or module covers this feature.. If it is at all possible.. Thanks a million people! --oOo---oOo-- Julien Bonastre [The_RadiX] The-Spectrum Network CEO [EMAIL PROTECTED] www.the-spectrum.org --oOo---oOo--
