[PHP] Trying to create a colortable - what am I missing here?
I've tried to make a color table, but I am missing something. not in the
color-table-code itself, but in somewhere else... I just can't find...
error_reporting is E_ALL, running it on my local server, the script has
512MB to spend, no errors occurs - just something, is wrong.
(4072 * 4072 ~= 255*255*255)
The problem is that the result image only contains all the blue(0,0,0 |
0,0,1 | 0,0,2 . 0,0,255) and the rest is black.
I've tried anything, did echo "X{$i % 4072}Y{LONG_Y_CODE}:{$r}-{$g}-{$b}\n";
All seems to be correct, what am I missing here? PHP 5.2.8
$im = imagecreate(4072, 4073);
$white = imagecolorallocate($im, 0, 0, 0);
$r = $g = $b = $i = 0;
$max = 255;
while ($r <= $max) {
while ($g <= $max) {
while ($b <= $max) {
$n = imagecolorallocate($im, $r, $g, $b);
imagesetpixel($im, ($i % 4072), (($i - ($i % 4072)) / 4072),
$n);
$i++;
$b++;
}
$b = 0;
$g++;
}
$g = 0;
$r++;
}
header("Content-Type: image/png");
imagepng($im);
imagedestroy($im);

Re: [PHP] php-general@lists.php.net, Tim-Hinnerk Heuer has invited you to open a Google mail account
LOL good points indeed! But I dont use other Google products that much. But yes I'm helping google in some way. One great satisfaction I have is I use Ubuntu with FireFox. :)
Re: [PHP] php-general@lists.php.net, Tim-Hinnerk Heuer has invited you to open a Google mail account
That's how you help information-monster-privacy-killing-companies to gain more control... You use GMail? ever visited blogspot? search on Google? Visit half of the leading sites of the world (since they have Google Analytics) or visit the other half that have Google Adsense or both of them? Maybe you use Google Chrome? Google Earth? Google Desktop? Android? Google _? You think that it? now it aims for you, the programmers. Use the "nice" Google AJAX API? so comfortable, lightweight Yes, now Google can collect MORE information. Yes? thank you by helping Google. if you use Google softwares, please click CTRL+ALT+DELETE, go to proccess, look for GoogleUpdate.exe and wonder why is it there? oh, now you remember? use Google Earth/Desktop/ ? Thank you for helping Google in another step for becoming an "information-monster". If anyone wants - I made a presentation about Privacy and how Google infiltrates your privacy. (I know someone will smile and say "but hey - you use Gmail". I'll just smile back and say that using gmail isn't "bad" - but using Google all the time IS bad). Watch how many large organizations have protested about Google "way" (of tracking you, as individiual, for over 18 months). Now someone again will "point" that "What do I mind if they are following me? I am not doing anything illegal". No, I am not saying the government will "use this information" - The FBI have asked all search engines to give him data about searches that might relate to criminal activities. they all gave. Except Google. What do they do with this information? Google Adsense, Analytics, News, Search, Images, API, Code. Blogspot, Adwords, should I continue this list of Google products that I am sure that each one of you was exposed to?

Re: [PHP] intval

Presumably you're doing this on the shell (versus in a web page). You
need to send the newline ("\n") character since most terminals buffer
the output until a newline character is encountered. If htis is a
webpage you are in for even more trouble since browser often won't
output anything until they receive at least X bytes (where X depends on
the browser).

Rob.

Maybe because you assigned values from $_POST to $value with the reference
operator?

[PHP] Something I don't understand about PHP classes
Ok, I suppose that this should be a very simple problem and probably the answer is obvious, but I really can't understand how the classes and the rest of the stuff works in PHP... Let's suppose that we have this piece of code: I have put an infinite loop in the class constructor just to introduce a problem that will halt the execution of the PHP code. Now, If I run this code I would expect that the PHP interpreter would print the "Hello world..." string, and then it should call the class constructor with the infinite loop inside of it. But that doesn't happen. Instead, the PHP interpreter enters IMMEDIATELY into an infinite loop, as if the variables were declared immediately and then the rest of the code is executed. Is it right?
