I understand what is happening here, however I really want something
simple like:
$link ="http://www.whataver.com/whateverpath/";;
$image = "123456";
new_image = munge($image);
new_link = $link . $new_image;
or maybe
new_link = munge($link . $image);
Which would encode the whole link.
Either way this is what would go into the email message we send out.
Thanks!

Encode in what way? What are you actually trying to stop people doing?
If all you're wanting to do is make sure people can't write a script
that simply requests n.jpg over and over again with an incrementing n
then all you need to do is obfuscate the filename when you store it on
your server. You then store that filename in the database alongside
the data it relates to.
$filename = sha1(time()).'.jpg';
Obviously that's just an example. You can generate the filename in any
way you choose as long as you check for duplicates before using it.
If that's not the reason please explain exactly what you're trying to
achieve rather than how you want to achieve it.

Hi All,

that the URL is
Domain.Com/Pix/123.jpg because the next person we take a picture
of may
be
123.jpg, so I am trying to munge/obfuscate the URL to make it

obvious.

That should have been:

Sorry to be such a newbie...
I basically would call this function lets say like:
munge( $url );
end in the end be returned the munged url, however, I don't
understand the
values you have like the readfile with that url -vs- failure?
I didn't munge... I provided code for a script that sends the
requested
image if it was requested with the appropriate key (presumably set
wherever the image was linked). If the key doesn't validate then
another
image is presented. It can say "bugger off", it can say "not found",
it
can say whatever you please. By placing the images outside the web
root
and using a script like this you are virtually guaranteed the visitor
can't just request images by making a lucky guess.
Let's say the above script was called: getUserImage.php
Then you might have the following in your HTML:
<img

Hi!
I have absolutely no clue if this will work. This has been typed
directly into my mail client, so no guarantees.
<?php
function toRGB($color) {
return array('r' => ($color >> 16) & 0xFF, 'g' => ($color >> 8) &
0xFF, 'b' => $color & 0xFF);
}
This function returns an array of red, green, and blue from an integer
like 0xFFFFFF.
function toColor($r, $g, $b) {
return $r * $g * $b;
}
This function is basically the opposite of the above. (the integer
value from red, green, and blue)
$image = 'smiley.png';
list($w, $h) = getimagesize($image);
$im = imagecreatefrompng($image);
for ($y = 0; $y < $h; $y++) {
for ($x = 0; $x < $w; $x++) {
Loop through the pixels.
extract(toRGB(imagecolorat($im, $x, $y)));
Take the values from the array return of toRGB so we can use $r, $g,
and $b instead of $array['r'], etc.
if ($r >= 0xCC && $g >= 0xCC && $b <= 0x33)
After some trial and error (looking at color charts), any red > CC,
green > CC, and blue < 33 is some shade of yellow.
imagesetpixel($im, $x, $y, toColor(($r + $g) / 2, 0, $b));
The expression inside toColor() is my attempt to calculate the correct
shade of red from the shade of yellow.
}
}
header('Content-type: image/png');
imagepng($im);
?>
:)
I don't understand half of that, can you explain what you did? (it
works) I was more trying to "fix" my problem then recoding the whole
thing though.
I hope that helps.

The thing is, it returns black. not red.
Oh. Replace the toColor function with the imagecolorallocate function
and add $im as the first parameter.

Thanks for the reply.
Can it be done by just using php + html or perl + html.
Also, May I know a beginners document to start working on html, php and
perl.
Thanks,

good points, thanks for the detailed info (not that I'd focus on it
while coding but its sooo interesting :) )

sure, these questions like 'echo or print' and 'single or double quotes'
and 'for or while' and so on should never be mentioned when talking
about real life code optimizing, as the difference they may make is so
minimal. talking about these is good only for satisfying some of my (and
maybe some other people's) curiosity about how php works internally :)

could you tell me more about this bytecode optimizer stuff? how does it
work, how much better/faster is it then APC/EAccelerator/etc?

yeah, that was morning time and I got mixed up a bit :)
Anyway, I had to admit that I was wrong in this matter, Rob Cummings has

from the print_r it looks like that you could access it like
$chpwrow[0]['loginPassword']

I have a linux based web app which prints an html screen of results.
My users really want Excel spreadsheets with the same results. There
is a PEAR application which does this, but from the PEAR description it
seems to be pretty buggy (65 open bugs, average days open 616 days) and
dated.
As long as your spreadsheets are simple without too much formatting etc., I
don't think you should worry too much about these bugs. I have used the
package in a variety of contexts without problems.
My spreadsheets will be somewhat simple. They will have multiple
workbooks and could be as large as 10000 rows spread out over 100
workbooks
I assume you mean multiple worksheets, not workbooks (AFAIK there can be
only one workbook per file)? I don't have any experience with a file that big.
You may also have a look at the PHPExcel package:

I'd like to grab the contents of left, right and main individually so
I can place them in separate form fields.
Any help greatly appreciated. I'm certain this is a cinch for people
who use regex often.
Thanks,
Jon

preg_match('/<OPEN_MAIN_COLUMN>(.*)<CLOSE_MAIN_COLUMN>/sUi', $string,
$matches);
echo $matches[1];
it's not very complicated, the only interesting bits are the s and U
modifiers at the end of the pattern. s makes the dot (.) to match
newlines too, so the matched text can be more than one line, the U makes
the engine 'ungreedy' which means that it stops after the first match.
this means that if you have a string like <open><close><open><close> and
match for <open>(.*)<close>, without the U modifier you would get the
part between the first <open> and the last <close>. with the modifier
you get the parts between any <open> and the next <close>

I'd like to grab the contents of left, right and main individually so
I can place them in separate form fields.
Any help greatly appreciated. I'm certain this is a cinch for people
who use regex often.
It's really not that hard if you use three separate expressions:
$left = preg_match('/<OPEN_LEFT_COLUMN>(.*)<CLOSE_LEFT_COLUMN>/is',
$text, $matches);
$right = preg_match('/<OPEN_RIGHT_COLUMN>(.*)<CLOSE_RIGHT_COLUMN>/is',
$text, $matches);
$main = preg_match('/<OPEN_MAIN_COLUMN>(.*)<CLOSE_MAIN_COLUMN>/is',
$text, $matches);
And then, IIRC, the content you're after will be in $matches[1].
