Original image: x - 800 y - 600
New size: x1 -100 y1 - ?
y1 = 600*100/800 = 75
formula is: y1 = y*x1/x
the same if you want to find x1 when know y1.

hello!
i have a problem with a search-and-highlight script (see code below):
a search for "byt tes" matches entries that contain "bytes" but only
highlights "byt"*.
*) because after the first search term ("byt") is found the line is modified
into <span class="highlight">byt</span>es and therefore the secound search
term ("tes") can't be highlighted anymore.
1. general question
i'm not quite sure if a search like this should match entries that contain a
combination of both terms ("bytes").
of course, the word "bytes" contains both search terms - but on the other
hand, a search for "byt tes" indicates that i'm looking for TWO terms (and
also for TWO "t"s).
2. how to do it anyway?
do you have an idea how to accomplish that this kind of search
- either: does NOT display entries that match "bytes"
- or: displays entries that contain "bytes" and highlights "bytes"
(because both solutions seem to be somehow logical it may depend on the
easiness of creation and/or the speed of processing.)
thanks a lot for your effort!!

Thanks,
Is it better to use that function before the INSERT query and save it to the
database like that or use that nl2br() function while displaying the results
of the SELECT query,
Thanks agian.

Use it while displaying. You generally want to save the data in the
database exactly as it was entered. This will allow you to display it
back to the user for editing without them wondering what all the <br />
are in their sentences and also use it in other places, like mail or
files...

I believe, that alternatively, you can wrap the output within <pre></pre>
tags for the html out.

I think you can do this with an .htaccess file instead of the php.ini file

Something like this...
Add the following into a .htaccess file for your domain(s)
php_value SMTP smtp.yourhost.com

Hi there,
I'm sending emails to the subscribers of my site using mail() with a fourth
parameter to specify the From: and Reply-To: headers. They seem to be sent
correctly and the users may reply to them and I get the replies in the
mailbox identified by these headers.
The problem is some email addresses I'm sending email to are incorrect, and
I should be receiving the email notification saying that the email could not
be delivered. But I'm not receiving these messages in my mailbox.
Any ideas why this could be so?
Thanks a lot for any hints.
I'm sending mails with:
mail($to, $subject, $body, $from);
where $from = "<[EMAIL PROTECTED]>\nReply-To:
[EMAIL PROTECTED]: PHP/" . phpversion();
I've also tried using \r\n instead of \n

Send yourself an email using PHP and examine the Return-Path listed in the
source code. (The Return-Path is not the same as the From you're setting.)
If you're using a commercial host (shared hosting), then the Return-Path is
probably something like [EMAIL PROTECTED] My host provides
Horde for web-based email, and bounces go to the master user account.

Hi all,
I've just written this function:
$term='Michaelmas';
function f_week($w,$t)
{
$P=7*($w-1);
if( $t == 'Michaelmas'){
$D = 06;
$M = 10;
$Y = 2003;
} else {
$D = 12;
$M = 01;
$Y = 2004;
}
$week=date("d/m/Y", mktime(0,0,0,$D+$P,$M,$Y));
return $week;
}
?>
Michaelmas week 4 is <? echo f_week(4,$term) ?>
But the date it shows is '10/03/2005 ' rather than '03/10/2003'.
Suggestions please.

I have been searching for an answer to this for a couple of hours now and
cant find anything. I believe that there is a secure way of doing this but
I think my brain is having a momentary lapse...
I have these variables:
$eventid = "1";
$age = "15";
Is there a way to pass these variables to the next page so I can continue
using them without doing something like this:
<A HREF="test.php?eventid=1&age=15">
I would rather not have the variables be seen or known to the end user for
security reasons because they could change them in the URL. I know it has
something to do with $_GET and $_POST because I do have register_globals
set to OFF in my php file and I do not want to turn them on....
TIA
--- End Message ---

If you don't want them seen anywhere, then you've got to use
sessions.

Nabil,
That is one way but it means that Jay would have to use a form and not a
link.
You could set a cookie. That would work, but it relies on the user allowing
cookies.

That was my thought too, George. But if the user does not have cookies
enabled, then I believe, as Thomas pointed out, that a SESSION is the only
way to handle the variables. I have never done a "correct" session so I am
trying to learn how to do them without having a userid and password for
each user. I have played with sessions but I don't know if I am doing them
correctly or how to do sessions without authentication.

Jay,
I've never ventured into 'sessions' (not ones without drinks) but I've a
feeling that if the user has turned cookies off then sessions are out as
well as they require a cookie being stored on the user's machine.
Someone will surely correct me if I am wrong.
I went to the PHP conference in Frankfurt about 18 months ago and Rasmus was
talking about 'clean' URLs (ithout the 'query' string. I never did find out
how though?
Cheers

you can transfer the session-id (which is unique) through the url too.
but then its only the session-id and not the actual data and the session-id
can't be guessed that simple to reach another user's data.

I have been searching for an answer to this for a couple of hours now
and cant find anything. I believe that there is a secure way of doing
this but I think my brain is having a momentary lapse...
I have these variables:
$eventid = "1";
$age = "15";
Is there a way to pass these variables to the next page so I can
continue using them without doing something like this:
<A HREF="test.php?eventid=1&age=15">
I would rather not have the variables be seen or known to the end user
for security reasons because they could change them in the URL. I know
it has something to do with $_GET and $_POST because I do have
register_globals set to OFF in my php file and I do not want to turn
them on....
If you want to truly keep them away from the "client" then you need to
use sessions. Only the session ID is passed in a cookie or URL and your
data remains on the server. Using GET, POST, or COOKIE will allow the
user to edit this data.
If the user does not allow cookies, then you must pass the SESSION ID in
every URL that you want the session to persist.

If you really want to keep the values a secret, you will have to
substitute them with a reverable hash or some other method to keep prying
eyes away.

Yeah - just dumb!. I'd put my date vars into mktime in the european order.
Once I switched them it worked fine.

is this the correct way to register variables via a session?
[code]
session_start ();
$_SESSION['eventid'] = 'arma2';
print_r ($_SESSION);
echo "<P> $_SESSION";
[/code]
[result]
Array ( [eventid] => arma2 )
Array
[/result]
I apologize for the numerous questions, but I am trying to learn...If
anyone would like to help off-list, my ICQ is 38823829

PHP is server side. MySQL is server side. A client side browser (in this case
AOL), has no bearing on the output produced by PHP/MySQL.
You have been told to check your HTML output at least twice for
missing/unsupported tags.

Hi guys.
I want to call this generic echo function within a class, but have
trouble referencing the output function with $this-> .
Any suggestions? Maybe there is a better solution to this?
This is within a class:
[snip]
# generic WALK functions
function walkit($array)
{
array_walk($array,"$this->output"); //not
working
}
function output($item,$key)
{
echo "$key. $item<br />\n";
}

You want to apply a function that's wrapped in a class to a given array?
My first reaction is that your best approach is to invoke a function within
a class, without creating an instance of that class. See the :: operator.
The following code covers several ways of calling functions wrapped in
classes. You probably want the last two calls:
<?
/* Class A has method B */
class A {
function B ($s = "None") {
echo ("<p>input : $s</p>");
}
}
/* $C is an instance of A */
$C = new A ();
/* $D is an array of strings */
$D = array('item 1', 'item 2', 'item 3', 'item 4');
/* invoke A::B */
A::B ('call 1');
/* invoke $C->B */
$C->B ('call 2');
/* invoke A::B via call_user_func() */
call_user_func (array('A', 'B'), 'call 3');
/* invoke $C->B via call_user_func() */
call_user_func (array($C, 'B'), 'call 4');
/* invoke A::B via call_user_func_array() */
call_user_func_array (array('A', 'B'), array('call 5'));
/* invoke $C->B via call_user_func_array() */
call_user_func_array (array($C, 'B'), array('call 6'));
/* apply A::B to $D via array_walk() */
array_walk ($D, array('A', 'B'));
/* apply $C->B to $D via array_walk() */
array_walk ($D, array($C, 'B'));
?>

If the user has the credentials to access both directories, why not
let him be logged into both directories, provided he logs into both
separately?
You can confine cookie containing session id to the site _and_
directory user logged into so that you have have separate sessions
for both:
in your login routine in each directory:
session_set_cookie_params (0, dirname($_SERVER['SCRIPT_NAME']).'/');
session_start();
Now when user logs into different directory, php won't even know
about session cookie from other directory. This is my understanding,
anyway.

I think you want stripslashes().
