Switch that around. Interfaces cannot contain anything but function definitions.
Abstract classes can contain functions that'll be inherited.

Negative. It is perfectly fine to have code within an abstract
class. The documentation needs to get expanded a little bit to
define exactly how an for what use an abstract class can be used.
indeed.
Abstract classes can contain code - but abstract methods cannot.

You can't clear them; they're sent by the browser. It'll keep resending the same
values and you're script will authenticate. Only way to get rid of it is to close the
browser.
You could attempt to force the user to log with a known bad username and password by
using a link or header redirect.
header('Location: http://username:[EMAIL PROTECTED]');
Your login script should check for these known values and can react accordingly. You
know they are bad, so you can either present them with another dialog to log back in
or you can just not send any authentication headers and show them a "successfully
logged out" page.

I did one application where I used the PHP session table to tell who was
logged on, and which area of the application they were most recently in.
One of several flaws, was that I used Kill session to logoff, and that
caused them to disappear from any count of users logged on. Course, if they
had logged off, then they weren't logged on, but on the other side, users
were counted for every session they created, and closing and opening new
browser sessions caused them to be counted multiple times, and continue to
be counted until session "garbage cleanup" removed their session entries,
unless I used the session timestamp in my count algorithm. Session was
nice, because if a user was causing a problem, I could kill his session
entry, effectively logging him off, forcing him to logon again.

Thanks guys. Between your suggestions, I managed to come up with a

You can always return an array() something like this:
function fileUpload($file) {
$r = array(false,'');
switch($file['error']){
case UPLOAD_ERR_INI_SIZE:
$r[1] = 'The uploaded file exceeds the upload_max_filesize
directive in php.ini.';
break;
case UPLOAD_ERR_FORM_SIZE:
$r[1] = 'The uploaded file exceeds the MAX_FILE_SIZE directive
that was specified in the HTML form.';
break;
case UPLOAD_ERR_PARTIAL:
$r[1] = 'The uploaded file was only partially uploaded.';
break;
case UPLOAD_ERR_NO_FILE:
$r[1] = 'No file was uploaded';
break;
default:
if ($file['type'] == "image/gif" || $file['type'] ==
"image/pjpeg"){
if (@copy ($file['tmp_name'], "images/" .
$file['name']))
$r[0] = true;
else
$r[1] = 'Could not copy the file.';
}else {
$r[1] = 'The uploaded file is not the right type.';
}
break;
}
return $r;
}
list ($status, $error) = fileUpload($file);

Because === and !== check the type as well. Of you set $string =
'blah' you'll still get the same result.
If you were using != and == both would print.
strpos() returns an int, so comparing it to false with === is always
false. The same would be true for true.

That's half right. strpos actually *can* return false as opposed to 0, so
checking doing the === check might be necessary for your application.
<?php
$string = 'blah';
if (strpos($string, 'not in the original $string') === false){
echo 'False check succeeded - not in $string.';
}
if (strpos($string, $string) === true) {
echo 'True check succeeded - in string';

Because strpos returns the integer offset of the found substring, or FALSE
if not found; it *never* returns TRUE. (You need the !== test because
strpos() can return an offset of zero, which would be ==FALSE but not
===FALSE.)

Yes you can.
I'm not going to give you the code, but a pointer to solving problems
yourself.
Just break the problem down to its component parts, and resolve each one as
you go. For instance, you need to define an option as selected - first
figure out how to do that (it's a HTML problem).
Then you only want to define an option as selected if certain conditions are
met, so test for the conditions and act accordingly.

To Open a New Window you can use javascript
window.open or just set target="_blank" in your anchor
tag (<a>).
But you may need to adjust the properties of new
windows like status bar, toolbar, width, height; for
this you can use java script.

Yeah, but sometimes you want the print version to be more nifty, like
have all the pages in an article instead of just the current page.
That calls for some server-side work AND a specific print-only CSS.

Now what I want to do is read this file, but only say read 5 songs
worth, then I would place the PHP code in (another table) and display
the next 5 songs and so on.... This just allows for a more flexible
layout in the final presentation. the way I am having the text files
written, there is no way to get it to produce seperate text files -
otherwise this would be easy to do....
Is this possible?
Yes, possible. Worth the time? No. Can you put all that info in a

into a database. Problem is, if someone hits reload on their browser, I
get the same data re-inserted again. Reload the page four times, and I
will get four records with the same data inserted. How can I avoid
this? I'd like to silently either discard the information after it's
been inserted, or silently prevent it from being re-inserted again.

This is what I call the BRS (Browser Reload Syndrome: the tendency
of idiodity users insisting on reloading a page unnecessarily.)
The basic solution with this problem is:
1. generate some sort unique id on original form
2. ensure unique id has not been entered when posted.
In your case, paypal should be returing to you some sort of
transaction Id, 'txn_id' iirc. So step 1 isn't needed.
What you need to do is before you insert the data that has been
posted to your script, is to ensure that that 'txn_id' has not been
entered already into the database.

1. Receive PayPal data in your script.
2. Process it (stick into database).
3. Redirect to another script and forward any data you want displayed.
4. Have the 2nd script show whatever confirmation message you want.
The user can now reload all he wants, he gets just the 2nd script
which doesn't do anything but display the same message over and over.
ATTENTION: if you receive the PayPal data by POST be sure to redirect
using "303 See Other", which will "deactivate" the POST and force the
redirect to use GET. Of course, forwarding any data to the 2nd script
should be done as GET parameters.
Or, even better, just forward the 2nd script the database ID of the
data you just recorded and if it needs to display anything it can get
it from there.

Linux. PHP5.
Why does this fail when using an array element, but using a variable will
work? Why should PHP care what the variable is I'm trying to store into?
list($bar['CompanyCode'], $CompanyDB) = mysql_fetch_row($sth);
But this works:
list($foo, $CompanyDB) = SQL_ROW($sth);
And of course I'd have the extra...
$foo = $bar['CompanyCode'];

Because list() is a language construct, not a function. It assumes
what you give it is a normal variable, it doesn't understand arrays.
Better IMHO to use $row = mysql_fetch_assoc() and access the array it
returns directly.

check the manual for list. It mentions using only numerical array
indices for list. There is a warning on it even i beleive.

Why MRTG _and_ PHP? AFAIK MRTG produces its own HTML and images.
You can either use MRTG with whatever data (webstats) you collected
or you can use PHP+MySQL for that and generate graphs from PHP.
There must be PHP solutions to generating graphs out there, or you
can write your own.

Curt, thank you. I like Mantis, too but wanted to check the php thing. I was
confused there is no reference to it anywhere, as it's used by e.g. MySQL,
too.
Thanks,

Hi,
I am a newer of this list, nice to meet every body here:)
I am wandering about using apache1 or apache2 with php, and i hope i can
get some advics here ;)
I use ./configure --help and it says:
--with-apxs2[=FILE] EXPERIMENTAL: Build shared Apache 2.0 module.
FILE is the optional
pathname to the Apache apxs tool; defaults to apxs.
and I read these from php manual:
http://www.php.net/manual/en/install.apache2.php
it says:
Warning
Do not use Apache 2.0 and PHP in a production environment neither on Unix nor on
Windows.
I don't konw which version of apache works with php better:)

I did not test it:)
function isValid($strData, $bIncludeAlpha=false, $bIncludeNumber=false)
{
switch(true) {
case $bIncludeAlpha && !$bIncludeNumber:
$ptr = "/^[a-zA-Z]+/";
break;
case !$bIncludeAlpha && $bIncludeNumber:
$ptr = "/^[0-9]+/";
break;
case $bIncludeAlpha && $bIncludeNumber:
$ptr = "/^[a-zA-Z0-9]+/";
break;
}
return preg_match($ptr, $strData);
}

Something like:
function isValid($strData, $blIncludeAlpha, $blIncludeNumeric)
{
$strPattern = "/^[;
if ($blIncludeAlpha):
$strPattern .= "a-zA-Z";
endif;
if ($blIncludeNumeric):
$strPattern .= "0-9";
endif;
$strPattern .= "]$/";
return preg_match($strPattern, $strData);
}
Cheers!

Where are you doing the test for it -- in the same script, or in a
subsequent one? If the former, then I'm confused; if the latter, then this
is expected behaviour (explanation on request ;).
