Ok here is how I solved it. When I have a url like www.xx.ccom/a/b/c for
example, what I do is
get an array of abc, ab, a
Then I run a union query for all three combinations. So basically select *
from {lookup_table} WHERE path = 'abc' UNION select ........
Then I just retrieve the first row mysql_fetch_object. That is what I need.
Thanks Anyways

That's the idea. You will have fun programming the AI and looking how
it "match" between others.
I'd like to see your game, do you still have it?

nice game tedd, I played it a lot of times and still can't beat it.
Also I have pass the link about 2 weeks ago in the office... and the
AI always wins
quite frustrating, but really entertained

I would love to see someone write an AI to beat my best skill level
that I could get into the AI. I can beat expert level now, every
time.. so I know there is more than I have captured so far in the
AI.. (thus the greyed-out option for skill level "Master") .. but as
Tedd alluded to in his reply to Ashley - having the skill is one
thing.. but capturing the skill in bytes is a feat, not for the meek
coder!
http://www.blisscode.com/BC_downloadables/Rama's%20Campaign%201.0.2%20-%20INSTALLER.ZIP
the game itself is like 1MB. The rest of those 14 MB's are for the
sounds (.wav) mostly.. and a few small graphics.
make sure your windows desktop screen resolution is set to the default
(96 d.p.i., IIRC) or else it is unplayable due to improper positioning
of controls. Also ignore the hokey opening .. I wrote it for the
members of the ashram where I was living at the time; just push any
key to get past the intro and then read the directions of how to play
in the help menu - the "?" icon in the sky on the top right.
Let me know how it goes!

That's what I had expected. ;-P
About eleven years ago, a co-worker and I each wanted the same day
off. I had seniority, but decided to play fair with him and give him
a shot. I told him that I could guarantee I could tell him the score
of a football game that night before the game started. If I was
wrong, he could have the day off AND I would give him my pay for the
day (we were medics for the state, so it wasn't a horrible chunk of
change). If I was right, I got the day off --- but to make sure it
was fair, we had to watch the game together that night, and he had to
pay for pizza.
When I got to his house, he ordered the pizza and asked if I was
ready to lose. I told him quite the contrary: before the game starts,
the score is a tie at zero-zero.
Being a good sport and admitting defeat, he let me have the day
off. Being as graceful as he was, I instead let him have the day
off.... and paid for the pizza.
A very "cheesy" story (yeah, that's right), but relevant. Seems
that now, in some places, trying to pull the same gag - even on a
friend - could get you two to the chest, single to the head. People
just don't have a sense of humor anymore....

Reminds me of many years ago when I was in New Orleans and a street
kid came up to me and said "I bet I know where you got them boots."
Considering that my boots were genuine elephant-skin made custom by a
boot maker in Las Vegas, I figured that the kid had mistaken the
maker for someone local. So I asked him "How much?" and he answered
"Five Bucks!"
I said "Okay, you got a bet." and the kid replied "You got them boots
on Bourbon Street." Considering that I was currently standing on
Bourbon street in the french Quarter, I saw how I had been tricked.
In any event, I paid the kid $5 and the next kid who asked me the
same question, I qualified the bet but had no takers.

pull out those restaurants names and reload the page ....

I always have doubts about comparison between boolean and integers.
Lets PHP shows hows is that he does.
The results where:
false < $int === true / $int !== 0
false <= $int === true
false > $int === false
false >= $int === false / $int !== 0
false == $int === false / $int !== 0
false === $int === false
false != $int === true / $int !== 0
false !== $int === true
true < $int === false
true <= $int === true / $int !== 0
true > $int === false / $int !== 0
true >= $int === true
true == $int === true / $int !== 0
true === $int === false
true != $int === false / $int !== 0
true !== $int === true
<?php # the script I used
function bol2string($boolean)
{
return $boolean ? 'true' : 'false';
}
$results = array();
foreach(array(false, true) as $boolean)
foreach(array('< ', '<= ', '> ', '>= ', '== ', '===', '!= ', '!==') as
$test)
for($i=-1; $i<1; ++$i)

Anton:
My way -- every time I open a database, I do so by including the
configuration.php file that holds the logon/password et other data to
connect with the database. When I'm done with what I want from the
database, I close it. I do not store anything in GLOBALS.

Sorry this is isn't good 'ninja' material.. but I gotta start where I
am.
this:
echo 'is set (EditExistingClient) ='. isset($EditExistingClient)."<br /
>\n";
is returning:
is set (EditExistingClient) =1<br />
but this, later down the page:
elseif ((isset($EditExistingClient)) || ($CreateClient)) //we just
created a client, OR edited a client
{
echo '<input name="EditExistingClient" type="submit" value="Edit This
Client">'."\n";
}
is not firing unless $CreateClient is set.
This, too, is not firing when I think it should:
elseif (($EditExistingClient) || ($CreateClient)) //we just created a
client, OR edited a client
{
echo '<input name="EditExistingClient" type="submit" value="Edit This
Client">'."\n";
}
what ridiculously simple thing am I missing?

I realize this is after the fact, but...
The above does not indicate WHAT it is set too. Just that it is set.
it could be set to /null/, FALSE, or 0 and they would all return false,
and fail, in your if condition later on.

The only possibility I can see is that $EditExistingClient is getting
modified between the echo and the first elseif statement.

Yes. 3 lashing. Thanks. I am not likely to neglect again

unfortunately I am still in over my head enough to have to ask..
Here is what I have now:

giving this error:
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL
result resource in /home/meee/public_html/somedir/test.php on line 62
I read about:
-mysql_fetch_assoc
-mysql_query
-SHOW TABLES
but do not see why this should be failing. Why isn't $result a '
valid MySQL result resource'?
Better late then never! :)
I played around with your code tonight and got this working on a test
server:
<?PHP
$db_billing = mysql_connect($DBHOST, $DBUSER, $DBPASS) or die("Could
not connect: " .mysql_error());
$db_selected = mysql_select_db($DB, $db_billing);
if(!$db_selected) {
die("Can't use database: " . mysql_error());
}
if (!$db_billing) { die('Could not connect: ' . mysql_error()); }
$sql = "SHOW TABLES";
$result = mysql_query($sql) or die("query failed:
" .mysql_error());
$resulttest = mysql_fetch_assoc($result);
foreach($resulttest as $k => $v) { //line 62
$ssql = "DESCRIBE ".mysql_real_escape_string($v);
$rresult = mysql_query($ssql);
echo "<b>".$k."</b>:<br />\n";
echo "<pre>\n";
print_r(mysql_fetch_assoc($rresult));
echo "</pre>\n";
echo "<br />\n";
}
?>
The only big difference from what you had is that I moved the
mysql_fetch_assoc($result); into a separate line rather then running
it from the foreach...
Let me know if that helps.

What you just offered just shows info about only the first column in
the table.
I got this working to show info about all the columns in the table:
$ssql = "DESCRIBE billing_table";
$rresult = mysql_query($ssql);
echo "<hr /><pre>\n";
while ($row = mysql_fetch_assoc($rresult)) {
print_r($row); //line 278

echo "</pre>\n";
echo "<hr />\n";
