o` Thanks had the manual open but was looking near the bottom of the list of functions :s

January 2, 2009

Is it possible to check an array for a certain key rather than just the value.

E.g.

$array = array("test",50 => "tester");

if(in_array_key(50,$array))

echo "In array key";

That will return true because the key is named 50.

Any ideas?

One statement is a heck of a lot quicker and slicker =)

Speed difference is hardly noticeable if at all.

December 31, 2008

oopz, tbh ignore me i am very tired

December 31, 2008

Sorry my bad, should be file();

December 31, 2008

try changing the header to

header("Content-type: image/jpg");

and then

echo read_file("logo.jpg");

December 31, 2008

try

$sql = "SELECT * FROM `forum` WHERE `ParentID` = '1'";

December 31, 2008

If you change what i said, and you are showing all the code then you won't. It would show another error and stop the rest of the page running.

Show your current code.

December 31, 2008

$result=mysql_query($sql);

to

$result=mysql_query($sql) or die(mysql_error());

December 31, 2008

echo "<img src=\"logo.jpg\" border=\"0\" align=\"left\"></img>";

should be

echo "logo.jpg";

December 31, 2008

Your sql query is wrong, post it here or we can't help.

December 31, 2008

You need to do something like

<?php
$sql = mysql_query("SELECT posts FROM km_users WHERE playername = '$player'");
$sql = mysql_fetch_assoc($sql);
$posts = $sql['posts'];
$sql = mysql_query("UPDATE km_users SET posts = '".($posts + 1)."' WHERE playername = '$player'");
?>

December 31, 2008

Another problem, most of the tables in the query have the same column names

How do i properly reference them later on?

December 31, 2008

They are

I found the problem, in the big query using the joins not all the tables have anything in therefore it will return no results :s

December 31, 2008

Also to find out why you got that error and why it is good read through this sites security tutorial.

December 31, 2008

Can you use a query that uses an inner join and still loop through the rows.

Here is my attempt

<?php
$query = mysql_query("SELECT * FROM city ORDER BY city DESC");
while($row = mysql_fetch_assoc($query))
{
$sql = "
SELECT 
blackjack.max_bet,blackjack.owner_id,blackjack.city_id,
coinflip.max_bet,coinflip.owner_id,coinflip.city_id,
keno.max_bet,keno.owner_id,keno.city_id,
roulette.max_bet,roulette.owner_id,roulette.city_id,
slots.max_bet,slots.owner_id,slots.city_id,
war.max_bet,war.owner_id,war.city_id,
airport.crew_id,airport.id,
bulletfactory.crew_id,bulletfactory.price,bulletfactory.city_id,
ironworks.price,ironworks.crew_id,ironworks.city_id
FROM blackjack 
INNER JOIN coinflip ON coinflip.city_id = '".$row['id']."'
INNER JOIN keno ON keno.city_id = '".$row['id']."'
INNER JOIN roulette ON roulette.city_id = '".$row['id']."'
INNER JOIN war ON war.city_id = '".$row['id']."'
INNER JOIN slots ON slots.city_id = '".$row['id']."'
INNER JOIN bulletfactory ON bulletfactory.city_id = '".$row['id']."'
INNER JOIN airport ON airport.id = '".$row['id']."'
INNER JOIN ironworks ON ironworks.city_id = '".$row['id']."'
";
$sql = mysql_query($sql) or die(mysql_error());
while($rw = mysql_fetch_assoc($sql))
{
	print_r($rw);
}
}
?>

That prints nothing :s

December 29, 2008

December 29, 2008

It is finished, ignore the betting and the random names that appear.

Does it play ok for everyone, good points, bad points ?

December 29, 2008

Ok, then you could just do

This way it will only remove the word if it is on its own, this way you won't need a word list of allowed words

<?php
function SwearFilter($str)
{
  $swearwords = array("arse", "ass", "bitch");
  $replacement = "<span class='badwords'>[censored]</span>";

return str_ireplace(" ".$swearwords." ",$replacement,$str);
}

if (isset($_POST['submit'])) 
{
  $comment = $_POST['comment'];
  $comment = SwearFilter($comment);

  echo $comment;
}
?>

December 29, 2008

Can i ask why people like to solve simple problems with overcomplicated solutions ??

Mine works as good as any others and is shorter and simpler

December 29, 2008

You could just use str_ireplace();

Saves on all that code

e.g.

<?php
$bad_sentence = "bad bad words here";
$bad_words = array("bad");
echo str_ireplace($bad_words,"*****",$bad_sentence);
?>

A better example

<?php
function SwearFilter($str)
{
  $swearwords = array("arse", "ass", "bitch");
  $replacement = "<span class='badwords'>[censored]</span>";

return str_ireplace($swearwords,$replacement,$str);
}

if (isset($_POST['submit'])) 
{
  $comment = $_POST['comment'];
  $comment = SwearFilter($comment);

  echo $comment;
}
?>

Hey,

I am working on a small PHP blackjack and have just converted it to OOP.

I have cut out some of the script and kept just the main bits that you need to see.

Can anyone explain if i am using it correctly, and if not why not and how can i.

Thanks,

Now saves the card suite, but not what 10 is worth (either 10, king, queen or jack).

Any ideas?
