Does no one know what I am talking about -.-

What is the following in bold called? I do know what it does, I just do not know the name of it. switch($command[$i]{0}) {

I got the problem fixed. I had to do the image tag like you said. Thanks for your help.

The subject says it all. I'm trying to build a tiled map.

Hi. I'm working on a project that involves taking two or more images and placing them on top of each other. I remember there used to be a Tutorial on the web that used brian griffin as an example. I am looking and looking and I cannot find anything about it, unless I am searching incorrectly. Any help would suffice Thanks in advance.

Yup... Looks like I do need to go to bed... Thanks a lot.

I've been trying to figure this error out for a while now. $sql = "select * inventory where pid=".$settings['user']['stats']['id']." AND id=".$itemId; $result = $db->db_query($sql); $item = $db->db_fetch_array($result); I use have been doing all of my queries like this. But now I get an error like this. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'inventory where pid=1 AND id=1' at line 1 Please help me figure it out.

Hello everyone, i'm playing with the PHP GD library, just to keep myself practicing. In the code I am grabbing the coords from a DB and putting them in an array. The code works, but I don't think its the best way of doing it... it just doesn't look right. I'm not really used to making arrays out of loops, but this is my code; $place = 0; $pixelQ = $class->query("select * from pixelCoords where owner='1'"); while($pixelF = $class->fetch()) { $corners[$place+1] = array('x' => $pixelF['x'], 'y' => $pixelF['y']); $place++; } This is a small part of the script, of me calling the array to be used; imagesetpixel($gd, round($x),round($y), $red); $a = rand(1, $place); $x = ($x + $corners[$a]['x']) / 2; $y = ($y + $corners[$a]['y']) / 2;

Ok, I have a basic idea of what I should do for this. But I also do not believe it is an efficient way of doing this. My basic idea: Set all tiles to unsigned Place a few random land seeds Check all adjacent tiles to see if unsigned if unsigned, give it a property (land water whatever) (70% chance to be water, if land make unsigned tiles around it land) Like I said... basic. I just don't know how i would make the land stop growing after it starts... I don't know how I would make the land look more natural (not so square)... and shore lines I think are going to be hard. I don't want the code for a random generator... Just help understanding how this process would be completed (a push in the right directions) Thank you for any and all help from everyone in advance; drseuss

All is well now. Thanks a lot for you help. Now I continue testing.

I didn't change a lot. And it does not error out. <?PHP error_reporting(E_ALL); include 'lib/database.class.php'; $db = new Database(); $query = $db->query('select * from accounts'); while ($a = $db->fetch($query)){ echo $a['id'].$a['username']."<br />".$a['password']; } ?>

Well it doesn't loop non-stop anymore. But it still wont display results. Thanks for your help, I guess I didn't fully understand how the loop works. Lol

Yea thats the credentials I use on my home comp (xxamp haha). I'd never give my info out lol I understand where you are coming from, but I cannot think of how to make the $this->query() run only once while the results keep going.

Hello, I am new to OOP. I am trying to make a Database Class, which was going well up to the testing period. When I run the test, the script runs without parse errors or anything, but the output never stops, kind of like the script is in an infinite loop. Oh and if you plan to bitch and moan about me being new to OOP coding, have at it. Just remember that it shows how immature a person you are. Thank you in advanced. database.class.php <?PHP class Database { var $host; var $user; var $pass; var $selectDb; var $connection; var $Db; var $query; var $error; function __construct() { $this->host = 'localhost'; $this->user = 'dwsonet'; $this->pass = 'p1a2s3s4'; $this->selectDb = 'dwsonet_game'; $this->connect(); } function connect() { $this->connection = mysql_connect($this->host, $this->user, $this->pass); if(!$this->connection) { $this->error = mysql_error(); die('Can not continue'); } $this->Db = mysql_select_db($this->selectDb,$this->connection); if(!$this->Db) { $this->error = mysql_error(); die('Can not continue'); } } function query($sql) { $this->query = mysql_query($sql)or die(mysql_error()); return $this->query; } function fetch() { return mysql_fetch_array($this->query)or die(mysql_error()); } } test.php (I made it simple to show how I am using it. Please correct me if I am wrong) <?PHP error_reporting(E_ALL); include 'lib/database.class.php'; $db = new Database(); $query = 'select * from accounts'; while ($a = $db->fetch($db->query($query))){ echo $a['username']."<br />".$a['password']; } ?>
