PHP - Php Count - Instances Of A Certain Result - Game Scores

 $result = mysql_query("SELECT *  FROM `friend_system` WHERE `friend_system_accepter` = '$myusername' ");
echo mysql_num_rows($result);

This displays the total rows in the table.

$result = mysql_query("SELECT COUNT(friend_system_accepter)  FROM `friend_system` WHERE `friend_system_accepter` = '$myusername' ");
echo mysql_num_rows($result);

This displays '1', which is incorrect.   I want to echo out the number of rows where 'friend_system_accepter' = $myusername   Thanks

Hello, I am building an online game(users make a character and move on a map and so on...)   All user data is stored in a mySQL database and I want the users to interact in real-time, but there can be a 1-3 second delay between the communication, but not exceed 3 seconds even if 500 players are playing at the same time.   But for the purpose of the question let's say the users can only chat between one another, if I'll have a solution for that then I can use the same method for more parts of the game.   I can't use websockets because my webhost doesn't support it( I don't want to use pusher.com).   I know I can make real-time apps with ajax long polling, but I think that with 500 players playing at the same time it's not the best solution.   So, finally: How can I make user interaction as close as possible to a real-time game? (Without too much load on the hosting server)   (I am sorry if some of my terms are not correct - I am just getting back to coding after a long time...)

Hello, I have what I hope to be a very simple question..

I have built a game in flash and for my high score table I simply want to request the high scores in reverse.. i.e the lowest score first..

here is my php.. please help, thanks in advance !! :-

<?php
include("sqldialog.php");

$table = $_POST['tab'];


$recept = SelectDatas($table, "name, score, dategame", "id > 0", "score desc");
if ($recept) {
   $i = 0;
   foreach ($recept as $rec) {
      $i++;
      if ($i==1) {
      $result .= "pseudo$i=".$rec['name']."&score$i=".$rec['score']."&dategame$i=".$rec['dategame'];

Hey,

I've been working on a script to match playing card hands in a poker game against the river to return what the hand the user has and who won against other players.

The problem is how do i approach an algorithm to do this in the first place.

Cards are stored and structured by 2 characters seperated by a full stop.

Example - 2 of diamonds and 3 of clubs is:
D.2,C.3

now imagine a line of 5 cards (the river) and im trying to work out what they have and return the answer such as:

2 pairs or royal flush etc

I so far decided my easiest way is to explode on the comma to get each card - then explode a second time on the full stop to get the suit and value into different variables.

How ever - after that point im lost how i can do this up against the river to check what hand the user has.

Any one got any tips on the best approach ?

Hi all

I have some code that displays the high scores for a game.

Unfortunately, if a user has more than 1 high score in the table all scores for that user are displayed.

I would like to only display the highest score per user.

My Current Code
Code: [Select]
$sql_query = sprintf("SELECT * FROM `highscores` WHERE `gameID` = '106'  ORDER BY `score` DESC");
//store the SQL query in the result variable
$result = mysql_query($sql_query);
if(mysql_num_rows($result))
{
//output as long as there are still available fields
while($row = mysql_fetch_row($result))
{
echo ("$row[3] Scored :$row[5] <br>");
}
}
//if no fields exist
else
{
echo "no values in the database";
}
mysql_close($con);
OutPut

User1       300
User1       298
User 2      297
User1       296
User3       295
User2       290


I would like the output to be

User1       300
User 2      297
User3       295

Any help is much appreciated

Why am I getting this error when there are 3 Fields with 3 values?

Column count doesn't match value count at row 1

Code: [Select]
$sql5="INSERT INTO participants (participant_name, team_no, sport)
VALUES ('".implode("','$_POST[team]'),('",$_POST['participant_name'])."','$_POST[team]','$sport')";

I am using mod_php with Apache/2.4.6 (CentOS).  I currently do not have multiple versions of PHP running on my server, but wish to do so now.

Will I need to use php-fpm?  Even if multiple instances can be accomplished with mod_php, is it typically preferred to use php-fpm?

Any unusual gotcha's that I should be aware of?

Will I need to uninstall mod_php before installing php-fpm?

I previously used remi-php73 repo.  Better to install from source?

Thanks

I have a loop creating a block_vars array for displaying records from a database. (In this case auction listings).
The following code creates this array:

// get random selection of 6 items for home page display
$query = "SELECT id, title, current_bid, pict_url, ends, num_bids, minimum_bid, bn_only, buy_now, subtitle, starts, ends, reserve_price
        FROM " . $DBPrefix . "auctions
        WHERE closed = 0 AND suspended = 0 AND starts <= " . $NOW . "
        ORDER BY RAND() DESC LIMIT 6";
$res = mysql_query($query);
$system->check_mysql($res, $query, __LINE__, __FILE__);
   $showendtime = false;
   $has_ended = false;
      
$k = 0;
while($row = mysql_fetch_assoc($res))
{
   $ends = $row['ends'];
   $difference = $ends - time();
   if ($difference > 0)
   {
      $ends_string = FormatTimeLeft($difference);
   }
   else
   {
      $ends_string = $MSG['911'];
   }
   
   $high_bid = ($row['num_bids'] == 0) ? $row['minimum_bid'] : $row['current_bid'];
   $high_bid = ($row['bn_only'] == 'y') ? $row['buy_now'] : $high_bid;
   
   //determine whether the auction has a Buy Now price, show if appropriate.
   if($row['buy_now'] == '0.0000') {
   $bnamount = "";
   } else {
   $bnamount = "<a href='" . $system->SETTINGS['siteurl'] . "buy_now.php?id=" . $row['id'] ."'>$" . substr($row['buy_now'], 0, -2) . "<br />" . "Buy Now</a>";
   }
      
   //determine if the auction has a reserve set and if it has been met. display appropriate symbol
   if($row['reserve_price'] == '0.0000' && $row['bn_only'] == 'n' && ($row['current_bid'] < $row['minimum_bid'])) {
      $flag = '<img src="images/noreserve.gif" alt="No Reserve">';
      $flagdesc = " No Reserve!";
      $bnonly = "Current Bid<br />";
      } else {
         if($row['current_bid'] >= $row['reserve_price']) {
         $flag = '<img src="images/reservemet.gif" alt="Reserve Met">';
         $flagdesc = " Reserve Met!";
         $bnonly = "Current Bid<br />";
         } else {
         $flag = '<img src="images/noflag.gif">';
         $flagdesc = "";
         $bnonly = "Current Bid<br />";
         }
      }
   if($row['reserve_price'] == '0.0000' && $row['bn_only'] == 'y') {

      $bnonly = "Asking Price ";
      $bnamount = "";   
      }

   $template->assign_block_vars('randomitems', array(
         'ID' => $row['id'],
         'BID' => $bnonly . "$" . substr($high_bid, 0, -2),
         'IMAGE' => (!empty($row['pict_url'])) ? 'getthumb.php?w=' . $system->SETTINGS['thumb_show'] . '&fromfile=' . $uploaded_path . $row['id'] . '/' . $row['pict_url'] : 'images/email_alerts/default_item_img.jpg',
         'TITLE' => $row['title'],
         'BUY_NOW' => $bnamount,
         'SUBTITLE' => $row['subtitle'],
         'TIMELEFT' => $ends_string,
         'NUMBIDS' => $row['num_bids'],
         'FLAG' => $flag,
         'FLAGDESC' => $flagdesc
         ));
   $k++;
   
}

Pretty straightforward. You will see I have a TIMELEFT value which will show on my home page as no.days, no.hours, no.mins until it closes etc.
Here is the html in the tpl file:
Code: [Select]
<!-- BEGIN randomitems -->
            <div style="float:left;display:block;width:99%;border-bottom:#CCCCCC 1px solid;padding:2px;">
                <div style="display:block;">
                 <table width="100%">
                  <tr>
          <td align="center" style="vertical-align:middle;width:120px" >
       <a href="{SITEURL}item.php?id={randomitems.ID}"><img src="{randomitems.IMAGE}" alt="{randomitems.TITLE}" style="border: none;width:120px"></a>
       </td>
       <td align="left" width="40%">
        <table style="width:100%; vertical-align:middle; margin:0 auto">
         <tr>
          <td><a id="itemdesc" href="{SITEURL}item.php?id={randomitems.ID}">{randomitems.TITLE}</a><br />
                      {randomitems.SUBTITLE}</td>
                     </tr>
                     <tr>
                      <td id="closes">Closes in:{randomitems.TIMELEFT}</td>
                     </tr>
                     <tr>
                      <td>{randomitems.FLAG}{randomitems.FLAGDESC}</td>
                     </tr>
                    </table>
       </td>
       <td id="buynow" align="center" width="15%">
       {randomitems.BUY_NOW}
       </td>
       <td id="currentbid" align="center" width="25%">
       {randomitems.BID}
       </td>
      </tr>
     </table>
                </div>
            </div>
<!-- END randomitems -->

This works quite nicely for me.
 
What I want, and cannot manage thus far is to have the TIMELEFT value count down.
 
The closest I have come is using a function like this:
Code: [Select]

<script type="text/javascript">
$(document).ready(function() {
 var currenttime = '{randomitems.TIMELEFT}';
 function padlength(what)
 {
  var output=(what.toString().length == 1)? '0' + what : what;
  return output;
 }
 function displaytime()
 {
  currenttime -= 1;
  if (currenttime > 0){
   var hours = Math.floor(currenttime / 3600);
   var mins = Math.floor((currenttime - (hours * 3600)) / 60);
   var secs = Math.floor(currenttime - (hours * 3600) - (mins * 60));
   var timestring = padlength(hours) + ':' + padlength(mins) + ':' + padlength(secs);
   $("#ending_counter").html(timestring);
   setTimeout(displaytime, 1000);
  } else {
   $("#ending_counter").html('<span class="errfont">{L_911}</span>');
  }
 }
 setTimeout(displaytime, 1000);
});
</script>

This code is placed in the tpl file and I simply give an html element the appropriate ID. The problem with this is that it would only show a countdown timer for the first item returned, which is no good as there are always six items returned.
 
Can anyone offer a suggestion on how I could go about this? I can PM anyone with suggestions with a link to my development site so you know what I am raving about.

I am really lost here with this date issue of mine. The below code is the last part of a query:
Code: [Select]
$defendercheck_3 = $row_checkifattacked3['atdate'];
$defendercheck1_3 = strtotime("$defendercheck_3");
$defendercheck2_3 = date("D", $defendercheck1_3);
The query does not return any results as expected, but when echoing the various steps I get following:

echo "$defendercheck3"; = nothing (as expected)

echo "$defendercheck1_3"; = nothing (as expected)

echo "$defendercheck2_3"; =  result! (NOT expected)

why does it return anything on "date("D", $defendercheck1_3)" when "$defendercheck1_3" is blank?

Anyone can help me?

<?php
$tbl_name="menu";
$kategorije = mysql_query("SELECT * FROM $tbl_name WHERE Left(menu_name, 1) BETWEEN 'A' AND 'M' ORDER BY menu_name ASC");
if (!$kategorije) {
die("Database query failed: " . mysql_error());
}

while ($row=mysql_fetch_array( $kategorije )) {
echo "<div id=lista-header><h4>{$row["menu_name"]}</h4></div>";
$id_sub=$row['id_menu'];
$podkategorije = mysql_query("SELECT * FROM submenu WHERE id_menu=$id_sub ORDER BY sub_name ASC", $connection);
if (!$podkategorije) {
die("Database query failed: " . mysql_error());
}
echo "<ul class=\"pod\">";
while ($pod=mysql_fetch_array( $podkategorije )) {
echo "<li><a href=index.php?=podkate?".$pod["id_sub"]." class=black>{$pod["sub_name"]}</a><hr size=1 align=left width=100px color=#cccccc></li>";
}
echo "</ul>";
}


?>

In this way, I get list with categories and hes subcategories. How to count how many subcategories have each categories, and count how many articles have each categories?

Example (I wanna get this kind of look):

Categories name (3)
subcategoriesname (2)
subcategoriesname (4)
subcategoriesname (7)

Categories name (5)
subcategoriesname (1)
subcategoriesname (14)
subcategoriesname (9)
subcategoriesname (2)
subcategoriesname (


Categories name (2)
subcategoriesname (28)
subcategoriesname (17)

Where the numbers represent how many categories and sub-items have articles
