PHP - High Scores Table
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']; } else { $result .= "&pseudo$i=".$rec['name']."&score$i=".$rec['score']."&dategame$i=".$rec['dategame']; } } echo $result; } else { echo "BAD, $pseudo, $score, $dategame,$ipclient"; } ?> Similar TutorialsHi 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 HOw to get the AVERAGE of my entire database? $query = "SELECT ROUND(AVG(scores)) FROM table"; Thanks! Bickey 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 ? This topic has been moved to Other. http://www.phpfreaks.com/forums/index.php?topic=357168.0 PHP/MYSQL - - - Thank you in advance for any help. Quick question. I am calc'ing whether each line db output is a win/loss/tie below. Outputting $res in each line. Is there a simple way to COUNT the number of instances where $ res = "win" or loss or tie? I'd like to put an "overall" record at the top of the output. For example, for a given query, this chosen team's record is x WINS, Y Losses, Z TIES. Win/Loss/Tie is NOT a field in the db table. I know how to pull the total # of records pulled, but not this. Example User pulled a certain team to see game scores. 7 - 3 - 2 is their record. is what i'm trying to figure out Game Result Score Score opp Date game10 WIN * 7 2 blah game11 LOSS* 2 3 .... .... Code: [Select] //winloss begin works * above is a result of this code if ($row['sch_uba_score'] > $row['sch_opp_score']) $res = 'Win'; elseif ($row['sch_uba_score'] < $row['sch_opp_score']) $res = 'Loss'; else $res = 'Tie'; // winloss end works I have just did this php code for the high-low game but the $tries variable always goes down to 0 when I refresh..Can someone help me to return the $tries to browser with the url? Thank you

<?php function High_Low($guess){
ok so i want to order by high to low on the field price but i don't know how to do this. i can order low to high by using ORDER BY `Price` ASC but how can i order high to low? I try to get a high score system to work. The problem is to write data to the txt file: The file adder.php contains: <?php if(array_key_exists('name',$_GET)==true and array_key_exists('score',$_GET)==true) { $name=$_GET['name']; $score=$_GET['score']; $file=fopen('highscore.txt','a'); fwrite($file,$name.';'.$score.';'); fclose($file); } header("Location: index.php"); // Replace index.php with the name (and, if not in the same folder, path) // of the page that will display the scores (see below) ?> I use this website: http://members.multimania.nl, so it looks like http://members.multimania.nl/mine/adder.php?name=winner&score=99 What am I doing wrong? I successfully load a page by simple_html_dom.php (developed in simplehtmldom.sourceforge.net) as $html = file_get_html('externalpage'); But sometimes this make a high load on CPU and the page does not load for a long time (probably due to the external site server). How can I skip the process when it is not normal to avoid high CPU usage? I think I've coded myself into a corner. I have numerous items entered with measurement extremes - highest and lowest. Now I want somebody to be able to search for an item that could match a specific length. So I could have several items that are entered into a database like this: Code: [Select] item_id | length | high_low_param -----------+-----------+---------------------- 1234 | 12 cm | high -----------+-----------+--------------------- 1234 | 6 cm | low If somebody searches for an item that is 8 cm long, I want the results to be item 1234 and any other items that span that range. I'm not sure how to do this? array_fill ? I don't know. I don't want to slow down the database too much, and I don't want to have to put an entry for every single length each item could be. Any suggestions? Hi, i'm new here and have a straightforward question. On a server I use I have this script and we use it to force the download of mp3 files on a single click of a link. (Avoid opening in an internet audio buffering plug in or application) Code: [Select] <?php $filename = $_GET['file']; // required for IE, otherwise Content-disposition is ignored if(ini_get('zlib.output_compression')) ini_set('zlib.output_compression', 'Off'); // addition by Jorg Weske $file_extension = strtolower(substr(strrchr($filename,"."),1)); if( $filename == "" ) { echo "<html><title>Download Script</title><body>ERROR: download file NOT SPECIFIED. USE force-download.php?file=filepath</body></html>"; exit; } elseif ( ! file_exists( $filename ) ) { echo "<html><title>Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>"; exit; }; switch( $file_extension ) { case "pdf": $ctype="application/pdf"; break; case "exe": $ctype="application/octet-stream"; break; case "zip": $ctype="application/zip"; break; case "doc": $ctype="application/msword"; break; case "xls": $ctype="application/vnd.ms-excel"; break; case "ppt": $ctype="application/vnd.ms-powerpoint"; break; case "gif": $ctype="image/gif"; break; case "png": $ctype="image/png"; break; case "mp3": $ctype="audio/mpeg3"; break; case "jpeg": case "jpg": $ctype="image/jpg"; break; default: $ctype="application/force-download"; } header("Pragma: public"); // required header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: private",false); // required for certain browsers header("Content-Type: $ctype"); // change, added quotes to allow spaces in filenames, by Rajkumar Singh header("Content-Disposition: attachment; filename=\"".basename($filename)."\";" ); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".filesize($filename)); readfile("$filename"); exit(); ?> I recently got an email from my service provider quoting the following Quote Hello, I apologize, but I was forced to suspend the script /home/mezerik/********/forcedownload.php as it was causing a high load on the server, and due to it affecting all of the other accounts on the system, I forced to take immediate action for the health of the server. Unfortunately I do not have any specific recommendations for this script, however, in general, adding some sort of caching mechanism, where the script does not need to generate a new page with every request, helps to lower the over load that a script will cause. Likely the original author or support group of the software that you are using will be able to help you to understand how to add something of this nature. If you reply back to this with your IP address (http://www.******.com/ip.shtml) we will be more than happy to go ahead enable HTTP access for you, so that you can safely work on the script without it causing further issues. Please let us know how you would like to proceed. I am not sure what is wrong with the script and if it is insecure to the server and should be edited or removed. I have a class that I created, halfway down my page I call a function from the class which prints some code and also changes a variable inside the class. It's a search class basically it prints out the search results and saves the total amount of results into the variable. I want to display the amount of results above the results like so:- echo $Search->results; $Search->GetResults('foo'); The problem is that $Search->results will be equal to NULL until the variable is updated in the function GetResults. Hope that makes sense, am I going about this wrong? Hello, I am including file SimpleImage.php in my php file. The script will handle everything perfectly, but if I try and upload a very large resolution image 2560x1440 the script just dies and no resizing is made. The file size of the high resolution image is well below 2 Mb, so there is no file size issue. I am troubled. Any ideas? Thanks.

The graphics I need printed print really well when put into a Word document at 300 resolution - so I can't see why there should be any problems inserting into a PDF - these graphics are PNG ones Unfortunately, if I insert the same PNG format into the PDF via the PHP code, the graphic turns out to be REALLY big Just looking for advice Thanks OM Hello again, I got a problem with one of my pages that uses MySql. I didn't expect my site to shoot up into the 1000's per hour but it has but has destroyed the loading time of one of my pages. Below is the function that is super slow! Code: [Select] function get_top($timeframe='today', $time=10, $friends=true, $limit=5, $unique=true, $me_only=false){ if($friends===false){$q='';}else{ $q=' AND (username IN ('; // This array can have upto 500 items in it. global $friend_id_array, $me;$tarray=$friend_id_array; $tarray[]=$me['id']; $x= implode(',',$tarray);$q.=$x; $q.= '))'; } if($me_only){ $q=' AND username = \''.$me['id'].'\' '; } if($timeframe=='today'){ $q_timeframe='AND DATE(thedate) = DATE(NOW()) AND YEAR(thedate) = YEAR(NOW())'; // Checking the date could be slow }else if($timeframe=='week'){ $q_timeframe='AND WEEK(thedate) = WEEK(NOW()) AND YEAR(thedate) = YEAR(NOW())'; }else if($timeframe=='month'){ $q_timeframe='AND MONTH(thedate) = MONTH(NOW()) AND YEAR(thedate) = YEAR(NOW())'; }else if($timeframe=='all'){ $q_timeframe=''; } if($unique){$q_unique='GROUP BY username';} $query="SELECT MAX(score) as highscore, username, timeframe, thedate FROM other_click WHERE (timeframe = '$time') $q $q_timeframe $q_unique ORDER BY highscore DESC LIMIT 0, $limit"; // A very long query $result=@mysql_query($query)or die(mysql_error()); if(@mysql_num_rows($result)>0){ while($row=@mysql_fetch_array($result)){ // Maybe resorting the array makes it super slow $id_array[]=$row; } return $id_array;}else{return false;} } I've commented the lines which I think maybe making this page load slowly. I also thought the way the page is loaded. The page is called 6 times per user but with different settings eg, Friends only and only scores added today. Please help because this is crippling my site. Thank-you all Paul Hi All,
I want to copy into a table values from another table that partially match a given value, case-insensitively. So far I do as follows but I wonder whether there is a quicker way.
$input_table=array('1'=>'toto','2'=>'tota','3'=>'hello','4'=>'TOTO','5'=>'toto'); $input_table_2 = array_map('strtolower', $input_table); $value_to_look_for='Tot'; $value_to_look_for_2=strtolower($value_to_look_for); $output_table=array(); foreach ($input_table_2 as $k=>$v) { if(false !== strpos($v, $value_to_look_for_2)) { $output_table[]=$input_table[$k]; } }One drawback is that $input_table_2 is 'foreached' whereas there might be no occurrences, which would lead to a loss of time/resources for big arrays. Thanks. Hello, I need some help. Say that I have a list in my MySQL database that contains elements "A", "S", "C", "D" etc... Now, I want to generate an html table where these elements should be distributed in a random and unique way while leaving some entries of the table empty, see the picture below. But, I have no clue how to do this... Any hints? Thanks in advance, Vero Hello everyone. I need help with the following PHP APP. I am running on (Version PHP 7.2.10) I am trying to have a page table form on table.php pass the input variable of “5-Numbers” to another page called table_results.php I want that variable string of “5-Numbers” to be compared against 4 arrays and output any duplicates found within each of those 4 lists. If nothing is found, I still want some visual output that reads “None found”.
Lets pretend I have the following example .. On table.php, I typed inside my table form the 5-Numbers .. INPUT: 2,15,37,13,28 On table_results.php, the 4 arrays to be compared against my input numbers “ 2,15,37,13,28” are ..
$array_A = array(2,6,8,11,14,18,24); $array_B = array(1,2,9,10,13,14,25,28,); $array_C = array(1,3,7,9,13,15,20,21,24); $array_D = array(4,5,12,22,23,27,28,29);
So my output should read as follows below .. OUTPUT:
TABLE COLUMN 1 COLUMN 2 ROW 1 Matches Found Results .. ROW 2 GROUP A: 2 ROW 3 GROUP B: 2,13,28 ROW 4 GROUP ? 13,15 ROW 5 GROUP ? 28 ROW 6 5#s Input: 2,15,37,13,28
Please let me know if anyone has any suggestions on how to go about it. Thanks. Edited January 1, 2019 by Jayfromsandiego Wanted to include image example Hi All ,
I have a small table with 4 fields namely Day_ID, Dues, Last_Visit, Points. where Day_ID is an auto-increment field. The table would be as follows:
Day_ID -- Dues --- Last_Visit --- Points.
1 --------- 900 -------- 1/12 -------- 6
2 --------- 700 -------- 4/12 -------- 7
3 --------- 600 -------- 7/12 -------- 5
4 --------- 600 -------- 9/12 -------- 6
5 --------- 600 -------- 10/12 ------- 6
6 --------- 600 -------- 14/12 ------- 6
So this is the record of a person's visit to say a club. The last row indicates the last date of his visit to the club. His points on this date are 6. Based on this point value of 6 in the last row I want to retrieve all the previous BUT adjoining all records that have the same Points i.e. 6.
So my query should retrieve for me, based on the column value of Points of the last row (i.e. Day_ID - 6 ), as follows:
4 --------- 600 -------- 9/12 -------- 6
5 --------- 600 -------- 10/12 ------- 6
6 --------- 600 -------- 14/12 ------- 6
This problem stated above had been completely resolved, thanks to a lot of help from Guru Barand by this following query :-
$query = "SELECT cv.day_id, cv.dues, cv.last_visit, cv.points FROM clubvisit cv WHERE last_visit >= ( SELECT MAX(last_visit) FROM clubvisit WHERE points <> ( SELECT points as lastpoints FROM clubvisit JOIN ( SELECT MAX(last_visit) as last_visit FROM clubvisit ) as latest USING (last_visit) ) )";I am using this and it works perfectly except that now there is a slight change in the table because the criteria for points is now dependent on more than one column cv.points and is more like cv.points1, cv.points2, cv.points3 etc. So now I need to make a selection based on each of these cv.points columns. As of now I can still get the results by running the query multiple times for each of the cv.points columns ( seperately for cv.points1, cv.points2, cv.points3) and it works correctly. However I am wondering if there is a better way to do this in just one go. This not only makes the code repetitive but also since the queries are interconnected, involves the use of transactions which I wish to avoid if possible. The values that I require for each of the cv.point columns is 1. day_id of the previous / old day on which the cv.points value changed from the current day value, and 2. cv.points on that old/ previous day. So for example if the table is as below: Day_ID -- Dues --- Last_Visit --- Points1 --- Points2. 1 --------- 900 -------- 1/12 ----------- 9 ------------ 5 2 --------- 600 -------- 4/12 ----------- 6 ------------ 6 3 --------- 400 -------- 7/12 ----------- 4 ------------ 7 4 --------- 500 -------- 9/12 ----------- 5 ------------ 8 5 --------- 600 -------- 10/12 ---------- 6 ------------ 8 6 --------- 600 -------- 11/12 ---------- 6 ------------ 8 7 --------- 600 -------- 13/12 ---------- 6 ------------ 7 8 --------- 500 -------- 15/12 ---------- 5 ------------ 7 9 --------- 500 -------- 19/12 ---------- 5 ------------ 7 Then I need the following set of values : 1. day_id1 -- Day 7, points1 ---- 6, days_diff1 -- (9-7 = 2) . // Difference between the latest day and day_id1 2. day_id2 -- Day 6, points2 ---- 8, days_diff2 -- (9-6 = 3) 3. day_id3 -- .... and so on for other points. Thanks all ! Hi
I am very new to PHP & Mysql.
I am trying to insert values into two tables at the same time. One table will insert a single row and the other table will insert multiple records based on user insertion.
Everything is working well, but in my second table, 1st Table ID simply insert one time and rest of the values are inserting from 2nd table itself.
Now I want to insert the first table's ID Field value (auto-incrementing) to a specific column in the second table (only all last inserted rows).
Ripon.
