At the moment I am writing a cricket management game and and each hour each team is updated with the code Code: [Select] <?php #Players MUST be updated from this screen so they cna get team bonuses $teamUpdateTime=$team['teamUpdateTime']; #This is the time that the team is updated $teamMorale=$team['morale']; #Get the teams morale while($teamUpdateTime<$updateTime) { #Keep looping through this until we are up to date echo "<BR>".$team['name']; #Work out changes to team morale if($teamMorale>1000) $teamMorale -= mt_rand(0, 3); #If team morale is high then lower it if($teamMorale<1000) $teamMorale += mt_rand(0, 5); #If team morale is low then increase it $moraleBonus=0; #Reset the variable $confidenceBonus=0; #Reset the variable $injuryBonus=0; #Reset the variable $energyBonus=0; #Reset the variable $teamUpdateTime += 3600; #Add an hour to the time include("hourly_update_player.php"); #Do players now } #Save the team $sqlTeam = "UPDATE teams SET morale='$teamMorale', teamUpdateTime='$teamUpdateTime' WHERE teamID='{$team['teamID']}'"; if(!mysql_query($sqlTeam, $sqldb)) die('Error: ' . mysql_error()); //Update the record, if there is an error then show it ?> the line include("hourly_update_player.php"); #Do players now then activates the following code Code: [Select] <?php #Playeres will have to be updated with the team because we have to check for team medic $players = mysql_query("SELECT playerID, name, injuryTime, energy, morale, confidence, fitness FROM players WHERE teamPlayedFor='$team[teamID]'"); #Get all the players of the team while($player = mysql_fetch_array($players)) { #Go through all the players of the team echo "<BR>".$player['name']; # Do all the updating of player stats here. I won't put the full code here as it is not needed for the question on phpfreaks. $sqlPlayer = "UPDATE players SET energy='$energy', confidence='$confidence', morale='$morale', injuryTime='$injuryTime' WHERE playerID='{$player[playerID]}'"; #Update player if(!mysql_query($sqlPlayer,$sqldb)) die('Error: ' . mysql_error()); //Update the record, if there is an error then show it } ?> Each team has around 25 players to update. With ten teams (250 players all up) in the game (the game is still pre-alpha) to test it all this takes 8 seconds to go through all the teams and their players. Unfortunately in this 8 seconds nobody else can use the database as it locks it up. I tried to have the players update by itself (so it only has to go through the players database once) but cannot work out how to have team affects on the player - for example if the team has a specialist batting coach then the player gets an extra batting point each hour so it needs to go through the teams first. MY QUESTIONS A) How can I speed this up? When the game goes into the public domain I would like to see around 1-5 thousand teams, this could take up to 800-4,000 seconds - waaaay to long. B) When it is updating the database I can't play the game, it simply says loading until the updates are finished and then continues as normal; with thousands of teams I do expect a bit of delay but how can I keep parts of the database open that aren't being used? C) Each time I go through a team the players database is reloaded, can JOINS fix this? Or is there another way of doing this? Hi all! Ok I am trying to put a delimited list like so , EX. item qty, item name, item price | item qty, item name, item price | item qty, item name, item price | etc. into an array so I can access it like this - $product[0] = qty, $product[1] = name, etc. My code just isnt working. This is what I have so far. $prod = array(); //breaking products text down for display $products1 = explode("|", $products); $num_prod1 = count($products1); $count = 0; foreach($products1 as $p) { $prod[] = $p; $products2 = explode(",", $p); foreach($products2 as $p2) { $prod[$count] = $prod[$count][$p2]; } $count++; } Hi, Would someone please give me some assistance on how to display random products from my database I need to display a maximum of 6 images and there link in two rows of 3 so; [image] [image] [image] [image] [image] [image] and each image would have something like; <a href="<? echo $row['product_link'] ?>"><img src="<? echo $row['product_image'] ?>"/></a> but i don't know how to display these at random and make sure only 6 appear at a time. Thanks for any help, hope you understand what im trying to explain hi. i am making mcq type test. lot of questions stored in db, i want that some of them retrieve i.e. 5 after 5 test should end. how is hould do, query is ...SELECT question,questionid, choice1, choice2, choice3, choice4, answer FROM questionbank order by RAND() limit 1";... limit 1 is used for display one question in a page. I'm trying to generate a unique "dosieid" number for my web site.My web site is a human resources program solution, in that program users create dosie of their workers in their firm ...random dosieid needs me so when user createing dosie in field dosieid automaticly show the dosieid-s that are not used before...the dosieid that don't exist in database. In other case I would use auto increment but in this case dosie is not created yet. And in form dosieid must be option to change the number if random is not fine with a user. One more hint the numbers must bee from 1 to 9999. Can someone help mee? I have try many codes but i have not find something like one with this spec. This is what I have do so far. It gets the random number but I don't know how to compare that random number with database row "dosieid" ? Code: [Select] <? $id_num = mt_rand(1,9999); $query = "SELECT dosjeid FROM albums"; $result = mysql_query($query) or die(mysql_error()); while($account = mysql_fetch_array($result)){ if ($id_num == $account['id']){ $id_num = mt_rand(1,9999); } } echo"$id_num<br>"; ?> hi!, is it possible to use rand() to generate unique number that will be saved in a database as a primary key? Since i dont want to have numbers like 00001 incrementing on the table. They dont look like real account numbers... i need something like 45642 or 95452 and the like. thanks in advance. Hello, I am using the following code to display images managed by a MySQL database. Basically another program manages a bunch of images, but this script displays certain ones (ones with INCLUDE = 1 in the database) on my main page. My question is, is there an easy way to limit the number of images it displays, say to 5? I'm not too concerned which images actually display (ascending or descending)... or better yet, random! Most importantly, I only want five to display. Each image will be linked to the full page, which displays all the images. Any ideas? Thanks! Code: [Select] <?php $username="XXXXXXX"; $password="XXXXXXX"; $database="XXXXXXX"; mysql_connect(localhost,$username,$password); @mysql_select_db($database) or die( "Unable to select database"); $query="SELECT * FROM ft_form_12 WHERE col_24='1'"; // $query="SELECT * FROM ft_form_12"; // SELECT * FROM ft_form_12 WHERE col_24='1' $result=mysql_query($query); $num=mysql_numrows($result); mysql_close(); ?> <?php $i=0; while ($i < $num) { $f20=mysql_result($result,$i,"col_23"); //Photo file name $f21=mysql_result($result,$i,"col_24"); //INCLUDE ?> <a href="http://www.domain.com/display_whole_page.shtml"><img src="http://www.domain.com/the_file/pictures/<?php echo $f20; ?>" height="50" border="0"></a> <?php $i++; } ?> Hi, I'm a researcher (and complete coding noob), and am planning a longitudinal study that requires e-mail follow-up with subjects taking an initial survey. For purposes of ethics/anonymity due to sensitive survey data, I'd like the acquired e-mails to be saved uncoupled from the survey responses; this is simple to deal with, and I use a basic PHP e-mail form, which injects the email address in a table in MySQL in a different server than the one used for the survey. The issue is that the e-mails are saved in the MySQL database in order of injection, thus it is still theoretically possible for me to link the e-mails back to the survey responses (which have a time stamp that I cannot remove). Ideally I would like not to be able (at all) to link the e-mails to the survey responses, and one way to do that (since I don't save the e-mail injection timestamps in MySQL) might be to have the e-mails saved in MySQL in a random order. Not sure if this is possible, and not even sure if this would be via PHP or MySQL side of things. The server is on godaddy and uses Starfield interface for MySQL but I cannot find an option for random insert/saving of table items (emails). They are saved in order of injection. Any solution for this? Thanks, I need a way to generate a random number and insert into a database, and I need the database to not contain any duplicates of that number. I basically need to generate a RMA # (Return Merchandise Authorization Number), so the numbers absolutely CAN NOT be duplicate. I have no ideas how to go about this. Should I generate a random number, search the database and see if there's a duplicate, and if there is re-run the script? Hi, What I'm trying to do is create a script that generates a random list of cars whenever it is run. I have a list of available cars in a MySQL database. I'm just not sure how to get php to generate a list of, say, 20 cars, that are randomly picked from the cars in the database. I may also want to add other statistics like MPG (also already in the database). Can anyone show me how to do this? And is it possible to format the returned data in a table or div format? Thanks in advance Unk Ok say i have a database with users who have a video url field for them to enter a video url to be submitted to the database, im trying to create a page where the videos will be displayed one at a time for example ' 1st video plays then it switches to the next random video from the database and so on' i want only to play so many seconds of the video before it switches as they will be presentations so i dont want viewers to watch them all in full, could anyone help me out with some code or feedback on this please? I dont know how to word this really. what I want to do is Code: [Select] $Var[] = 3; $Var[] = 6; $Var[] = 2; $Var[] = 17; for($i=0; $i!=count($Var); $i++) { echo "#$i: ".$Var[$i]."\n"; } I know I might be able to use rand() but I need it to echo ALL of the variables in the array in a random order, I know if I use count to find out how many variables there are that it would echo them 4 times randomly but might echo the same variable 2 times making it to where it only echos 3 different varables, if I am being confusing please let me know, I just want to get this resolved, thanks! Hey guys does anyone know how i would go about generating a random word from an array? For example: $words = array("[apple]","[banana]","[kiwi]"); how would i have php choose one of these words and then spit it out? Thanks!!! Hello all, I am newbie to php programming, any suggestions or advance greatly appreciated. I can't figure out how to output two array random numbers in ascending order. <?php $l_numbers = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47); $mega = range(1, 27); for($i = 0; $i <= 4; $i++) { $random1 = array_rand($l_numbers); echo "$random1 \n" ; } for($e = 1; $e <= 1; $e++) { $random2 = array_rand($mega); echo "<p> Mega number is $random2 </p>"; } echo "Winning numbers are $random1 and mega $random2"; ?> example: Winning numbers are 3,5,10,17,39 and mega 5. I have it to where it groups two parts of the Array randomly but I need to make it where it won't pair the same together, or if it has already been paired with a team then use another team. Each value of the array can only be used once. Here is my code shuffle($teamname); $loopCount = $games; for ($i = 0; $i < $loopCount; $i++) { $player1 = array_pop($teamname); $player2 = array_pop($teamname); if(is_null($player1)) { echo 'Not enough different teams to create '.$games.' games'; break; } // output to screen echo "Team: " . $player1 . " Vs Team: " . $player2 . "<br />"; } } Hi guys! i got this code: Code: [Select] <? $x = "abcde"; str_split($x); for ($k=0; $k<=119; $k++){ $ax = array($x[0],$x[1],$x[2],$x[3],$x[4]); shuffle($ax); $text = implode("", $ax) . ""; echo $text; echo "<br />"; } ?> if you test it you see that it is working but giving me allot of duplicates results! there is a way to ignore duplicaes while it is runing? thanx. I have a user table that holds email addresses and for testing purposes I am trying to replace every email address with an email address defined in an array. I would like to randomly choose an email address from the array and update the table with this address. When I run the following code it randomly chooses a email address from the array but then updates every row with this one email address. Can you someone please let me know what I am doing wrong. Thanks in advance. Code: [Select] $query = "SELECT * FROM user '"; $result = mysql_query($query); $input = array('email1', 'email2', 'email3', 'email4', 'email5', 'email6', 'email7'); $rand_keys = array_rand($input, 2); $replaceStr = $input[$rand_keys[0]]; while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $rand_keys = ""; $rand_keys = array_rand($input, 2); $replaceStr = $input[$rand_keys[0]]; mysql_query("UPDATE user SET email = '$replaceStr'"); } Hi all, This is a piece of code of my php page and what I need is that $n1 till $n4 is filled. Somehow only $n1 is filled. Can anyone tell me what I'm doing wrong here. Thnx Ryflex $sql = "SELECT name FROM unittype WHERE type = 1"; $result = mysql_fetch_array(mysql_query($sql)) or die("Could not find units"); $n1 = $result[0]; $n2 = $result[1]; $n3 = $result[2]; $n4 = $result[3]; echo "$n1 <BR> $n2 <BR> $n3 <BR> $n4"; |
