I was assigned to create a simple php game as a part of my grade, but i got stuck. I'm not really a php expert and this isnt really working. I managed to get some of the code/game working, but it's pointless imo. I'm looking for someone who would take 3 mins and fix this code for me. The game is called "Random number guessing game." From the title you can see that the game is not really complicated.
Code:
<html>
<head>
<title></title>
</head>
<body>
<h1> Ugani Random!</h1>
<? php
if(isset($_POST['submit']))
$x = $_POST['x'];
$num = $_POST['num'];
$x = rand(1, 10)
if($num<$x)
{
echo " Your number is higher! "<br />
}
if($num==$x)
{
echo " Correct! Press Reset to try again! "<br />
}
if($num>$x)
{
echo " Your number is lower! "<br />
}
?>
<p>
<form>
<input type="number" name="quantity"> <br />
<button type="submit" value="<? echo $x?>">Submit</button>
<button type="reset" value="<? echo $num?>">Reset</button>
</form>
</p>

Hello, I am trying to create a simple game random number guessing game in PHP. Currently, I have an HTML page with a form on it where the user enters a number. Then when the user clicks the submit button on the form, their number is passed onto the second page. On the second page, I have some PHP code that generates a random number between 1 and 20, then it checks to see if the two numbers are the same. If they are the same, it says correct. If the guess is higher, it says so. If the guess is lower, it says so. I also made it display a form to re-guess the number (if the initial guess was incorrect). The problem I have is when the user attempts to re-guess the number. Whenever the user attempts to enter a new guess, the random number changes. I want to make it so that the random number stays the same as it is. Any help? Here is the Code for the first HTML page: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>phpNumberGame</title> <link href="style.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="main"></div> <div id="enterNumber"> <form action="result.php" method="post"> Enter a number: <input type="text" name="inputnumber" /><br /> <input type="submit" value="Guess" /> </form> </div> </body> </html> Here is the code for the second page: Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>result</title> <link href="style.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="main"></div> <div id="enterNumber"> <?php $number_actual = rand (1,20); $number_guess = $_REQUEST["inputnumber"]; echo "You chose: " . $number_guess . "<br />"; echo "The random number is: " . $number_actual . "<br />"; if ($number_guess==$number_actual) echo "You guessed <b>Correctly!</b>"; elseif ($number_guess<$number_actual) { echo "You are too <b>Low</b>!"; echo "<br />"; echo "<br />"; echo "Try guessing again..."; echo "<form> <input type='text' name='inputnumber' /> <input type='submit' value='Guess' /> </form>"; } elseif ($number_guess>$number_actual) { echo "You are too <b>High</b>!"; echo "<br />"; echo "<br />"; echo "Try guessing again..."; echo "<form> <input type='text' name='inputnumber' /> <input type='submit' value='Guess' /> </form>"; } ?> </div> </body> </html> Here is what I have so far on my website, you can see it he http://joshkautz.com/phpNumberGame/phpNumberGame.html I think I included everything necessary for people to give input, if not please let me know and I will give more information! Do I need to redo things completely? Any advice would be greatly appreciated. Thanks a ton! Can someone help me create this?? Upon outside entry, a random number is chosen between 1 and 10. Use this function to generate the guess number $guessnum = rand(1,10); // you may change the variable name The user tries to guess this number by choosing from a selection list of possibilities. The user "loses" if there are three failed attempts. For reentrant activations the selection list must be sticky and the same guess number must be maintained. The guess number and the attempt number must both be propagated through hidden inputs. Here is a screen shot: Upon outside entry, or using the "Start Over" hyperlink (with the list activated): Let's suppose the number to be guessed is 6. I select 4 and guess it. Response should say "Try #1" I select 9 and guess it. Response should say "Try #2" I select 3 and guess it. Response should say "You Lose" At this point assume that we must "Start Over". This time, suppose the generated number is 8. I select 8 and guess it. Response should say "You Win" Again, assume we must "Start Over". 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...)
Edited by Mythion, 17 August 2014 - 02:34 AM. I'm getting the dreaded " Invalid parameter number: number of bound variables does not match number of tokens" error and I've looked at this for days. Here is what my table looks like:
| id | int(4) | NO | PRI | NULL | auto_increment | | user_id | int(4) | NO | | NULL | | | recipient | varchar(30) | NO | | NULL | | | subject | varchar(25) | YES | | NULL | | | cc_email | varchar(30) | YES | | NULL | | | reply | varchar(20) | YES | | NULL | | | location | varchar(50) | YES | | NULL | | | stationery | varchar(40) | YES | | NULL | | | ink_color | varchar(12) | YES | | NULL | | | fontchosen | varchar(30) | YES | | NULL | | | message | varchar(500) | NO | | NULL | | | attachment | varchar(40) | YES | | NULL | | | messageDate | datetime | YES | | NULL |Here are my params:
$params = array(
':user_id' => $userid,
':recipient' => $this->message_vars['recipient'],
':subject' => $this->message_vars['subject'],
':cc_email' => $this->message_vars['cc_email'],
':reply' => $this->message_vars['reply'],
':location' => $this->message_vars['location'],
':stationery' => $this->message_vars['stationery'],
':ink_color' => $this->message_vars['ink_color'],
':fontchosen' => $this->message_vars['fontchosen'],
':message' => $messageInput,
':attachment' => $this->message_vars['attachment'],
':messageDate' => $date );
Here is my sql:
$sql = "INSERT INTO messages (user_id,recipient, subject, cc_email, reply, location,stationery, ink_color, fontchosen, message,attachment) VALUES( $userid, :recipient, :subject, :cc_email, :reply, :location, :stationery, :ink_color, :fontchosen, $messageInput, :attachment, $date);";
And lastly, here is how I am calling it:
$dbh = parent::$dbh;
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
if (empty($dbh)) return false;
$stmt = $dbh->prepare($sql);
$stmt->execute($params) or die(print_r($stmt->errorInfo(), true));
if (!$stmt) { print_r($dbh->errorInfo()); }
I know my userid is valid and and the date is set above (I've echo'd these out to make sure). Since the id is auto_increment, I do not put that in my sql (though I've tried that too), nor in my params (tried that too). What am I missing? I feel certain it is something small, but I have spent days checking commas, semi-colons and spelling. Can anyone see what I'm doing wrong?
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? 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"; } ?> 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? 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 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? 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.

Can you help me to solve this problem ?
Edited by danchi, 17 October 2014 - 10:25 AM. I need to display a number(the number is retrieved from the db) in the form input field such that only the last 4 digits is visbile, the remaining can be masked as * or X or whatever is applicable. I know the last 4 can be obtained as follows: Code: [Select] $number=substr($number,-4,4); But when i hit the submit button the form validates the input field and checks if the number is a valid number of a specific format. Therefore when I click on the submit button then I should still be able to unmask the masked numbers or do something similar that would help me validate the whole number. Code: [Select] <input type="text" name="no" value="<?php if(!empty($number)){ echo $number;} ?>"> I'm having a mini application developed to create A4 PDF's using PHP A key part of the project needs to be able to insert high quality graphics into the document that when printed out look really sharp Some of the graphics are variable and don't always have to be printed I just wanted to know if there was a general guide on what graphics and quality to use? The graphics I need printed print really well when put into a Word document at 300 resolution - so I can't see why there should be any problems inserting into a PDF - these graphics are PNG ones Unfortunately, if I insert the same PNG format into the PDF via the PHP code, the graphic turns out to be REALLY big Just looking for advice Thanks OM Hey I have a string that looks like the following: Quote top-php-tutorials-2.html I have a script that cycles through each page. The 2 in the quote above is the page number. How can I extract the number between the - and the .html and replace it with another number? I've tried Code: [Select] substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long Any input would be appreciated Hello again, I got a problem with one of my pages that uses MySql. I didn't expect my site to shoot up into the 1000's per hour but it has but has destroyed the loading time of one of my pages. Below is the function that is super slow! Code: [Select] function get_top($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 hello, i have a start time and an end time (no dates). the following works great, except for when the start time is at night, and the end time is in the morning. im thinking if i can do an if the number is negative, add 24, that it will resolve my issue. any ideas? Code: [Select] $tbilled = $tfinish - $tstart; |
