PHP - Timer For Multiple Instances
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') { $flag = '<img src="images/noflag.gif">'; $flagdesc = ""; $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. Similar TutorialsI 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 Edited August 25, 2019 by NotionCommotionHey all, I want to have an object that has a property which is an object containing instances of other objects. I try this: Code: [Select] class Blog extends Posts { public $has_posts; public function __construct($a,$b,$c){ $has_posts = (object) array_merge((array) $a, (array) $b, (array) $c); } } class Posts { public $b; public function __construct($b){ $this->b = $b; } } $post1 = new Posts(1); $post2 = new Posts(2); $post3 = new Posts(3); $blog = new Blog($post1,$post2,$post3); var_dump($blog->has_posts); //null foreach($blog->has_posts as $post){ //Invalid argument supplied for foreach() echo $post->b; } But as you see, has_posts is null, not an object containing other objects. Thanks for response. I'm trying to get a count of how many topics someone starts in a forum. I use XenForo, and they only count Posts, but I can order Posts by post_id and group those posts by thread_id to determine the initial instance of that topic. The problem I'm having is output. I'm getting the right User info, but the output is offset by one row: User 1 | 0 topics (because $c=0) User 2 | 128 topics (but those are User 1's #) User 3 | 0 topics (but those are User 2's #) User 4 | 141 topics (but those are User 3's #) etc
I realize as I play through the logic of the code, it's printing in that order. I can't seem to get the right order. I've tried various ways, with a couple of extra IF statements in there too.
$query = "select thread_id,user_id,username from ( select * from xf_post order by post_id ) x group by thread_id order by username,thread_id"; $results = mysqli_query($con,$query); echo mysqli_error($con); $c=0; $currentID = false; while($line = mysqli_fetch_assoc($results)) { if ($currentID != $line['user_id']) { echo '<div>' . $line['username'] . ', ' . $c; $currentID = $line['user_id']; $c=0; } else { $c++; } }
Hi I am building a product search engine using MySql and PHP (Jquery / AJAX). As i am getting the search results i wondered is it possible to count the instances of a category? For example: If i search for "Dell Laptops" i get 400+ results back because it has lots of laptops and accessories. What i am aiming for it to do is while looping through look at the categories and if its the first instanc eof it i want it to begin a count. until it has finished looping and then i can display it. Results: 436 [ Laptops(127) - Accesories (244) - Components(65) ] Im not even sure where to start here so any advice will be helpful Here is the code im using to generate the search: $id = str_replace(" ", "%", "$id"); $q = "SELECT * FROM products WHERE prod_name LIKE '%$id%' order by fee asc LIMIT 20"; I'm pretty sure this is really simple to do using the count function, but I am having a hard time finding examples on how to count the number of times a "SPECIFIC" word occurs in a file. For example, I just want to display how many times "this-word" occurs in "http://www.mysite.com/logfile.log". Any help would be appreciated. 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 Hi guys, For a project I made sort of a custom cron database. Database has 4 columns: ID (auto increment), TaskID, DateTime, Locked. I'm running a 1 minute cron in the form of a php script. The script itself starts with a query that loads a task with 'Locked != 'Y' and DateTime < NOW( ). It then locks the task (by flagging the 'Locked' field in the db) and launches another script that finishes it. That last script deletes the task when finished from the cron database. Problem is, at certain peek hours, the system would get laggy, there'd be a bunch of tasks stacking up and it would get behind on the schedule. In order to combat that, I made an extra 1 minute cron, launching the same script. Now, my problem: mysql is too slow In principle, there shouldn't be any problem: all tasks picked up by either instance of the script would be locked so the other instance wouldn't be able to pick up the same task. The problem occurs when both instances are booted at the same time (well, one after the other but with a minuscule time difference between them) and they both at the same time run the query to get a 'free' task from the database: the system will give them both the same task before either of the script instances has the time to lock it up. I'm trying to think of some solutions but I'd like your feedback on what solution would be best. - Putting an exclusive lock on the php file is not an option for me since I still want to run the script, I just need it to pick up an exclusive task. - Other option: having the script open with a random sleep of (1, 10) seconds, it will have the script instances pick up a task at a different time, giving the other instance time to lock it up. Obvious disadvantage: I'm losing time. - Using a file as a flag. Set a directory and create a file in it. Check if this is the only file in the dir, if yes: start right away. Otherwise: go to sleep for 2 seconds (should be plenty of time to run 2 queries in the other instance). What is the fastest method of doing a directory scan though, glob()? My question: what's the fastest/best way to solve this? Thanks! We have a 10 year old system that has 100's of php files that all connect to a central database using a single shared php include file that does a mysql_connect before any other code executes
include_once("db_connect.php");
mysql_query(...);
We never used the returned connection id (link identifier) from the mysql_connect function call as it was always implied in every subsequent mysql_query statement etc.
Now we've moved some of our bigger tables to a separate server, so we have to update small areas of some files that need to connect to this other system and send the old existing query to the new server instead of to the main server and process the results
So, going back through hundreds of files and converting mysql_query($string) to mysql_query($string, $connection1) is not practical
Possible solution one: anytime I need to use the new server I do this
------------------------------------------------------------------------------
mysql_connect(NEW_SERVER_IP,"...",""");
mysql_query($string);
...
// get back to normal
mysql_connect(OLD_SERVER_IP,"...","");
Possible solution two: modify the master include file
------------------------------------------------------------------------------
//add a new line ABOVE the existing mysql_connect statement...
$new_server=mysql_connect(NEW_SERVER_IP,"...",""");
mysql_connect(OLD_SERVER_IP,"...","");
and then anytime I need to use the new database I have to go back and modify all of the mysql_query,mysql_affected_rows, etc to reference the $new_server link identifier
solution one seems much simpler, but all of the mysql_connect reconnections I assume will be extremely inefficient
solution two seems cleaner but if I miss one mysql_ statement that needs the new connection object as a reference, the code will completely break or worse yet it will produce unexpected results
Example: If I miss converting a mysql_errno() function that really needs to now be mysql_errno($new_server) it would cause major issues.
So, I'm wondering if others have faced this dilema of migrating single mysql_connect code to multi mysql_connect mode and if there is a better way of going about implementing it.
Thanks in advance for any help

I have an array that looks like this:
array(5642) { [0]=> string(19) "2021-02-10 09:04:48" [1]=> string(19) "2021-02-10 09:04:54" [2]=> string(19) "2021-02-10 09:05:00" [3]=> string(19) "2021-02-10 09:05:06" [4]=> string(19) "2021-02-10 09:05:12" [5]=> string(19) "2021-02-10 09:05:18" [6]=> string(19) "2021-02-10 09:06:18" [7]=> string(19) "2021-02-10 09:06:24" }
I need to group the instances any time there is more than a 6 second gap between elements. So 0 =>5 would be one array and 6 and 7 would be a new array.
Ive been able to produce the following but its not ideal

I need a quick fix to solve an urgent problem..
I used to do some coding years ago but the old grey matter is not so responsive these days and I have been up all night trying to resolve a problem.
I have built a website for my daughters and created a simple web form but I have come unstuck. All those skills I once took for granted are gone.
So here's where I am at. I've created an input form_mail.html, a contact.php and a reply.html page uploaded them to the Server and hit an error when I tried to send a message. The problem it seems is with the PHP.ini File.
In short I don't have one Duh! Yes I know I should go back and study and that much I intend to do I am currently installing xxampp, MySQL and php on my new laptop.
But in the meantime I need your help urgently..
What code do I need in the php.ini file to make the Form Mail work?
Is there somewhere on the web where I can see a simple code, I am just too tired to wade through heavy docs right now.
Your help would be much appreciated at this time.
Sincerely
Tam
Can someone show me the way? I am creating a online examination with time pressured. For example Part I of examination is only good for 20 mins. now if 20 mins is over it will be lock or good as submit. How will I do that? tnx everyone. Hello. Well i'm trying to make a timer to execute some code. Basically I want 3 minutes, every 3 minutes a piece of code is activated, then another 3 minutes later it does so again. But I have tried different ways of doing this, I tried with cookies and found out the person with the cookie is the only one that can refresh the page to activate the code. Same with sessions. And all the others are usually interrupted and start the timer again when the page reset. So yeah, I don't want it to be interrupted by refreshing. So any help please? I also tried with timestamps, this has proven to be the best way but I can never get it working 100% How am i able to setup a countdown timer? I use the time(); function and want to compare that time with another time that is 8 hours ahead to form a countdown timer, how am i able to do this using php? Can anyone help me to make a countdown timer in php? so basically i've made a quiz.. but i want it to have a time of 1 hour 30 mins.. but i dont have any idea of how to make a timer Hi, I'm new to the forum, I have a slight issue with my script. Basically, I need to figure out a script that will allow me to do the following: - The user defines x amount of ours to count down (ie. 16 hours, 8 hours, 4 hours) - The script then starts the count down of the x hours - I need the script to count between 08:00 - 20:00 after 20:00 it needs to stop, then start again at 08:00 - The script also need to stop throughout the weekend (ie counts until 20:00 on friday, stops saturday & sunday, then starts 08:00 on monday) Can this be done? If so, any pointers or help? Many thanks, Lewis. Here's the code for the countdown timer. It works. At the end of the countdown, it's suppose to show the message "EXPIRED". But that message only shows once I reload the page. The countdown itself stops at 00:00:01. Is there a way to automatically show the message after that, instead of reloading the page to show it? <style> div#counter{ margin: 100px auto; width: 305px; padding:20px; border:1px solid #000000; } div#counter span{ background-color: #00CAF6; padding:5px; margin:1px; font-size:30px; } </style> <?php $target_date = '2019-01-12 05:40:00'; $timeLeft = (strtotime($target_date) - time()) * 1000; ?> <script src="javascripts/timer.js"></script> <script> $(document).ready(function(){ var timeLeft = <?php echo $timeLeft ; ?>; var timer = new Timer($('#counter'), timeLeft); if (timeLeft <= 0) { $('#counter').text('EXPIRED'); } }); </script> <div id="counter"> <span class="hour">00</span> <span class="min">00</span> <span class="sec">00</span> </div> Edited January 11, 2019 by imgrooot I don't know if this can be done in PHP, but what I'm wanting to do is calculate the amount of time a user has spent in a session. I am planning on making a script that allows users to race through questions and the person who does it the fastest is the winner. Could someone help me out with this? Thanks Can anyone help me with a 60 second timer for my website. I want to display the following text to my customers at the top of the page: "You will be automatically redirected to homepage in [timer]" In my header I have the following code: <meta http-equiv="refresh" content="61;url=home.php"> Hi all, I would like to create a timer showing a countdown from 0% to 100% (representing "power") ending at noon GMT on Sunday 4th September. The countdown started a few weeks ago, hence as of 1pm GMT on Tuesday 1st March, the countdown should be at 15% The "power" increases by 5% every 11 days so by my calculations, the percentage in our countdown should increase by 0.01% every 1900.8 seconds. So, with this theory, how would I go about coding it? I guess since I use GMT, I need to take a timestamp in GMT first, then calculate the difference between this and Sunday 4th September at 12.00pm. I am not sure though which format of time/date is best to do the calculation. Would it be better to use Unix time? Any help, suggestions and/or code is greatly appreciated. Skulty I am currently in the process of creating an online time based game. One of the big things is that users get gold every half an hour :00 & :30. What I am trying to do is offer a physical clock so that users can see how much time is left before they more more gold. I have been trying to do this using PHP. All I have currently is the time, but would like something like "$minutes until more gold". This is currently what I have now: (added 1 hour for EST.) <?php echo date("h:i A",time()+60*60); ?> |
