PHP - Resize Div's Based On Usage (php/javascript)
I was wondering how to resize DIVs based upon their usage. I have some vague ideas of how to do it, but not sure. Basically, the more a user clicks a DIV, the large it becomes relative to all other DIVs (no DIVs ever disappear!)
Any ideas? Similar Tutorialsthe difference between memory usage and bandwidth usage? I did a test with 500 rows in table, got 2.36mb memory usage, and then once without 500 rows in table, i got 2.34 (IN MBS) memory usage, can that translate into bandwidth usage? somone told me that bandwidth usage != memory usage, how so? it does effect it some doesn't it ? Hi, My hosting disabled my account because my site used too many system resources (CPU). There is no way for me to know how much CPU my site is using since i am not a psychic or god so no clue how they expect me to monitor this or fix this (the site has been running just fine for 2 years with the same code). Is there any code that can tell me how much CPU my site is using on the server? Thanks in advance, Jay For example, take a look at this: https://code.google....p/phpwebsocket/
When I run the server, it works fine and I am using the server for my Inventory system on my game. When users drag and drop items in their inventory to change position, it sends the data to the html 5 websocket server, and updates the positions accordingly/etc. And I will use it for a bunch of other stuff later.
My question is: What kind of VPS would I be looking for in terms of ram/cpu power to keep a websocket server like this up 24/7? Is it more memory intensive than socket/io/nodejs? Or what? How can I test these things? Looking at cmd.exe or php.exe in my task manager when having it run on my local windows machine isn't really a good way to test performance, or to estimate how much ram or VPS/CPU power of a server I'll need before launch. I can get a idea, but I don't think it's going to be close to reality. That's why I'm asking you guys here if you would know. Thanks
Edited by Monkuar, 17 January 2015 - 12:24 AM. Hi guys, Yet another rookie question, trying to implement this: I have a function:
<?php //MyHelper.php
function getnext( $name )
{
$conn = DB::table('counter')->where('name', $name )->first();
$result = $conn->findAndModify(
['name' => $name],
['_id' => ['seq' => 1]],
['seq' => true],
['new' => true, 'upsert' => true]
);
return $result['seq'];
}
?>
And I am calling it so:
$db_array = getnext(array('name' => 'role_id'));
print_r( $db_array);
Results in call to a member function on NULL, not sure where I'm going wrong! It is making a connection and the counter table has a 'role_id' in it. Can anyone tell me where I'm going wrong? So I'm debating whats the best method. I'm aware that catch/blocks should be used in exceptional cases but what if it saves me from having 4 nested if/else conditions? The following is code for an xbox registration site Code: [Select] try { // check code is valid $c1 = $this->input->post('code1',true); $c2 = $this->input->post('code2',true); $c3 = $this->input->post('code3',true); $gt = $this->input->post('gamertag',true); $pass = $this->input->post('password',true); if( $c1 == '' || $c2 == '' || $c3 == '') { throw new FormError("Authorization code invalid."); } // check db for code validation $q = $this->db->query("select * from `codes` where `activated` = 0 and `code` = ".$c1.$c2.$c3." limit 0,1"); if($q->num_rows() != 1) { throw new FormError("Authorization code invalid."); } $r = $q->row_array(); $email = $r["recipient_email"]; $codeGt = $r["gamertag"]; // check valid gamertag $q = $this->db->query("select * from `users` where `gamertag` = '".$gt."'"); if($q->num_rows() > 0) { throw new FormError("Gamertag already exists."); } // validate gamertag /w inputted gamertag if(strtolower($codeGt) != strtolower($gt)) { throw new FormError("Gamertag Invalid"); } $this->_createAccount($email,$pass,$gt); // show register-thanks screen $this->load->view("register-thanks",$data); $success = true; } catch (Exception $e) { $data['error'] = $e->getMessage(); } Hello, So I am trying to reduce my memory footprint to the lowest possible value without sacrificing functionality. I noticed that if I write a comment that is 2kb long, it costs me 2kb more memory to run the script. How can I get PHP to free the memory taken up by comments? It seems like it would be a real pain in the butt to have to run php -w on all my source files each time I update my server. Any ideas? Thanks. David I have searched a lot but no information about this aspect. I wonder how much heavy is the process of getting parts of a webpage by preg_match? But my question is that which of these options are in favor of lighter CPU process: 1. getting each item between specified tags by a preg_match or 2. First getting the content between <body>, then processing by php tools such as preg_match (again), explode, etc. Thanks for considering this unusual question I have some simple test code: Code: [Select] echo memory_get_usage(true); echo("\n" . '<br />' . "\n"); echo memory_get_usage(false); echo("\n" . '<br />' . "\n"); echo memory_get_peak_usage(); that prints out the three types of memory usage in bytes for my basic admin page. All three values are around 2.25 MB in bytes. What's best practice for PHP memory usage? Is 2.25MB far too much for a single user's visit? Do these PHP memory values include images in the page?

I came across something peculiar, and I'm trying to figure out why I get results as I do. Here is my test file: <?php $string_parts = 4; $max = 10000; $arr = array(); $i = 0; $start = memory_get_usage(); for(;$i<$max;$i++){ $arr[] = array_pad(array(), 4, "A"); } $end = memory_get_usage(); printf("%d iterations, %d bytes in array\n", $max, $end-$start); $arr2 = array(); $i = 0; $start2 = memory_get_usage(); for(;$i<$max;$i++){ $arr2[] = array("A", "A", "A", "A"); } $end2 = memory_get_usage(); printf("%d iterations, %d bytes in array (%.2f%%)\n", $max, $end2-$start2, ($end2-$start2)/($end-$start)*100); ?> Output on my system: Code: [Select] 10000 iterations, 4145696 bytes in array 10000 iterations, 5585744 bytes in array (134.74%) A 35% memory gain for two of the same exact arrays seems really weird. Any information as to why, or perhaps any useful functions or resources would be appreciated.

first of all:; i hope youre all right and everything goes well at your site;: Worpress-Plugin API - giving back the meta-data according the usage of different filters
I'm currently working on a parser to make a small preview on the newest plugins in wordpress. at the moment i think i work from a URL given out of the range of these: https://de.wordpress.org/plugins/browse/popular/ - let us say the first 30 to 40 URL-pages.
What i subsequently want to filter out after the fetch is - those plugins that have the newest timestamp Version: 1.9.5.12 installations: 10,000+ WordPress Version: 5.0 or higher Tested up to: 5.4 PHP Version: 5.6 or higher Tags 3 Tags: database member sign-up form volunteer Last updated: 19 hours ago plugin-ratings

what do you say-!? Hey guys, I can't wrap my head around how to make this work right... I have three tables: Code: [Select] CREATE TABLE `games` ( `g_id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(150) DEFAULT NULL, PRIMARY KEY (`g_id`)); CREATE TABLE IF NOT EXISTS `game_player` ( `r_id` int(11) NOT NULL AUTO_INCREMENT, `p_id` int(11) DEFAULT NULL, `g_id` int(11) DEFAULT NULL, `bool` int(1) NOT NULL DEFAULT '0', PRIMARY KEY (`r_id`)); CREATE TABLE IF NOT EXISTS `players` ( `p_id` int(11) NOT NULL AUTO_INCREMENT, `playerid` varchar(150) NOT NULL, PRIMARY KEY (`p_id`), UNIQUE KEY `playerid` (`playerid`)); The players table is my list of users, and they're tied to the list of games via the game_player table. So here's my issue... I'm trying to show the full list of games, and then check mark each record where the player does play it. This is what I have so far - it shows all the games, but it's not checking the boxes. Code: [Select] $result = mysql_query("SELECT * FROM games") or die(mysql_error()); while($row = mysql_fetch_array($result)) { $newquery = "SELECT * FROM game_player, players WHERE game_player.p_id = players.p_id AND game_player.g_id = ".$row['g_id']. " AND players.playerid = {$userid}"; $query = mysql_query($newquery) or die(mysql_error()); if($query['bool'] == 1) { $set_checked = " CHECKED"; } else{ $set_checked = ""; } echo "<input type=\"checkbox\" name=\"box1\" value=\"".$query['g_id']."\"" . $set_checked . "/>".$row['name']."<br />\n"; } Hi, I'm having to look hard for the right way to do this. Basically the image is sent to the database, and is called to be put in a table, but the images are all different sizes, i would like them all one size, whats the best way to do this with my existing script: Code: [Select] <?php error_reporting(E_ALL); ini_set("display_errors", 1); echo '<pre>' . print_r($_FILES, true) . '</pre>'; //This is the directory where images will be saved $target = "/home/users/web/b109/ipg.removalspacecom/images/COMPANIES"; $target = $target . basename( $_FILES['upload']['name']); //This gets all the other information from the form $company_name=$_POST['company_name']; $basicpackage_description=$_POST['basicpackage_description']; $location=$_POST['location']; $postcode=$_POST['postcode']; $upload=($_FILES['upload']['name']); // Connects to your Database mysql_connect("***", "***", "***") or die(mysql_error()) ; mysql_select_db("***") or die(mysql_error()) ; //Writes the information to the database mysql_query("INSERT INTO `Companies` (company_name, basicpackage_description, location, postcode, upload) VALUES ('$company_name', '$basicpackage_description', '$location', '$postcode', '$upload')") ; echo mysql_error(); //Writes the photo to the server if(move_uploaded_file($_FILES['upload']['tmp_name'], $target)) { //Tells you if its all ok echo "The file ". basename( $_FILES['upload']['name']). " has been uploaded, and your information has been added to the directory"; } else { //Gives and error if its not echo "Sorry, there was a problem uploading your file."; } ?> The below code inserts image details to db and uploads pic to folder, can anyone show me how to resize it aswell. please Code: [Select] <?php include("includes/connection.php"); // Where the file is going to be placed $schoolimage = "SchoolImages/"; //This path will be stored in the database as it does not contain the filename $currentdir = getcwd(); $path = $currentdir .
