PHP - Calculate The User's Internet Speed?

Since I got my websocket PHP server running nicely with my MYSQL, I can now have some fun   Attack speed is very simple, but I need your help with the unixtimestamp.   For example, There is a field name called "last_attack" and each time a user attacks a mob and a skill was performed; it will be updated with:

time();

Then I disable the attack button for 2 seconds client side, but I also check that value against time() serverside as well.   Now let's say the user's attack speed is 1.30%   I want to make that Attack Speed check, to check it dynamically.   It should now check only if the attack was less than 1.7 seconds ago instead of 2 seconds. How do I split up the unixtimestamp to work with percents?

Iv'e been looking in to methods of scraping data from pages and has found several examples of using multi-curl to achieve this. But i am not used to curl and is not completely sure how it works and i need to find the fastest reliable (i do need all, or close to all, pages every run) method of getting the content of a number of pages (about 160).

Here is an example i got from searching the web which i managed to implement:
<?php 
/** 
 * 
 *@param $picsArr Array [0]=> [url], 
 *@$picsArr Array will filled with the image data &#65292; you can use the data as you want or just save it in the next step. 
 **/ 

function getAllPics(&$picsArr){ 

        if(count($picsArr)<=0) return false; 

        $hArr = array();//handle array 

        foreach($picsArr as $k=>$pic){ 

                $h = curl_init(); 
                curl_setopt($h,CURLOPT_URL,$pic['url']); 
                curl_setopt($h,CURLOPT_HEADER,0); 
                curl_setopt($h,CURLOPT_RETURNTRANSFER,1);//return the image value 

                array_push($hArr,$h); 
        } 

        $mh = curl_multi_init(); 
        foreach($hArr as $k => $h)      curl_multi_add_handle($mh,$h); 

        $running = null; 
        do{ 
                curl_multi_exec($mh,$running); 
        }while($running > 0); 

        // get the result and save it in the result ARRAY 
        foreach($hArr as $k => $h){ 
                $picsArr[$k]['data'] = curl_multi_getcontent($h); 
        } 

        //close all the connections 
        foreach($hArr as $k => $h){ 
                $info = curl_getinfo($h); 
                preg_match("/^image\/(.*)$/",$info['content_type'],$matches); 
                echo $tail = $matches[1]; 
                curl_multi_remove_handle($mh,$h); 
        } 
        curl_multi_close($mh); 

        return true; 
} 
?> 


Since time is critical in my script i would ask if you think this is a good implementation or if you can point me in the direction of one that will save me noticeable run-time.

Complete beginner here so just really looking for pointers on where to start.

Been doing a bit of bug fixing on one of our sites because the past 3 programmers we've hired have disappeared on us. The big issue I'm looking to solve is the load time of a search. Our website (Love-Rugs) is taking about 6 or 7 seconds to perform a blank search (basically a quick browse) whereas out other site (Little-Persia) takes about a second. It wouldn't be so bad if it was just the initial search but going from one page (only 10 products listed per page) to the next takes the same amount of time.

There seems to be an awful lot of queries (around 130-150) on the searches - however - when using some of the search options e.g. type and fabric to refine the search the queries actually stay high but the time to process the results is reduced significantly. I don't really understand why if the queries are still high the search time is much lower unless it's to do with the number of results returned. However this does not explain why Little-Persia (which has far more products on it) takes less time as there would obviously be more results.

I realize that without code this isn't easy to answer so I'm just looking to see if someone can point me in the right direction to look at just now.

Is there any php function I can test how fast my server is performing, like how fast its carrying out a certain action so I can see its resource usage.

I am currently using PHP 5.3.2 on IIS 7 and I am wondering how can I write a download script with resume and speed limit. After looking for a while, I found this script that works on speed limit:
Code: [Select]
<?php
$local_file = 'file.zip';
$download_file = 'name.zip';

// set the download rate limit (=> 20,5 kb/s)
$download_rate = 20.5;
if(file_exists($local_file) && is_file($local_file))
{
    header('Cache-control: private');
    header('Content-Type: application/octet-stream');
    header('Content-Length: '.filesize($local_file));
    header('Content-Disposition: filename='.$download_file);

    flush();
    $file = fopen($local_file, "r");
    while(!feof($file))
    {
        // send the current file part to the browser
        print fread($file, round($download_rate * 1024));
        // flush the content to the browser
        flush();
        // sleep one second
        sleep(1);
    }
    fclose($file);}
else {
    die('Error: The file '.$local_file.' does not exist!');
}

?>
Though there is a big problem that the download file comes without extension. For example if the original file is file.ext then the client will receive it as file without any extension. I just want to use octet-stream since I have no interest in streaming or other things, but I really want the client to have the extension also.

So could you please tell me what is wrong with the above script, and please show me a way to do resume download. Thank you very much for your help.

Okay I have a function that stores data into an Array.  The function takes about 7 seconds to run and through a number of different loops it creates one final array with about 15,000 keys.  I want to recall this data a number of times in different functions, however how can I have this data easily accessible without running the function each time.

EX:
Code: [Select]
function theFunction()
{
   for($x=0;$x,=15000;$x++)
   {
   //Run the loop and store data.
   $string[$x] = //output from other loops and calculations
   }
   return $string
}

//Then later on if I want to recall the data the only way I know how is to do the follow:
$newstring = theFunction()

The only problem I have with this is that it has to re-run the function every time in order to get to the data it spits out.  How can I store this data into another array outside of the function without having to re-run it?

I hope this makes sense.

Thanks.

I am writing an OO PHP app to parse thousands of frames from a film, which will then each be manipulated and spat out using GD library funcs. Speed is of the essence.

To improve speed, I have considered:

- Another language!?
- Use of PHP Command Line Interface? ( Working with web browser is surely a slow affair?)

If PHP was a standard R6 Yamaha available to Joe Public, what would I have to do to win a GP race - you know - change gearing, alter timing, change exhaust system, rip out the air filter 

What does the panel suggest?

Thanks

hello dear community,

i am currently wroking on a approach to parse some sites that contain datas on Foundations in Switzerland
with some details like goals, contact-E-Mail and the like,,,

See http://www.foundationfinder.ch/  which has a dataset of 790 foundations. All the data are free to use - with no limitations copyrights on it.

I have tried it with PHP Simple HTML DOM Parser - but , i have seen that it is difficult to get all necessary data -that is needed to get it up and running.

Who is wanting to jump in and help in creating this scraper/parser.   I love to hear from you.

Please help me - to get up to speed with this approach?


regards

I have a table called "playlists", and a table called "musics". In the musics table, there is a column playlist_id which references the playlist that each music is contained.   I'm using api calls to display information on the site with JavaScript, so I need to return a JSON.   I need the json with the following structu   [   Playlists: [                   {                     Name: "etc",                     musics: [                                    {                                      name: "teste.mp3"
                                  },                                   {                                      name: "test2.mp3"                                    }                                  ]                      },                      ...                  ] ]   And this is my code:    $query = $con->prepare("SELECT * FROM playlists WHERE user_id = :id");

I would appreciate your assistance, there are tons of login scripts and they work just fine. However I need my operators to login and then list their activities for the other operators who are logged in to see and if desired send their clients on the desired activity. I have the login working like a charm and the activities are listed just beautifully. How do I combine the two tables in the MySQL with PHP so the operator Logged in can only make changes to his listing but see the others.

FIRST THE ONE script the member logges in here to the one table in MSQL:
<?php
   session_start();
   
   require_once('config.php');
   
   $errmsg_arr = array();
   
   $errflag = false;
   
   $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
   if(!$link) {
      die('Failed to connect to server: ' . mysql_error());
   }
   
   $db = mysql_select_db(DB_DATABASE);
   if(!$db) {
      die("Unable to select database");
   }
   
   function clean($str) {
      $str = @trim($str);
      if(get_magic_quotes_gpc()) {
         $str = stripslashes($str);
      }
      return mysql_real_escape_string($str);
   }
   
   $login = clean($_POST['login']);
   $password = clean($_POST['password']);
   
   if($login == '') {
      $errmsg_arr[] = 'Login ID missing';
      $errflag = true;
   }
   if($password == '') {
      $errmsg_arr[] = 'Password missing';
      $errflag = true;
   }
   
   if($errflag) {
      $_SESSION['ERRMSG_ARR'] = $errmsg_arr;
      session_write_close();
      header("location: login-form.php");
      exit();
   }
   
   $qry="SELECT * FROM members WHERE login='$login' AND passwd='".md5($_POST['password'])."'";
   $result=mysql_query($qry);
   
   if($result) {
      if(mysql_num_rows($result) == 1) {
         session_regenerate_id();
         $member = mysql_fetch_assoc($result);
         $_SESSION['SESS_MEMBER_ID'] = $member['member_id'];
         $_SESSION['SESS_FIRST_NAME'] = $member['firstname'];
         $_SESSION['SESS_LAST_NAME'] = $member['lastname'];
         session_write_close();
         header("location: member-index.php");
         exit();
      }else {
         header("location: login-failed.php");
         exit();
      }
   }else {
      die("Query failed");
   }
?>

Now I need the person who logged in to the table above to be able to make multiple entries to the table below

<?
$ID=$_POST['ID'];
$title=$_POST['title'];
$cost=$_POST['cost'];
$activity=$_POST['activity'];
$ayear=$_POST['aday'];
$aday=$_POST['ayear'];
$seats=$_POST['special'];
$special=$_POST['seats'];
mysql_connect("xxxxxx", "xxx350234427", "========") or die(mysql_error());
mysql_select_db("xxxx") or die(mysql_error());
mysql_query("INSERT INTO `activity` VALUES ('ID','$title', '$cost','$activity', '$aday', '$ayear', '$special', '$seats')");
Print "Your information has been successfully added to the database!"
?>
Click <a href="member-profile.php">HERE</a> to return to the main menu

hi,

i have made a website where people resgister their details of them and products.

they have to enter the following details in form

Name of company

name of the product

company address

email id 

password 

mobile number contact

and 

brief details about their company 

after filling all details user is registered on website.

user can then login with email id and pwd.

now after login ..user will get a page where he can upload the photos of products images and their price, so now my question is that when he finishes uploading (|by clicking on upload button) the product images and price text box ..then on final uploaded webspage it should show all other things which he registerd before (company name , mobile number etc) along with images and price...hence the main question that user does not need to enter mobile and address while uploading images and filling proce ..but on the final page it should show mobile and address along with price and images..as user is not going to enter mobile and address again and again as he will have multiple products to upload.

thanks in advance .

Hi,

so far I have managed to set up a somewhat basic login website with a mysql database backend.

Once they have logged on they go to a "main menu" page.

What I need to define is that user A sees button A but only that button, etc.

(Then of course that same rule would have to apply if they tried to directly go to the page, but I am guessing I can do that in the same way that I currently do to force a login).

If anyone has any tutorials or sample code I would much appreciate it.

Thanks,

Actually, what i want to do is to use the email to fetch the $email,$password and $randomnumber from database after

Hi,

I am getting frustrated beyond belief at the moment with trying to get a very simple script to run, I am using PHP 5.3.3 and MySQL 5.1 on a Win2k8 server with IIS7.5. Basically my script is connecting to a local database, running a single select query, returning those rows and building up a string from them.

The problem is that I am receiving complete BS responses from PHP that the access is denied for the user being specified. This is complete rubbish since the user can connect via mysql, sqlyog, ASP.NET MVC without issue but for some bizarre reason it is not working via PHP.

The code for the script is here :

Code: [Select]
<?php

$mysql = mysql_connect('127.0.0.1:3306', 'myuser', 'mypass', 'mydatabase');


if (!$mysql) {
  die(mysql_error());
  $content = "<nobr></nobr>";
} else {
  
  $result = mysql_query('SELECT * FROM tblEventGroup'); 
  $content = "<nobr>";
  
  if ($result) {     
      while($row = mysql_fetch_assoc($result)) {
       $content .= "<span>";
       $content .= $row['GroupName'];
       $content .= "</span>";
       $content .= "<a href=\"../Event/EventSearch?groupid=";
       $content .= $row['GroupId'];
       $content .= "\" target=\"_blank\">Book here</a> ";
      }
  }
  
  mysql_close($mysql);
  $content .= "</nobr>";

}

?>
I cannot for the life of me understand what the problem is, the return error is

Access denied for user 'myuser'@'localhost' (using password: YES)

Hi guys,

I am trying to put together a little system that allows users to log onto my website and access there own personal page. I am creating each page myself and uploading content specific to them which cannot be viewed by anyone else.

I have got the system to work up as far as:

1/ The user logs in
2/ Once logged in they are re-directed to their own page using 'theirusername.php'

Thats all good and working how I need it too. The problem I have is this. If I log onto the website using USER A details - I get taken to USER A's page like I should but - If I then go to my browser and type in USERBdetails.php I can then access USER B's page.

This cannot happen!! I need for USER A not to be able to access USER B profile - there is obviously no point in the login otherwise! If you are not logged in you obviously cannot access any secure page. That much is working!

Please find below the code I am using:


LOGIN

<?php
session_start();


function dbconnect()
{
    $link = mysql_connect("localhost", "username", "password") or die ("Error: ".mysql_error());

}
?>

<?php
if(isset($_SESSION['loggedin']))
{
    header("Location:" . strtolower($username) . ".php");
if(isset($_POST['submit']))
{
   $username = mysql_real_escape_string($_POST['username']);
   $password = mysql_real_escape_string($_POST['password']);
   $mysql = mysql_query("SELECT * FROM clients WHERE username = '{$username}' AND password = '{$password}'");
   if(mysql_num_rows($mysql) < 1)
   {
     die("Password or Username incorrect! Please <a href='login.php'>click here</a> to try again");
   }   $_SESSION['loggedin'] = "YES";
   $_SESSION['username'] = $username;
 $_SESSION['name']
   header("Location:" . strtolower($username) . ".php");
}
?> 

HEADER ON EACH PHP PAGE

<?php
session_start();
if(!isset($_SESSION['loggedin']))
{
    die(Access to this page is restricted without a valid username and password);
?>

---------------------------------------------------

Am I right in thinking it is something to do with the "loggedin" part?

The system I have here is adapted from a normal login system I have been using for years. The original just checks the details and then does a 'session start'. This one obviously has to re-direct to a user specific page. To do this I used the <<header("Location:" . strtolower($username) . ".php");>> line to redirect to a page such as "usera.php" or "userb.php"

Any help would be greatly appreciated!
