Is there a way to know how much Internet connection speed someone has with PHP? I've seen a lot that a site says whether you have a good connection or not, like live.chess.com? (Actually its accurate)
How to know it with PHP?
This is not a trivial task to do. You have to consider many other factors that may slow down the connection, such as work load on your server etc.
If you just want to know whether the connection between your server and your user is good or not, you could use something like timing page load from a javascript, or so. You could use ping time, but that result wouldn't always represent the truth, since there might be a proxy / nat between you and the user. With the ajax request way, you still don't have the guarantee results are trustable.
If you need that information for, example, decide which content to show the user (eg. switch between flash/html versions, ..), better way is always to ask the user which one wants to see.
If you just want to show the user how good is his connection, or you need that information to be quite trustful, i'd recommend using an external service (for example, here in Italy I use test.ngi.it), that has everything needed to be (almost) sure measured values are realistic.
Assuming that you wish to stick with PHP, put the following code at the very beginning of your PHP page:
<?
$load_time = microtime();
$load_time = explode(' ',$load_time);
$load_time = $load_time[1] + $load_time[0];
$page_start = $load_time;
?>
Put the following code at the end of your page right before the tags:
<?
$load_time = microtime();
$load_time = explode(' ',$load_time);
$load_time = $load_time[1] + $load_time[0];
$page_end = $load_time;
$final_time = ($page_end - $page_start);
$page_load_time = number_format($final_time, 4, '.', '');
echo("Page generated in " . $page_load_time . " seconds");
?>
The load time will be displayed.

I am trying to get a reply text message from Clickatell using their Rest API, when I call the parseReplyCallback function when their system posts to my page - it seems to be null or I am not sure how to get the variables it is returning. What I would like to do is have all of the variables returned insert into a SQL database so I can use it elsewhere.
I have tried quite a few things, using various styles of getting the variables such as $_POST, $results['text'], $results->text, and so forth each time I can't seem to get any information out of it. I can't just var_dump or anything because I can't see any backend or console so I am pretty much in the blind, hoping someone else is using this system and has it working fine.
require __DIR__.'/clickatell/src/Rest.php';
use clickatell\ClickatellException;
use clickatell\Rest;
$Rest = new Rest("j8VKw3sJTZuVfQGVC7jdhA");
// Incoming traffic callbacks (MO/Two Way callbacks)
$Rest->parseReplyCallback(function ($result) {
//mysqli_query($con,"INSERT INTO `SMSCHAT` (`text`) VALUES ('$result')");
$mesageId = mysqli_real_escape_string($con,$result['messageId']);
$text = mysqli_real_escape_string($con,$result['text']);
$replyMessageId = mysqli_real_escape_string($con,$result['replyMessageId']);
$to = mysqli_real_escape_string($con,$result['toNumber']);
$from = mysqli_real_escape_string($con,$result['fromNumber']);
$charset = mysqli_real_escape_string($con,$result['charset']);
$udh = mysqli_real_escape_string($con,$result['udh']);
$network = mysqli_real_escape_string($con,$result['network']);
$keyword = mysqli_real_escape_string($con,$result['keyword']);
$timestamp = mysqli_real_escape_string($con,$result['timestamp']);
//do mysqli_query
});
I'd like for it to break the result into individual variables (because I plan on doing other things such as an auto-reply, etc) and upload it to the SQL database scrubbed.
Either doesn't create the table entry or gives me a blank one altogether in that first test where I put the result in the text field.
From a Clickatell point of view, although we understand what you're asking - it's unfortunately outside the scope of support that we offer on our products.
If you would like more information on our REST API functionality, please feel free to find it here: https://www.clickatell.com/developers/api-documentation/rest-api-reply-callback/
If you don't succeed in setting up the callbacks, please feel free to log a support ticket here: https://www.clickatell.com/contact/contact-support/ and one of our team members will reach out and try to assist where possible.
I want to build a statistic graph that shows how many users have registered per day and maybe some other data. I have a MySql table in which I store the date they registered and usernames and etc.
How would I build such a graph ? What do I need for it ?
You don't always need to do things using real graphics.
<?php
// mysql connection setup
// ...
// Get the dates in a single SELECT. 2592000 seconds = 30 days
$result = mysql_query("SELECT regdate FROM users WHERE regdate > NOW()-2592000");
foreach ($row = mysql_fetch_row($result)) {
$output[date("Y-m-d", strtotime($row['regdate']))]++;
}
$fmt = ' <tr><td>%s</td><td width="%s" background="#FF0000"> </td></tr>' . "\n";
?>
<table border="0" cellspacing="0" cellpadding="0"><tr height="100">
<?php
for ($date = time()-2592000; $date < time(); date += 86400) {
$thisdate = date("Y-m-d", $date);
printf($fmt, $thisdate, $output[$thisdate]);
}
?>
</tr></table>
?>
Untested, obviously. Possibly incomplete. YMMV. Salt to taste.
There are many ways to build a graph. I can think of a few methods, use one you think best depending on your knowledge.
In every case you need to query your database. So basics of MySQL.
Then you can either create graph on server side by looping trough result set and creating graph by simple HTML divs or using GD library.
Or you can send result set as JSON object and create graph on client side using simple HTML divs or canvas tag.
Server side graphs are much simpler but cant be animated or updated without page refresh. Client side graphs require additional knowledge (JSON, security etc.)
If you only need bar graphs, you might be much better of using divs of a calculated height, all anchored to a bottom line. This is quite trivial to write and uses a whole lot less of CPU, RAM and bandwidht.
Hey guys i'm making a website where you submit a server for advertising. When the user goes to the index page of my website it grabs the ip's of all the servers submitted and then tests to see if it is online using fsockopen() like so:
while($row = mysql_fetch_assoc($rs)) {
$ip = $row['ip'];
$info = #fsockopen($ip, 25565, $errno, $errstr, 0.5);
if($info) {
$status = "<div><img width='32px' height='32px'
title='$name is online!' src='images/online.png'/></div>";
$online = true;
} else {
$status = "<div><img width='32px' height='32px'
title='$name is offline!' src='images/offline.png'/></div>";
$online = false;
}
}
}
This way works fine, but the only downside is when you load the site it takes a good 2-4 seconds to start loading the website due to the fsockopen() methods being called. I want to know if there is a better way to do this that will reduce the amount of wait time before the website loads.
Any information will be appreciated, thanks.
Store the online status and last check time in a database, if the last check time is longer than 15 minutes for example, update it. I am pretty sure you don't need to get the status on EVERY pageload? It's the time it takes to connect to each server that slows down the website.
Then again, you would probably wanna move the update process to a cronjob instead of relying on someone visiting your website to update the server statuses.
Looking at your example, I'd make all the $status bits be javascript calls to another php page that checks that individual server.
However, the idea to move the status checks to cron job or use some kind of status caching is very good too. Maybe store statuses in a database only only check the ones that have expired (time limit set by you).
I am doing this flash banners for multiple clients and one major request is to have some sort of counter so they know how many times the banner has been clicked.
I know how to do it in ActionScript 3.0, I make a simple var:int and i increase it +1 when a click is made on the banner. What do I do with the value of this var(say its 121) where do I store it online so its safe and can be changed by multiple flash banners(as3).
But how do I save this information so next time when the banner is loaded(on diffrent webpages) the number of clicks is whatever it was last time it was loaded.
Should I look into PHP for that ? I have no clue how to do this... some examples, tutorials, whatever works... would be much appreciated.(I am a designer, not programmer...please dont speak php-ish, or you know... :D)
I've googled a bit, and found some help, but i am still confused, and much of it its not AS3, I'm thinking maybe stuff has evolved a bit since the stuff that I found(2008)...
Thank you very much.
You'd have to store (and fetch) the value somewhere - either in the DB, in a text-file, ...
I'd go search for a tutorial on PHP+MySQL. If you don't like PHP-ish, you're probably better of finding another solution though :p
Example tutorial: http://www.freewebmasterhelp.com/tutorials/phpmysql
You need to store the data you want be retrievable/update-able from multiple clients, to be stored on a server.
You can use any server side language with a database.
Server Languages : PHP, ASP.net, JSP, ColdFusion
Database : MySQL, MSSQL, PostgreSQL, Oracle, DB2 etc..
Use whatever combination you are comfortable with.
In general:
You have a web app that increments the counter in the database
call the page using URLLoader from your AS3 banner.
Database
counter_table
-------------
counter INT
PHP File
$db = mysql_connect('localhost', 'mysql_user', 'mysql_password');
mysql_select_db('database_name');
mysql_query('UPDATE counter_table SET counter = counter + 1');
AS3 Banner
// url request with your php page address
var scriptRequest:URLRequest = new URLRequest("http://www.example.com/script.php");
// loader
var scriptLoader:URLLoader = new URLLoader();
// load page to trigger database update
scriptLoader.load(scriptRequest);
Do you also want to retrieve the value of the number of clicks in Banner ?
Easy solution (really not the best :) You should use one of the other answers.. anyways, make a php file that reads txt file containing the count of visits.. and in your flashbanner just call the php file. It'll add one hit per call..
PHP:
<?php
/**
* Create an empty text file called counterlog.txt and
* upload to the same directory as the page you want to
* count hits for.
*
*
* #Flavius Frantz: YOU DONT NEED THESE:
* Add this line of code on your page:
* <?php include "text_file_hit_counter.php"; ?>
*/
// Open the file for reading
$fp = fopen("counterlog.txt", "r");
// Get the existing count
$count = fread($fp, 1024);
// Close the file
fclose($fp);
// Add 1 to the existing count
$count = $count + 1;
// Display the number of hits
// If you don't want to display it, comment out this line
//echo "<p>Page views:" . $count . "</p>";
// Reopen the file and erase the contents
$fp = fopen("counterlog.txt", "w");
// Write the new count to the file
fwrite($fp, $count);
// Close the file
fclose($fp);
?>
Example code from: (google: php counter file) http://www.totallyphp.co.uk/text-file-hit-counter
Code is not tested, but looks ok. I only commented just a little..
I'm trying to get the country from which the user is browsing the website so I can work out what currency to show on the website. I have tried using the GET scripts available from: http://api.hostip.info but they just return XX when I test it.
If anyone knows any better methods please share.
Thanks.
I use this:
$_SESSION['ip'] = $_SERVER['REMOTE_ADDR'];
$ip = $_SESSION['ip'];
$try1 = "http://ipinfodb.com/ip_query.php?ip=".$ip."&output=xml";
$try2 = "http://backup.ipinfodb.com/ip_query.php?ip=".$ip."&output=xml";
$XML = #simplexml_load_file($try1,NULL,TRUE);
if(!$XML) { $XML = #simplexml_load_file($try2,NULL,TRUE); }
if(!$XML) { return false; }
//Retrieve location, set time
if($XML->City=="") { $loc = "Localhost / Unknown"; }
else { $loc = $XML->City.", ".$XML->RegionName.", ".$XML->CountryName; }
$_SESSION['loc'] = $loc;
Try these:
http://ip-to-country.webhosting.info/
http://www.ip2location.com/
Both are IP address-to-country databases, which allow you to look up the country of origin of a given IP address.
However it's important to note that these databases are not 100% accurate. They're a good guide, but you will get false results for a variety of reasons.
Many people use proxying to get around country-specific blocks and filters.
Many IP ranges are assigned to companies with large geographic spread; you'll just get the country where they're based, not where the actual machine is (this always used to be a big problem for tracking AOL users, because they were all apparently living in Virginia)
Control of IP ranges are sometimes transferred between countries, so you may get false results from that (especially for smaller/less well-connected countries)
Keeping your database up-to-date will mitigate some of these issues, but won't resolve them entirely (especially the proxying issue), so you should always allow for the fact that you will get false results.
You should use the geoip library.
Maxmind provides free databases and commercial databases, with a difference in the date of last update and precision, the commercial being of better quality.
See http://www.maxmind.com/app/geolitecountry for the free database.
I think it should be sufficient for basic needs.
You can use Geolocation to get the Coordinates and then some Service to get the Country from that, but the geolocation API is browser based so you can only access it via JavaScript and then have to pass theese Informations to PHP somehow, i wrote something on the JS Part once:
http://www.lautr.com/utilizing-html5-geolocation-api-and-yahoo-placefinder-example
When it comes to getting the Location via the IP, there are a bazillion Services out there who offer databases for that, some free, some for charge, some with a lot of IP's stored and much data, some with less, for example the one you mentioned, works just fine:
http://api.hostip.info/?ip=192.0.32.10
So You can ether go with the Geolocation API which is pretty neat, but requires the users permission, works via JS and doesnt work in IE (so far) or have to look for a IPÜ Location Service that fits your needs :)
Try these:
$key="9dcde915a1a065fbaf14165f00fcc0461b8d0a6b43889614e8acdb8343e2cf15";
$ip= "198.168.1230.122";
$url = "http://api.ipinfodb.com/v3/ip-city/?key=$key&ip=$ip&format=xml";
// load xml file
$xml = simplexml_load_file($url);
// print the name of the first element
echo $xml->getName() . "";
// create a loop to print the element name and data for each node
foreach($xml->children() as $child)
{
echo $child->getName() . ": " . $child . "<br />";
}
There are many ways to do it as suggested by those earlier. But I suggest you take a look at the IP2 PHP library available at https://github.com/ip2iq/ip2-lib-php which we developed.
You can use it like below:
<?php
require_once("Ip2.php");
$ip2 = new \ip2iq\Ip2();
$country_code = $ip2->country('8.8.8.8');
//$country_code === 'US'
?>
It doesn't need any SQL or web service lookup just a local data file. It is faster than almost all other methods out there. The database is updated monthly you can download it for free.
The only thing you will need to do for now if you need the country name in your language is map it to an associative array from something like this https://gist.github.com/DHS/1340150
