Linode is a popular Virtual Private Server (VPS) service provider which provides quality linux VPS services at affordable prices. Linode allows programmers to create domain name entries in the Domain manager using a language of your choice via their API. This article describes how domains can be created programatically using PHP.
To use Linode API:
A user must have a Linode account to use the Api. A user can only perform the operations and actions on instances they have access.
User.GetAPIKey() can be used to acquire or generate a user’s API key through the API itself.
The API key can also be generated or regenerated any time via users profile page in linode site.
API Request format:
api_action – This parameter is a must to all requests.
domain.list – specifies the api method which the user wants
The last part of the url specifies the parameters needed for the execution of the method.
There can also be an optional parameter with the request: api_responseFormat.
In the above request the method to execute is domain.list and the parameter passes is the domain id.
API response format:
The optional parameter api_responseFormat can be set to either “json”, “wddx” or “human”.
The default is to output responses in JSON format.
Multiple Requests
The api supports supplying multiple requests that gives an array of responses.The format is
Some api methods with php code samples:
This methods create a domain record.
<?php
function add_linode_domain($domain, $sitesSubDomain, $api_key){
$json_url = "https://api.linode.com/?api_key=$api_key&api_action=domain.create&Domain=$domain&Type=master&SOA_Email=youremail@anydomain.com";
$json = file_get_contents($json_url,0,null,null);
$json_output = json_decode($json);
if(count($json_output->ERRORARRAY) > 0)
return 0;
else{
return $jsonOutputList->DATA->DomainID; //Returns the id of newly created domain record.
}
}
?>
<?php
function add_linode_arecord($domain_id, $sub_domain, $target, $api_key){
$url_add = "https://api.linode.com/?api_key=".$api_key."&api_action=domain.resource.create&DomainID=$domain_id&Type=A&Target=$target&Name=$sub_domain";
$json_file = file_get_contents($url_add,0,null,null);
$json_file_output = json_decode($json_file);
if(count($json_file_output->ERRORARRAY) DATA->ResourceID;//returns a unique resource id of the new added item.
}else
return 0;
}
}
?>
This method deletes a resource
<?php
function delete_linode_subdomain($domain_id, $resource_id, $api_key, $target){
$url_del = "https://api.linode.com/?api_key=".$api_key."&api_action=domain.resource.delete&DomainID=$domain_id&ResourceID=$resource_id";
$json_file = file_get_contents($url_del, 0, null, null);
$json_file_output = json_decode($json_file);
if(count($json_file_output->ERRORARRAY) DATA->ResourceID;
}else
return 0;
}
?>
This returns the list of resources of a particular domain.
<?php
function list_linode_subdomains($domain_id, $api_key){
$json_url = "https://api.linode.com/?api_key=$api_key&api_action=domain.resource.list&DomainID=$domain_id";
$json_file = file_get_contents($json_url,0,null,null);
$json_output = json_decode($json_file);
if(count($json_output->ERRORARRAY) > 0)
return 0;//return zero if the result is an error
foreach ( $json_output->DATA as $data ){
print_r($data);
}
return 0;
}
?>

Using FFmpeg , a complete, cross-platform solution to record, convert and stream audio and video , Cabot developed a unique solution to create Video Gallery using PHP and JQuery.
Features of this tool are:
1. Users can directly upload the video files to a folder on the web server using any FTP client software
2. Thumbnails for the video files are automatically generated by the tool by reading the video file format.
3. It converts video files of type s.avi, .wmv, .mov, .qt, mpg or .rm into flv.
A demo of this video gallery can be found here:
Minimum Requirements
1. The tool works only on a Dedicated Hosting Server in Linux
2. FFMPEG should be installed and configured.
FFMPEG can be downloaded and installed from here.
Source Code:

Cabot Solutions was approached by Sunny South Insulators, to build an integrated web based CRM application to help manage their client contacts, project estimates, scheduling, invoices and calendar modules. The application was to assist the firm to effectively streamline and manage its business processes.
Mathematical Markup Language (MathML) describes mathematical notations and capturing both its structure and content. The objective of mathml is to integrate mathematical formulae into World Wide Web documents.
For examples of mathematical expressions and the syntax for writing them within a wiki refer
http://meta.wikimedia.org/wiki/Help:Formula
Example:<math>$ {x}^{2}+4x+4=0$</math> represents the expression 
To setup mathml support in mediawiki, we have to install several modules in the server. Please find the steps to make it work below.
1.Setup Tex proccessing in LocalSettings.php
Open the file LocalSettings.php and enable tex processing. This can be achieved by setting $wgUseTeX = true;
2. Install texvc
The mediawiki application by default comes with the source code for texvc in /mediawiki/math. To install this, we can follow any one of the options below.
3. Install TeTeX (http://www.tug.org/teTeX/)
4. Install Ghostscript (http://www.ghostscript.com/)
5. Install ImageMagick (http://www.imagemagick.org/)
6. Install AMS fonts (http://www.ams.org)
Please make sure that latex, dvips, convert and gs are installed.
To know whether these modules are installed and the path, use the commands “which latex” , “which dvips” etc in the console.
7. Install libstdc++5(sudo apt-get install libstdc++5)
8. Please make sure the Ghostscript and ImageMagick do not have conflicting versions.
9. PNG files for mathematical expressions are stored in the math directory. Please check the subdirectories math and tmp in the upload subdirectory to see their contents. Sometimes if the
conversion process ceases or has any issue in certain stage, files of that type may remain in the tmp directory only.
Url shortening is a technique in which a larger URL is made available by accessing a relatively shorter URL. This is useful for sending links with via email, twitter, sms etc. Popular URL shortening services include tinyurl.com and bit.ly.
Usually, the long web page url is mapped to a randomly generated string-numeric combination such that by typing the
url http://shorteningservice.com/randomstring will redirect to the original long url.
I have made the generation of random strings in a uniform way using php by using the characters A to Z.
This is explained below (Usage Examples: 2). This method provides the user a chance to predict the next short url.
permutations(”ABCDEF”, 3) will return an array of 130 string sequences from ABC to DEF.
This is the permutation of 6 charecters taken 3 at a time. Here ABC and ACB are taken as seperate entities.
That is a sequence of the form AAA, AAB, …., ZZZ, AAAA,AAAB,AAAC,…ZZZZ,…..,ZZZZZZZZZZ…ZZ.
I can show you a function that returns the next element of the above series when the current string is given.
<?php
//function to get the array permutation string sequences
function stringPermute($orgString,$num){
$last = substr($orgString, 0, $num);
$result = array();
while($last != substr($orgString, -$num)){
$result[] = $last;
$last = getNextString($orgString,$last,$num-1);
}
$result[] = $last;
return $result;
}
//Function to get the next string sequence in order
function getNextString($fullString,$string,$char){
if($string{$char} <> lastElement($fullString)){
$string{$char} = $fullString{strpos($fullString,$string{$char})+1};
return $string;
}else{
$string = change($string,$fullString{0},$char);
return getNextString($fullString,$string,$char-1);
}
}
function lastElement($string){
return $string{strlen($string)-1};
}
function change($string,$char,$start = 0,$end = 0){
if($end == 0)
$end = strlen($string)-1;
for($i=$start;$i<=$end;$i++){
$string{$i} = $char;
}
return $string;
}
?>
