Why Hire PHP Developers for High Quality Web App Development

Posted on by Mandakinee

PHP is a widely-used Open Source, general-purpose, cross-platform & HTML embedded server-side scripting language, that suits web development.

PHP Framework is a fundamental platform that helps programmers for rapid and effective development. It’s one of the powerful tool which helps to tweak code in a standard configured manner & can be used with many relational database management systems (RDBMS).

Reasons of Choosing PHP scripting language

Simple and Easy To Learn

PHP is one of the easiest scripting language to learn and understandable by developers. The syntax is somewhat similar to Java and C. However, knowledge of HTML is the only prerequisite to code in PHP.

Instant Support

When a developer stuck with any coding issue, there are huge numbers of references, forums and support communities available online and they are free. This is simply because, PHP is very popular, widely used and having the largest user base.

Supports All Major OS

PHP can be run on top of major operating systems such as Windows, Linux, UNIX, Mac OSX and so on.

Free of Cost

PHP is an open source and 100% Free for use by anyone. This cuts down cost of production as well as hosting. For these reasons it enjoys popularity over other expensive scripting languages such as ASP, JSP and others.

Integration

PHP makes developers life easy as it can be integrated easily with any of the systems like MongoDB, Memcache, Pusher and more. More or less PHP applications can cater any verticals such as banking sectors, health/hospital industry, government sector or corporates and so on.

Frameworks

PHP developers can develop robust application within a very short time frame using a variety of frameworks like Symfony, Slim, Silex, Zend and Aiki. Each framework allows you to avail a set of benefits including code reuse, better session management and database access libraries.

Easier to fix problems

It is obvious that the web application development is not free from issues, however with PHP it is comparatively easier to troubleshoot than it’s counterparts. This is because with each request, PHP cleans up and starts over. So issue with one request does not affect another request.

Scalability

Scalability is always in demand be it for databases, hosting, or programming, scalability. PHP is built in such a way that you can easily increase your cluster size with grow of your projects.

Object Oriented

Java and Windows COM objects can be called called from PHP. Also PHP allows to create custom classes which in turn can be borrowed by other classes. This is one of the useful capabilities of PHP.

Speed

PHP does not take lot of system resource and operates much faster than other scripting languages. PHP maintains its speed even if it is used with other software. Since PHP is out for a long time, continuous effort is on to make it even better. As a result of which it is fairly stable compared to it’s counterparts.

How To Generate PDF File In CakePHP

Posted on by Anurag Pattnaik

TCPDF is a free and open source software one of the widely used PHP libraries in the world. This is because of the fact that it already included in the most popular PHP-based CMS and applications including CakePHPHow to generate pdf file in cakephp.

The installation is pretty straight forward and easy-to-use in CakePHP Framework. Many web applications use this as output documents like invoices, contracts or just web pages in the PDF format.

 

Following are the steps to integrate TCPDF in CakePHP MVC framework.

Step 1:

  • Go to http://www.tcpdf.org and download the latest version of TCPDF zip file.
  • Then unzip the zip file and save under the Vendor folder in cakephp framework(app\vendors)
  • This creates a directory tcpdf there with tcpdf.php and more in it (app\vendors\tcpdf)
  •  You can configure the PDF file Like header Logo Image, Page Title, page Margin etc. in the TCPDF configure file (app->vendors->tcpdf-> tcpdf_config.php)

Step 2:

You can create your own header and footer page of your PDF file. Create a page “xtcpdf.php” under app/vendors with these contents as shown below.

App::import('Vendor','tcpdf/tcpdf');
class XTCPDF extends TCPDF
{
var $xheadertext = 'PDF created using CakePHP and TCPDF';
var $xheadercolor = array(0,0,200);
var $xfootertext = 'Copyright © %d XXXXXXXXXXX. All rights reserved.';
var $xfooterfont = PDF_FONT_NAME_MAIN ;
var $xfooterfontsize = 8 ;
/* Change header text and font size as per your requirement in the above variable*******/
function Header()
{
list($r, $b, $g) = $this->xheadercolor;
$this->setY(10); // shouldn't be needed due to page margin, but helas, otherwise it's at the page top
$this->SetFillColor($r, $b, $g);
$this->SetTextColor(0 , 0, 0);
$this->Cell(0,20, '', 0,1,'C', 1);
$this->Text(15,26,$this->xheadertext );
}
function Footer()
{
$year = date('Y');
$footertext = sprintf($this->xfootertext, $year);
$this->SetY(-20);
$this->SetTextColor(0, 0, 0);
$this->SetFont($this->xfooterfont,'',$this->xfooterfontsize);
$this->Cell(0,8, $footertext,'T',1,'C');
}
}
?>

Step 3:

Create your layout under app/views/layouts/pdf.ctp;

header("Content-type: application/pdf");
echo $content_for_layout;
?>

Step 4:

Here is the Controller code which will display output code of generating PDF file;

function view_pdf($id = null) {
if (!$id) {
$this->Session->setFlash('Sorry, there was no PDF selected.');
$this->redirect(array('action'=>'index'), null, true);
}
$this->layout = 'pdf'; //this will use the pdf.ctp layout
$this->render();
}

Step 5:

Create a page under your view directory (app/views/) named as “view_pdf.ctp” (this name can be change as per your controller method) and write your HTML code/PHP code.

How To Implement Security Patches On Ruby On Rails Applications

Posted on by Ajay Sahoo

The security of any software product or application is something that every software solution provider is wary of. It is no different in the case of a Ruby on Rails application.

Even after an application is successfully developed and deployed, there can be possibilities for many unseemly activities.

US-based high-end software solution provider Andolasoft.Inc sheds some light on some of the basic precautions that are worked upon before deploying an application.

The Company’s Ruby on Rails developers pay special attention to security issues in every undertaken venture.
Authentication and authorization of the User model are two different things.

Never miss an update from us. Join 10,000+ marketers and leaders.

Actions like create/update/delete always need to be protected. Even popular plug-ins like Restful authentication and Clearance only authenticate whereas providing no helper methods for authorization.

Mass assignment of sensitive attributes from re-assignment should be protected.

This can be taken care of by disabling mass assignment with the help of attr_accessible or attr_protected in the respective models. Attributes like account_id’s and user_id’ should be protected.

Also disabling updates on protected attributes can be by using attr_readonly so that the Ids don’t get updated once set.

Content types of files being uploaded can be faked, so uploaded files should be placed in protected directories or servers.

Also, file extensions should be checked and the web-server should be disabled so as not to execute such files in the uploaded directories.

Sessions are prone to vulnerabilities like hijacks, replaying cookies, and session fixation. Extra caution must be taken regarding storing data in sessions.

Active record Objects should never be stored in sessions which might change that Object’s behavior while migration and future code change.

The best practice is to only store the ids of the records. Also, sensitive data like User access privileges and money based information should not be stored in sessions.

Ruby Rails Development Sphere & Associated Myths

Posted on by Lipsa

Ruby on Rails development is fast changing the norms of web development across the globe.

Companies around the world are fast catching up with this magical web development framework for exploring and executing its true potentials; thereby serving their clients with really cost-effective, quick and dynamic Ruby on Rails Applications.

Ruby developers and Rails developers are becoming the most sought after skilled professionals, for Software companies to hunt for.

Ruby on Rails, being an Open Source tool, coupled with fast development life cycle, requires much less resources in terms of Programmers and man-hours; which results in the service provider and client being the ultimate beneficiaries.

Silicon Valley based leading Software firm, Andolasoft Inc. is a formidable force to reckon with as far as Ruby on Rails development is concerned.

Never miss an update from us. Join 10,000+ marketers and leaders.

With a vast pool of Programmers as well as Domain Leads, this fairly young Enterprise has carved out many Social Networking Sites, Social Media Marketing web apps.

Andolasoft services include but not limited to RoR Development, RoR Application Migration, Social Media Integration, System Administration, Redesigning of Existing Apps, Performance Improvement Related Tasks and Rescue Support.

Irrespective of all its popularity, RoR also has few myths related to it.

Applications can be built hundreds of thousands times faster than other technologies: The fact is Rails doesn’t write the code automatically.

It just lets the developers work easy by managing certain functionalities; thereby allowing them to focus on other crucial modules.

It also manages the laborious part of lifting of user interactive modules. Having said that, such myths reflects a wrong opinion upon customers, whose expectations sometimes become too high for the service providers.

Even Non-programmers can build web applications: This is by far the silliest perception about Rails development. Although the simplicity of this framework and clean syntax of ruby language assist in quick development, but still experience is required as far as writing code is concerned.

Rails developers do need to write new and unique code, apart from using the Rails conventions on top a comprehensive web development framework.

The Horizons of CakePHP Application Development

Posted on by Ajay Sahoo

CakePHP is an open-source web development framework for PHP. It came into prominence around 2006 and it was inspired by the Ruby on Rails framework, which was introduced around a year prior to it.

CakePHP follows MVC pattern architecture. Like RoR, it also follows the two key design features, DRY or “Don’t Repeat Yourself” and CoC or “Convention over Configuration”.

CakePHP development is a rapid development framework with thoughtful, coherent design and is well aided by friendly community contributions. It relies on a ORM (Object-Relation Model) regarding database query interface.

Never miss an update from us. Join 10,000+ marketers and leaders.

Using CakePHP’s ORM, we can create, retrieve, update and delete related data into and from different database tables with simplicity and in a better way. There is no need to write complex SQL queries anymore.

Some of the key features of CakePHP are:

  • Flexible Licensing
  • Compatibility with PHP4 and PHP5
