PHP training in Chandigarh

PHP is a server-side scripting language used to create web applications and dynamic websites,

 but procedural PHP is no longer useful for making more professional and large web applications 

easier to manage. Therefore, OOP (object-oriented programming) is now the main part of PHP, 

and this course is about learning OOP in PHP.

PHP OOP explained the basics

the basic concepts of OOP in PHP, it includes all classes, methods, functions, magic work and

 techniques that are often used while creating web applications using PHP OOP.

Projects using PHP OOP

the first project will be about creating registration forms, and the final and major project will be a

 complete content management system (CMS) with an administrator.Learn PHP with

Content of this course is mostly video lectures, but with video lectures, you will also find source

 files which will be linked to each lecture, so that you can practice them and prepare projects.

Who is the target audience?

Those who want to understand basic with the practical approach of PHP OOP, they should be

 included in this course.People who want to learn PHP Object-oriented programming from very 

basic, should be included in this course

PHP Inheritance

Inheritance is one of the popular object-oriented programming features. It allows to keep shared 

properties and tasks between related classes. This feature allows us to connect with classes,

 intangible data and methods and increase re usability.

In migrating from PHP version 4 to PHP version 5, one of the noticeable changes is to present an 

object-oriented programming feature as we have seen about the development of PHP. In a limited 

set of OOPs features supported by PHP, the heritage is an attractive concept by providing the above 

listed functionality.PHP course in Chandigarh is the best place to learn PHP .

Before PHP is inherited, let us refresh the general idea about heritage and its types. According 

to this principle, one class can be taken from another class, whereas derivative orbits are called 

children or subclasses and the second is called parent or superclass. Superclass has its own

 properties and functions that can be taken from the sub-class and added to it, there may be

 properties in the sub-class.

Now the advantages of inheritance are that there is no need to redefine the essential qualities

 of the superclass again in the sub-class as they can be inherited. That is, we have said that 

legacy re usability increases and reducing the line of code, and in this way it increases simplicity

 between  the interrelated classes.

Learn PHP Programming Language Concept

Learn PHP Programming Language Concept: Definition

Full form of PHP: PHP is known as  "PHP Hypertext Preprocessor". You have not got 
any confusion because of PHP's full form, because PHP is coming in this full form. This 
kind of full to is called recursive acronym, which means an acronym which refers itself to
 itself.

PHP Programming Language: PHP is a very open source general-purpose scripting 
language that is the best option for web development. This is an HTML-embedded 
scripting language that you can embed with HTML to create dynamic web pages.
 Programmer does not just need to write heavy code of HTML, but now programmer
 coding mai can use PHP with embed tags and can also easily switch between HTML 
and PHP. PHP syntax is taken from different programming languages ​​such as C, Java,
 Perl. PHP is a very easy programming language learn PHP with
  PHP Training in Chandigarh .

PHP Features -

• PHP is also called server-side scripting language because PHP scripts execute 

on the server, and because it executes on the server, the client can not see the PHP code 
and the result is displayed on your browser.

• The power of PHP is in its compatibility, which supports different types of databases, 

as well as communicate with PHP network, IMAP, SNMP, NNTP, POP3, or HTTP.

• PHP can be run on different platforms such as Windows, Linux, Unix, Mac OS X, etc.
• PHP is almost compatible with almost all servers coming into use today, such as 

Apache, IIS, etc.

• PHP is free and you can download it from PHP's official PHP website - www.php.net
• PHP is easy to learn . Learn PHP with PHP training in Chandigarh.
• In Web Development, HTML is used by enclosing PHP script in special PHP tags.

Other Important Point about PHP -

• PHP files are extension .php.
• PHP files can be CSS, HTML, text, JavaScript and PHP code save.
• In PHP, you can not only see the output of HTML but also images, PDF files

 and Flash movies, any text, such as XHTML and XML etc. The output also shows.

PHP's ancient history

PHP was started in 1995 by Rasmus Lerdorf. They wrote 'Common gateway interface' 
(CGI) Programs 'C'. He used it to create his personal home page. Then they used it in
 a web form and used their database. Its name is 'Personal Homepage / Form Interpreter
 or PHP / IF.It is used in the creation of simple but dynamic Web application. With the 
intention to improve study and code on bug reporting, they named the application as '
Personal Homepage Tools version 1.0'. The basic functionalities of the application 
were fixed. These functions were prevalent till 2013 These were variables like Perl,
 form handling, the ability to embed HTML. Due to these characteristics, it has been in 
vogue for so long. Syntax of PHP was largely matched by Perry. But there was a lot of 
difference between them. But it was much simpler. The working area of ​​PHP was also
 very low. And it was also less consistent.PHP Training in Chandigarh is the best
 Place to learn PHP Training for creation of your own websites.

Lerdorf did not intend to make any programming language. He just kept writing the code 
of the next logical step with the intention of organizing his personal work and consequently 
a development team went up. After months of hard work and persistence with the 
development and testing teams, PHP / FI 2 was released in November 1997. This 
happened only after the beta testing. No layout or plan was created before PHP Design. 
Because it was only for personal work, Rasmus Lerdorf did not understand it. Because of 
this, the names of its functions are quite inconsistent. Its parameters are not even in the
 correct order. There was a long delay in looking for the right direction.

What is Sessions- PHP Training

What is Sessions?

Sessions are a clean way to store data for originals users against a unique session ID. This 
can be used to continue state data between page requests. Session IDs are simply sent to the 
browser via session cookies and the ID is used to fetch actual session data. The absence of an
 ID or session cookie lets PHP know to build a new session, and achieve a new session ID.

Sessions follow a simple system. When a session is started, PHP will either retrieve an existing 
session using the ID passed or if no session is catch it will create a new session. PHP will 
colonize  the $_SESSION superglobal with any discussions data after the session has started. 
When PHP shuts down, it will naturally take the contents of the $_SESSION superglobal, 
serialize it, and send it for storage accepting the session save handler. Learn PHP using 
sessions with PHP Training in Chandigarh. 

  
The advantages of using session state are:

• It is easy to applicable and is just similar to using View State.

• Appliance of data is very fast as it stock session data in memory object of the modern 
application domain.

• It ensures platform scalability and it works in the multi-process composition.

• Also it ensures data endurance, since the session state retains data even if ASP.NET work 
process restarts .

The disadvantages of using session state are:

• As the session state data is gathered in server memory, it is not desirable to use session 
state when you are working with large sum of data.

• With the use of Session state, it will distribute the performance of memory, because session 
state variable stays in memory until you destroy the state.

• If the worker Process and application domain convert all session data will be lost.

• We can't use it in web Garden outline and is not suitable for web farm scenarios also. 

PHP Training in Chandigarh used to design website design and website development.

Namespaces overview- PHP Training

What are namespaces in PHP?

In the extensive definition namespaces are a way of enclose items. This can be seen as an 
abstract access in many places. For example, in any operating system agenda serve to group 
similar files, and act as a namespace for the case within them. As a concrete example, the file  
foo.txt can continue in both directory /home/greg and in /home/other, but two copies of foo.txt 
cannot co-exist in the duplicate directory. In extensions, to access the foo.txt file foreign of the
 /home/greg directory, we must assume the directory name to the filename adoption the directory 
separator to get /home/greg/foo.txt. This same principle develop to namespaces in the programming 
world. Learn More about namespace form PHP Training in Chandigarh.

In the PHP world, namespaces are arrange  to solve two problems that authors of libraries and 
applications encounter when creating recyclable code aspect such as classes or functions:

1. Name culmination between code you fabricate, and household PHP 
   classes/capacities/constants or outsider classes/capacities/constants.
2. Capacity to other wise(or abbreviate) Extra_Long_Names intended to alleviate the
    primary issue, enhancing believability of source code.

Why Do We Need Namespaces in PHP?

As the size of your PHP code study increases, the more likely you will unwitting discuss a
 function or class name that has been announced before. The problem is distributed if you 
attempt to add third-party ingredient or plugins; what if two or more code sets device a 
‘Database’ class. The only solution has been long class/function names. For example,
 WordPress prefixes every name with ‘WP_’. The Zend Framework uses a deeply 
descriptive naming meeting that results in long-puffing class names .

How are Namespaces Defined?

By default, all consistent, class and function names are arranged in a global space — like 
they were before namespaces were backed.

Namespaced code is decide using a single namespace keyword at the top of your PHP file.

Sub-namespaces

PHP allows you to define a ranking of namespace names so libraries can be subdivided. 
Sub-namespaces are detached using a backslash (\) character, e.g.

• MyProject\SubName
• MyProject\Database\MySQL
• CompanyName\MyProject\Common\Widget
