Programming: The complexity of the task determines the cost and timing of the development of the site.

The complexity of the task determines the cost and timing of the development of the site. A qualified team can even cope with a complex site in one to two weeks.


Programming is now needed everywhere. Existing programming languages ​​are developed and numerous (in chronology - Assembler, BASIC, C, C ++, C #, COBOL, Fortran, Java, JavaScript (JS), Lisp, Pascal, Perl, PHP, Python, Ruby, Smalltalk, Visual Basic .NET ( VB.NET) ...). The most extensive and important for the everyday economy sphere of programming is website programming.

How are sites created?

To create a good site you need a whole team of specialists. What the user directly sees on the screen - the placement of texts and images, sets a relatively simple html programming language. But the "permanent" pages will not satisfy anyone, they need to be given dynamics, the ability to respond vigorously to user actions. The javasacript language is responsible for this. Its capabilities are limited, you cannot write files to the user's computer (what viruses can use), enter information for storage in databases. Therefore, the server uses a more powerful php programming language. With it, you can "on the go" create web pages in html language, with short commands perform complex actions to exchange data between the client and server.

Simple sites, similar to existing ones, are made easy. It is enough to adjust the template to the particular customer. The development of a complex specialized site is a non-trivial task, it will take a lot of painstaking work of specialists. But it turns out an impressive result.

When programmers created the basis of the site, designers who prepare images, sound and video are taken for granted; and copywriters writing site-specific texts. If you need a lot of texts, you can temporarily launch a simplified version of the site, gradually replenishing it with new information. Next, the site needs an administrator who will monitor its availability and serviceability, install updates, and “ban” unwanted users.

Turnkey website order

So that specialists can quickly create a high-quality website, you need to correctly set the terms of reference. This is, if possible, a detailed description in human language of how the site should look and behave. A professional taskwriter is no less valuable employee than an experienced programmer. If the client finds it difficult to put the terms of reference in "written" form, the professional interviews the customer and, based on his answers, prepares all the necessary items. 

A programming language is a set of specifications defining its syntax and semantics. We are currently using programming languages ​​that have emerged thanks to the evolution of "third generation languages" by the improvement method. Since the 1960s, a logical programming language, functional programming (with support for processing arrays), structural programming, declarative and visual (graphical) programming languages, an object-oriented programming language have appeared ...

Today, programming languages ​​are developing in the direction of improving security and reliability, creating new forms of modular organization of code and integration with databases (Database Management System (DBMS) - Hierarchical, Network, Relational, Object-Oriented, Object-Relational.). Many modern languages ​​are specifically designed to facilitate object-oriented programming.

Object Oriented Language (OOJ): Key Elements

Declaring classes with fields (data) and methods (functions).
The mechanism of class extension (inheritance) is the creation of a new class with the inherited features of the ancestor class.
Polymorphic variables and parameters of functions (methods) that allow you to assign instances of different classes to the same variable.
Polymorphic behavior of class instances through the use of virtual methods.

Some languages ​​use additional tools. for example: Constructors, destructors, finalizers, Properties (accessors). Indexers. Controls for the visibility of class components (interfaces or access modifiers, such as public, private, protected, feature, etc.)

Our web programmers mainly use the php language (php server-side programming language) to create websites.

PHP programming (Personal Home Page) is a scripting language that is intensively used for developing web applications, is supported by the vast majority of hosting providers and is one of the leaders among the languages ​​used to create dynamic websites.

In the field of web programming, PHP is one of the most popular scripting languages ​​(along with JSP, Perl and the languages ​​used in ASP.NET), due to its simplicity, speed of execution, rich functionality, cross-platform and distribution of source codes (PHP licenses) .

PHP - rich in a set of built-in tools for developing web applications:
 - automatic extraction of POST and GET parameters, as well as web server environment variables in predefined arrays;
 - Interaction with a large number of different database management systems (MySQL, MySQLi, SQLite, PostgreSQL, Oracle (OCI8), Oracle, Microsoft SQL Server, Sybase, ODBC, mSQL, IBM DB2, Cloudscape and Apache Derby, Informix, Ovrimos SQL, Lotus Notes, DB ++, DBM, dBase, DBX, FrontBase, FilePro, Ingres II, SESAM, Firebird / InterBase, Paradox File Access, MaxDB, PDO Interface);
- Automated sending of HTTP headers;
- work with HTTP authorization;
- work with cookies and sessions;
- work with local and remote files, sockets;
- processing files uploaded to the server;
- work with XForms.

PHP Included in LAMP (Linux, Apache, MySQL, PHP) and WAMP (Windows, Apache, MySQL and PHP) - a common set of software for creating and hosting websites. The language is used by hundreds of thousands of developers. LAMP software products were not specifically designed to work with each other, but LAMP has become very popular because of its flexibility, performance and low cost (all of its components are open source and can be downloaded free of charge from the Internet).

* Linux / Windows - operating system
* Apache - web server;
* MariaDB / MySQL - DBMS;
* PHP is a programming language used to create web applications.
