Introduction to PHP Hypertext preprocessor


Introduction to PHP.


It was originally created by by Rasmus Lerdof in the year 1994. The reference implementation is now generated by the PHP group. Initially represents the personal home page, but now it supports PHP: Hypertext preprocessor.
However, A programming language that allows developers of web page programmers to create dynamic content that interacts with the database. It is mainly used to develop web-based software applications.
This article is designed for Hypertext preprocessor. programmers. This is the new concept of code, but they have a basic understanding in computer programming.
Its a server-side scripting language embedded in html. In addition, It can also be used in conjunction with various web template systems, web content management systems, and frameworks. It is used to manage dynamic content, databases, session tracking, and even build an entire e-commerce site.


Run the  code:

The  code is usually handled by a  interpreter implemented as a module in a Web server or as a CGI (Common Gateway Interface) executable. The web server combines the results of the code interpreted and executed, which can be any type of data (including images) and generated pages.Code  also run using the command line interface (CLI) and can be used to implement stand-alone graphical applications.
The standard php interpreter driven by the Zen engine is free software released under the php license. IT has been widely ported and can be deployed on most free web servers on almost any operating system and platform.

MySQL database in php:

MySQL uses this code as a backend tool.However, MySQL is a popular online database that can be well with  interfaces. Therefore, this code and MySQL are very good choices for webmasters to look to automate their websites.PHP

Operating system in php:

Therefore, It can run on UNIX and Windows servers.
It supports a large number of major protocols, such as POP3, IMAP and LDAP. Hypertext preprocessor4 adds support for Java and distributed object architectures (com and CORBA), making n-tier development the first possibility.
Common use.
Add, delete and edit elements in the database via php.
II. access to cookie variables and setting cookies.
III. using this, you can restrict access to certain pages of your website.
IV.Finally,  the data is encrypted.


Five important features make possible the practical nature of code
I. concise
II. efficiency
III. security
IV. Additionally, flexibility

Therefore, the general php is inexpensive, secure, fast and reliable for the development of web applications.
