Web Development Using PHP
Introduction:
PHP stands for Hypertext Preprocessor,previously known as Personal Home Page, is a widely used, general-purpose scripting language that was originally designed for web development, to produce dynamic web pages. It is a terrific language for the rapid development of dynamic Websites. Here a term has been used,the “Scripting Language”, is a programming language that allows control of one or more software applications.”Scripts” are distinct from the core code of the application .It can be embedded into HTML(Hyper Text Markup Language) and generally runs on a web server, It can be deployed on most web servers and on almost every operating systems or platforms free of charge.
PHP was originally created by Rasmus Lerdorf in 1995 and has been in continuous development ever since.
Features/Why Need/Usage:
PHP is a very popular web development language,which is very much common to all now a days. The features are as follows…
PHP is a general-purpose scripting language that is especially suited for web development. PHP generally runs on a web server.
It can also be used for command-line scripting and client-side GUI(Graphical User Interface) applications.
It can be used with many RDBMS(Relational Database Management System).
Free of licensing restrictions imposed by most commercial products.
Basically PHP is Open Source Software.
Everyone is free to participate.
Originally it is designed to create dynamic web pages.
PHP now focuses mainly on server-side scripting.
PHP is a loosely-typed language, which also increases its practicality. For example, there is no need to explicitly create, typecast, or destroy a variable, although you are not prevented from doing so.
Create and manipulate Macromedia Flash, image, and Portable Document Format (PDF) files
Evaluate a password for guess ability by comparing it to language dictionaries, and easily broken patterns
Communicate with the Lightweight Directory Access Protocol (LDAP)
Parse even the most complex of strings using both the POSIX and Perl-based regular expression libraries
Authenticate users against log in credentials stored in flat files, databases, and even Microsoft’s Active Directory
Communicate with a wide variety of protocols, including IMAP, POP3, NNTP, and DNS, among others
Communicate with a wide array of credit-card processing solutions.
PHP developers are rarely bound to any single implementation solution.
PHP’s powerful string-parsing capabilities is another feature indicative of the possibility offered to users.
PHP is a loosely typed language, that is, a variable has different values
depending on the context in which it is being evaluated.
open development and auditing process.
The recurring theme here is that PHP allows you to quickly capitalize on your current skill set with very little time investment.
PHP has also attracted the development of many frameworks that provide building blocks and a design structure to promote rapid application development (RAD).
PHP is commonly used as the P in this bundle alongside Linux, Apache and MySQL,which is basically known as LAMP Architecture.
Security:
PHP provide lots of security to develop a website than any other scripting languages. Those are as follows..
The NVD(National Vulnerability Database) stores all vulnerabilities found in computer software.
Most of these PHP-related vulnerabilities can be exploited remotely.
Hosting PHP applications on a server requires a careful and constant attention to deal with these security risks.
PHP Secure the web development to protect from lack of input validation.
It can also provide some function by which password cookies is being more secure.
Speed Optimization:
As with any interpreted language, PHP scripts are stored as human-readable source code and are compiled on-the-fly by the PHP engine.
In order to speed up execution time and not have to compile the PHP source code every-time the web-page is accessed, PHP scripts can also be stored in binary format using PHP compilers.
Code optimizers aim to reduce the run-time of the compiled code by reducing its size and making other changes that can reduce the execution time with the goal of improving performance.
Another approach for reducing overhead for high load PHP servers is using an Opcode cache.
PHP is way faster then any other server scripting language.
