During 2014 and 2015, a new PHP version was developed, which
was numbered PHP 7.

On 14 July 2004, PHP 5 was released
with updated Zend Engine 2.0. PHP 5 included new features such as improved
support for object-oriented programming, the PHP Data Objects (PDO) extension and numerous performance enhancements. Due to
lack of native Unicode support at the core language level PHP received mixed
reviews. In 2005, a project headed by Andrei Zmievski was initiated to bring
native Unicode support throughout PHP, by embedding the International Components
for Unicode (ICU) library.

Development of PHP was started in 1995 when Rasmus
Lerdorf wrote some Common Gateway Interface (CGI) programs in C and extended
them to work with web forms and to communicate with databases and named this implementation
“Personal Home Page/Forms Interpreter” or PHP/FI. PHP/FI 2 was released in
November 1997. Zeev Suraski and Andi Gutmans updated PHP 2 and PHP 3 was
released. PHP 3 was the first widely used version of PHP. PHP 4 was released in
May 2000 with a new core known as Zend Engine 1.0. Speed and reliability of PHP
4 is better than PHP 3. Many features were added in PHP 4. These features
include references, Boolean types, COM support for windows, output buffering,
many new array functions, expended object oriented programming, etc.

PHP supports a large number of major protocols such
as POP3, IMAP and LDAP. PHP4 added support for java and distributed object
architectures making n-tire development. PHP performs system functions i.e.
from files on a system it can create a file, read a file, write in a file,
delete a file. PHP can handle forms to get information in the form of a “form”.

PHP is an “HTML-embedded scripting
language” primarily used for dynamic Web applications. PHP was written in
the c programming language by Rasmus Lerdorf in 1994 for use in monitoring his
online resume and related personal information. PHP originally stood for
personal home page, but it now stands for Hypertext Preprocessor. It is an open
source technology and runs on most of operating system and with most web
servers. PHP is basically used for developing web based software applications. PHP
