Programming Languages Concepts: PHP Language Development Report

This report provides a comprehensive overview of the PHP scripting language, a prominent server-side technology for web applications. It begins with an executive summary and table of contents, followed by an introduction to PHP's role in web development. The report details the language's evolution, including its origins with Rasmus Lerdorf, the time periods of development, and its domain and category. It explains PHP's motivation and intended use, along with its implementation methods, which blends compilation and interpretation. The report then explores key PHP features and constructs, illustrated with source code examples, and discusses the language's coding style. A significant portion of the report is dedicated to language evaluation, including its support for OOP characteristics and MVC architecture. Finally, the report concludes with an assessment of PHP's strengths and weaknesses and includes a list of references.

Introduction
PHP is a scripting language that is used at the server side for the web applications.
This language is purely interpreter based language and therefore it does not require any
compilation process. Whenever a PHP file is run through an interpreter, it produces
corresponding HTML code.
Language Development
Designer / Developer:
PHP, as known today, is the successor to a product called PHP/FI. It was created by
Rasmus Lerdorf, in 1994. Initial incarnation of PHP comprised of a set of CGI or “Common
Gateway Interface” binaries.
Year/Time period of development:
In September 1995, Rasmus expanded the language and dropped the name. The code
went through another makeover in April 1996 and assimilating the names of prior releases,
PHP\FI was introduced by Rasmus.
Domain and Category:
Motivation and Intended use
For a long period of time the language was not regarded as a serious language to be
applicable on large Web application development.
Language overview
Implementation method:
PHP has been using blends of compilation and interpretation for providing the best
mix of flexibility and performance to the programmers. PHP has been compiling scripts down
to various instructions as it gets accessed.
Features and constructs that characterize the language:
Features of PHP:

4PROGRAMMING LANGUAGES CONCEPTS
Constructs:
The language constructs in PHP has been relatively quicker than different built-in
functions.
.
Source code examples demonstrating such features and the general
programming:
For this a program a simple program is considered. A file is created named
random.php stating the following.
<html>
<head><title>Random number</title></head>
<body>
<p>I have chosen <?php
echo rand(1, 100);
?>.</p>
</body>
</html>
Style of the language:
Some of the coding style guides followed by PHP is as follows.
 This code should utilize 4 spaces regarding indenting not tabs.
Language Evaluation
Consistent support to the different OOP characteristics
The PHP language is one of the most extensively used server side scripting language.
numerous websites are developed with this language as it provides easier operating process
and great response against the user request on the Web (Nanz & Furia, 2015).

.
Support to the MVC architecture for applications
In case of developing web applications, developers and Designers consolidate HTML
code with server side programming/scripting languages to develop dynamic website and
applications and this prompts exceptionally trapped and unmaintainable code.
.
Model: In MVC, the Model layer is mainly responsible for handling the business
rationale of at the back end of an application.
View: The View component is capable with graphical UI administration. This implies
all structures, realistic components and all other HTML components that are inside the
application (Nanz & Furia, 2015).

5PROGRAMMING LANGUAGES CONCEPTS
Controller: The Controller is mainly responsible for event handling of the deployed
application. These events at the front end can be activated by either a user communicating
with the application or by a framework procedure.
Language Assessment
 PHP integrates the HTML codes of an application easily; this causes web
servers to process the website pages before they are really shown on the web
program. Other scripting has this component yet not easily, since it is not
undeniable web improvement programming language.
Conclusion
With the different characteristics explained in the different sections of this there are
some issues that are considered as pitfalls of this language. PHP has no exceptional
concentrate on functional programming, despite the fact that it is conceivable to store a
method or function name as string in a variable and afterward utilize it to call a referenced
work.
