PHP is open source general-purpose scripting
language that is especially suited for web
development. It allows web developers to create
dynamic content that interacts with databases and
is basically used for developing web based
software applications. PHP is the back end just
like HTML is the front end. Without PHP,
developing interactive websites is not possible.
This is where the scope of learning, understanding

and working with PHP Training Course in
Chandigarh comes in.

In today’s online world, PHP-constructed websites
have a strong hold. Almost 77.4% of all today had
their server-side applications built using PHP. It’s
obvious that this programming language has its
fair share of lovers — though there are also a few
haters in the mix.
With the rise in popularity of languages like
Python, some programmers are now pointing out
the drawbacks of PHP when making a website.
Amongst a sea of benefits, this scripting language
is not without its faults.
In this article, we’re going to clearly define the
advantages and disadvantages of the PHP
programming language, check out its capability
and functionality, and see how it compares with
other scripting languages.

What is PHP Used For?
PHP, now known as PHP: Hypertext Preprocessor,
is an open source scripting language created by
Rasmus Lerdorf some three decades ago, and is
mainly used by developers to create web pages
and websites (such as ecommerce sites,
professional websites, marketplaces, etc.). You can
also use its syntax to create web applications and
GUIs (graphical user interfaces). The recent
versions of this scripting language, such as PHP 7
and PHP 8, are object oriented, which helps
developers create secure frameworks and
functions that are dynamic and reusable.
PHP Features
While the list of PHP pros and cons is considerable,
its number of useful features is extensive. Let’s
explore what the core PHP team has done to make

this language stand out over HTML, Python, C
language, and others.
1.Open source
One of the key PHP benefits is that it is entirely
open source, meaning that users don’t have to
shell out any money to use the frameworks, run
code; use its database, debugging tools, etc. You
can simply download the language and create
websites and web applications any time you want.
2.Extensive library
Programming language libraries have codes that
are pre-written and optimized to run tasks
smoothly and to reduce poor performance. Instead
of starting a code from scratch, you can just access
the library and borrow code to make your tasks
run at maximum efficiency and speed. You can also
explore resources like Symfony, Django,
CodeIgniter, etc.

3.Adaptable with multiple platforms and
technologies
Why do popular content management systems like
WordPress use PHP, you ask? Well, it’s because this
scripting language is highly flexible and adaptable.
Exhibit A: if you need PHP and MYSQL to work
together, it can be done. Exhibit B: you can also
run it on a plethora of operating systems such as
Windows Linux, UNIX, Mac OS, and others.
4.Community support
Another benefit of using PHP language is that,
aside from just the code, it has extensive
community support as well. For any question you
have, the chances are high it has already been
asked and answered. The community on, so you’ll
find multiple resources in the form of web-based
content, such as audios, videos, blogs, etc.

5.Other features
Another benefit of PHP web development is that
maintenance is an easy task — especially when you
have frameworks like Model View Controller (MVC)
acting as a helping hand. You also get access to
real-time insights, super-fast speed, the ability to
use the software on multiple platforms, and its
enhanced security features.
Advantages of PHP Over
Other Languages
Now that we’re done discussing the and whys, let’s
come to the topic you’re actually reading the
article for — understanding PHP advantages and
disadvantages.
1.Scalable

If you’re working on a large-scale project and need
the help of a scripting language that can get the
task done well, then this is the language for you.
Facebook, WordPress, Tumblers, Yahoo,
MailChimp, iStockPhoto and others were all
created using PHP. Since one of the main
advantages of PHP is that it loads fast, it also
means the people coming to your website won’t
experience long wait times.
2.Free to use
Scripting languages can be of two types — open
source and closed source. Open source language
refers to languages that are free; closed source
refers to the languages that are paid. PHP is one of
the most popular languages on the server side
scripting world that doesn’t require any fee. You
can use frameworks, syntax, libraries, databases,
and all of its functionalities for free.
3.Community support
One of the biggest advantages of using PHP in
web development is that the support of the PHP
community is extremely strong. If you’re stuck with
a problem somewhere in development you can
pose a question to the community and you’ll have

multiple software developers around the world to
help you. PHP Community is one of the most
active communities in the web development world.
4.Ease of use
When it comes to programming languages, PHP is
one of the easier ones to learn. This is because
Even though its syntax is rigid, it is also forgiving.
Aside from this obvious benefit, you can also
access multiple libraries and resources to ensure
that your code is optimized for speed and
efficiency.
5.Lightning speed
While we’re living things up in the “pros and cons
of PHP” columns, let’s address one of the biggest
pros of PHP — its lightning speed. According to
many experts, this programming language is
almost three times as fast as Python, and the
current versions (#7 and up) are even faster than
the previous versions. As per Benchmarks Game’s

data, a PHP web page takes approximately 17.81
seconds to load.

adopt it into your own web applications, feel free

PHP Drawbacks
We mentioned that this language is not without its
faults, so let’s explore what they are, and what the
common complaints developers have with PHP.
1.Not as versatile
If you’re planning to use this scripting language
exclusively for building websites and web
applications, then you’re all set. In that case, we’d
even recommend you contact us to hire PHP
developers. However, if your project is more
extensive and you’ll need technologies like
machine learning, artificial intelligence, big data,
etc., to make everything come alive, then you
might need to consider another programming
language.

2.Limited debugging tools
One common complaint most developers have
about PHP is that it has limited debugging tools. It
handles errors poorly, especially when compared
to other scripting languages — this is mainly
because the debugging tools that are needed to
track and search for such errors don’t work as well.
3.Can’t modify core behavior
Suppose you’re working on a task, and your
primary goal is to make it as creative as possible —
then PHP is not the tool for you. This is because
PHP as a scripting language does not allow any
modifications or changes to the behaviour of web

applications. This means you’ll have some
restraints in trying to achieve new outcomes.
4.Security is not the best
Since PHP is open source code, it also means that
it has an ASCII text file, which is easily accessible.
This basically means that whatever code you write,
the general public can easily view it, along with all
the bugs your code has. This also means that they
can use those bugs against you. Ergo, security is
not the best.
5.There are easier-to-use languages
PHP is a pretty easy-to-use programming
language. If you’re already a developer you’ll
master it in no time. However, this language is
written like code. When you compare it to Python,
which is written like English, you realize that even a
beginner can grasp Python. Hence, even though

PHP is easy to understand, there are easier
languages out there.
What kind of internet would it be if the websites
designed are just plain information and links? It is
hard to imagine this during these days when
almost all web pages are interactive and engaging.
These web pages are dynamic web pages. A
dynamic web page is a web page that displays
different content each time it is viewed while
retaining the same layout and design.
PHP is one of the back-end languages used as a
scripting language. A server-side dynamic web
page is a web page whose construction is
controlled by an application server processing
server-side scripts in the back-end.
PHP is a server-side scripting language that can
be easily embedded in HTML code. A scripting
language is a programming language for runtime
environments that not only automates the
execution of tasks but also performs several other
tasks such as creating plugins and extensions,
system administration. The applications are written
on it run on web servers and do not depend on
web browsers.

There are certain features of PHP that make it
stand out from other scripting languages. We shall
explore the features of PHP in this article, and we
shall also discuss why PHP is so popular amongst
its users.
PHP is an acronym for Hypertext Pre-processors.
It is an open-source, interpreted scripting language
created by Rasmus Lerdorf in 1994. PHP contains
HTML with embedded code that does some tasks.
A PHP code starts with <?php and ends with ?>.
An example of PHP script:
This is a PHP script!
Being a server-side scripting language (unlike
JavaScript, which is a client-side scripting
language), it is used to manage the dynamic and
interactive content of a website and is executed on
the server-side. PHP is fast and easy to learn. It
can be embedded in HTML, making it easier to
add functionalities without needing to call external
files or data as it can be easily connected with a
wide range of databases.
PHP has something to offer everybody- it is
extremely simple and friendly for beginners, and it
has lots of features for professionals. Over the
years, the role of PHP has shifted, and it has now

become one of the most popular programming
languages in the world.
Why use PHP?
PHP is a very popular language because it is
simple and is open-source. There are many
convincing reasons for why you should be using
PHP, some of them being:
 It is easy to install and learn.
 It is open-source and therefore free.
 Not only that, but it is fast and secure.
 It runs on various platforms (Windows, Linux,
Unix, etc.).
 PHP can access cookies variable and set
cookies.
 It supports many protocols, such as HTTP,
POP3, LDAP, IMAP, SNMP, NNTP, and many
more.
 It is well-connected with databases and
supports a wide range of databases. This
feature also makes it suitable for handling
forms.
 Many references and learning materials are
available for PHP are available over the
internet.

Features of PHP
We have learned about PHP and its uses. But
what are the features that make PHP popular
Now that we have a basic understanding of PHP,
let us see some of the most striking features of
PHP
Simplicity
PHP is particularly famous for its simplicity. It is
organized and easy to learn. Even beginners won’t
face any hard time learning and using PHP. It is a
very well-organized programming language, and it
comes with a lot of pre-defined functions, which
makes the task of the programmer easy. There is
no need to include libraries i
Flexibility
n PHP like C. With a lot of pre-defined functions,
PHP is easy to optimize as well.
PHP scripts can run on any device- mobile, tablet,
or PC. It is very compatible with various
databases. It can be easily embedded and

integrated into HTML, XML, and JavaScript.
Likewise, it is also compatible with almost all
servers used today like Apache, IIS, etc.
Objective oriented
PHP supports object-oriented programming
features like data encapsulation, inheritance,
abstraction, polymorphism, etc. The Object-
oriented programming feature was added in PHP5.
This feature helps in building complex reusable
web pages and makes PHP comparable to
powerful object-oriented languages like Java and
Python.
Interpreted language
PHP is an interpreted language, which means
there is no need for compilation. Interpreters run
through a program line by line and execute the
code. Since interpreters execute source code
themselves, the code becomes platform-
independent. Some other benefits of interpreted
language include dynamic typing and short
executable program size.

Efficient
PHP is a versatile, reliable, and efficient
programming language. The memory
management of PHP is very efficient. Great
session management, eliminating unnecessary
memory allocation, are some of the features that
make PHP efficient.
Fast Performance
PHP scrips are usually faster than other scripting
languages. Users can load their web pages faster,
and they love it. PHP code runs faster than most
of programming languages because it runs in its
own memory space. Not only that, but its
connection with databases is also fast and
efficient.
Free and open-source
PHP is open-source, which means it can be
downloaded and used freely. There is absolutely
no hassle to acquire a license to use it and no
payment is required to use it, so it is kind to your
pocket too!

Case-sensitive
PHP is a partially case-sensitive language.
Although functions names are not case-sensitive,
other things in PHP are case-sensitive. The
following things in PHP are case-sensitive:
 Variable names
 Constructs (if, if-else, if-elseif, while, do-while)
 Keywords (such as true and false)
 User-defined functions and class names
Security
PHP has many pre-defined functions for data
encryption. Users can also use third-party
applications for security. Security and flexibility are
often contrasting features, but PHP somehow
manages to offer them both, and that’s great. PHP
is designed specifically to be a more secure
language for writing CGI (Computer-generated
Imagery) programs. Security algorithms such as
Sha1 ( secure Hash algorithm 1) and
MD5(Message digest 5) are used to encrypt the
strings in PHP. Filter_var and strip_tags functions
help to keep the environment more secure and
safe for users.

Platform independent
We can run PHP on any device and operating
system (Microsoft Windows, macOS, Linux, RISC
OS, or UNIX). We can easily connect it with
various databases and is also compatible with
almost all web servers used today (Apache, IIS,
and others). It supports a wide range of databases
as well. Its cross-platform compatibility makes
really popular among its users as it saves a lot of
time and energy.
Loosely typed language
PHP supports variable declaration without
declaring its data type.
Real-time access monitoring
PHP provides real-time information about users’
access. It provides a summary of recent accesses
of the user. PHP offers a secure user
management system and prevents unrestricted
access.

Error reporting and handling
PHP has many pre-defined functions and reporting
constants that generate errors at runtime.PHP5
allows you to use semantics like try, throw and
catch, like Java and C#. There are 16 levels of
error in PHP5, representing the category and
severity of an error in PHP. Also, error reporting in
PHP is super easy with function error_reporting().
Memory and CPU use information
PHP has functions like memory_get_usage() and
memory_get_peak_usage(), which provide users
with the memory usage information. To get the
current memory usage, we can use the
memory_get_usage() function, and to get the peak
amount of memory used at a point, we can use the
memory_get_peak_usage() function. Therefore, by
using these functions, you can monitor your
memory usage and optimize your code by
eliminating the lines of code consuming a lot of
memory resources.

Active community support
PHP has got the backing and support of many
users and volunteers across the globe. These
volunteers contribute too many features and
versions of PHP libraries. They also contribute to
overcoming the language barrier by translating in
different languages to help new programmers.
Because of these volunteers, there are a lot of
third-party open-source libraries available in the
public domain providing basic functionalities as
well as complex operations.
Conclusion
At the end of the day, the language you are going
to choose depends on what you are trying to build
and the features you prioritize. Scripting languages
are in great demand these days in the era of the
World Wide Web to create dynamic web pages.
PHP comes with a plethora of outstanding
features. There are many more outstanding
features that have not been covered. Being an
open-source, fast, and reliable server-side
scripting language makes it a popular choice of
users, among various other scripting languages.
That it is one of the most used programming

languages and that too, along with languages like
Java, Python, C+, is a testament to its popularity.
