PHP vs Node.js

What is PHP?

PHP stands for Hypertext Preprocessor, which is an open source scripting language. It is a server-side scripting language and a powerful tool for creating a dynamic and interactive website.

PHP is an interpreted language, so it doesn’t need compilation. It is specially designed for server-side scripting, which executes on the server. PHP can be easily embedded with HTML files.

Note: PHP is mainly used to develop server-side applications.

It has several advantages that are given below:

  • We can execute PHP code on different platform such as Windows, Linux, UNIX, Solaris, etc.
  • It is easy to use and learn.
  • PHP provides a built-in module which helps it to connect with the database easily.
  • PHP is an open source language that means it is available for free of cost.

In general, PHP is cheap, cross-platform, fast, and reliable to develop web applications.


What is Node.js?

Node.js is a JavaScript programming language which runs on the server. It helps to create dynamic and interactive web pages. Node.js file is saved with .js extension, and it only contains JavaScript code. It executes JavaScript code outside the browser.

Node.js is an open-source language which executes in different environments such as Windows, Linux, UNIX, and Mac OS, etc.

Node.js has many advantages which are listed below.

  • Node.js is fast and lightweight.
  • It is more secure than PHP.
  • Node.js allows us to write JavaScript code for both client and server-side.
  • Node.js offers scalability, i.e., it easy to scale the application vertically as well as horizontally.
  • JavaScript is now available for every browser and as well as it can run on each server due to Node.js.

Difference between PHP and Node.js

PHP and Node.js both are server-side scripting languages; thus, they have become the competitor for each other. They are bound to have some similarities and also some differences. Following are some differences based on their functionality and features.

FeaturesPHPNode.js
Runtime EnvironmentPHP is straightforward to install and use at server-side.PHP is straightforward to install and use at server-side.
Powered byPHP is powered by Zend engine.Node.js is powered by Google’s v8 JavaScript engine.
ExecutionPHP is synchronous except some APIs.It is totally asynchronous.
FrameworkPHP has many frameworks for easy backend development, such as Laravel, CakePHP, etc.Node.js also has popular frameworks like Express, Meteor, and DerbyJS, etc.
Execution SpeedPHP execution speed is slower than Node.js.Node.js is faster than PHP and lightweight too.
Web ServerPHP needs Apache web server to execute the code.Node.js doesn’t need any web server to execute. It runs in its own environment.
Compatibility with other languagesPHP can contain HTML, JavaScript, CSS, and even plain text.Node.js can contain only JavaScript.
Used byFacebook, Wikipedia, Yahoo, Flickr, and WordPress, etc., are using PHP.IBM, GoDaddy, NetFlix, LinkedIn, Paypal, and Walmart are the adopters of Ndoe.js.
ComplexityPHP is simpler to use than Node.js.Node.js is not too complex, but need more lines of code and callback functions.
Basic syntaxecho ‘Hello PHP’;Console.log(‘Hello Node.js’);
ModuleA developer needs to download and install PHP manually. It doesn’t come in bundled with module.It comes prepackaged with the NPM package management system and its registry.
PerformancePHP is fast, but slower than Node.js due to the database, third-party request, and file system.Node.js is faster due to its non-blocking mechanism.

PHP vs HTML

  • PHP provides a built-in module which helps it to connect with the database easily.
  • PHP is an open source language that means it is available for free of cost.

In general, PHP is cheap, cross-platform, fast, and reliable to develop web applications.

What is HTML?

HTML stands for Hypertext Markup Language, which is used to create web pages. It is basically used to create static web pages, but it can integrate with CSS, JavaScript, and PHP.

HTML is not a programming language, as it is a tag-based language. Angular brackets <> are used to represents HTML elements or tags.

  • HTML is very easy to learn and implement.
  • It is not a case-sensitive language.
  • We can write HTML code on any text editor like Notepad, Notepad++, Edit plus, etc.
  • HTML is platform-independent, hence, it can be executed on different platform.
  • It allows the programmer to add colors, audio, video, and images on a web page.

Difference between PHP and HTML

PHPHTML
PHP is a server-side programming language.HTML is a client-side scripting language.
PHP is used in backend development, which interacts with databases to retrieve, store, and modify the information.HTML is used in frontend development, which organizes the content of the website.
PHP is used to create a dynamic website. The output will depend on the browser.HTML is used to create a static website. The output of static website remains the same on each time.
PHP can manipulate the data.It cannot manipulate the data.
PHP code executes on web servers like Apache web server, IIS web server.HTML code executes on web browsers like Chrome, Internet Explorer, etc.
PHP is scripting language.HTML is a markup language.
PHP7.3 is the latest version of PHP.HTML5.2 is the latest version of HTML.
PHP is also easy to learn but not as simple as HTML.HTML is easy to learn. It can easily learn in a very short time.
PHP files save with .php extension.HTML files save with .html extension.

PHP v/s JavaScript

What is PHP?

PHP stands for Hypertext Preprocessor, which is an open source scripting language. It is a server-side scripting language and a powerful tool for creating a dynamic and interactive website.

PHP is an interpreted language, so it doesn?t need compilation. It is specially designed for server-side scripting, which executes on the server. PHP can be easily embedded with HTML files.

Note: PHP is mainly used to develop server-side applications.

It has several advantages that are given below:

  • PHP code can be executed on different platform such as Windows, Linux, UNIX, Solaris, etc.
  • It is easy to use and learn.
  • PHP is an open source language, which means, it is available for free of cost.

In general, PHP is cheap, cross-platform, fast, and reliable to develop web applications.

What is JavaScript?

JavaScript is a client-side scripting language. It is designed to create a network-centric application. JavaScript is a lightweight and case-sensitive language that has object-oriented capabilities.

We can design web pages using HTML, but cannot run any logic like arithmetic operations, check any conditions, or looping statements, etc., so to achieve this at client-side, JavaScript is needed.

JavaScript also has several advantages that are given below:

  • JavaScript is very fast as a JavaScript code executes immediately within the client browser.
  • JavaScript can easily embed with HTML, AJAX, and XML.
  • JavaScript supports all modern browsers and provides the same result on all.
  • It provides immediate feedback to the user if they forgot to enter some details.

Difference between PHP and JavaScript

PHP and JavaScript both are used for different purposes. As we have discussed earlier that PHP is a server-side script, whereas, JavaScript is a client-side script. Below are some differences between PHP and JavaScript has given:

PHPJavaScript
PHP is a server-side scripting language.JavaScript is a client-side scripting language.
PHP performs all the server-side functions like authentication, building custom web content, handling request, etc.JavaScript is designed to create an interactive web application without interacting with the server
PHP can combine with HTML only.JavaScript can combine with HTML, AJAX and also with XML.
PHP is used for back-end purpose only.JavaScript is used for both front-end and back-end.
PHP is easy to learn.JavaScript is complex to learn.
PHP is a multi-threadedlanguage, which means it blocks input/output to do multiple tasks concurrently.JavaScriptis single-threaded, i.e.,event-driven, which means it never blocks, and everything runs in concurrent order.
In PHP, the code will be available and viewed after it is interpreted by the server.A JavaScript code can be viewed Even after the output is interpreted.
It is synchronous by nature and waits for I/O operation to execute.JavaScript is asynchronous by nature and does not wait for I/O operation to execute.

PHP Indexed Array

PHP indexed array is an array which is represented by an index number by default. All elements of array are represented by an index number which starts from 0.

PHP indexed array can store numbers, strings or any object. PHP indexed array is also known as numeric array.

Definition

There are two ways to define indexed array:

1st way:

  1. $size=array(“Big”,”Medium”,”Short”);  

2nd way:

$size[0]="Big";  
$size[1]="Medium";  
$size[2]="Short";  

PHP Indexed Array Example

 

<?php  
$size=array("Big","Medium","Short");  
echo "Size: $size[0], $size[1] and $size[2]";  
?> 

Output:Size: Big, Medium and Short

<?php  
$size[0]="Big";  
$size[1]="Medium";  
$size[2]="Short";  
echo "Size: $size[0], $size[1] and $size[2]";  
?>  

Output:Size: Big, Medium and Short

Traversing PHP Indexed Array

We can easily traverse array in PHP using foreach loop. Let’s see a simple example to traverse all the elements of PHP array.

<?php  
$size=array("Big","Medium","Short");  
foreach( $size as $s )  
{  
  echo "Size is: $s<br />";  
}  
?>  

Output:

Size is: Big
Size is: Medium
Size is: Short

Count Length of PHP Indexed Array

PHP provides count() function which returns length of an array.

<?php  
$size=array("Big","Medium","Short");  
echo count($size);  
?>  

Output:
