In this tutorial, we’ll create a CRUD (Create, Read, Update and Delete) example application with a MySQL database. We’ll also see how we can build modern PHP applications with a frontend UI built with the latest Angular 8 framework.
PHP is a server language that can be used to build server-side web apps while Angular is a client-side platform for buiding front-end web apps and mobile apps. So, how can both technologies be connected for developing the same app?
Web apps have both a frontend and backend so you can use PHP in the backend for accessing server resources like a MySQL database and use Angular in the frontend to structure and build the user interface which usually consumes and renders data coming from the server.
Traditionally, PHP takes care of preprocessing the PHP code and rendering an HTML page then send to the client browser. With Angular, this is not the case anymore since the processing that was done in PHP is now done in the browser thanks to Angular.
There are two approaches for connecting your Angular frontend with your PHP backend:
Use separate Angular and PHP apps: In this approach, you need to build and expose a REST API from your PHP backend. PHP is now used to interact with the database and send JSON responses to the frontend which you need to build as an Angular frontend app that consumes the REST API by sending HTTP calls to the API endpoints and render the received data. This is the best approach since it allows you to build one backend that can be connected to multiple web and mobile apps.
Use one app that contains both PHP and Angular: In this case, your PHP app needs to be able to serve the Angular frontend.
PHP stands for Hypertext Preprocessor. PHP is a the most popular programming language for building web applications. It’s an open source scripting language that runs on the server. PHP is free to download and use and easy to learn
PHP 7 is the latest version of PHP which brings many new features to the language:
To complete this tutorial and build a web application you need to have some basic understanding of the following technologies:
Throughout this php tutorial we assume you have a development machine with these requirements installed:
PHP scripts use the
Before adding PHP code inside a script file that ends with
.php you need to start your code with
<?php tag and ends it with
For example, this is a file that displays a Hello World! string:
<!DOCTYPE html> <html> <body> <h1>PHP Example</h1> <?php echo "Hello World!"; ?> </body> </html>
The script contains an HTML document with php code. The server processes this script without touching the HTML code but only the PHP code between
?>. In this example, the php code use the
echo function to output the Hello World! string.
echo "Hello World!"; is a php statement. It ends with a semicolon
You can also add comments alongside with your php code using
# for single-line comments and
/* */ for multi-line comments.
PHP is a programming languages which has a sole purpose to create back-end web applications while Python is a general purpose programming language that can be used for web development and other fields such as data science and scientific calculations so our comparison will be between PHP and Python equipped with a web framework. The most popular web frameworks for Python are Django and Flask with Django being more popular than Flask.
In order to compare PHP with Django we need to consider many factors such as:
More experienced developers have more potential to quickly learn a new programming language than beginners
Both PHP and Python are popular languages. They are both extremely popular among web developers and power most of the websites on the web today.
Let’s take a look at these three factors:
Both PHP (dominates 80% of the market)and Python are popular languages, but for web development PHP is more popular than the most popular framework for web development in Python which is Django.
Popular websites like Facebook and Wikipedia are built in PHP.
Also many popular website and apps that you use daily are using Python. For example, YouTube, Reddit, Pinterest and Instagram etc.
A learning curve describes how easy or difficult the programming language is? Which simply means how easy to become familiar with the programming syntax and to start implementing requirements using the language.
Python is a lot easier than PHP since it has clear and readable syntax so for a beginner developer it would be easier to learn. Many universities in the world are using Python as the first programming language for their students.
On the other hand, PHP has a less readable and confusing syntax which makes the learning process for a beginner developer more difficult, but to be fair, once your learn and become familiar with the syntax you can start creating websites with the same ease.
PHP has many libraries, frameworks and CMSs than Python. For example WordPress, the most popular CMS platfrom which everyone is using create a website is built in PHP. Also popular eCommerce solutions like Magento and WooCommerce are developed in PHP. Python with Django also offers many libraries a quite a few CMSs but not as equal to PHP.
Now let’s see a list of pros and cons for both Python (and as a result Django) and PHP:
Let’s start with Python pros and cons:
The pros and cons of PHP:
In this tutorial, we’ve introuced PHP for Angular 8 developers. Next, we’ll see how to create a modern PHP application with REST APIs and Angular 8 interface.
