So, let’s get started!

PHP – Overview

PHP is a scripting language that is open source and extensively used.

It is especially well-suited for building websites and may be incorporated into HTML.

PHP pages contain HTML with embedded codes instead of many instructions to output HTML.

PHP is different from JavaScript, which generates HTML and then transmits it while the client is unaware of the code running in the background.

How to learn PHP Learning PHP depends on how much effort you devote

PHP is user-friendly for those new to programming and provides many robust features for experienced Programmers.

Do not be intimidated by the extensive array of functionality that PHP provides.

You can hop in and start building simple apps in a short amount of time.

Even though server-side scripting is the primary emphasis of PHP’s development, the language has an array of applications.

PHP Frameworks

Developing PHP applications requires a platform known as a PHP framework.

PHP frameworks make available code libraries that contain functions that are often used, hence reducing the amount of unique code that the Developer must write.

When compared to writing PHP code from the ground up, utilizing PHP frameworks offers several advantages that are well worth considering.

Here are the following advantages:

Less Coding

When you use functions already built into the framework, you eliminate the need to develop new code as you would otherwise have to.

Common-use Libraries

A significant number of the responsibilities needed by Developers are repetitive.

Examples include sanitizing data, validating forms, and performing CRUD operations.

You can avoid the hassle of coding these functions by using the pre-written functions that come packaged with the framework instead.

Good Coding Practice

In most cases, coding standards and guidelines are adhered to by PHP frameworks.

For instance, they organize the code in an orderly fashion by function by separating it into separate folders.

They compel you to organize your code in a clearer, neater, and easier way, to maintain than it would be without.

Additionally, frameworks have naming standards for entities to which you are expected to adhere.

More Secured App Development

Utilizing a PHP framework reduces the likelihood of being exploited by a hacker; nonetheless, this does not replace the need to write safe code.

Sanitization of data and protection from the kind of common attacks described earlier are both standard features of solid frameworks.

Easy Code Maintenance

 Refactoring existing code and adhering to the DRY (Don’t Repeat Yourself) development methodology are both encouraged by PHP frameworks.

The resulting codebase with fewer unnecessary components requires less upkeep.

Because the Developers will take care of updating and repairing the fundamental structure on your behalf, you won’t even need to bother about it.

Some common PHP frameworks are:

Laravel

You can use this framework to construct web apps on several platforms.

It allows Developers to use a vast library of functionality that has already been pre-programmed (such as authentication, routing, and HTML templating).

How to learn C# take a course on the basics of object-oriented programming with C#

Access to this toolkit makes it much easier to construct sophisticated web apps in a short time while simultaneously reducing the amount of necessary coding.

Symfony

Symfony is a PHP framework with an MVC architecture and is available as a free source.

Among the community of open-source Software Developers, it is among the application frameworks with the highest level of demand.

It is utilized in the process of developing high-performance as well as complex online applications.

CodeIgniter

CodeIgniter is a PHP MVC framework that is utilized for the rapid development of web applications.

CodeIgniter comes with pre-installed libraries that allow users to connect to a database and carry out various activities.

These operations include sending emails, uploading files, and managing sessions.

Zend Framework

It has since been rebranded as the Laminas Project and is a free, OOP web application framework written in PHP 7 and distributed under the terms of the New BSD License.

The framework is a collection of expertly crafted PHP-based packages in its most basic form.

In addition, the framework uses several packages utilizing Composer as a component of its package dependency management.

Some of these packages include PHPUnit, used for testing all packages, and Travis CI, used for continuous Integration Services.

Essential PHP Topics

Most new PHP Developers are confused about learning, where to begin, and how to complete practical projects.

You can make a dynamic website or gain an understanding of how to develop a website by learning these subjects step by step, which will allow you to build a dynamic website and understand how to develop a website, as well as how PHP works and which topics are used for certain purposes.

The following are the essential topics beginners will learn in a standard tutorial:

1. Fundamentals of Programming

To begin, the Developer needs to acquire a fundamental understanding of programming to comprehend what PHP is and how it operates.

The following are some fundamentals of programming that should be familiar to every Web Developer:

  • Variables
  • Data Types
  • Operators
  • Condition
  • Loop
  • Array
  • Function

2. PHP Functions

 The Programmer needs to become familiar with the PHP built-in functions to cut down on repetitive codings, such as that for the header, the footer, the sidebar, or anything else that appears on several pages.

These functions include the following:

  • include()
  • include_once()
  • require()
  • require_once()

3. File Upload function

The Developer needs to become familiar with the PHP mechanism known as file upload.

The ability to upload files is most commonly found on websites; for instance, in the application form for college, users can submit documents, and in the application form for jobs, users can upload resumes.

The file upload functionality comprises the capability to upload a single file, the capability to upload many files at once, and the capability to upload files with validation to prevent spammers from using the feature.

4. H3 CRUD operation

The CRUD operations of the database are essential knowledge for Developers.

If the Developer is familiar with the concept of CRUD, then it serves as the central tenet of the database.

Creating (or inserting) a new record in the database is part of the CRUD operation.

The CRUD operations of the database are essential knowledge for Developers

Reading a record from the database, updating a record in the database, and deleting a record from the database are the other parts of the CRUD action.

After that, a Developer will have an easier time learning additional database issues and creating a dynamic website.

5. PHP Mail

Learning how to send mail in PHP is an important skill for any Programmer.

There are several distinct categories of e-mail, including plain text email (such as an inquiry sent via a contact form), mail with attachments (where you can upload a resume or other documents), and HTML email (Template-based mail like order confirmation email, cancellation email).

6. Sessions and Cookies

Sessions are frequently utilized in login forms to facilitate sharing of user information across several pages.

A session is used to exchange data across multiple pages.

In a login form, we show the user’s id or user name on the dashboard after successful login.

Similarly, in the registration form with numerous pages, there is a need to share certain data on the second page, third page, etc.

Cookies are frequently utilized in the process of user identification.

A cookie is a text a server saves on the user’s computer after embedding it there.

When a browser on the same machine requests a page, the cookie will be transmitted along with the request.

You can generate cookie values with PHP and retrieve previously generated ones.

7. Ajax and JSON

With the help of Ajax, you may send data to or get data from a database without reloading the page.

When we need to import or export data from other websites, we turn to JSON for support.
