PHP’s pros and cons
Everything always has pros and cons, and programming languages, especially PHP, is no exception.
- The most important pro is open-source and free, which can download anytime and be ready for website development.
- It's an independent platform. Apps based on PHP can run on every operating system like UNIX, Linus and Windows, etc.
- Apps based on PHP can easily download and connect with databases. It’s essentially used because the load speed is faster than slow Internet, and in some circumstances, PHP speed is higher than other languages.
- PHP is understandable for beginners and easy to use, and simple. If a programmer knows basically C programming, they can easily work with PHP.

- Using PHP Frameworks’ functions can cause poor performance.
Nine main PHP’s components
Now we will continue with PHP’s main components
PHP mainly operates on the architecture module for code management and Model, View, and Controller files separation.
It can easily connect with the database and make changes without affecting other files or modules.
PHP has many different Frameworks such as Aura, Yii, Symfony, Laravel and Zend. Frameworks make source code neat and clean, manageable and help programmers work easily.
PHP mainly works on webserver software and is used by Apache server.
PHP can be used with any database, but it’s mainly used with MySQL.
Parser analyzes PHP syntaxes to HTML and sends them to the website to show content.
In this article, components are already to implement search form with PHP auto-suggest feature and MySQL database.
In PHP, Filters are used to identify data. Filters examine the valid input that is sent to avoid security problems and unexpected errors.
In PHP, system functions are performed to open files. It also helps create, read and write files.
In PHP, forms are processed, and data can be retrieved from files, saved data, emailed, and data returned to the user.
PHP can encrypt data, access and set cookies. With the help of PHP, programmers can limit users from accessing websites.
PHP is a scripting language and used widely for web app development.
PHP is extremely suitable for beginners who want to develop small apps without money to use paid tools.
Moreover, due to its simplicity, PHP is easy to learn and work with. Consider picking PHP first if you don't want to spend a lot of time learning.
