Common uses of PHP
Apart from creating websites and applications, here are some other ways in which developers use PHP:
Databases: Scripting in PHP can be used to establish a connection with a database and retrieve or send information to the database.

Technical skills required to become a PHP developer
For PHP developers to enjoy a rewarding career, they may require knowledge and technical skills such as:
HTML, CSS and JavaScript
Developers can use PHP to create HTML, JavaScript and CSS codes. HTML gives a basic structure to a website whereas JavaScript and CSS can further enhance it. PHP collects and processes the information needed to develop web pages in HTML and JavaScript then sends the code to browsers that users use to access the web pages. Knowledge of HTML, CSS and JavaScript can equip you with the know-how of different coding languages working together on websites.
PHP frameworks
A PHP framework serves as a platform on which PHP developers can develop web applications. These frameworks offer libraries of code for commonly used functions. Using these libraries can save a lot of time for PHP developers as it eliminates the need to write the code manually. Possessing the knowledge of various PHP frameworks can help you get rid of redundancy leading to efficiency and accuracy of the code.
Database languages
Database languages can help a PHP developer define and manipulate a database. A database language consists of two languages. Data Definition Language (DDL) is used to build a database, and Data Manipulation Language (DML) is used to access a database. Learning database languages can help a PHP developer create, update and maintain databases.
Web servers
A web server is a collaboration of software and hardware deployed together to run a website. A web server's main objective is to store, process and deliver web pages when requested by the user using a web browser. The browser makes a request to a web server to communicate with PHP scripts. This communication takes place using the Hypertext Transfer Protocol (HTTP). Knowledge of web servers can give PHP developers a strong server-side PHP experience.
Content management systems
A content management system, commonly known as CMS, is an application to manage the content of a website. It enables individuals and teams to create, publish and modify content on the website. Developers have created some of the best content management systems based on PHP. Knowledge of CMS can help a PHP developer create responsive plug-ins for the CMS and gain knowledge of backend publishing programmes.
Graphic design software
Graphic design tools allow you to create appealing design elements and illustrations. A PHP developer can use graphics on websites or applications for devices to make them visually attractive. They can use graphic designing skills to integrate design elements with the PHP scripts and single-handedly create all the components of a website or an application. Knowledge and experience with graphic design can help PHP developers earn higher salaries and undertaken end-to-end freelance projects.
