What is PHP Used For?

PHP is known as a server-side web scripting language. This means that it is primarily used for writing scripts on web servers to do things such as manage user data, handle product transactions, and keep the website functioning. It also has uses within content management systems such as WordPress and in mail lists.

Here are some common uses of PHP Programming Language:

Web Server Scripting

While you will use many languages such as HTML, CSS, and JavaScript to create the website that your customers will see, PHP is the most popular language for coding on the servers. If you need your web servers to handle things such as user data, e-commerce transactions, and server calculations then you could need PHP. Websites as large as Facebook use PHP for this purpose.

Content Management Systems

Content management systems (CMS) such as WordPress are built on top of PHP. The simple, default templates given by WordPress do not require PHP knowledge, however, if you want to create a unique website through WordPress then you will need a PHP developer.

Mailing Lists

PHP is a popular language used for creating and managing mailing lists. PHP scripts can be used to maintain lists, stylize and populate email templates, and send out emails to your customers. This can be particularly useful when you have regular newsletters being sent out.
