What is PHP?
PHP is a server-side programming language commonly used to build dynamic websites. Unlike HTML and CSS, PHP runs on the server before a page is shown to the user. It’s used to handle things like forms, databases, user logins, and content management systems like WordPress. PHP allows websites to respond to user actions instead of just showing static content. If you’ve ever logged into a site or submitted a form, PHP was likely involved behind the scenes.
How PHP is used in real life
PHP is used behind the scenes to make websites actually do things. It helps handle forms, save information to databases, manage logins, and show different content based on what a user clicks or submits. Platforms like WordPress rely heavily on PHP to load pages, posts, and themes dynamically. Anytime a website responds to you instead of just showing static text, there’s a good chance PHP is making that interaction happen quietly in the background.
