PHP is a server-side programming language commonly used to power WordPress and many web applications.
Example of PHP
A WordPress template retrieves a page’s custom fields and generates the HTML sent to the visitor. PHP performs that work on the server; the browser receives the resulting markup rather than the PHP source.
Why PHP matters
It matters because development decisions affect speed, security, scalability, tracking, SEO, and maintenance. A site that looks good but is fragile or hard to update can quietly hold back every marketing channel.
