A statement in PHP is a single line of code that performs a specific action or task. It can include variables, functions, operators, and control structures, and is executed sequentially by the PHP interpreter. Statements are foundational elements in PHP programming, allowing developers to manipulate data, control program flow, and produce output. Every statement in PHP typically ends with a semicolon, marking the end of that line of code.
