The purpose of a loop in PHP is to repeatedly execute a block of code. A loop allows you to automate repetitive tasks by executing the same set of instructions multiple times. With loops, you can iterate over arrays, traverse database records, process user input, and perform many other tasks that require repetitive operations. Loops provide a way to make your code more efficient, concise, and maintainable by reducing duplication. They allow you to control the flow of execution and perform actions based on specific conditions or for a known number of iterations.
