What role does the "echo" statement play in PHP when outputting content generated by functions?

When outputting content generated by functions in PHP, the "echo" statement is used to display the result on the screen. This statement is essential for printing the output of functions to the browser or console. It allows us to directly output the content without the need to store it in a variable first.
