What is the difference between render() and print()?

Answer 1

The render() function in Drupal is used to render render arrays using drupal_render(). print() is not nominally a function, but a PHP language construct that prints a string to the screen. In fact, a complete analogue of echo, with the only difference - it always returns 1.

Answer 2

Does PHP have a render function?
