glfwSetMouseButtonCallback

This function sets the mouse button callback of the specified window, which is called when a mouse button is pressed or released.

function glfwSetMouseButtonCallback(\GLFWwindow $window, callable $callback) : void

Example: 

glfwSetMouseButtonCallback($window, function($button, $action, $mods) {
    if ($button == GLFW_MOUSE_BUTTON_LEFT && $action == GLFW_PRESS) {
        echo "Left mouse button pressed" . PHP_EOL;
    }
});

When a window loses input focus, it will generate synthetic mouse button release events for all pressed mouse buttons. You can tell these events from user-generated events by the fact that the synthetic ones are generated after the focus loss event has been processed, i.e. after the window focus callback has been called.
