i have question simple system, can make button limit of 1 click per hour in php / sql or other? no limit per ip. reservation system in real time, can me? script of button 1 click limit per hour all.

you can store number of clicks in mysql column , increment every time user clicks button , check if click falls in past 1 hour interval , if so, tell them have wait.

something this:

select count(*) clicks_in_the_past_hour table  click_time >= now() - interval 1 hour
