Does PHP support PHP redirection ?

Hi guys, I came from asp background .. (but i'm crazy with PHP now) In asp, it's support a page redirection.. it means it can force the page that gonna be send by a server considered from a condition. For example : If the condition is true then the server send page 'a.html' otherwise it will send page 'b.html' any comment please ? Thanks...
