PHP vs Javascript multiple url redirect script preferences and why

I have two scripts for multiple random url redirection that I am looking at to use for affiliate link replacement for all of my keyword backlinks. One of them is written in javascript and the other in PHP. I am not trying to start a flame war, so give technical reasons for your responses. Which one would seem preferable, and why.

 

I would use the PHP since Javascripts can be disabled. However it´s a downside to PHP redirect aswell, it can´t be used if the headers was already sent.

When i redirect someone on my sites i use a combination of redirects:

function RedirectTo($website) {
        //Check if php redirect is possible
	if(!headers_sent())
		header('refresh: 0;url='.$website);
		else 
                       // Post html code for both javascript redirect and meta redirect
			echo '<script type="text/javascript">window.location='.$website.'</script><noscript><meta http-equiv="refresh" content="0;url='.$website.'"></noscript>';		
}

PHP:

something like that..

 

use a metarefresh. thats works best.
