动态更改超链接参数值

Question

Please advise on how to do this.

I have a html page with two different links like below

1)  http://domainONE.com/?a=100&b=$bvalue (this url is around in 45 places)
2)  http://domainTWO.com/?a=200&b=$bvalue (this url is around in 30 places)

Now I would like dynamically change (prefer PHP based solution) to assign b= value(like link1, link2 link3…link45) for domainONE.com and then b= number (like link46, link47 link48…link75). Looking to assign the b=$bvalue using a loop or other ways based on domain name so I don't have to hardcode by finding each url on the page with link1 till link75)

I can explain more if it's not clear. I am trying not to use jquery based solution thinking if that takes time to manipulate.

Regards

Something like this with a switch:

switch($_SERVER['SERVER_NAME']) {
    case 'www.domain1.com':
        $bvalue = 100;
        break;

    case 'www.domain2.com':
        $bvalue = 200;
        break;
}

Or something with an array:

$domains = array('www.domain1.com' => array('bvalue' => 100),
                 'www.domain2.com' => array('bvalue' => 200),
);

$current = $_SERVER['SERVER_NAME'];

$bvalue = $domains[$current]['bvalue'];

Depending on your requirements you might look through $_SERVER specifically $_SERVER['HTTP_HOST'] for something else or you may need to manipulate it somewhat to get the string that you want.
