I have many links with parameter number - value is numbers between 1-1000

http://mysite.com?one=2&two=4&number=2
http://mysite.com?one=2&two=4&four=4&number=124
http://mysite.com?one=2&three=4&number=9
http://mysite.com?two=4&number=242
http://mysite.com?one=2&two=4&number=52

How can i remove from this parameter and value with PHP? I would like receive:

http://mysite.com?one=2&two=4
http://mysite.com?one=2&two=4&four=4
http://mysite.com?one=2&three=4
http://mysite.com?two=4
http://mysite.com?one=2&two=4
