如何在不使用'&'的情况下将2个PHP变量放在URL上

Let me explain with an example:

I have this link (php file): http:// mywebsite.com/abc/?id=fasfsa&id2=derp

On the Php I have the 2 variables id and id2.

So I'm using another php file to post the link but he has other variables and it doesn't consider mine.

Let me show how:

http: //website.com/publish.php?url=http: //mywebsite.com/abc/?id=fasfsa&id2=derp&linkname=blabla&image=http: //google.com/g.jpg

This is the sintax of publish.php. I can't edit that file. when I publish my link it shows only http:// mywebsite.com/abc/?id=fasfsa

It doesn't show the variable 'id2'. Anyone knows a method?

It doesnt show the variable id2 because it takes only his variables (url,linkname,image). I want to put all the link on the variable url .
