PHP: print '<meta http-equiv="refresh" content="0;url=' with URL parameters

Question

How do I create this string with URL parameters? What I want is something like:

print '<meta http-equiv="refresh" content="0;url=http://domain.com?a=1&b=2">';

But that doesn't pass my second parameter correctly. I get a ")" instead of a b. What am I doing wrong?

I've tried & instead of the ampersand, but that doesn't work either,

Answer 1

echo "<meta http-equiv='refresh' content='0;url=http://domain.com?a=1&b=2'>";

or even

header ("Location: url=http://domain.com?a=1&b=2");

since you are using 0 as delay

Answer 2

If you're already using 0 delay for the <meta> refresh, why don't you just use a HTTP Location redirect?

<?php
   header('Location: http://domain.com?a=1&b=1');

and if it's in the middle of a page you have to rewrite your program to make it SENSIBLE
