Change the PHP Query String Variable Separator Using php.ini

By  on  

As you probably know, the default PHP query string variable separator is the "&" character. One annoyance with using the "&" character is that, in order to have valid XHTML syntax, you need to output your &'s as "&". If you'd like to avoid all of that mess, you can simply change the separating character to a semi-colon (;). Here's how:

The PHP

//inside the php.ini file
arg_separator.input = ";"

//example URL:  /page.php?key1=value1;key2=value2;key3=value3

There you go -- one easy step to outputting cleaner URLs. Do any of you use this method?

    For maximum performance, we all know we must put our assets on CDN (another domain).  Along with those assets are custom web fonts.  Unfortunately custom web fonts via CDN (or any cross-domain font request) don't work in Firefox or Internet Explorer (correctly so, by spec) though...

  1. Personally I set it to & which validates fine.

    and if you don’t have access to the ini file the following works:

    ini_set('arg_separator.output','&');
  2. pretty useful

  3. Didnt know this one, thx ;)

  4. And how Search engines see on this trick?

  5. @wsr: Search engine sees it as the same — you wouldn’t be penalized by this.

  6. @david: Maybe, but standart is “&” and many SE use this symbol to explode and analyze query string…

  7. I think this will break a 3rd party CMS(like wordpress).

    Think SEO

  9. If you really want to display pretty URLs it’s better to use mod_rewrite.

  10. Keep in mind that XML invalidates the & symbol when it’s located in the href tag.
    To validate your XML you have to supply & EG: href=”?i=1&x=2″
    When using this method the return value in the URI will return as “&”, and if you are using relative URLs in your application navigation, this will invalidate the DOM generated XML in most browsers and stop page load in Google Chrome (Safari).
    Result: href=”/mypage.php?i=1&x=2″

    Returns – EntityRef: expecting ‘;’

  11. To fix the above the first example href=”?i=1&x=2″ should read with &
    like so
    href=”?i=1&x=2″
