Subcookies, the PHP version

As a follow-up to my last article, Take your cookies to the next level with Subcookies, I wrote a PHP equivalent.

You can download the PHP file here as a Zip archive. The file contains two classes: CookieJar and SubCookieJar. Both work in the same way as their Javascript counterparts from the previous article. There are a few things to notice though:

• All methods are static. This means you can use them like this:

  CookieJar::bake('admin','Harmen',2);
  
  CookieJar::crumble('admin');
  

• The subcookieObj parameter in SubCookieJar::bake is an associative array, looking something like this:

  $subcookies = array (
  'name'=>'Harmen',
  'age'=>22,
  'homepage'=>'whatstyle.net'
  );
  

Also, note this little oddity:

if (CookieJar::fetch('admin'))
	CookieJar::crumble('admin');

SubCookieJar::bake('admin',array('name'=>'Harmen','age'=>22,'homepage'=>'whatstyle.net'),2);
$a = SubCookieJar::fetch('admin','name');
$b = SubCookieJar::fetch('admin','homepage');
$c = SubCookieJar::fetch('admin','age').'';

SubCookieJar::crumble('admin','age',2);
$d = CookieJar::fetch('admin');

print $a;
print '<br></br>';
print $b;
print '<br></br>';
print $c;
print '<br></br>';
print $d;

The variable $c will not contain a value! I’m not sure why, ‘cause I fetched the value before crumbling the subcookie, but it’s not there. If anyone knows why this happens, please let me know.
