How can I pass an id of "0" into my application URL? (CodeIgniter)

I'm using codeigniter for my projects and I would like to pass an id of 0 into the URL:

/resource/method/id

which translates into

/resource/method/0

the problem is that CodeIgniter ignores the 0 and responds to

/resource/method

Any workaround for this?

Solution

  • The reason why codeigniter, rather PHP is ignoring the id of 0 is because of PHP's type juggling.

    0, "" (empty string) and false are all the same to PHP

    When getting the URL segment, if codeigniter doesn't see the parameters it returns false. Although this is probably why you aren't getting the value. I've never seen the framework ignore the id.

    Remember that: (false == 0) is true while (false === 0) is false

    The first example checks if both values are equal, while the second checks if both are equal and the same type
