使用URL上的爆炸来获取每个字符串的数组编号

Question

Hi I'm trying to get the controller from a url request for example:

$url = http://www.yourDomain.com/request/code

I'm using this code:
$control = array();

$control = explode('/', $url);

now i would like to get the 'request' string from that url so i use:

$get = $control[3];

I think I'm confuse about the numbering of the array since there is two slashes after http:

would array assign a number in between slashes?
something like this

$control[0] = http:
$control[1] = '';
$control[2] = www.yourDomain.com;
$control[3] = request;
$control[4] = code;

The part with double slashes confuses me.

Answer 1

In this case a null value will also can be assigned to array so your array should be like this...

Array
(
   [0] => http:
   [1] => 
   [2] => www.yourDomain.com
   [3] => request
   [4] => code
)
