pattern help

[Destramic]

hey guys, i'm trying to get back in to the swing of things after a lot of time out from programming, and i'm struggling with this simple regex pattern if i could get some help please.

 

i've decided to go over some of my code and try and re-write things better....starting with my framework.

 

 

here is my pattern:

/^\/?(i|s)?:+([A-Za-z0-9_-])$/

what im trying to do is match:

 

news/i:news_id   - returning strings i (if there) and news_id

 

as the string is uri it could contain a forward slash at the beginning.

if (preg_match_all('/\/?(i|s)?:+([A-Za-z0-9_-])/', 'my-page/i:foo/:bar', $fixed_parameters))
{
    print_r($fixed_parameters);  
}

result:

Array
(
    [0] => Array
        (
            [0] => i:f
            [1] => /:b
        )

    [1] => Array
        (
            [0] => i
            [1] => 
        )

    [2] => Array
        (
            [0] => f
            [1] => b
        )

)

idealy what i'd like is a result like this:

Array
(
    [0] => Array
        (
            [0] => i
            [1] => foo
        )

    [1] => Array
        (
            [0] => 
            [1] => bar
        )

)

thanks guys

You aren't repeating that character set at the end.

 

As for the format, [0] will always be the full match. Best you can get is "i" as [1] and the identifier as [2] by using what you have now with the PREG_SET_ORDER flag.

brilliant thank you very much requinix.

 

i used this pattern which seems to work fine

/(i|s)+:+([A-Za-z0-9_-]\w*)/
