php string finding substrings

Question

Sorry if this is a newbie question. Lets say I have this string (the values name and server can change): Also I forgot to say that I know the length of 'something' .

$str='something-name:Jon,server:localhost'

Now I must pull the values: 'Jon' and 'localhost' and put them in variables.

What I am doing now:

if ((strpos($str, 'something')) !== false){
    $par_name = strpos($str, 'name:');
    if ($par_name !== false){
        $name = substr($n, 20);
    } 
}

Now:

$name == 'Jon,server:localhost'

Instead I need to get only the name and the after the server substring.

$name == 'Jon'
$server == 'localhost'

I guess I have to find the exact value for the third parameter of substr. I dont know.

Thank you for your responses.

You can do this easily with explode(). Split the string with comma as the delimiter, split the parts with colon as the delimiter, and grab the part before the colon in both the parts:

$str='something-name:Jon,server:localhost';
list($part1, $part2) = explode(',', $str);
list(,$name) = explode(':', $part1);
list(,$server) = explode(':', $part2);

Demo!

Yes, indeed, is a way cleaner than mine, but use of list sometimes take from readability. It's not the case here, contrary, here give readability.

It's just a fast example of how you could achieve this:

$str='something-name:Jon,server:localhost'

$explode = explode(',', $str);

$explodePart1 = explode(':', $explode[0]);

$explodePart2 = explode(':', $explode[1]);

$name = explodePart1[1]
$server = explodePart2[1];
