Parse string how-to question

[duckduckgoose]

If I have a URL that looks like this:

http://www.abcdefghijklm.com/product-cat/some-kind-of-product/ID-515-M-MAR.htm

And I want to return just the 515 value, how can I do that? I tried a combination of parse_url and substr, but my problem is that the numeric value (as well as the path) can vary in size and value.

Thanks.

Use [man]parse_url/man and [man]basename/man.

$url = 'http://www.example.com/product-cat/some-kind-of-product/ID-515-M-MAR.htm';
$url_parts = parse_url($url);
$filename = basename($url['path']);

Now it depends on the format of the filename. If the value you want is the second when the name is split by the dashes, you can use:

$filename_parts = explode('-', $filename);
// now $filename_parts[1] can be used

Use [man]preg_match/man on the $_SERVER['SCRIPT_NAME'] variable, and use a pattern like this:

$pattern = '/ID-([0-9]+)-/i';

EDIT: Posted before I saw above response. Guess you have two ways of looking at it now! :p
