I have this link, and i need to work only with the numbers from that link. How would i extract them?
I didn't find any answer that would work with codepcetion.
https://www.my-website.com/de/booking/extras#tab-nav-extras-1426
I tired something like this.
$I->grabFromCurrentUrl('\d+');
But i won't work.
Any ideas ?
You can use parse_url() to parse entire URL and then extract the part which is most interested for you. After that you can use regex to extract only numbers from the string.
$url = "https://www.my-website.com/de/booking/extras#tab-nav-extras-1426";
$parsedUrl = parse_url($url);
$fragment = $parsedUrl['fragment']; // Contains: tab-nav-extras-1426
$id = preg_replace('/[^0-9]/', '', $fragment);
var_dump($id); // Output: string(4) "1426"
Staying within the framework:
The manual clearly says that:
grabFromCurrentUrl
Executes the given regular expression against the current URI and returns the first capturing group . If no parameters are provided, the full URI is returned.
Since you didn't used any capturing groups (...)
, nothing is returned.
Try this:
$I->grabFromCurrentUrl('~(\d+)$~');
The $
at the end is optional, it just states that the string should end with the pattern.
Also note that the opening and closing pattern delimiters you would normally use ( /
) are replaced by tilde ( ~
) characters for convenience, since the input string has a great chance to contain multiple forward slashes. Custom pattern delimiters are completely standard in regexp, as @Naktibalda pointed it out in this answer .
A variant using preg_match()
after parse_url()
:
$url = "https://www.my-website.com/de/booking/extras#tab-nav-extras-1426";
preg_match('/\d+$/', parse_url($url)['fragment'], $id);
var_dump($id[0]);
// Outputs: string(4) "1426"
