How to get integer value of a string type data

Time:12-06

I have a url goes like this:

https://sitename.com/nhd/my_student/nhd?olympiad=4

And by using \Request::getQueryString(), I get this string value:

olympiad=4

Now I need to get only the number 4 from this string.

How can I do that?

CodePudding user response:

use request query method

request()->query('olympiad');

or

$request->query('olympiad');

Also query($key = null, $default = null) method accept default value as second param.

To get all query params use $request->query() so you get all query params in array.
