Tutorial example produced unexpected results

[plough]

https://www.w3schools.com/php/phptryit.asp?filename=tryphp_filter_adv3 is a tutorial example.  It attempts to validate what appears to be a valid URL but claims it is not.

I see this forum gets little use, so has the language changed since the example was created, is there a mistake in the example, or is the problem on my end in the browser?

I am using the latest FireFox browser under Windows 10.

There's nothing odd with this one. You're missing the fact that the program checks for two things

• Valid URL (FILTER_VALIDATE_URL)
• Has a query string (FILTER_FLAG_QUERY_REQUIRED)

"https://www.w3schools.com" is a valid URL, but lacks a query string and therefore does not succeed the check.
