stripos returns false when special characters is used

Question

I am using the stripos function to check if a string is located inside another string, ignoring any cases.

Here is the problem:

stripos(\"ø\", \"Ø\")         


        

Answer 1

As the other solutions say, try first with mb_stripos(). But if using this function doesn't help, check the encoding of your php file. Convert it to UTF-8 and save it. That did the trick for me after hours of research.
