how to get the exact length of a string in php?

I have strange result with:

strlen("òàùè")

How can I count correctly string with no-ascii characters?

I also looked at mb_strlen() but does not solve the problem.

Thanks

mb_strlen will

Return the number of characters in string $str having character encoding $encoding. A multi-byte character is counted as 1.

Your internal encoding is likely not set to utf-8, so do

echo mb_strlen('òàùè', 'utf8');

or set utf8 globally:

mb_internal_encoding('utf8');

and then do

echo mb_strlen("òàùè");

will give 4 (demo)
