Question

I’ve a simple code like so:

echo strlen('Grækenland');

and it’s returning 11 instead of expected 10

The server is in denmark, locale was set to danish, but it still returns 11…

Answer 1

strlen is one of the naïve PHP core functions that understand strings as byte arrays and assume one byte == one character. Use mb_strlen with the correct encoding parameter to actually count characters according to the encoding of your string.
