Simple strtolower not working
Im sure this is something obvious i'm missing but I have a string 'GB' that is stored as $str and is then echoed out using strtolower...
$str = bp_member_profile_data('field=Country');
echo strtolower($str);
I am expecting to see 'gb' (lowercase) but the output is still 'GB' (uppercase)
What could I be doing wrong?
UPDATE Turns out That the issue lied with bp_member_profile_data, this is a BuddyPress PHP function that automatically echos so it was ignoring the strtolower - Thanks to everybody for helping to narrow it down!
Answer
Try to use:
mb_strtolower($str);
This may work.
From PHP Manual:
If the input string is in different language that server locale, then you should use mb_strtolower() function.
The function prototype is:
string mb_strtolower ( string $str [, string $encoding = mb_internal_encoding() ] )
You could try adding the appropriate encoding.
The encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.
