i have some text in foreign language in my page,
but when i make it lowercase, it starts to look like this…
$a = "Երկիր Ավելացնել";
echo $b = strtolower($a);
//returns ����� ���������
i’ve set <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
could you tell me why?
thanks in advance
have your tried using mb_strtolower()?
Answer：
PHP5 is not UTF-8 compatible, so you still need to resort to the mb extension. I suggest you set the internal encoding of mb to utf-8 and then you can freely use its functions without specifying the charset all the time:
mb_internal_encoding('UTF-8');
...
$b = mb_strtolower($a);
echo $b;
Answer：
i have found this solution from here
$string = 'Թ';
echo 'Uppercase: '.mb_convert_case($string, MB_CASE_UPPER, "UTF-8").'';
echo 'Lowercase: '.mb_convert_case($string, MB_CASE_LOWER, "UTF-8").'';
echo 'Original: '.$string.'';
works for me (lower case)
Answer：
Have you tried
http://www.php.net/manual/en/function.mb-strtolower.php
mb_strtolower() and specifying the encoding as the second parameter?
The examples on that page appear to work.
You could also try:
$str = mb_strtolower($str, mb_detect_encoding($str));
Answer：
Php by default does not know about utf-8. It assumes any string is ASCII, so it strtolower converts bytes containing codes of uppercase letters A-Z to codes of lowercase a-z. As the UTF-8 non-ascii letters are written with two or more bytes, the strtolower converts each byte separately, and if the byte happens to contain code equal to letters A-Z, it is converted. In the result the sequence is broken, and it no longer represents correct character.
To change this you need to configure the mbstring extension:
http://www.php.net/manual/en/book.mbstring.php
to replace strtolower with mb_strtolower or use mb_strtolower direclty. I any case, you need to spend some time to configure the mbstring settings to match your requirements.
Answer：
Use mb_strtolower instead, as strtolower doesn’t work on multi-byte characters.
Answer：
strtolower() will perform the conversion in the currently selected locale only.
I would try mb_convert_case(). Make sure you explicitly specify an encoding.
Answer：
You will need to set the locale; see the first example at http://ca3.php.net/manual/en/function.strtolower.php
