Hi,
I try to detect the encoding type of a string $myString which comes
from a html file.
$myString = file_get_contents($myFileName);
Firstly : I tried to get the charset in <meta charset="iso-8859-1">.
But I've the following problem. Internet Explorer write ISO-8859-1 even
if we have save it in Unicode format (UTF-16).
Secondly : Use a algorithm which detect encoding format
w3 has proposed this one which detect utf-8 format
<?php
// Returns true if $string is valid UTF-8 and false otherwise.
function is_utf8($string) {
// From
http://w3.org/International/question...rms-utf-8.html
return preg_match('%^(?:
[\x09\x0A\x0D\x20-\x7E] # ASCII
| [\xC2-\xDF][\x80-\xBF] # non-overlong 2-byte
| \xE0[\xA0-\xBF][\x80-\xBF] # excluding overlongs
| [\xE1-\xEC\xEE\xEF][\x80-\xBF]{2} # straight 3-byte
| \xED[\x80-\x9F][\x80-\xBF] # excluding surrogates
| \xF0[\x90-\xBF][\x80-\xBF]{2} # planes 1-3
| [\xF1-\xF3][\x80-\xBF]{3} # planes 4-15
| \xF4[\x80-\x8F][\x80-\xBF]{2} # plane 16
)*$%xs', $string);
} // function is_utf8
?>
I want the same but foe utf-16 type, does it exist?
mb_detect_encoding($ma_chaine,"UTF-16") doesn't work with utf-16.
The must : detect encoding type without knowing the name and the
version of the navigator.
Thanks a lot.
