php字符串编码转换程序_PHP教程

echo $str= '你好,这里是卖咖啡!';
echo '
';

echo iconv('GB2312', 'UTF-8', $str); //将字符串的编码从GB2312转到UTF-8
echo '
';

echo iconv_substr($str, 1, 1, 'UTF-8'); //按字符个数截取而非字节
print_r(iconv_get_encoding()); //得到当前页面编码信息

echo iconv_strlen($str, 'UTF-8'); //得到设定编码的字符串长度

//也有这样用的

$content = iconv("UTF-8","gbk//TRANSLIT",$content);
?>

function phpcharset($data, $to) {
if(is_array($data)) {
foreach($data as $key => $val) {
$data[$key] = phpcharset($val, $to);
}
} else {
$encode_array = array('ASCII', 'UTF-8', 'GBK', 'GB2312', 'BIG5');
$encoded = mb_detect_encoding($data, $encode_array);
$to = strtoupper($to);
if($encoded != $to) {
$data = mb_convert_encoding($data, $to, $encoded);
}
}

}
?>
