php自动获取字符串编码函数mb_detect_encoding
[ 2017-06-03 14:19:16 | 作者: admin ]
当在php中使用mb_detect_encoding函数进行编码识别时，很多人都碰到过识别编码有误的问题，例如对与GB2312和UTF- 8，或者UTF-8和GBK(这里主要是对于cp936的判断),网上说是由于字符短是，mb_detect_encoding会出现误判。
例如:
例如:
$encode = mb_detect_encoding($keytitle, array("ASCII","GB2312′,'UTF-8′,"GBK",'BIG5′));
if ($encode == “UTF-8″){
$keytitle = iconv("UTF-8″,"GB2312//IGNORE",$keytitle);
}
if ($encode == “UTF-8″){
$keytitle = iconv("UTF-8″,"GB2312//IGNORE",$keytitle);
}
