PHP读取文件,解决中文乱码UTF

本文实例讲述了php读取文件,解决中文乱码utf-8的方法。分享给大家供大家参考，具体如下：

$opts = array(  'file' => array(    'encoding' => "utf-8"  ));$opts = array('http' => array('encoding' => 'utf-8'));$ctxt = stream_context_create($opts);$content = file_get_contents($filepath, file_text, $ctxt);

最简单的就是将gf2312→utf-8

$str = iconv("gb2312", "utf-8", $str);

不管用的

$content = mb_convert_encodi重庆大专排名ng($content, "utf-8", "auto");
