本文實例講述了PHP讀取文件,解決中文亂碼UTF-8的方法。分享給大家供大家參考，具體如下：

$opts = array( 'file' => array( 'encoding' => "utf-8" ));$opts = array('http' => array('encoding' => 'utf-8'));$ctxt = stream_context_create($opts);$content = file_get_contents($filePath, FILE_TEXT, $ctxt); |
最簡單的就是將GF2312→UTF-8
|
1
|
$str = iconv("gb2312", "utf-8", $str); |
不管用的
|
1
|
$content = mb_convert_encoding($content, "UTF-8", "auto"); |
******************************************丑陋的分割線來告訴大家上面的不好的：下面的才是正確的方法···哈哈···**********************************************************

以上的終極版·可以適應中文操作windows系統建立的ANSI``````````````UTF-8`````````Unicode`````的txt文本····
希望本文所述對大家PHP程序設計有所幫助。
