file_put_contents 写入文件,json,ajax中文乱码解决

cms网站是gb2312的,但是json,ajax等用法,只要涉及中文时,都要求是utf-8编码,所以,必须在php中就要进行转码.  
转码后的文本发送到gb2312编码的html页面时, 你不必担心在网页中乱码问题..  
如果不确定你的原始内容是什么编码,可以这样检测

$encode = mb_detect_encoding($new, array("ASCII",'UTF-8',"GB2312","GBK",'BIG5')); //php

如果返回euc-cn 说明是gb2312的.用file\_put\_contents写入文件时,建议用以下函数进行转码.例如

file_put_contents('123.txt', charsetToUTF8($new));

以下是转码函数

/** * 将非GBK字符集的编码转为GBK * * @param mixed $mixed 源数据 * * @return mixed GBK格式数据 */
    function charsetToGBK($mixed) { 
        if (is_array($mixed)) {
            foreach ($mixed as $k => $v) {
                if (is_array($v)) {
                    $mixed[$k] = charsetToGBK($v);
                } else {
                    $encode = mb_detect_encoding($v, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
                    if ($encode == 'UTF-8') {
                        $mixed[$k] = iconv('UTF-8', 'GBK', $v);
                    }
                }
            }
        } else {
            $encode = mb_detect_encoding($mixed, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
            //var_dump($encode);
            if ($encode == 'UTF-8') {
                $mixed = iconv('UTF-8', 'GBK', $mixed);
            }
        }
        return $mixed;
    }
    
    
    /** * 将非UTF-8字符集的编码转为UTF-8 * * @param mixed $mixed 源数据 * * @return mixed utf-8格式数据 */
    function charsetToUTF8($mixed) { 
        if (is_array($mixed)) {
            foreach ($mixed as $k => $v) {
                if (is_array($v)) {
                    $mixed[$k] = charsetToUTF8($v);
                } else {
                    $encode = mb_detect_encoding($v, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
                    if ($encode == 'EUC-CN') {
                        $mixed[$k] = iconv('GBK', 'UTF-8', $v);
                    }
                }
            }
        } else {
            $encode = mb_detect_encoding($mixed, array('ASCII', 'UTF-8', 'GB2312', 'GBK', 'BIG5'));
            if ($encode == 'EUC-CN') {
                $mixed = iconv('GBK', 'UTF-8', $mixed);
            }
        }
        return $mixed;
    }
