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;
}
