php 中解决json中文乱码的函数

encode json php Chinese Garbled characters function deal with Tutorial data of Bring your own solve

php教程自带了json_encode来处理json数据,那么它们对中文的支持不好,下面我们来看个实例

echo json_encode(array(123213,'中国'));


{"platformid":"123213","userid":"1023","username":"u00b7u00f0u00b5u00b2u00c9u00b1u00b7u00f0u00ccu00fc"}

我们会发现,英文可以正确解析,但中文就出来u00b7u00f0u00b5u00b2u00c9u00b1u00b7u00f0u00ccu00fc哦,这可能是unicode编码,但我没测试过只是自己猜的。下面我们来看一款解决json中文乱码的函数

private function to_utf8($in)
{
if (is_array($in)) {
foreach ($in as $key => $value)
{
$out[$this->to_utf8($key)] = $this->to_utf8($value);
}
}
elseif(is_string($in))
{
if(mb_detect_encoding()($in) != "utf-8")
return utf8_encode($in);
else
return $in;
}
else
{
return $in;
}
return $out;
}

1.把$usr->username直接输出,页面头设置charset=utf-8.乱码
2.echo json_encode($usr)输出username=null
3.页面头设置为charset=gbk,输出正确->可以确定原编码为gbk
最后通过ie,chrome,firefox测试得出结论:


1.保证页面字符集与数据库教程一致,输出一定正常 。
2.做json_encode时保证数据编码是utf-8,json_decode正常。
3.如果要对非utf-8字符做json_encode,先转换成utf-8。
4.对非utf-8字符做json_decode的时候,千万不能忘记转换成原先的编码,否则会输出乱码!!
