Solve the problem of php Chinese garbled code conversion

Solution to php Chinese garbled code conversion: 1. Set the encoding to "header('Content-Type: text/html; charset=utf-8');"; 2. Use functions such as "mb_convert_encoding" to perform Convert.

PHP code Chinese output garbled code and transcoding issues

1.header('Content-Type:text/html;charset=utf-8'); To prevent Chinese garbled output in json format, write this line of code before output

2. Character transcoding: $a is the string to be transcoded, $encode is the encoding rule of $a, $to_encode is the encoding rule that $a will be converted to, $str_encode is the transcoded string,

（一）： $encode = mb_detect_encoding($a, array("ASCII", 'UTF-8', "GB2312", "GBK", 'BIG5'));//获取当前字符串的编码
$str_encode = mb_convert_encoding($a, $to_encode, $encode);//将字符编码改为$to_encode
（二）：$str_encode = iconv($encode, $to_encode, $a);//例：$A = iconv("gbk", "utf-8", $A);
（三）：/**
 * 1.自动识别编码并转换为UTF-8
 */
function characet($data){
  if( !empty($data) ){   
    $fileType = mb_detect_encoding($data , array('UTF-8','GBK','LATIN1','BIG5')) ;  
    if( $fileType != 'UTF-8'){  
      $data = mb_convert_encoding($data ,'utf-8' , $fileType);  
    }  
  }  
  return $data;   
}

3. I wrote a small code that handles PHP code and outputs Chinese characters during http debugging:

//防止中文转码，遍历数据结果，每项单独urlencode，
    public function arrayUrlencode($array) {
        if (empty($array)) {
            return $array;
        } else {
            foreach ($array as $key =>$value) {//对每个数组元素进行urlencode
                if (is_array($value)) {
                    $array[$key] =$this->arrayUrlencode($value);
                } else {
                    $array[$key] =urlencode($value);
                }
            }
        }
        return $array;
    }
 
    //再整体urldecode
    public function arrayJsonencode($array) {
        $url_arr =$this->arrayUrlencode($array);
        $json_arr = json_encode($url_arr);//json 输出
        return urldecode($json_arr); //整体urldecode
}
