php json_encode不支持gbk gb2312編碼的處理方法

php json_encode只支持utf-8編碼，自定義一個函數便可解決之：

 

public function my_json_encode(array $data) {
        $s= array();
        foreach($data as $k => $v) {
            if(is_array($v)) {
                $v = my_json_encode($v);
                $s[] = "\"$k\":$v";
            }else{
                $v = addslashes( str_replace( array("\n","\r"), '', $v));
                $s[] = "\"$k\": \"$v\"";
            }
        }
        return '{'.implode(', ', $s).'}';
    }
