For more solution i have completed the solution of  the great  Tiago Gouv  a exposed before only for strings and arrays   i used md convert encoding   function instead of utf8 encode    it works for me    12 hours loosed          this object return me a big array who have multiple arrays imbricated   get days   program  get days  ARR   client        and i use this function for well parsing what the server return                                    function convert to utf8 recursively  dat                         if  is string  dat                              return mb convert encoding  dat   UTF-8    UTF-8                                                  elseif  is array  dat                               ret                                foreach  dat as  i   gt   d                               ret  i    convert to utf8 recursively  d                                                       return  ret                                                else                           return  dat                                                                use                   data   convert to utf8 recursively  get days      what the server return   i talk to that because i test the same code in two different servers  the first return me a well formatted json   without any function  as we usually do BUT the second server does not send me back anything if I do not apply this function

I wrote this method to handle UTF8 arrays and JSON problems  It works fine with array  simple and multidimensional           Encode array from latin1 to utf8 recursively     param  dat     return array string        public static function convert from latin1 to utf8 recursively  dat             if  is string  dat              return utf8 encode  dat           elseif  is array  dat               ret                foreach   dat as  i   gt   d   ret   i     self  convert from latin1 to utf8 recursively  d             return  ret          elseif  is object  dat              foreach   dat as  i   gt   d   dat- gt  i   self  convert from latin1 to utf8 recursively  d             return  dat          else            return  dat                  Sample use    Just pass your array or string and the UTF8 encode will be fixed  data   convert from latin1 to utf8 recursively  data
