Array to stdClass can be done in php this way   stdClass is already PHP s generic empty class    a   stdClass     set state array       Actually calling stdClass    set state   in PHP 5 will produce a fatal error  thanks  Ozzy for pointing out  This is an example of how you can use   set state   with a stdClass object in PHP5  class stdClassHelper       public static function   set state array  array            stdClass   new stdClass            foreach   array as  key   gt   value               stdClass- gt  key    value                    return  stdClass            newstd   stdClassHelper    set state array       Or a nicer way    a    object  array

The quick and dirty way is using json encode and json decode which will turn the entire array  including sub elements  into an object    clasa   json decode json encode  clasa      Turn it into an object   The same can be used to convert an object into an array  Simply add   true to json decode to return an associated array    clasa   json decode json encode  clasa   true     Turn it into an array     An alternate way  without being dirty  is simply a recursive function   function convertToObject  array         object   new stdClass        foreach   array as  key   gt   value            if  is array  value                  value   convertToObject  value                      object- gt  key    value            return  object      or in full code    lt  php     function convertToObject  array             object   new stdClass            foreach   array as  key   gt   value                if  is array  value                      value   convertToObject  value                              object- gt  key    value                    return  object              clasa   array               e1    gt  array  nume    gt   Nitu    prenume    gt   Andrei    sex    gt   m    varsta    gt  23                e2    gt  array  nume    gt   Nae    prenume    gt   Ionel    sex    gt   m    varsta    gt  27                e3    gt  array  nume    gt   Noman    prenume    gt   Alice    sex    gt   f    varsta    gt  22                e4    gt  array  nume    gt   Geangos    prenume    gt   Bogdan    sex    gt   m    varsta    gt  23                e5    gt  array  nume    gt   Vasile    prenume    gt   Mihai    sex    gt   m    varsta    gt  25               obj   convertToObject  clasa       print r  obj     gt    which outputs  note that there s no arrays - only stdClass s    stdClass Object        e1    gt  stdClass Object                        nume    gt  Nitu              prenume    gt  Andrei              sex    gt  m              varsta    gt  23                 e2    gt  stdClass Object                        nume    gt  Nae              prenume    gt  Ionel              sex    gt  m              varsta    gt  27                 e3    gt  stdClass Object                        nume    gt  Noman              prenume    gt  Alice              sex    gt  f              varsta    gt  22                 e4    gt  stdClass Object                        nume    gt  Geangos              prenume    gt  Bogdan              sex    gt  m              varsta    gt  23                 e5    gt  stdClass Object                        nume    gt  Vasile              prenume    gt  Mihai              sex    gt  m              varsta    gt  25                So you d refer to it by  obj- gt e5- gt nume   DEMO

To convert array to object using stdClass just add  object  to array u declare   EX   echo  array  value    echo  object- gt value    to convert object to array   obj    object  array    to convert array to object   arr    array  object   with these methods you can swap between array and object very easily     Another method is to use json   object   json decode json encode  array   FALSE     But this is a much more memory intensive way to do and is not supported by versions of PHP  lt   5 1
