In the simplest case  it s probably sufficient to  cast  the array as an object    object    object   array    Another option would be to instantiate a standard class as a variable  and loop through your array while re-assigning the values    object   new stdClass    foreach   array as  key   gt   value         object- gt  key    value      As Edson Medina pointed out  a really clean solution is to use the built-in json  functions    object   json decode json encode  array   FALSE     This also  recursively  converts all of your sub arrays into objects  which you may or may not want  Unfortunately it has a 2-3x performance hit over the looping approach   Warning   thanks to Ultra for the comment       json decode on different enviroments converts UTF-8 data in different ways  I end up getting on of values  240 00  locally and  240  on production - massive dissaster  Morover if conversion fails string get s returned as NULL

Using json encode is problematic because of the way that it handles non UTF-8 data  It s worth noting that the json encode json encode method also leaves non-associative arrays as arrays  This may or may not be what you want  I was recently in the position of needing to recreate the functionality of this solution but without using json  functions  Here s what I came up with          Returns true if the array has only integer keys     function isArrayAssociative array  array        return  bool count array filter array keys  array    is string               Converts an array to an object  but leaves non-associative arrays as arrays      This is the same logic that  json decode json encode  arr   false   uses      function arrayToObject array  array   maxDepth   10        if  maxDepth    0            return  array             if isArrayAssociative  array              newObject   new  stdClass          foreach   array as  key   gt   value                if is array  value                      newObject- gt   key    arrayToObject  value   maxDepth - 1                 else                    newObject- gt   key     value                                  return  newObject        else             newArray   array            foreach   array as  value                if is array  value                      newArray     arrayToObject  value   maxDepth - 1                 else                    newArray      value                                                  return  newArray

There s no built-in method to do it as far as I m aware  but it s as easy as a simple loop        obj  new stdClass         foreach   array as  k  gt   v             obj- gt   k     v          You can expound on that if you need it to build your object recursively

Little complicated but easy to extend technique   Suppose you have an array    a           name    gt   ankit         age    gt   33         dob    gt   1984-04-12       Suppose you have have a Person class which may have more or less attributes from this array  for example  class Person        private  name      private  dob      private  age      private  company      private  city      If you still wanna change your array to the person object  You can use ArrayIterator Class     arrayIterator   new  ArrayIterator  a      Pass your array in the argument    Now you have iterator object    Create a class extending FilterIterator Class  where you have to define the abstract method accept  Follow the example  class PersonIterator extends  FilterIterator       public function accept                 return property exists  Person   parent  current               The above impelmentation will bind the property only if it exists in the class    Add one more method in the class PersonIterator  public function getObject Person  object            foreach   this as  key   gt   value                         object- gt   set    underscoreToCamelCase  key    value                     return  object      Make sure you have mutators defined in your class   Now you are ready to call these function where you want to create object    arrayiterator   new  ArrayIterator  a    personIterator   new  PersonIterator  arrayiterator     personIterator- gt getObject       this will return your Person Object

You could also use an ArrayObject  for example    lt  php      arr   array  test                    array  one   gt 1  two   gt 2  three   gt 3                     array  one   gt 1  two   gt 2  three   gt 3                     o   new ArrayObject  arr       echo  o- gt offsetGet 2   two     n       foreach   o as  key  gt  val           if  is array  val                 foreach  val as  k   gt   v                   echo  k       gt       v   n                                   else                          echo  val   n                     gt     Output    2   test   one   gt  1   two   gt  2   three   gt  3   one   gt  1   two   gt  2   three   gt  3

Depending on where you need that and how to access the object there are different ways to do it   For example  just typecast it   object     object   yourArray    However  the most compatible one is using a utility method  not yet part of PHP  that implements standard PHP casting based on a string that specifies the type  or by ignoring it just de-referencing the value           dereference a value and optionally setting its type        param mixed  mixed     param null   type  optional         return mixed  mixed set as  type     function rettype  mixed   type   NULL         type     NULL    settype  mixed   type       return  mixed      The usage example in your case  Online Demo     yourArray   Array  status    gt   Figure A          echo rettype  yourArray   object  - gt status     prints  Figure A

I would definitly go with a clean way like this     lt  php  class Person      private  name    private  age    private  sexe     function   construct   payload           if  is array  payload              this- gt from array  payload           public function from array  array           foreach get object vars  this  as  attrName   gt   attrValue           this- gt   attrName     array  attrName          public function say hi             print  hi my name is   this- gt name           print r   POST    mike   new Person   POST    mike- gt say hi       gt    if you submit     you will get this     I found this more logical comparing the above answers from Objects should be used for the purpose they ve been made for  encapsulated cute little objects    Also using get object vars ensure that no extra attributes are created in the manipulated Object  you don t want a car having a family name  nor a person behaving 4 wheels

Obviously just an extrapolation of some other folks  answers  but here s the recursive function that will convert any mulch-dimensional array into an object      function convert array to object  array          obj  new stdClass          foreach   array as  k  gt   v             if  is array  v                 v   convert array to object  v                           obj- gt  strtolower  k      v                return  obj         And remember that if the array had numeric keys they can still be referenced in the resulting object by using     for instance   obj- gt prop- gt  4 - gt prop
