How can I convert an array like this to an object?

[128] => Array
    (
        [status] => "Figure A.
 Facebook's horizontal scrollbars showing up on a 1024x768 screen resolution."
    )

[129] => Array
    (
        [status] => "The other day at work, I had some spare time"
    )

This one worked for me

  function array_to_obj($array, &$obj)
  {
    foreach ($array as $key => $value)
    {
      if (is_array($value))
      {
      $obj->$key = new stdClass();
      array_to_obj($value, $obj->$key);
      }
      else
      {
        $obj->$key = $value;
      }
    }
  return $obj;
  }

function arrayToObject($array)
{
 $object= new stdClass();
 return array_to_obj($array,$object);
}

usage :

$myobject = arrayToObject($array);
print_r($myobject);

returns :

    [127] => stdClass Object
        (
            [status] => Have you ever created a really great looking website design
        )

    [128] => stdClass Object
        (
            [status] => Figure A.
 Facebook's horizontal scrollbars showing up on a 1024x768 screen resolution.
        )

    [129] => stdClass Object
        (
            [status] => The other day at work, I had some spare time
        )

like usual you can loop it like:

foreach($myobject as $obj)
{
  echo $obj->status;
}

You can have the class implement the ArrayAccess interface. This will allow you to treat the object like an array without casting and you get total control over how the members are used.

A quick way to do this is:

$obj = json_decode(json_encode($array));

Explanation

json_encode($array) will convert the entire multi-dimensional array to a JSON string. (php.net/json_encode)

json_decode($string) will convert the JSON string to a stdClass object. If you pass in TRUE as a second argument to json_decode, you'll get an associative array back. (php.net/json_decode)

I don't think the performance here vs recursively going through the array and converting everything is very noticeable, although I'd like to see some benchmarks of this. It works, and it's not going to go away.

If you could index the array by gear or some unique value, it would be a lot easier.

$indexed = array();

// create an array using 'gear' as the index
foreach($arrayValue as $value) {
    $indexed[$value['gear']] = $value;
}

// loop over each object
foreach($objectArray as $obj) {
    $value = $indexed[$obj->gear]; // find the corresponding array
    foreach($value as $name => $val) {
        $obj->$name = $val; // assign each array index/value pair to the object
    }
}

If possible to get your code to return the array with the index by default, you can remove the first foreach loop.

Hope that helps.

References to the same objects already get copied when you copy the array. But it sounds like you want to shallow-copy deep-copy the objects being referenced in the first array when you create the second array, so you get two arrays of distinct but similar objects.

The most intuitive way I can come up with right now is a loop; there may be simpler or more elegant solutions out there:

$new = array();

foreach ($old as $k => $v) {
    $new[$k] = clone $v;
}
