I am trying to convert the associative array to an array of objects.

$assoc = array (
array(
    'prop1'=>'val1',
    'prop2'=>'val2',
),

array(
    'prop1'=>'val1',
    'prop2'=>'val2',
),
)

Here Is the code I have so far:

class Assoc {
public function setObject($assoc) {
    $this->assoc[] = new Obj($assoc);
}
}
class Obj {
public function __construct($item) {
    foreach ( $item as $property=>$value ) {
        $this->{$property} = $value;
    }
}
}

$test = New Assoc();
$test->setObject($assoc);

This code will work for a single array but not an array of arrays. If you could help with what I believe to be the loop in the setObject function.

What is $input? Where is it defined? –  FakeRainBrigand Jan 14 '12 at 6:38
    
Sorry, in trying to generalize the code I missed changing a few vars. They are both $assoc and updated in the post. –  Matthew Sprankle Jan 14 '12 at 6:41

EDIT for specific object:

To adhere to your existing style as close as possible without messing with array_map voodoo:

class Assoc {
  public function setObject($assoc) {
    foreach ($assoc as $arr) {
      $this->assoc[] = new Obj($arr);
    }   
  }
}
class Obj {
   public function __construct($item) {
     foreach ( $item as $property=>$value ) { 
       $this->{$property} = $value;
     }  
   }   
}

$test = New Assoc();
$test->setObject($assoc);

Original:

If you just need generic conversion, and not into specific custom objects (not exactly clear in your post?) you can try this:

$new_array = array();
foreach ($assoc as $to_obj)
{
  $new_array[] = (object)$to_obj;
}

// Print results
var_dump($new_array);

outputs:

array(2) {
  [0]=>
  object(stdClass)#1 (2) {
    ["prop1"]=>
    string(4) "val1"
    ["prop2"]=>
    string(4) "val2"
  }
  [1]=>
  object(stdClass)#2 (2) {
    ["prop1"]=>
    string(4) "val1"
    ["prop2"]=>
    string(4) "val2"
  }
}

I am looking for similar output into a Specific object. –  Matthew Sprankle Jan 14 '12 at 6:56
    
I am trying: foreach ($assoc as $to_obj) { $this->assoc[] = new Obj($to_obj); } But am getting invalid argument supplied for foreach –  Matthew Sprankle Jan 14 '12 at 7:01
    
array_map is considered "voodoo"? –  Joshua K Jan 14 '12 at 8:14

$len = count($assoc);
for($i=0;$i<$len; $i++){
    $assoc[$i] = (Object)$assoc[$i];
}

Convert the associative array to an array of objects:

$output = array_map(function($element) {
    return (object) $element;
}, $assoc);

Simple enough.

EDIT: If you need to make objects of a specific class:

$output = array_map(function($element) use ($classType) {
    return new $classType($element);
}, $assoc);

You can generalize it into just about anything, really.

Note Ending code is public function setInput($assoc) { $this->assoc= array_map(function($item){return new Input($item);}, $assoc); } –  Matthew Sprankle Jan 14 '12 at 7:39
    
You really, really, don't need classes for this. PHP already has two types of arrays: a built-in one and SPL "fixed" arrays. Use the first if you need hash-table semantics, and the second if you need fixed-size arrays. Don't create your own wrapper. –  Joshua K Jan 14 '12 at 7:58
    
.... two downvotes? really? –  Joshua K Jan 22 '12 at 6:42
