array of arrays to array of objects php - php

Question

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.

Answer 1

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.

Answer 2

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"
}
}

Answer 3

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

Answer 4

You have an indexed array of associative arrays. If you convert it to json then back to an iterable state with the default behavior of json_decode(), the top level (indexed array) will be cast as array-type while the subarrays will become object-type.
Note that this will conversion will permeate all the way through subsequent levels of data (in case researchers might have deeper data structures). Effectively, indexed arrays remain indexed arrays and associative arrays become objects.
This is such a basic call that I am not sure that creating a wrapper for it is necessary.
Code: (Demo)
$assoc = array (
array(
'prop1'=>'val1',
'prop2'=>'val2',
),
array(
'prop1'=>'val1',
'prop2'=>'val2',
),
);
var_export(
json_decode(json_encode($assoc))
);
Output:
array (
0 =>
(object) array(
'prop1' => 'val1',
'prop2' => 'val2',
),
1 =>
(object) array(
'prop1' => 'val1',
'prop2' => 'val2',
),
)
