PHP new array()

Question

$var is an array:

Array (
 [0] => stdClass Object ( [ID] => 113 [title] => text )
 [1] => stdClass Object ( [ID] => 114 [title] => text text text )
 [2] => stdClass Object ( [ID] => 115 [title] => text text )
 [3] => stdClass Object ( [ID] => 116 [title] => text )
)

Want to update it in two steps:

• Get [ID] of each object and throw its value to position counter (I mean [0], [1], [2], [3])
• Remove [ID] after throwing

Finally, updated array ($new_var) should look like:

Array (
 [113] => stdClass Object ( [title] => text )
 [114] => stdClass Object ( [title] => text text text )
 [115] => stdClass Object ( [title] => text text )
 [116] => stdClass Object ( [title] => text )
)

How to do this?

Thanks.

Answer 1

I'd have thought this would work (have no interpreter access, so it might require tweaking):

<?php

    class TestObject {
        public $id;
        public $title;

        public function __construct($id, $title) {

            $this->id = $id;
            $this->title = $title;

            return true;
        }
    }

    $var = array(new TestObject(11, 'Text 1'), 
                 new TestObject(12, 'Text 2'),
                 new TestObject(13, 'Text 3'));
    $new_var = array();

    foreach($var as $element) {
        $new_var[$element->id] = array('title' => $element->title);
    }

    print_r($new_var);

?>

Incidentally, you might want to update your variable naming conventions to something more meaningful. :-)

Answer 2

$new_array = array();
foreach ($var as $object)
{
  $temp_object = clone $object;
  unset($temp_object->id);
  $new_array[$object->id] = $temp_object;
}

I'm making the assumption that there is more in your objects and you just want to remove ID. If you just want the title, you don't need to clone to the object and can just set $new_array[$object->id] = $object->title.
