How to merge 2 arrays - nest one array into another

Question

I have an array:

$form['info'] = array(...);
$form['container'] = array(...);

and I have another array:

$container['item_1'] = array(...);
$container['item_2'] = array(...);

I would like to get a structure like this:

$form['info']
$form['container']['...']
$form['container']['item_1']
$form['container']['item_2']

How could I merge $form and $container array to achieve this? I need to nest/add all items from $container array into $form['container'] variable. array_merge() does not seems to work this way.

What code (exactly) are you using in attempt to merge? Could you supply source? — BlitZ

The source is too complicated so I made this simple example. — Incredible

$form['container']['item_1'] it will give you merged array with container and item1 values. right? — RJParikh

Why array_merge() is not working? Your task is to merge $form['container'] with $container as I understand. array_merge() can handle this.

$form['container'] = array_merge($form['container'], $container);

This should handle it:

foreach($container as $key => $value){
    $form['container'][$key] = $value;
}

Iterate your $containerand get its key-vaule-pairs
Append them to your $form

Thanks, this works. I think there is no native php function for this kind of merging.

Use this

<?php
$form["info"] = array('info');
$form["container"] = array('container');
$container['item_1'] = array('1');
$container['item_2'] = array('2');

foreach($container as $k=>$f)
{
    $form['container'][$k] = $f;
}
print_r($form);
?>
