php move nodes to parent array - php

Question

How could I move all nodes of the 'fields' array into its parent array '113', whilst unsetting 'fields' ?
[a] => Array
(
[113] => Array
(
[title] => asdfasdfas
[alias] => asdfasdfas
[fields] => Array
(
[jr_streetaddress] => Array
(
[type] => text
[label] => Street Address
[data] => asdfasdffsd
)
[jr_towncity] => Array
(
[type] => text
[label] => Town / City
[data] => Nottingham
)
)
)
)

Answer 1

Assuming your top level array ($something['a']) is the variable $a:
foreach($a as $key => $values){
if(isset($values['fields']))
{
$a[$key] = array_merge($a[$key], (array) $values['fields']);
unset($a[$key]['fields']);
}
}
Alternatively, if you dont want to hit every array element in $a you can just remove the loop and substitute $values with $a[113] and $key with 113.
Also note the casting for the fields element to an array, jsut in case it isnt one with (array) $values['fields']

If you can make this array like this:
[a] => Array
(
[113] => Array
(
[title] => asdfasdfas
[alias] => asdfasdfas
[jr_streetaddress] => Array
(
[type] => text
[label] => Street Address
[data] => asdfasdffsd
)
[jr_towncity] => Array
(
[type] => text
[label] => Town / City
[data] => Nottingham
)
)
)
try to use this code:
$array['a'][113]['jr_streetaddress'] = $array['a'][113]['fields']['jr_streetaddress'];
$array['a'][113]['jr_towncity'] = $array['a'][113]['fields']['jr_towncity'];
unset($array['a'][113]['fields']);
