My PHP Loop is below
foreach ($retr as $page) {
echo $page['name'];
//var_dump($page);
}

Your array is multidimentional, being a single element array containing a further 19 child elements.
If you just want to itterate the child elements, then run the loop over the top level elelemt, not the parent array:
foreach ($retr[0] as $page) {...}

you must echo this variable
$data[0][0]['message']

If you can't change it at the source then here is one way (PHP >= 5.5.0 needed for array_column):
foreach($design_values as $key => $values) {
$result[$key] = array_combine(
array_column($values, 'name'),
array_column($values, 'value'));
}
Or possibly, and easier:
foreach($design_values as $key => $values) {
$result[$key] = array_column($values, 'value', 'name');
}
Our use the PHP Implementation of array_column

You should probably create the array you want when making the first array, but if you don't have control over that and just want to conver then something like this should work:
$newArray = array();
foreach($oldArray as $row){
$tmp = array();
foreach($row as $values){
$tmp[$values['name']] = $values['value'];
}
$newArray[] = $tmp;
}
print_r($newArray);

parent-child tree in select box

The following code will recurse through your data structure and create the list of options. I will leave the creation of the select tag to you, since it is very simple. I've used PHP_EOL to add line breaks after each option to make the HTML code easier to read.
foreach ($data['categories'] as $c) {
# scope is $c['scope']
echo "Starting " . $c['scope'] . PHP_EOL;
# calling the function on the categories data
recurse($c['categories']);
echo "Finished " . $c['scope'] . PHP_EOL;
}
function recurse($arr, $level = 0){
# we have a numerically-indexed array. go through each item:
foreach ($arr as $n) {
# print out the item ID and the item name
echo '<option value="' . $n['id'] . '">'
. str_repeat("-", $level)
. $n['name']
. '</option>'
. PHP_EOL;
# if item['children'] is set, we have a nested data structure, so
# call recurse on it.
if (isset($n['children'])) {
# we have children: RECURSE!!
recurse( $n['children'], $level+1);
}
}
}
Output:
Starting selectboxFirst
<option value="4001">Access</option>
<option value="4010">-mine</option>
<option value="4011">-yours</option>
<option value="4002">Communication</option>
<option value="4015">-Physician</option>
<option value="4016">--Helps blsys Understand</option>
<option value="4017">--Listens</option>
<option value="4021">-Clinical ps</option>
<option value="4022">--yours ps/datasssss</option>
<option value="4024">-etc</option>
<option value="4003">Office</option>
<option value="4026">-Facilities/Environment</option>
<option value="4027">--Noise</option>
(etc.)
You can substitute the appropriate code for "Starting selectboxFirst/selectboxSecond".

CakePHP and Set::combine

I need to get the data for each language in it's field as an array.
Probably the best approach in CakePHP will be Set::combine but can't get it working.
I can do it manually with foreach but I don't think that will be the best way.
Here is the example:
Array
(
[Article] => Array
(
[id] => 131
[title] => TEST
)
[titleTranslation] => Array
(
[0] => Array
(
[id] => 62
[locale] => eng
[model] => Article
[foreign_key] => 131
[field] => title
[content] => TEST
)
[1] => Array
(
[id] => 63
[locale] => fre
[model] => Article
[foreign_key] => 131
[field] => title
[content] => Salva
)
[2] => Array
(
[id] => 64
[locale] => rus
[model] => Article
[foreign_key] => 131
[field] => title
[content] => Пвет
)
)
)
into this array:
Array
(
[Article] => Array
(
[id] => 131
[title] => Array
(
[eng] => TEST
[fre] => Salva
[rus] => Пвет
)
)
.... the rest is not important
)
Solved-----
$translatedData = Set::combine($this->data['titleTranslation'], '{n}.locale', '{n}.content', '{n}.field');
$this->data['Article'] = array_merge($this->data['Article'], $translatedData);
