Problems with merging arrays - php

Question

I have a number of arrays like the one below. These are the result of data retrieved from the database. I need the final array to have the structure mentioned because I need to foreach loop each 'notes' in the successive code. I can't use a for loop only.
array('title' => 'Testing',
'content' => 'some text',
'created' => 'time',
'tags' => array(array('title' => 'hello')),
)
array('title' => 'Testing',
'content' => 'some text',
'created' => 'time',
'tags' => array(array('title' => 'hello')),
)
I want to merge all of these in an array of the format:
array(
array('notes' =>
array('title' => 'Testing',
'content' => 'some text',
'created' => 'time',
'tags' => array(array('title' => 'hello')),
),
),
array('notes' =>
array('title' => 'Testing',
'content' => 'some text',
'created' => 'time',
'tags' => array(array('title' => 'hello')),
),
),
);
I've tried many PHP functions but none gave me the result I want. Can someone help me please? Is there a built-in PHP function that can do this? Can someone show me an example.
Thanks.

Answer 1

If I'm understanding your question correctly, all you actually want to do is place each of your array elements into another array with the key notes and the value being that of the element (another array).
In which case either using foreach or array_map will do.
$newArray = array_map(function($v) { return ['notes' => $v]; }, $array);
Or using foreach (the more verbose way)...
foreach($array as $value) {
$newArray[] = ['notes' => $value];
}

this is a comment i want the formatting...
You have asked for an 'array' of 'array entries' where each entry
is an array
each array has a key of 'notes' and an associated data array.
I think the 'tags' part of you structure would be easier to use without the extra level of 'nesting'.
Here is the code to create and display the 'wanted' output with the 'tag' entry changed:
$wanted = array(
array('notes' =>
array('title' => 'Testing 1',
'content' => 'some text 1',
'created' => date('Y-m-d H:i:s'),
'tags' => array('title' => 'hello',
'tagFoo' => 'foo' ),
),
),
array('notes' =>
array('title' => 'Testing 2',
'content' => 'some text 2',
'created' => date('Y-m-d H:i:s'),
'tags' => array('title' => 'hello',
'tagBar' => 'bar'),
),
),
);
echo '<pre>';
print_r($wanted);
echo '</pre>';
Here is the output:
Array
(
[0] => Array
(
[notes] => Array
(
[title] => Testing 1
[content] => some text 1
[created] => 2015-01-04 15:39:34
[tags] => Array
(
[title] => hello
[tagFoo] => foo
)
)
)
[1] => Array
(
[notes] => Array
(
[title] => Testing 2
[content] => some text 2
[created] => 2015-01-04 15:39:34
[tags] => Array
(
[title] => hello
[tagBar] => bar
)
)
)
)

one possibilyti is to do:
foreach($tags as $key => $note){
$note["created"] = $created[$key]; //if created is an array
$note["created"] = $created; //if created is a string
}
