How to perform array manipulation - arrays

I have an array like this from cdbcommand select query. (Using Yii)
Array(
[0] => Array(
[0] => Array
(
[id] => 21
)
[1] => Array
(
[id] => 91
)
[2] => Array
(
[id] => 125
)
)
[1] => Array
(
[0] => Array
(
[id] => 15
)
)
)
I want final array like array(21, 91, 125, 15)
How can I do this?

$output=array();
foreach($result as $row){
foreach($row as $id_container){
$output[]=$id_container["id"];
}
}
This will give you what you need, if array structure is dependable - then it wont work.

try this
$newArray=array();
foreach($result as $value)
{
array_merge($newArray,array_values($value));
}

rearrange php multidimensional array according to id

-I cannot figure out how to regroup this array accourding to ids.
This array comes from a mysql table. the number 17 and 20 are foreign keys in the table.
$orginal_arr =
Array
(
[0] => Array
(
[id] => 17
[content] => string...?
)
[1] => Array
(
[id] => 20
[content] => hello
)
[2] => Array
(
[id] => 20
[content] => string...?
)
[3] => Array
(
[id] => 20
[content] => string...string...??
)
[4] => Array
(
[id] => 17
[content] => string...
)
[5] => Array
(
[id] => 17
[content] => string...
)
);
I want to convert the above $orginal_arr array to the following $desired_arr array.
$desired_arr = Array (
[0] => Array
(
[17] => Array
(
[0] => string...?
)
)
[1] => Array
(
[20] => Array
(
[0] => hello
[1] => string...?
[2] => string... string...??
)
)
[2] => Array
(
[17] => Array
(
[0] => string...
[1] => string...
)
)
);
so far I am trying the following approach:
function group_by_key($key, $data)
{
$result = array();
$j = 0;
foreach ($data as $val) {
if (array_key_exists($key, $val)) {
$result[$val[$key]][$j] = $val;
} else {
$result[""][] = $val;
}
$j++;
}
return $result;
}
$desired_arr = group_by_key("id", $orginal_arr);
$desired_arr2 = array();
foreach ($desired_arr as $index => $item) {
$desired_arr2 += $item;
}
echo "<pre>";
print_r($desired_arr2);
echo "</pre>";
the output:
Array
(
[0] => Array
(
[id] => 17
[content] => string...?
)
[4] => Array
(
[id] => 17
[content] => string...
)
[5] => Array
(
[id] => 17
[content] => string...
)
[1] => Array
(
[id] => 20
[content] => hello
)
[2] => Array
(
[id] => 20
[content] => string...?
)
[3] => Array
(
[id] => 20
[content] => string...string...??
)
)
- Thank you very much.
As I said in my comment, I'm not familiar to PHP syntax anymore so this will be pseudo code.
I would do it in 2 steps,
first I want this result
$temp_arr =
Array
(
[0] => Array
(
[id] => 17
[contents] => Array(
[0] => string...?
)
)
[1] => Array
(
[id] => 20
[contents] => Array(
[0] => hello
[1] => string...?
[2] => string...string...??
)
)
...
...
);
See, I kept the Object structure with id and contents (with a final S).
then it will be easier to check the id as it is directly accessible
$temp_array = Array();
foreach ($original_array as $element) {
$last = end($temp_array);
if ($last && $element->id == $last->id) {
// add to the last $temp_array element
$temp_array[count($temp_array)-1]->contents[] = $element->content;
}
else {
// create a new $temp_array element
$temp_array[] = Array(
"id" => $element->id,
"contents => Array(
$element->content
)
);
}
}
For the second step you just need to iterate the $temp_array and format as you like
here is another solution to this problem.
$desired_arr = array();
$prev_id = '';
$prev_key = null;
foreach ($orginal_arr as $key => $value) {
$this_id = $value['id'];
if ($this_id == $prev_id) {
array_push($desired_arr[$prev_key][$value['id']], $value['content']);
} else {
$desired_arr[$key][$value['id']] = (array)$value['content'];
$prev_key = $key;
}
$prev_id = $this_id;
}
$desired_arr = array_values($desired_arr);

Extract specific values from stdClass Object

I have the following stdClass Object contained within $response:
stdClass Object ( [domain] => stdClass Object ( [id] => d1111111 [spamscore] => 75 [rejectscore] => 200 ) [domainalias] => Array ( ) [wildcard] => Array ( ) [catchall] => Array ( ) [forward] => Array ( ) [mailbox] => Array (
[0] => stdClass Object ( [highEmailNotification] => [id] => m1111111 [lastPasswordChange] => 2020-02-19T22:41:12+00:00 [local] => mailbox1 [lowEmailNotification] => [quotaMB] => 10240 [receive] => 1 [rejectscore] => [send] => 1 [spamscore] => [usageMB] => 0 [enabled] => 1 )
[1] => stdClass Object ( [highEmailNotification] => [id] => m2222222 [lastPasswordChange] => 2020-02-17T15:46:21+00:00 [local] => mailbox2 [lowEmailNotification] => [quotaMB] => 10240 [receive] => 1 [rejectscore] => [send] => 1 [spamscore] => [usageMB] => 0 [enabled] => 1 )
[2] => stdClass Object ( [highEmailNotification] => [id] => m3333333 [lastPasswordChange] => 2020-02-19T15:00:36+00:00 [local] => mailbox3 [lowEmailNotification] => [quotaMB] => 1024 [receive] => 1 [rejectscore] => 0 [send] => 1 [spamscore] => 75 [usageMB] => 0 [enabled] => 1 ) ) [spamblacklist] => Array ( ) [spamwhitelist] => Array ( ) [responder] => Array ( ) [name] => domain.com )
I need to convert it into an array and extract particular values, i.e. [id] and [local] from it.
Speed is also an issue, as this array will grow to thousands of items, so if there is other, quicker way than 'foreach' it would be better.
I used some suggestions from here, such as:
$array = json_decode(json_encode($response), True);
foreach ($array as $var)
{
echo $var['id'] . ' - ' . $var['local'] . "<br>";
}
and got partial success with the results:
d1111111 -
-
-
-
-
i - i
(so it found the very first [id] value)
it however missed the most important values I am after.
What I need to get is:
m1111111 - mailbox1
m2222222 - mailbox2
m3333333 - mailbox3
Any suggestions are greatly appreciated.
The values you're trying to print is in a nested array within $response.
Try this.
$array = json_decode(json_encode($response['mailbox']), True);
foreach ($array as $var)
{
echo $var['id'] . ' - ' . $var['local'] . "<br>";
}

Reindex PHP Nested Array

After printing my $my_values['outer_group']['fieldset'] I'm getting the following output as per the data:
Array
(
[fieldset] => Array
(
[1] => Array
(
[title] => Dummy_Value1
[inner_group] => Array
(
[fieldset] => Array
(
[1] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[2] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[3] => Array
(
[id] => 13
[title] => Dummy_Value13
)
[actions] => Array
(
[add] => Add InnerGroup
[remove] => Remove InnerGroup
)
)
)
)
[2] => Array
(
[title] => Dummy_Value2
[inner_group] => Array
(
[fieldset] => Array
(
[1] => Array
(
[id] => 21
[title] => Dummy_Value21
)
[actions] => Array
(
[add] => Add InnerGroup
)
)
)
)
[actions] => Array
(
[add] => Add OuterGroup
[remove] => Remove OuterGroup
)
)
)
My requirement is to re-index the output data, hence I've performed the following code to re-index the same:
<?php
if (isset($my_values['outer_group']) && !empty($my_values['outer_group'])) {
$outer_types = $my_values['outer_group']['fieldset'];
$inner = [];
foreach ($outer_types as $outer_key => $outer_value) {
if (is_numeric($outer_key)) {
if (isset($outer_value['inner_group']['fieldset'])) {
foreach ($outer_value['inner_group']['fieldset'] as $k => $v) {
if (is_numeric($k)) {
$inner[] = [
'id' => $v['id'],
'title' => !empty($v['title']) ? $token->replace($v['title']) : NULL,
];
}
}
}
$my_values['outer'][$outer_key] = [
'title' => !empty($outer_value['title']) ? $token->replace($outer_value['title']) : NULL,
'inner' => $inner,
];
}
}
}
As per the output its getting re-indexed but with some errors in data. I'm getting trouble while populating the [inner] data, following is the output for the same:
Array
(
[0] => Array
(
[title] => Dummy_Value1
[inner] => Array
(
[0] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[1] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[2] => Array
(
[id] => 13
[title] => Dummy_Value13
)
)
)
[1] => Array
(
[title] => Dummy_Value2
[inner] => Array
(
[0] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[1] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[2] => Array
(
[id] => 13
[title] => Dummy_Value13
)
[3] => Array
(
[id] => 21
[title] => Dummy_Value21
)
)
)
)
Whereas, it should be:
Array
(
[0] => Array
(
[title] => Dummy_Value1
[inner] => Array
(
[0] => Array
(
[id] => 11
[title] => Dummy_Value11
)
[1] => Array
(
[id] => 12
[title] => Dummy_Value12
)
[2] => Array
(
[id] => 13
[title] => Dummy_Value13
)
)
)
[1] => Array
(
[title] => Dummy_Value2
[inner] => Array
(
[0] => Array
(
[id] => 21
[title] => Dummy_Value21
)
)
)
)
$inner = []; needs to be within the foreach loop so that it is empty before building each internal element.
Untested - but as follows:
<?php
if (isset($my_values['outer_group']) && !empty($my_values['outer_group'])) {
$outer_types = $my_values['outer_group']['fieldset'];
foreach ($outer_types as $outer_key => $outer_value) {
$inner = [];
if (is_numeric($outer_key)) {
if (isset($outer_value['inner_group']['fieldset'])) {
foreach ($outer_value['inner_group']['fieldset'] as $k => $v) {
if (is_numeric($k)) {
$inner[] = [
'id' => $v['id'],
'title' => !empty($v['title']) ? $token->replace($v['title']) : NULL,
];
}
}
}
$my_values['outer'][$outer_key] = [
'title' => !empty($outer_value['title']) ? $token->replace($outer_value['title']) : NULL,
'inner' => $inner,
];
}
}
}

How to add new array in to existing array dynamically using session in codeigniter

i want to store multiple array in same session on every function call .. my function is given below.
function store_item($param='')
{
$count = count($this->session->userdata('items_array'));
echo $count;
$count++;
$item_id = $this->input->post('product_id');
$data[][$count] = $this->Quotation_model->get_data_single($item_id);
$this->session->set_userdata('items_array',$data);
}
i want this result
Array ( [0] => Array ( [0] => Array ( [name] => Check [category_id] => 1 [supplier_id] => ) ) Array ( [1] => Array ( [name] => Check [category_id] => 1 [supplier_id] => ) ) Array ( [2] => Array ( [name] => Check [category_id] => 1 [supplier_id] => ) ))
Try this you are overwriting session array each time
$data = $this->session->userdata('items_array');
echo $count;
$count++;
$item_id = $this->input->post('product_id');
$data[] = $this->Quotation_model->get_data_single($item_id);
$this->session->set_userdata('items_array',$data);
Here you are first get session details to variable then add new item details to same variable to set session again with new data

How do I format the output array in CakePHP

Let's say I have an index action where I want to get a list of projects:
$this->Project->find('all', array('order' => 'Project.modified DESC', 'conditions' => array('Project.user_id' => 1)));
It works well and returns the following array:
Array ( [0] => Array ( [Project] => Array ( [id] => 2 [title] => test project ) ) [1] => Array ( [Project] => Array ( [id] => 1 [title] => first project ) ) )
How do I modify the find function, so it returns the array in the following format:
Array ( [projects] => Array ( [0] => Array ( [id] => 2 [title] => test project ) [1] => Array ( [id] => 1 [title] => first project ) ) )
Thank you!
You could use the Set::combine() utility method to do this. I've used it for similar means as so:
public function groupByMenu() {
return Set::combine (
$this->find (
'all',
array (
'conditions' => array ( 'NavItem.active' => 1 ),
'order' => 'NavMenuItem.display_order'
)
),
'{n}.NavItem.title',
'{n}',
'{n}.NavMenu.id'
);
}
The code above takes a set of navigation items and reorganizes them so that they're grouped by the menu(s) they are displayed within.
It's not really clear if it's the fact that the result is under 'Project' rather than 'projects', but if you don't like that it's under [0] I believe you could use PHPs array_shift:
$result = $this->Project->find('all', array('order' => 'Project.modified DESC', 'conditions' => array('Project.user_id' => 1)));
$result = array_shift($result);
The result will be:
Array ( [Project] => Array ( [id] => 2 [title] => test project ) ) [1] => Array ( [Project] => Array ( [id] => 1 [title] => first project ) )
