Php creating associative array from another array - php

I am using an array that I get from a database and I would like to create an associative array from that one.
Here is the code I am using:
print_r($data_sites);
// Format for easy use
$data_sites_formatted = array();
foreach ($data_sites as $key => $row) {
if (empty($data_formatted[$row->project_loe_id])) {
$data_sites_formatted[$row->project_loe_id] = array();
}
$data_sites_formatted[$row->project_loe_id][$row->name] = array();
$data_sites_formatted[$row->project_loe_id][$row->name]['id'] = $row->id;
$data_sites_formatted[$row->project_loe_id][$row->name]['quantity'] = $row->quantity;
$data_sites_formatted[$row->project_loe_id][$row->name]['loe_per_quantity'] = $row->loe_per_quantity;
}
print_r($data_sites_formatted);
Here is the information I receive from the database:
Illuminate\Support\CollectionObject ( [items:protected] => Array (
[0] => stdClass Object ( [id] => 1 [project_loe_id] => 1 [name] => site [quantity] => 20 [loe_per_quantity] => 1 )
[1] => stdClass Object ( [id] => 2 [project_loe_id] => 1 [name] => switches [quantity] => 5 [loe_per_quantity] => 3 )
[2] => stdClass Object ( [id] => 3 [project_loe_id] => 2 [name] => site [quantity] => 20 [loe_per_quantity] => 1 )
[3] => stdClass Object ( [id] => 4 [project_loe_id] => 2 [name] => ap [quantity] => 5 [loe_per_quantity] => 3 )
[4] => stdClass Object ( [id] => 5 [project_loe_id] => 2 [name] => wireless [quantity] => 5 [loe_per_quantity] => 3 ) ) )
And when I do the transformation, here is the result:
Array (
[1] => Array ( [switches] => Array ( [id] => 2 [quantity] => 5 [loe_per_quantity] => 3 ) )
[2] => Array ( [wireless] => Array ( [id] => 5 [quantity] => 5 [loe_per_quantity] => 3 ) ) )
I lost 3 lines and I really have no idea why. I can see when I look into details step by step that it deletes some lines from 1 iteration to the next:
Iteration:0
Array (
[1] => Array ( [site] => Array ( [id] => 1 [quantity] => 20 [loe_per_quantity] => 1 ) ) )
Iteration: 1
Array (
[1] => Array ( [switches] => Array ( [id] => 2 [quantity] => 5 [loe_per_quantity] => 3 ) ) )
Iteration: 2
Array (
[1] => Array ( [switches] => Array ( [id] => 2 [quantity] => 5 [loe_per_quantity] => 3 ) )
[2] => Array ( [site] => Array ( [id] => 3 [quantity] => 20 [loe_per_quantity] => 1 ) ) )
Iteration: 3
Array (
[1] => Array ( [switches] => Array ( [id] => 2 [quantity] => 5 [loe_per_quantity] => 3 ) )
[2] => Array ( [ap] => Array ( [id] => 4 [quantity] => 5 [loe_per_quantity] => 3 ) ) )
Iteration: 4
Array (
[1] => Array ( [switches] => Array ( [id] => 2 [quantity] => 5 [loe_per_quantity] => 3 ) )
[2] => Array ( [wireless] => Array ( [id] => 5 [quantity] => 5 [loe_per_quantity] => 3 ) ) )
You can see from iteration 0 to iteration 1, it deleted the line from iteration 0 and in iteration 1 I should have 2 lines.

You have a typo here:
if (empty($data_formatted[$row->project_loe_id])) {
$data_sites_formatted[$row->project_loe_id] = array();
}
$data_formatted is never defined (you meant to write $data_sites_formatted) so empty($data_formatted[$row->project_loe_id]) is always true, and always runs the next line, replacing anything previously added to $data_sites_formatted[$row->project_loe_id] with an empty array. So all you end up with is the last item to be added in each group.

Joining two multidimensional arrays

I have two arrays each coming from different DB queries, I can't join them in DB so I have to join them using php.
The first:
Array
(
[0] => Array
(
[id] => 23
[host_id] => 5
[pos_id] => 2
[status] => 1
)
[1] => Array
(
[id] => 25
[host_id] => 5
[pos_id] => 1
[status] => 1
)
[2] => Array
(
[id] => 24
[host_id] => 5
[pos_id] => 2
[status] => 1
)
)
And I wanna join it with this array on pos_id and id
Array
(
[0] => Array
(
[id] => 1
[name] => Front
)
[1] => Array
(
[id] => 2
[name] => Back
)
)
so that, the result is:
Array
(
[0] => Array
(
[id] => 23
[host_id] => 5
[pos_id] => 2
[name] => Back
[status] => 1
)
[1] => Array
(
[id] => 25
[host_id] => 5
[pos_id] => 1
[name] => Front
[status] => 1
)
[2] => Array
(
[id] => 24
[host_id] => 5
[pos_id] => 2
[name] => Back
[status] => 1
)
)
The code I have uses an inner loop, matches the value and pushes into array:
foreach($events as &$event) {
foreach($positions as $position) {
if($player[pos_id] == $position[id]){
array_push($event,"name",$position[name]);
}
}
}

Shift Recursive nested child array to parent array PHP

I have an issue with forming a recursive array. That is shifting the child array nodes to direct elements to a parent array.
like from,
Array
(
[0] => Array
(
[id] => 1
[category_name] => flare
[parent_category_id] => 0
[childrenrecursive] => Array
(
[0] => Array
(
[id] => 2
[category_name] => analytics
[parent_category_id] => 1
[braincount] => Array
(
[count] => 3
[category_id] => 2
)
[childrenrecursive] => Array
(
[0] => Array
(
[id] => 4
[category_name] => sports analytics
[parent_category_id] => 2
[braincount] => Array
(
[count] => 4
[category_id] => 4
)
[childrenrecursive] => Array
(
)
)
)
)
[1] => Array
(
[id] => 3
[category_name] => cluster
[parent_category_id] => 1
[braincount] => Array
(
[count] => 4
[category_id] => 3
)
[childrenrecursive] => Array
(
)
)
)
)
)
to,
Array
(
[0] => Array
(
[id] => 1
[category_name] => flare
[parent_category_id] => 0
[childrenrecursive] => Array
(
[0] => Array
(
[id] => 2
[category_name] => analytics
[parent_category_id] => 1
[count] => 3
[category_id] => 2
[childrenrecursive] => Array
(
[0] => Array
(
[id] => 4
[category_name] => sports analytics
[parent_category_id] => 2
[count] => 4
[category_id] => 4
[childrenrecursive] => Array
(
)
)
)
)
[1] => Array
(
[id] => 3
[category_name] => cluster
[parent_category_id] => 1
[count] => 4
[category_id] => 3
[childrenrecursive] => Array
(
)
)
)
)
)
only by moving following child array append to parent in a recursive way.
[braincount] => Array
(
[count] => 4
[category_id] => 3
)
can anybody help me to format the array like specified.
Let's say $input is the array posted in the question:
/**
* If $value is an array then move the content of 'braincount' one level up
* (in $value) then call recursively for all its children.
*/
function moveUp($value)
{
// Not an array? Nothing to do; return the input value unchanged
if (! is_array($value)) {
return $value;
}
// Move the content of 'braincount' (if present) one level up
if (array_key_exists('braincount', $value)) {
$value = array_merge($value, $value['braincount']);
unset($value['braincount']);
}
// Apply the same operation to all children
return array_map(__FUNCTION__, $value);
}
// Verify it works
print_r(moveUp($input));

Compare values of two multidimentional array and insert if not exits

I have two array $array1 and $array2 which I get dynamically and look like
$array1 = Array
(
[0] => Array
(
[hour] => 10
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 2
)
[1] => Array
(
[activity_id] => 2
[cnt] => 1
)
)
)
[1] => Array
(
[hour] => 11
[activity] => Array
(
)
)
[2] => Array
(
[hour] => 12
[percentage] => 0
[activity] => Array
(
[0] => Array
(
[activity_id] => 2
[cnt] => 5
)
[1] => Array
(
[activity_id] => 3
[cnt] => 2
)
)
)
);
$array2 = Array
(
[0] => Array
(
[id] => 1
[name] => Phone Calls
[readable] => 1
[status] => active
)
[1] => Array
(
[id] => 2
[name] => Meeting With Customer
[readable] => 1
[status] => active
)
[2] => Array
(
[id] => 3
[name] => Others Works
[readable] => 1
[status] => active
)
);
which i need to compare.
if $array2['id'] is not in $array1["activity"](i.e"activity_id") add array ['activity_id'=>$array2['id'],'cnt'=>0] to $array1['activity'].
My result must be like
$result = Array
(
[0] => Array
(
[hour] => 10
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 2
)
[1] => Array
(
[activity_id] => 2
[cnt] => 1
)
[2] => Array
(
[activity_id] => 3
[cnt] => 0
)
)
)
[1] => Array
(
[hour] => 11
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 0
)
[1] => Array
(
[activity_id] => 2
[cnt] => 0
)
[2] => Array
(
[activity_id] => 3
[cnt] => 0
)
)
)
[2] => Array
(
[hour] => 12
[percentage] => 0
[activity] => Array
(
[0] => Array
(
[activity_id] => 1
[cnt] => 0
)
[1] => Array
(
[activity_id] => 2
[cnt] => 5
)
[2] => Array
(
[activity_id] => 3
[cnt] => 2
)
)
)
);
What i have tried is
$finalArray = array();
foreach($array1 as $arr1) {
foreach($array2 as $arr2) {
if(!in_array($arr2['id'], $arr1['activity'])) {
$array = ['activity_id'=>$arr2['id'], 'cnt'=>0];
}
array_push($arr1['activity'], $array);
unset($array);
}
array_push($finalArray, $result);
}
print_r($finalArray);
in_array() function is not working as I excepted or I am trying to do it in the wrong way. Can someone helps me with this?
Sorry,finally i get what i did wrong.May be someone get helped.
everything is ok just change the line
if(!in_array($arr2['id'], $arr1['activity'])) {
into
if(!in_array( $readActivity['id'], array_column($result['activity'],'activity_id'))){

How to remove duplicate data in an array?

[0] => Array
(
[total_sell] => 6
)
)
[1] => Array
(
[Import] => Array
(
[product_id] => 2
[id] => 2
[category_id] => 2
[amount] => 15
[cost] => 3000
[paid] => 0
[comment] =>
[created] => 2015-06-22 12:10:36
)
[0] => Array
(
[total_sell] => 1
)
)
)
Would you write a function to filter this type of array and produce expected result. I have been googling for 2 days but no luck.
This is a handy one liner that should do the trick:
$unique= array_map("unserialize", array_unique(array_map("serialize", $original)));
If the underlying arrays are not identical, that won't work, in which case I think you could do:
$unique = array_intersect_key($original ,
array_unique(
array_map(function($item) {
return $item['Import']['product_id'];
}, $original)
)
);
Tested: http://sandbox.onlinephpfunctions.com/code/8aee5cbd614e0ddd1a03dfaa7e98c72fbbe7d68d
Here is a quick stable sort and reduce which runs in linearithmic time. First-encountered product Id's are kept, and entries with duplicate product Id's are ignored.
// Stable sort
sort($in);
// Reduce
$out = array_reduce($in, function(&$acc, &$item){
if($item['Import']['product_id'] !== #$acc[sizeof($acc)-1]['Import']['product_id']) {
$acc[] = $item;
}
return $acc;
}, []);
Demo: http://ideone.com/BP0eUJ
Update: Here is an even better linear-time algorithm that does the same as above using a fast "hash table" lookup. Again, the first-encountered product Id is kept and subsequent ones of the same Id are ignored.
$out = [];
$hashTable = [];
foreach($in as $item) {
$pid = $item['Import']['product_id'];
if(!isset($hashTable[$pid])) {
$out[] = $item;
$hashTable[$pid] = true;
}
}

recursive function to transform multidimentional array

I have an array after an SQL query made with cake PHP which returns me a tree. I do not the number of dimension of my array.
I want transform it to use it with jstree. I'm fighting with a recursive function and I didn't success.
Can you help me.
My original array looks like this:
Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 815
[Name] => 1
[parent_id] =>
[lft] => 1
[rght] => 30
)
[children] => Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 816
[Name] => 2
[parent_id] => 815
[lft] => 2
[rght] => 15
)
[children] => Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 817
[parent_id] => 816
[lft] => 3
[rght] => 8
)
[children] => Array
(
[0] => Array
(
[Confsave] => Array
(
[id] => 818
[Name] => 4
[parent_id] => 817
[lft] => 4
[rght] => 5
)
[children] => Array
(
)
)
[1] => Array
(
[Confsave] => Array
(
[id] => 819
[Name] => 5
[parent_id] => 817
[lft] => 6
[rght] => 7
)
[children] => Array
(
)
)
)
)
)
)
)
)
)
And I want have something like this :
Array
(
[0] => Array
(
[text] => 1
[id] => 815
[children] => Array
(
[0] => Array
(
[text] => 2
[id] => 816
[children] => Array
(
[0] => Array
(
[text] => 3
[id] => 817
[children] => Array
(
[0] => Array
(
[text] => 4
[id] => 818
)
)
)
[1] => Array
(
[text] => 5
[id] => 819
)
)
)
)
)
)
I have try with a recursive function like this but I don't success
private function buildTree(array $elements) {
$branch=array();
foreach ($elements as $element){
$branch[]=$element['Confsave']['Name'];
if(is_array($element['children'])){
$this->buildTree($element);
}
}
return $branch;
}
Edit :
After test and remarks my function is now
private function buildTree(array $elements) {
$branch=array();
foreach ($elements as $element){
$branch[]=$element['Confsave']['Name'];
if(is_array($element['children'])){
$this->buildTree($element['children']);
}
}
return $branch;
}
When I am debuging, I can see that I go to my function for each child (what I want). But I don't know how to make the new array()
this worked for me...
$array = buildTree($array);
print_r($array);
function buildTree(array $parent) {
$branch = array();
foreach ($parent as $index => $element){
$node = array();
$node['id'] = $element['Confsave']['id'];
$node['text'] = isset($element['Confsave']['Name']) ?
$element['Confsave']['Name'] : 'no name';
$node['children'] = buildTree($element['children']);
$branch[] = $node;
}
return $branch;
}
