Merge 1 multidimensional array with a simple array - php

I am trying to merge 2 arrays: 1 multidimensional and another one normal:
Multidimensional array - $_SESSION["products"]
array (size=2)
0 =>
array (size=4)
'name' => string 'Lg Monitor' (length=10)
'code' => string '30' (length=2)
'qty' => string '1' (length=1)
'price' => string '1300.50' (length=7)
1 =>
array (size=4)
'name' => string 'Smasung Monitor' (length=15)
'code' => string '29' (length=2)
'qty' => string '1' (length=1)
'price' => string '2300.50' (length=7)
Simple array - $qty
array (size=2)
0 => string '2' (length=1)
1 => string '3' (length=1)
EXPECTED OUTPUT
array (size=2)
0 =>
array (size=4)
'name' => string 'Lg Monitor' (length=10)
'code' => string '30' (length=2)
'qty' => string '2' (length=1) // notice the qty change
'price' => string '1300.50' (length=7)
1 =>
array (size=4)
'name' => string 'Smasung Monitor' (length=15)
'code' => string '29' (length=2)
'qty' => string '3' (length=1) // notice the qty change
'price' => string '2300.50' (length=7)
I tried:
foreach ($_SESSION["products"] as $cart_itm){
foreach($qty as $qt) {
$cart_itm['qty'] = $qt;
}
}
But did not work, cart_itm['qty'] remained the same (1).


Try with this:
foreach ($_SESSION["products"] as $key => &$cart_itm){
$cart_itm['qty'] = $qty[$key];
}

Remove array 0 in array PHP

I have 2 product id and my code is:
$Final=array();
foreach ($ids as $me)
{
$op=DB::table('product')->where(['id'=>$me])->get();
//$Final[]= $op;
array_push($Final,$op);
}
This code returns:
array (size=1)
0 =>
array (size=1)
0 =>
array (size=15)
'id' => string '34' (length=2)
'title' => string 'گوسفند' (length=12)
'title_url' => string 'sheep' (length=5)
'code' => string 'eerer' (length=5)
'code_url' => string 'eerer' (length=5)
'content' => string '<p>sheep</p>
' (length=14)
'cat' => string '68' (length=2)
'price' => string '50000' (length=5)
'product_state' => string '1' (length=1)
'date' => string '' (length=0)
'order_number' => string '0' (length=1)
'Special' => string '0' (length=1)
'View' => string '0' (length=1)
'number_product' => string '1' (length=1)
'discounts' => string '' (length=0)
I need to remove
array (size=2) 0 => array (size=1) 0 =>
$ids => filter id
for get product number for example (22,34)

I Think you should try this.
$Final=array();
foreach ($ids as $me){
$op=DB::table('product')->where(['id'=>$me])->get();
if($op) {
array_push($Final,$op[0]);
}
}
Then you will get these values.
array (size=2)
0 =>
array (size=15)
'id' => string '34' (length=2)
1 =>
array (size=15)
'id' => string '22' (length=2)

If you are using Any framework then framwork provide us some methods to run query with where in to get all the records in single query.
$op=DB::table('product')->whereIn('id'=>$ids)->get();
you will get array of collection for all the products.

fill missing dates for specific key and value

I have an array:
array (size=3)
0 =>
array (size=3)
'quantity' => string '20' (length=2)
'date' => string '2016-01-01' (length=10)
'eID' => string '2' (length=1)
1 =>
array (size=3)
'quantity' => string '10' (length=2)
'date' => string '2016-03-01' (length=10)
'eID' => string '2' (length=1)
2 =>
array (size=3)
'quantity' => string '15' (length=2)
'date' => string '2016-01-01' (length=10)
'eID' => string '1' (length=1)
how can i fill missing date for each 'eID'? so the output would be:
array (
0 =>
array (
'quantity' => string '20' (length=2)
'date' => string '2016-01-01' (length=10)
'eID' => string '2' (length=1)
1 =>
array (
'quantity' => null
'date' => string '2016-02-01' (length=10)
'eID' => string '2' (length=1)
2 =>
array (
'quantity' => string '10' (length=2)
'date' => string '2016-03-01' (length=10)
'eID' => string '2' (length=1)
...until 2016-12-01. 12 arrays for each 'eID' key with same value

Sort multidimensional arrays recursively after setting up child-parent realtions

I have a database structure like this:
ID name sort parent
1 item1 1 0
2 subitem1 2 1
3 subsubitem1 1 2
4 subitem2 1 1
I write the database into an array
array (size=4)
0 =>
array (size=4)
'id' => string '1' (length=1)
'name' => string 'item1' (length=5)
'parent' => string '0' (length=1)
'sort' => string '1' (length=1)
1 =>
array (size=4)
'id' => string '2' (length=1)
'name' => string 'subitem1' (length=8)
'parent' => string '1' (length=1)
'sort' => string '2' (length=1)
2 =>
array (size=4)
'id' => string '3' (length=1)
'name' => string 'subsubitem1' (length=11)
'parent' => string '2' (length=1)
'sort' => string '1' (length=1)
3 =>
array (size=4)
'id' => string '4' (length=1)
'name' => string 'subitem2' (length=8)
'parent' => string '1' (length=1)
'sort' => string '1' (length=1)
and restructure that array to set up child-parent relations with this function:
function generateNavArray($arr, $parent = 0)
{
$items = Array();
foreach($arr as $item)
{
if($item['parent'] == $parent)
{
$item['child'] = isset($item['child']) ? $item['child'] : GenerateNavArray($arr, $item['id']);
$items[] = $item;
}
}
return $items;
}
and the generated array looks like this
array (size=1)
0 =>
array (size=5)
'id' => string '1' (length=1)
'name' => string 'item1' (length=5)
'parent' => string '0' (length=1)
'sort' => string '1' (length=1)
'child' =>
array (size=2)
0 =>
array (size=5)
'id' => string '2' (length=1)
'name' => string 'subitem' (length=4)
'parent' => string '1' (length=1)
'sort' => string '2' (length=1)
'child' =>
array (size=1)
0 =>
array (size=5)
'id' => string '3' (length=1)
'name' => string 'subsubitem1' (length=11)
'parent' => string '2' (length=1)
'sort' => string '1' (length=1)
'child' =>
array (size=0)
empty
1 =>
array (size=5)
'id' => string '3' (length=1)
'name' => string 'subitem2' (length=8)
'parent' => string '1' (length=1)
'sort' => string '1' (length=1)
'child' =>
array (size=0)
empty
now i need to sort every dimension of the array by the sort value, (my "real array" has more subarrays then this one).
i played around with multisort but i can't seem to find the solution
any ideas?

Sort the array when it is 1 dimension before you build the multi-dimensional array. Even better if you are using a query, sort it there. Sort by parent then sort. When you build your multidimensional array, each child will be appended to the parent. If they are already in the correct order, they will end up in the same order.

What I'm trying
foreach($extra_fields_array['attr'] as $key=>$value)

$new_array['attr'][$key] = array_merge($nvalue,$ovalue); // NOT WORKING
/*
* What do I do here
*/
}
echo '<pre>'; var_dump($new_array);echo '</pre>';
I hope this makes sense. I've been stuck on it all day.
Thanks for any help in advance.

how to decode a json string and add to array in PHP

I have a few records from database and I fetched all records. The array return as the code below
array (size=10)
0 =>
array (size=5)
'id' => string '1' (length=1)
'type' => string 'group' (length=5)
'members' => null
'parents' => string '0' (length=1)
'level' => string '1' (length=1)
1 =>
array (size=5)
'id' => string '2' (length=1)
'type' => string 'group' (length=5)
'members' => null
'parents' => string '0' (length=1)
'level' => string '1' (length=1)
2 =>
array (size=5)
'id' => string '3' (length=1)
'type' => string 'team' (length=4)
'members' => string '["3","5","6"]' (length=13)
'parents' => string '1' (length=1)
'level' => string '2' (length=1)
3 =>
array (size=5)
'id' => string '4' (length=1)
'type' => string 'team' (length=4)
'members' => string '["1"]' (length=5)
'parents' => string '1' (length=1)
'level' => string '2' (length=1)
4 =>
array (size=5)
'id' => string '5' (length=1)
'type' => string 'group' (length=5)
'members' => null
'parents' => string '1' (length=1)
'level' => string '2' (length=1)
5 =>
array (size=5)
'id' => string '8' (length=1)
'type' => string 'team' (length=4)
'members' => string '["4"]' (length=5)
'parents' => string '5' (length=1)
'level' => string '3' (length=1)
6 =>
array (size=5)
'id' => string '9' (length=1)
'type' => string 'team' (length=4)
'members' => string '["2"]' (length=5)
'parents' => string '5' (length=1)
'level' => string '3' (length=1)
7 =>
array (size=5)
'id' => string '10' (length=2)
'type' => string 'team' (length=4)
'members' => null
'parents' => string '5' (length=1)
'level' => string '3' (length=1)
8 =>
array (size=5)
'id' => string '11' (length=2)
'type' => string 'team' (length=4)
'members' => null
'parents' => string '5' (length=1)
'level' => string '3' (length=1)
9 =>
array (size=5)
'id' => string '12' (length=2)
'type' => string 'group' (length=5)
'members' => null
'parents' => string '1' (length=1)
'level' => string '2' (length=1)
the members field has been encoded as json string. I want to build a array with format as the code below
array('1'=>array(1,2,3,4,5,6),
'2'=>array(),
'3'=>array(3,5,6),
'4'=>array(1),
'5'=>array(2,4),
'8'=>array(4),
'9'=>array(2))
The record's id will be key of array and the members has decoded will become the value. I wrote a function handle the array return from the database but the result not as my intention. This is my code
$results = mysql_query('select id,type,members,parents,level from team');
$array = array();
recursiveDate($results,0,$array);
function recursiveData($sourceArr,$parents = 0, &$newMenu){
if(count($sourceArr)>0){
foreach ($sourceArr as $key => $value){
if($value['parents'] == $parents){
if(isset($newMenu[$value['id']])){
$newMenu[$value['id']] = array();
}
$newMenu[$value['id']] = $value['members']?json_decode($value['members']):array();
if(isset($newMenu[$parents])){
$newMenu[$parents] = array_merge($newMenu[$value['id']],$newMenu[$parents]);
}
$newParents = $value['id'];
unset($sourceArr[$key]);
$this->recursiveData($sourceArr,$newParents, $newMenu);
}
}
}
}
And this is the array after handled
array (size=10)
1 =>
array (size=4)
0 => string '1' (length=1)
1 => string '3' (length=1)
2 => string '5' (length=1)
3 => string '6' (length=1)
3 =>
array (size=3)
0 => string '3' (length=1)
1 => string '5' (length=1)
2 => string '6' (length=1)
4 =>
array (size=1)
0 => string '1' (length=1)
5 =>
array (size=2)
0 => string '2' (length=1)
1 => string '4' (length=1)
8 =>
array (size=1)
0 => string '4' (length=1)
9 =>
array (size=1)
0 => string '2' (length=1)
10 =>
array (size=0)
empty
11 =>
array (size=0)
empty
12 =>
array (size=0)
empty
2 =>
array (size=0)
empty
Please help me build that array

I quickly wrote this so not sure if it's exactly what you're looking for, looks like you over complicated it hugely though. I kept the original result structure incase you wanted that but you can easily overwrite it if you wish.
function modifyData($data = array()) {
foreach($data as &$entry) {
if(!empty($entry['members'])) {
$entry['members'] = json_decode($entry['members'], true);
} else {
$entry['members'] = array();
}
}
return $data;
}
I tested this with
$data = array(
array(
'id' =>'1',
'type' =>'group',
'members' => null,
'parents' =>'0',
'level' =>'1'
),
array(
'id' =>'1',
'type' =>'group',
'members' => '["3","5","6"]',
'parents' =>'0',
'level' =>'1'
),
array(
'id' =>'1',
'type' =>'group',
'members' => '["3"]',
'parents' =>'0',
'level' =>'1'
)
);
And the output is
array (size=3)
0 =>
array (size=5)
'id' => string '1' (length=1)
'type' => string 'group' (length=5)
'members' =>
array (size=0)
empty
'parents' => string '0' (length=1)
'level' => string '1' (length=1)
1 =>
array (size=5)
'id' => string '1' (length=1)
'type' => string 'group' (length=5)
'members' =>
array (size=3)
0 => string '3' (length=1)
1 => string '5' (length=1)
2 => string '6' (length=1)
'parents' => string '0' (length=1)
'level' => string '1' (length=1)
2 =>
array (size=5)
'id' => string '1' (length=1)
'type' => string 'group' (length=5)
'members' =>
array (size=1)
0 => string '3' (length=1)
'parents' => string '0' (length=1)
'level' => string '1' (length=1)
