How can we find the count of duplicate elements in a multidimensional array and concat of ids ?
I have an array of skill names with feed ids. I need to count skill name and concat of feed ids.
Array
(
[0] => Array
(
[skill_name] => PHP
[feed_id] => 100
)
[1] => Array
(
[skill_name] => CSS
[feed_id] => 105
)
[2] => Array
(
[skill_name] => Php
[feed_id] => 110
)
[3] => Array
(
[skill_name] => Php
[feed_id] => 111
)
[4] => Array
(
[skill_name] => CSS
[feed_id] => 112
)
[5] => Array
(
[skill_name] => Javascript
[feed_id] =>114
)
}
Output should be like below.
Array
(
[0] => Array
(
[skill_name] => PHP
[feed_id] => 100, 110, 111
[count]=>3
)
[1] => Array
(
[skill_name] => CSS
[feed_id] => 105, 112
[count]=>2
)
[2] => Array
(
[skill_name] => Javascript
[feed_id] => 114
[count]=>1
)
}
Thanks in advance!!
//Assumption: Input is in $in
//Step 1: Cumulate
$tmp=array();
foreach ($in as $skill) {
if (isset($tmp[$skill['skill_name']]))
$tmp[$skill['skill_name']][]=$skill['feed_id'];
else
$tmp[$skill['skill_name']]=array($skill['feed_id']);
}
//Step 2: Fix up desired output format
$out=array();
foreach ($tmp as $k=>$v)
$out[]=array(
'skill_name' => $k,
'feed_id' => implode(', ', $v),
'count' => sizeof($v)
);
//Result is in $out
This is perfectly achievable with a single loop using temporary keys and simple concatenation and incrementation.
Code: (Demo)
$array = [
['skill_name' => 'PHP', 'feed_id' => 100],
['skill_name' => 'CSS', 'feed_id' => 105],
['skill_name' => 'Php', 'feed_id' => 110],
['skill_name' => 'Php', 'feed_id' => 111],
['skill_name' => 'CSS', 'feed_id' => 112],
['skill_name' => 'Javascript', 'feed_id' => 114]
];
foreach ($array as $row) {
$upperSkill = strtoupper($row['skill_name']);
if (!isset($result[$upperSkill])) {
$result[$upperSkill] = $row + ['count' => 1]; // plus acts as array_merge here
} else {
$result[$upperSkill]['feed_id'] .= ",{$row['feed_id']}"; // concatenate
++$result[$upperSkill]['count']; // increment
}
}
var_export(array_values($result)); // reindex and display
Output:
array (
0 =>
array (
'skill_name' => 'PHP',
'feed_id' => '100,110,111',
'count' => 3,
),
1 =>
array (
'skill_name' => 'CSS',
'feed_id' => '105,112',
'count' => 2,
),
2 =>
array (
'skill_name' => 'Javascript',
'feed_id' => 114,
'count' => 1,
),
)

I need to convert the below 2d array in to specified 2d array format. Array contains multiple parent and multiple child array. Also, have tried to convert the code, but am not getting the expected output.
This is the code what i have tried,
$a1 = array(
'0' =>
array(
'banner_details' =>
array(
'id' => 2,
'section_id' => 24
),
'slide_details' =>
array(
0 => array(
'id' => 74,
'name' => 'Ads1'
),
1 => array(
'id' => 2,
'name' => 'Ads2'
)
)
),
'1' =>
array(
'banner_details' =>
array(
'id' => 106,
'section_id' => 92
),
'slide_details' =>
array(
0 => array(
'id' => 2001,
'name' => 'Adv1'
),
1 => array(
'id' => 2002,
'name' => 'Adv2'
)
)
)
);
$s = [];
for($i = 0; $i<2; $i++) {
foreach($a1[$i]['slide_details'] as $vs){
$s[] = $vs;
}
}
My output:
Array
(
[0] => Array
(
[id] => 74
[name] => Ads1
)
[1] => Array
(
[id] => 2
[name] => Ads2
)
[2] => Array
(
[id] => 2001
[name] => Adv1
)
[3] => Array
(
[id] => 2002
[name] => Adv2
)
)
Expected output:
Array
(
[24] => Array
(
[0] => 74
[1] => 2
)
[92] => Array
(
[0] => 2001
[1] => 2002
)
)
please check the above code and let me know.
Thanks,
You can apply next simple foreach loop with help of isset() function:
foreach($a1 as $data){
if (isset($data['banner_details']['section_id'])){
$s[$data['banner_details']['section_id']] = [];
if (isset($data['slide_details'])){
foreach($data['slide_details'] as $row){
$s[$data['banner_details']['section_id']][] = $row['id'];
}
}
}
}
Demo
If you know that indexes like banner_details or slide_details or section_id will be there always then you can skip isset() in if statements.
You can use array_column function for simple solution:
$result = [];
foreach ($a1 as $item)
{
$result[$item['banner_details']['section_id']] = array_column($item['slide_details'], 'id');
}
var_dump($result);
how to convert associative array to different array?
This is my array
$array=Array (
services => Array ( [0] => 6, [1] => 1, [2] => 3 ),
subservices => Array ( [0] => 'No data',[1] => 2 ,[2] => 'No data' ),
price=> Array ( [0] => 124, [1] => 789, [2] => 895 ),
);
and i want convert to
Array (
[0] => Array ( [services] => 6, [subservices] => 'No data', [price] => 124 )
[1] => Array ( [services] => 1, [subservices] => 2, [price] => 789 )
[2] => Array ( [services] => 3, [subservices] => 'No data', [price] => 895 )
)
How to do?
$outArray=array();
for($i=0;$i<count($sourceArray['services']);$i++)
{
$outArray[]=array('services'=>$sourceArray['services'][$i],'subservices'=>$sourceArray['subservices'][$i],'price'=>$sourceArray['price'][$i]);
}
Here is a dynamic approach. This will also allow for additional values in your sub arrays.
Hope it helps:
$array = array (
'services' => Array ( '0' => 6, '1' => 1, '2' => 3),
'subservices' => Array ( '0' => 'No data', '1' => 2, '2' => 'No data'),
'price' => Array ( '0' => 124, '1' => 789, '2' => 895)
);
//Get array keys.
$keys = array_keys($array);
//Iterate through the array.
for($i = 0; $i < count($array); $i++){
//Iterate through each subarray.
for($j = 0; $j < count($array[$keys[$i]]); $j++){
//Here we are checking to see if you have more data per element than your initial key count.
if($keys[$j]){
$index = $keys[$j];
} else {
$index = $j;
}
//Append results to the output array.
$results[$i][$index] = $array[$keys[$i]][$j];
}
}
echo '<pre>';
print_r($results);
echo '</pre>';
This will output:
Array
(
[0] => Array
(
[services] => 6
[subservices] => 1
[price] => 3
)
[1] => Array
(
[services] => No data
[subservices] => 2
[price] => No data
)
[2] => Array
(
[services] => 124
[subservices] => 789
[price] => 895
)
)
Php multidimensional array same key’s same value’s related total in
new array. I have an array of following mentioned. i need new array
as total qty of same item_id. anyone can help would be appreciate.
My Original Array is as following
Array
(
[a] => Array
(
[item] => Array
(
[item_id] => 1
)
[qty] => 0
),
[b] => Array
(
[item] => Array
(
[item_id] => 2
)
[qty] => 35
),
[c] => Array
(
[item] => Array
(
[item_id] => 2
)
[qty] => 15
),
[e] => Array
(
[item] => Array
(
[item_id] => 3
)
[qty] => 20
),
);
I want array Output like following :
Array(
[0] => Array (
[item_id] => 1,
[item_total_qty] => 0,
)
[1] => Array (
[item_id] => 2,
[item_total_qty] => 50,
)
[2] => Array (
[item_id] => 3,
[item_total_qty] => 20,
)
);
Hope it help
$arrays = array(
'a' => array(
'item' => array(
'item_id' => 1
),
'qty' => 0
),
'b' => array(
'item' => array(
'item_id' => 2
),
'qty' => 35
),
'c' => array(
'item' => array(
'item_id' => 2
),
'qty' => 15
),
'd' => array(
'item' => array(
'item_id' => 3
),
'qty' => 20
)
);
$result = array();
foreach ($arrays as $key => $array) {
if (is_array($result) && !empty($result)) {
foreach ($result as $key => $r) {
if ($r['item_id'] == $array['item']['item_id']) {
$result[$key]['item_total_qty'] += $array['qty'];
continue 2;
}
}
$result[] = array(
'item_id' => $array['item']['item_id'],
'item_total_qty' => $array['qty']);
} else {
$result[] = array(
'item_id' => $array['item']['item_id'],
'item_total_qty' => $array['qty']);
}
}
Simple foreach on your original table:
$sorted = array();
foreach ($original as $item) {
$id = $item['item']['item_id'];
$sorted[$id]['item_total_qty'] = $sorted[$id] ? $sorted[$id] + $item['qty'] : item['qty'];
$sorted[$id]['item_id'] = $id;
}
$sorted = array_values($sorted);
I have below array,
Array ( [0] => Array ( [location] => X33 [usernumber] => 1 [order] => XX [part_number] => Hi ) [1] => Array ( [location] => X33 [usernumber] => 1 [order] => XX [part_number] => 68730 ) [2] => Array ( [location] => W33 [usernumber] => 2 [order] => YY [part_number] => 68741) [3] => Array ( [location] => W33 [usernumber] => 2 [order] => YY [part_number] => Hello )
I want to filter this array with usernumber = 1, by this it will create 1 array with arrays which have usernumber = 1, similarly it will create for usernumber=2
I had users in DB and will search user in this array,
I tried below code,
$users = $this->admin_model->get_usersforshipment();
foreach ($users as $user) {
$filtered = array_filter($csv_array, function($user)
{ //Below is retrurning as orignal $csv_array, not filtered,
return !empty($user['usernumber']);
});
}
Desired output, when $users['usernumber] == 1
Array ( [0] => Array ( [location] => X33 [usernumber] => 1 [order] => XX [part_number] => Hi ) [1] => Array ( [location] => X33 [usernumber] => 1 [order] => XX [part_number] => 68730 ) )
Desired output, when $users['usernumber] == 2
Array ( [0] => Array ( [location] => W33 [usernumber] => 2 [order] => YY [part_number] => 68741) [1] => Array ( [location] => W33 [usernumber] => 2 [order] => YY [part_number] => Hello )
How can i filter only 2 arrays from Multi Dimension array?
Online Example, Description added after your feedback.
$arr = array(
array ('location' => 'X33',
'usernumber' => 1,
'order' => 'XX',
'part_number' => 'Hi'
),
array ('location' => 'X33',
'usernumber' => 1,
'order' => 'XX',
'part_number' => '68730'
),
array ('location' => 'W33',
'usernumber' => 2,
'order' => 'YY',
'part_number' => '68741'
),
array ('location' => 'W33',
'usernumber' => 2,
'order' => 'YY',
'part_number' => 'Hello'
)
);
$out = array();
$index = $arr[0]['usernumber'];
foreach($arr as $val){
if($index != $val['usernumber'])
$index = $val['usernumber'];
$out[$index][] = $val;
}
echo '<pre>';
print_r($out);
Currently, your array is defined like so:
$array = [
0 => [
'location' => l1
'usernumber' => 1
'order' => 'o1'
],
1 => [
'location' => l2
'usernumber' => 1
'order' => 'o2'
],
2 => [
'location' => l3
'usernumber' => 2
'order' => 'o3'
]
];
A good solution would be to set the usernumber variables as array keys. You could do this while creating the array, or you could alter it after creation. It should look like this:
$array = [
1 => [ // The key is now the usernumber
[
'location' => 'l1'
'order' => 'o1'
],
[
'location' => 'l2'
'order' => 'o2'
]
],
2 => [
[
'location' => 'l3'
'order' => 'o3'
],
]
];
Now you can simple grab the different orders by the usernumber and loop through them:
$orders = $array[1]; // Get all orders from the user with usernumber 1
foreach ($orders as $order) {
print_r($order);
}
I have 2 multidimensional arrays that I am working with:
$arr1 =
Array
([type] => characters
[version] => 5.6.7.8
[data] => Array
([Char1] => Array
([id] => 1
[name] =>Char1
[title] =>Example
[tags] => Array
([0] => DPS
[1] => Support))
[Char2] => Array
([id] => 2
[name] =>Char2
[title] =>Example
[tags] => Array
([0] => Tank
[1] => N/A)
)
)
etc...
$arr2=
Array
([games] => Array
([gameId] => 123
[gameType => Match
[char_id] => 1
[stats] => Array
([damage] => 55555
[kills] => 5)
)
([gameId] => 157
[gameType => Match
[char_id] => 2
[stats] => Array
([damage] => 12642
[kills] => 9)
)
etc...
Basically, I need almost all the data in $arr2... but only the Char name from $arr1. How could I merge or add the $arr1['name'] key=>value into $arr2 where $arr1['id'] is equal to $arr2['char_id'] as the "id" field of each array is the same number.
I've attempted using array_merge and array_replace, but I haven't come up with any working solutions. This is also all data that I am receiving from a 3rd party, so I have no control on initial array setup.
Thanks for any help or suggestions!
Actually, this is quite straighforward. (I don't think there a built-in function that does this.)
Loop $arr2 and under it loop also $arr1. While under loop, just add a condition that if both ID's match, add that particular name to $arr2. (And use some referencing & on $arr2)
Consider this example:
// your data
$arr1 = array(
'type' => 'characters',
'version' => '5.6.7.8',
'data' => array(
'Char1' => array(
'id' => 1,
'name' => 'Char1',
'title' => 'Example',
'tags' => array('DPS', 'Support'),
),
'Char2' => array(
'id' => 2,
'name' => 'Char2',
'title' => 'Example',
'tags' => array('Tank', 'N/A'),
),
),
);
$arr2 = array(
'games' => array(
array(
'gameId' => 123,
'gameType' => 'Match',
'char_id' => 1,
'stats' => array('damage' => 55555, 'kills' => 5),
),
array(
'gameId' => 157,
'gameType' => 'Match',
'char_id' => 2,
'stats' => array('damage' => 12642, 'kills' => 9),
),
),
);
foreach($arr2['games'] as &$value) {
$arr2_char_id = $value['char_id'];
// loop and check against the $arr1
foreach($arr1['data'] as $element) {
if($arr2_char_id == $element['id']) {
$value['name'] = $element['name'];
}
}
}
echo '<pre>';
print_r($arr2);
$arr2 should look now like this:
Array
(
[games] => Array
(
[0] => Array
(
[gameId] => 123
[gameType] => Match
[char_id] => 1
[stats] => Array
(
[damage] => 55555
[kills] => 5
)
[name] => Char1 // <-- name
)
[1] => Array
(
[gameId] => 157
[gameType] => Match
[char_id] => 2
[stats] => Array
(
[damage] => 12642
[kills] => 9
)
[name] => Char2 // <-- name
)
)
)
Iterate over $arr2 and add the data to it from the matching $arr1 array value:
$i = 0;
foreach($arr2['games'] as $arr2Game){
$id = $arr2Game['char_id'];
$arr2['games'][$i]['name'] = $arr1['data'][$id]['name'];
$i++;
}
Have not tested this code.
If I'm understanding you correctly, you want to add a name index to each of the arrays within the $arr2['games'] array.
foreach($arr2['games'] as $key => $innerArray)
{
$arr2['games'][$key]['name'] = $arr1['data']['Char'.$innerArray['char_id']]['name'];
}
