I'm trying to merge two arrays. One array has names, and other has values. I want to merge them in a single multidimensional array in a way that values are in same sub-array if their names are similar. I'm new to programming and haven't been able to do anything
Names:
Array
(
[0] => TestAgent
[1] => TestAgent1
[2] => TestAgent1
[3] => TestAgent2
[4] => TestAgent2
[5] => TestAgent2
)
Values:
Array
(
[0] => 2019-04
[1] => 2019-05
[2] => 2019-06
[3] => 2019-04
[4] => 2019-05
[5] => 2019-06
)
This is desired output
Array
(
[0] => Array
(
[0] => TestAgent
[1] => 2019-04
)
[1] => Array
(
[0] => TestAgent1
[1] => 2019-05
[2] => 2019-06
)
[2] => Array
(
[0] => TestAgent2
[1] => 2019-04
[2] => 2019-05
[3] => 2019-06
)
)
Get the different counts of values from array_count_values() on the $names array, then use that to define the number of elements to use in array_slice(). The number of sliced elements adds to the count of the next offset.
$counts = array_count_values($names);
$offset = 0;
foreach (array_values(array_unique($names)) as $key=>$name) {
$slice = array_slice($values, $offset, $counts[$name]);
$offset += count($slice);
$result[$name] = $slice;
}
print_r($result);

You can use array_intersect_key to get the matching values from the names array.
This method does not need sorted array(s).
$names = ['TestAgent1', 'TestAgent', 'TestAgent1', 'TestAgent1', 'TestAgent2', 'TestAgent2', 'TestAgent2'];
$values = ['2019-01', '2019-04', '2019-05', '2019-06', '2019-04', '2019-05', '2019-06'];
$unique = array_unique($names);
foreach($unique as $name){
$res[] = array_merge([$name], array_intersect_key($values, array_intersect($names, [$name])));
}
print_r($res);
Output:
Array
(
[0] => Array
(
[0] => TestAgent1
[1] => 2019-01
[2] => 2019-05
[3] => 2019-06
)
[1] => Array
(
[0] => TestAgent
[1] => 2019-04
)
[2] => Array
(
[0] => TestAgent2
[1] => 2019-04
[2] => 2019-05
[3] => 2019-06
)
)

<?php
$one =
[
'Testagent',
'Testagent1',
'Testagent1',
'Testagent2',
'Testagent2',
'Testagent2'
];
$two =
[
'2019-04',
'2019-05',
'2019-06',
'2019-04',
'2019-05',
'2019-06'
];
$n = -1;
$previous = null;
foreach($one as $k=>$v) {
if($v !== $previous)
$items[++$n][] = $v;
$items[$n][] = $two[$k];
$previous = $v;
}
var_export($items);
Output:
array (
0 =>
array (
0 => 'Testagent',
1 => '2019-04',
),
1 =>
array (
0 => 'Testagent1',
1 => '2019-05',
2 => '2019-06',
),
2 =>
array (
0 => 'Testagent2',
1 => '2019-04',
2 => '2019-05',
3 => '2019-06',
),
)
If the first array does not have grouped like values do an asort on them first.

I have 2 Array:
$arr1 = Array (
[2] => Array ( [0] => 41000 [1] => 31079 )
[3] => Array ( [0] => 42963 [1] => 41189 )
)
$arr2 = Array (
[2] => Array ( [0] => 40213 [1] => 42054 )
[3] => Array ( [0] => 42998 [1] => 34567 )
)
I want to combine these two arrays to this array with same key:
$arr3 = Array (
[2] => Array ( [0] => 40213 [1] => 42054 [2] => 41000 [3] => 31079 )
[3] => Array ( [0] => 42998 [1] => 34567 [2] => 42963 [3] => 41189 )
)
I tried almost anything (merge, combine, join) but I can't figure it out. Any suggestions?
This is a nice and easy thing to do.
$arr1 = [2 => [0 => 41000, 1 => 31079], 3 => [0 => 42963, 1 => 41189]];
$arr2 = [2 => [0 => 40213, 1 => 42054], 3 => [0 => 42998, 1 => 34567]];
function addArray(&$bucket, $water)
{
foreach ($water as $key => $drop) {
$bucket[$key] = array_merge($bucket[$key] ?? [], $drop);
}
}
$combined = [];
addArray($combined, $arr1);
addArray($combined, $arr2);
var_export($combined);
See a PHP fiddle here.
The output is:
array (
2 =>
array (
0 => 41000,
1 => 31079,
2 => 40213,
3 => 42054,
),
3 =>
array (
0 => 42963,
1 => 41189,
2 => 42998,
3 => 34567,
),
)
How does it work? I wrote a little function that would add the input arrays to an array that combines all arrays.
$arr1 = array(
2 => array(41000, 31079),
3 => array(42963, 41189)
);
$arr2 = array(
2 => array(40213, 42054),
3 => array(42998, 34567)
);
$arr3 = array();
foreach($arr1 as $key => $values){
if(!isset($arr3[$key])){
$arr3[$key] = array();
}
$arr3[$key] = array_merge($arr3[$key], $values);
}
foreach($arr2 as $key => $values){
if(!isset($arr3[$key])){
$arr3[$key] = array();
}
$arr3[$key] = array_merge($arr3[$key], $values);
}
echo '<pre>';
print_r($arr3);
Prints:
Array
(
[2] => Array
(
[0] => 41000
[1] => 31079
[2] => 40213
[3] => 42054
)
[3] => Array

[0] => 42963

I have two associative arrays like
Array
(
[0] => Array
(
[0] => 2022-01-19
[1] => 6
)
[1] => Array
(
[0] => 2022-01-20
[1] => 1
)
[2] => Array
(
[0] => 2022-01-21
[1] => 1
)
[3] => Array
(
[0] => 2022-01-22
[1] => 2
)
)
and
Array
(
[0] => Array
(
[0] => 2022-01-17
[1] => 6
)
[1] => Array
(
[0] => 2022-01-18
[1] => 1
)
[2] => Array
(
[0] => 2022-01-21
[1] => 1
)
[3] => Array
(
[0] => 2022-01-23
[1] => 2
)
)
I need to merge them with the date and want a result array-like below
Array
(
[0] => Array
(
[0] => 2022-01-17
[1] => 0
[2] => 6
)
[1] => Array
(
[0] => 2022-01-18
[1] => 0
[2] => 1
)
[2] => Array
(
[0] => 2022-01-19
[1] => 6
[2] => 0
)
[3] => Array
(
[0] => 2022-01-20
[1] => 1
[2] => 0
)
[4] => Array
(
[0] => 2022-01-21
[1] => 1
[2] => 1
)
[5] => Array
(
[0] => 2022-01-22
[1] => 2
[2] => 0
)
[6] => Array
(
[0] => 2022-01-23
[1] => 0
[2] => 2
)
)
I tried with the below code but not any success.
$final_array = [];
foreach($openTicket as $val){
$closeTicketNo = 0;
foreach($closeTicket as $value){
if($val[0] == $value[0]){
$closeTicketNo = $value[1];
}
}
$final_array[] = [$val[0],$val[1],$closeTicketNo];
}
I get all the elements from the $openTicket but not get all the elements from a $closeTicket to my result array $final_array
This code first finds all of the unique dates (using array_unique) from the first values in each array (array_column fetches the values and array_merge puts them into 1 array).
Then it indexes each array by the dates (using array_column again).
Finally looping through the unique dates and adding a new element to the output with the values (using ?? 0 so that if no value is present the array is still filled properly)...
$dates = array_unique(array_merge(array_column($openTicket, 0), array_column($closedTicket, 0)));
$open = array_column($openTicket, 1, 0);
$closed = array_column($closedTicket, 1, 0);
$finalArray = [];
foreach ($dates as $date) {
$finalArray[] = [$date, $open[$date] ?? 0, $closed[$date] ?? 0];
}
You can try like this
$array1 = [
['2022-01-19',6],
['2022-01-20',1],
['2022-01-21',0]
];
$array2 = [
['2022-01-17',6],
['2022-01-20',2],
['2022-01-21',1]
];
function mergeMultiple($array1,$array2){
foreach($array1 as $item1){
$mergedArray[$item1[0]] = $item1;
}
foreach($array2 as $item2){
if(isset($mergedArray[$item2[0]])){
array_push($mergedArray[$item2[0]],$item2[1]);
$mergedArray[$item2[0]] = $mergedArray[$item2[0]];
}else{
$mergedArray[$item2[0]] = $item2;
}
}
return array_values($mergedArray);
}
$mergedArray = mergeMultiple($array1,$array2);
ksort($mergedArray);
print_r($mergedArray);

I want to compare the value of key[0] of each array.
If they are the same then I would like to add a new key[3] to each array with an id.
This is an array of variable products if the product has the same key[0] then its the same product with different variations.
If the key[0] is different from the previous then add id+1, in this example, I would like to end up with:
Array

can you guys help me with this?
I tried this:
but does not work
foreach ($new as $current_key => $current_array) {
foreach ($new as $search_key => $search_array) {
$ref1 = $current_array[0];
$ref2 = $search_array[0];
if (($search_key != $current_key) and ($ref1 == $ref2)) {
$current_array[3] = $p_id_product;
}
else{
$current_array[3] = $p_id_product++;
}
}
}
Assuming you have already sorted the array by the initial index, so at least they are grouped:
<?php
$data =
[
[
'foo',
'spam',
'bar',
],
[
'foo',
'eggs',
],
[
'bar',
'ham'
],
];
$output = [];
$counter = 0;
$last = null;
foreach($data as $k => $v) {
if($last !== $v[0])
$counter++;
$v[3] = $counter;
$output[$k] = $v;
$last = $v[0];
}
var_export($output);
Output:
array (
0 =>
array (
0 => 'foo',
1 => 'spam',
2 => 'bar',
3 => 1,
),
1 =>
array (
0 => 'foo',
1 => 'eggs',
3 => 1,
),
2 =>
array (
0 => 'bar',
1 => 'ham',
3 => 2,
),
)
Array
(
[content_type] => Array
(
[0] => story
[1] => delhi
[2] => tez
)
[type] => Array
(
[0] => video_id
[1] => subcategory
[2] => story_id
)
[fetch_id] => Array
(
[0] => 32
[1] => 32
[2] => 2
)
[order] => Array
(
[0] => 6
[1] => 4
[2] => 5
)
[label] => Array
(
[0] => dsfs fdsf dsf sdf
[1] => dfsdfs
[2] => sdfsdfsd
)
[link] => Array
(
[0] => fsd fsdf sdf
[1] => fsdfsdfdsf
[2] => fsdfdsfds
)
[record] => Array
(
[0] => 10
[1] => 8
[2] => 12
)
)
Above is the array I have to sort this array in the basis of order field and it should shorted all the fields accordingly like below example.
$arr['order'][0] = 4;
$arr['order'][1] = 5;
$arr['order'][2] = 6;
$arr['type'][0] = 'subcategory';
$arr['type'][1] = 'story_id';
$arr['type'][2] = 'video_id';
and so on.....
You can try this -
$new = array();
// Extract and get the keys as values
$order = array_flip($array['order']);
// sort them according to keys
ksort($order);
// loop through main array
foreach($array as $key => $sub_array) {
// loop through order
foreach ($order as $o) {
// store the new value according to order
$new[$key][] = $sub_array[$o];
}
}
Demo
Some lesser solution:
asort($array['order']);
foreach ($array as $key => $subArray) {
$array[$key] = array_replace($array['order'], $subArray);
}
For reset a key sequence you may just to use array_values().
I have an array contain this data
Array
(
[id] => Array
(
[0] => 1
[1] => 10
[2] => 4
)
[age] => Array
(
[0] => 1
[1] => 1
[2] => 2
)
)
Now I want to remove duplicates from the ['age'] and leave the first one in tact.
So this would return
Array
(
[id] => Array
(
[0] => 1
[2] => 4
)
[age] => Array
(
[0] => 1
[2] => 2
)
)
Any ideas? Or is there a function already in place to do this?
Like Gordon said, you'd need a custom function to make the relationship but you can use http://php.net/manual/en/function.array-unique.php ?
Wouldn't it be better to have the keys of the age array the corresponding values of the id array?
<?php
$array = array(
'id' => array(0 => 1, 1 => 10, 3 => 4),
'age' => array(0 => 1, 1 => 1, 2 => 2)
);
array_walk($array, 'dupe_killer');
print_r($array);
function dupe_killer(&$value, $key)
{
$value = array_unique($value);
}
?>
You could try this
$array = array('id' => array(1,10,4), 'age'=>array(1,1,2));
$age_array = array();
foreach ($array['age'] as $key => $val) {
if (in_array($val, $age_array))
unset($array['id'][$key], $array['age'][$key]);
$age_array[] = $val;
}
print_r($array);
this returns Array ( [id] => Array ( [0] => 1 [2] => 4 ) [age] => Array ( [0] => 1 [2] => 2 ) )
