I have this array with certain brand_ids, within these brands I have an array of dates in which a sale occured but these are based on the products in sale so they may appear multiple times on the same brand_id;
This is my array:
array:5 [▼
2 => array:3 [▼
0 => "2022-05-08"
1 => "2022-05-08"
2 => "2022-05-08"
]
3 => array:5 [▼
0 => "2022-05-08"
1 => "2022-05-08"
2 => "2022-05-08"
3 => "2022-05-08"
4 => "2022-05-08"
]
4 => array:1 [▼
0 => "2022-05-08"
]
1 => array:3 [▼
0 => "2022-05-01"
1 => "2022-05-08"
2 => "2022-05-08"
]
6 => array:3 [▼
0 => "2022-05-08"
1 => "2022-05-08"
2 => "2022-05-08"
]
]
The code to generate this :
pastSales = [];
$historySales = SaleHistoryCount::all()->toArray();
foreach($historySales as $key => $historySale) {
$saleDateToCompare = Carbon::createFromFormat('Y-m-d H:i:s', $historySale['sale_date'])
->format('Y-m-d');
if(in_array($saleDateToCompare , $saleDays)) {
if(! isset($pastSales[$historySale['sale_date']])) {
$pastSales [$historySale['brand_id']][] = Carbon::createFromFormat('Y-m-d H:i:s', $historySale['brand_id'])
->format('Y-m-d');
}
}
}
$saleDays is a 2D array of every sunday untill a certain year like so
[
"2022-05-08"
"2022-05-15"
"2022-05-22"
]
All the duplicates stripped out and have it reduced to one unless the date is different per brand_id but I can't seem to be able to produce that with array_unique, array_mapping and/or array_columns... How would I achieve the output below?
array:5 [▼
2 => array:3 [▼
0 => "2022-05-08"
]
3 => array:5 [▼
0 => "2022-05-08"
]
4 => array:1 [▼
0 => "2022-05-08"
]
1 => array:3 [▼
0 => "2022-05-01"
2 => "2022-05-08"
]
6 => array:3 [▼
0 => "2022-05-08"
]
]
Use in_array as Tim Lewis proposed:
foreach($historySales as $key => $historySale) {
$saleDateToCompare = Carbon::createFromFormat('Y-m-d H:i:s', $historySale['sale_date'])
->format('Y-m-d');
if(in_array($saleDateToCompare , $saleDays)) {
$date_formatted = Carbon::createFromFormat('Y-m-d H:i:s', $historySale['brand_id'])->format('Y-m-d');
// !!! Is this string correct? Maybe we should check for "$historySale['brand_id']" existance?
if(! isset($pastSales[$historySale['sale_date']]))
$pastSales[$historySale['brand_id']] = [];
if( !in_array($date_formatted, $pastSales[$historySale['brand_id']]) )
$pastSales[$historySale['brand_id']][] = $date_formatted;
}
}

I wanted to insert the id values of $courseCat if that id is not present in $m.In the below code, i feel the $m array is getting emptied every time and so, all id's are getting inserted to the $m ,as the result of dump($m) indicates.How can i fix this?
$m=[];
$courseCat = MyCourse::where('course_id', $key['courseId'])->get()->toArray();
foreach($courseCat as $k=>$c){
// dump($courseCat);
if(!in_array($c['id'],$m)){
array_push($m,$c['id']);
}
}
//dump($m);
dump($courseCat); shows the following result
array:2 [
0 => array:19 [
"id" => 2
"course_id" => 18
]
1 => array:19 [
"id" => 3
"course_id" => 18
]
]
array:2 [
0 => array:19 [
"id" => 2
"course_id" => 18
]
1 => array:19 [
"id" => 3
"course_id" => 18
]
]
array:2 [
0 => array:19 [
"id" => 5
"course_id" => 1
]
1 => array:19 [
"id" => 6
"course_id" => 1
]
]
array:2 [
0 => array:19 [
"id" => 5
"course_id" => 1
]
1 => array:19 [
"id" => 6
"course_id" => 1
]
]
dump($m) shows the below result:
array:2 [
0 => 2
1 => 3
]
array:2 [
0 => 2
1 => 3
]
array:2 [
0 => 6
1 => 5
]
array:2 [
0 => 6
1 => 5
]
Below attached images are the result of the query MyCourse::where('course_id', $key['courseId'])->get().
[enter image description here]1
[enter image description here]2
[enter image description here]3
Expected result :
dump($m) should show the below result
[0=>2,
1=>3,
2=>5,
3=>6]
I think it's because you have an outer loop not shown in the question. You need to declare $m before the outer loop:
$m=[];
foreach($keys as $key){
$courseCat = MyCourse::where('course_id', $key['courseId'])->get()->toArray();
foreach($courseCat as $k=>$c){
if(!in_array($c['id'],$m)){
array_push($m,$c['id']);
}
}
}
dump($m);
If you want all the values of a column from your query you can use pluck:
MyCourse::where('course_id', $key['courseId'])->pluck('id')
Now you have a list of all the 'id's.

i am attempting to make an array:
foreach ($cats as $cat) {
$catsList[$cat->id] = [$cat->info => $cat->info];
}
What i get is a resulting array that only contains the last $cat info.
array:2 [▼
10 => array:1 [▼
23 => 23
]
9 => array:1 [▼
11 => 11
]
]
What i expect to get is:
array:2 [▼
10 => array:1 [▼
23 => 23
15 => 15
12 => 12
]
9 => array:1 [▼
11 => 11
24 => 24
]
]
I guess the syntax is wrong when i'm trying to add a new member and it just overwrites the old one?
Can you try this:
foreach ($cats as $cat) {
$catsList[$cat->id][$cat->info] = $cat->info;
}

This question already has answers here:
PHP's array_merge_recursive behaviour on integer keys
(5 answers)
Closed 5 months ago.
I have 2 arrays, each will always have the same number of rows and same number of values per row.
I need to merge the 2 arrays together, to combine the results on each row, but in a particular way (there will always be only 3 results per row on each array too):
For example, for each row, take the first result of each array, and put them next to each other, then the second result of each array, and put them next to each other, then finally the third.
So Array 1's value will always precede Array 2's value (example shown below):
Array 1:
array:7 [▼
24 => array:3 [▼
0 => 0
1 => 0.66666666666667
2 => 0.66666666666667
]
25 => array:3 [▶]
26 => array:3 [▶]
27 => array:3 [▶]
29 => array:3 [▶]
30 => array:3 [▶]
31 => array:3 [▶]
]
Array 2:
array:7 [▼
24 => array:3 [▼
0 => 0.375
1 => 0.42857142857143
2 => 0.55555555555556
]
25 => array:3 [▶]
26 => array:3 [▶]
27 => array:3 [▶]
29 => array:3 [▶]
30 => array:3 [▶]
31 => array:3 [▶]
]
Intended Combined Array Format:
array:7 [▼
24 => array:6 [▼
0 => 0
1 => 0.375
2 => 0.66666666666667
3 => 0.42857142857143
4 => 0.66666666666667
5 => 0.55555555555556
]
25 => array:6 [▶] ...
Current loop which returns the incorrect layout:
$results = array();
foreach ($questionDetails as $key => $question) {
for ($i = 0; $i < 3; $i++) {
$results[$key][] = $array1[$key] + $array2[$key];
}
}
Returns:
array:7 [▼
24 => array:3 [▼
0 => array:3 [▼
0 => 0
1 => 0.66666666666667
2 => 0.66666666666667
]
1 => array:3 [▼
0 => 0
1 => 0.66666666666667
2 => 0.66666666666667
]
2 => array:3 [▼
0 => 0
1 => 0.66666666666667
2 => 0.66666666666667
]
]
25 => array:3 [▶]
26 => array:3 [▶]
27 => array:3 [▶]
29 => array:3 [▶]
30 => array:3 [▶]
31 => array:3 [▶]
]
I'm unsure why my loop isn't just adding the three values from each row together - but then I think they still won't be in the right order, but I'm unsure of how to approach this.
Many thanks.
This is the "unfancy" (but save) solution if I understand your question correctly - all keys are preserved an set as desired:
$array1;
$array2;
$results = array();
foreach ($questionDetails as $key => $question1) {
$question2 = $array2[$key];
$tp = array();
$tp[0] = $question1[0];
$tp[1] = $question2[0];
$tp[2] = $question1[1];
$tp[3] = $question2[1];
$tp[4] = $question1[2];
$tp[5] = $question2[2];
$results[$key] = $tp;
}
EDIT: There is a way more flexible way to implement this where the number of arguments may vary (see PHP: array_merge() in alternate order (zip order)?).
$array1;
$array2;
function array_zip(...$arrays) {
return array_merge(...array_map(null, ...$arrays));
}
$results = array();
foreach ($questionDetails as $key => $question1) {
$results[$key] = array_zip($question1,$array2[$key]);
}
I would do this:
$combined = array();
foreach($array1 as $key => $value){
$combined[$key] = array();
foreach($value as $key2 => $value2){
$combined[$key][] = $value2;
$combined[$key][] = $array2[$key][$key2];
}
}

Here is the array. What I want is I wanna sort the array on the basis on 'income_difference' in ascending order. If possible, I just want 3 data with least income difference.
array:5 [▼
0 => array:4 [▼
"month" => "11"
"income_times" => 2
"income_amount" => 52300
"income_difference" => 49000
]
1 => array:4 [▼
"month" => "10"
"income_times" => 1
"income_amount" => 50000
"income_difference" => 46700
]
2 => array:4 [▼
"month" => "09"
"income_times" => 1
"income_amount" => 5000000
"income_difference" => 4996700
]
3 => array:4 [▼
"month" => "08"
"income_times" => 1
"income_amount" => 50000
"income_difference" => 46700
]
4 => array:4 [▼
"month" => "06"
"income_times" => 1
"income_amount" => 5200
"income_difference" => 1900
]
]
Use usort:
usort($data, function($a, $b) {
return $a['income_difference'] - $b['income_difference'];
});
If you don't want to maintain the index(0,1,2,3) you can use usort
e.g
function cmp($a, $b)
{
if ($a['income_difference'] == $b['income_difference']) {
return 0;
}
return ($a['income_difference'] < $b['income_difference']) ? -1 : 1;
}
usort($yourArray,'cmp')
If you want to maintain the index (0,1,2,3) you can use uasort instead of usort. Other syntax remains the same.
For more details on functionality please refer usort
