I have a multidimensional array $elements where I need to fill it with values from the array $ratings. The array $ratings is built so the first value will fit into the first slot in elements, the next in the second and so on.
$elements
4 => array:3 [▼
2 => 0
3 => 0
4 => 0
]
5 => array:3 [▼
2 => 0
3 => 0
4 => 0
]
7 => array:3 [▼
2 => 0
3 => 0
4 => 0
]
I now need to fill $elements with 9 specific values from
$ratings
array:9 [▼
0 => 3
1 => 2
2 => 1
3 => 3
4 => 3
5 => 2
6 => 3
7 => 2
8 => 1
9 => 3
]
If I manage to loop through $elements, inserting values from $ratings one by one, I will have solved my problem.
So $elements[4][2] should have the value of 3, $elements[4][3] should have value of 2 etc.
Also you can manipulate these by array_fill using loop.
Try this:
<?php
$elements = [
4=>[2=>0, 3=>0, 4=>0],
5=>[2=>0, 3=>0, 4=>0],
7=>[2=>0, 3=>0, 4=>0],
];
$ratings = [ 0 => 3, 1 => 2, 2 => 1, 3 => 3, 4 => 3, 5 => 2, 6 => 3, 7 => 2, 8 => 1, 9 => 3 ];
$ratingsIndex = 0;
foreach(array_keys($elements) as $ElementsIndex) {
foreach(array_keys($elements[$ElementsIndex]) as $ElementsSubIndex) {
$elements[$ElementsIndex][$ElementsSubIndex] = $ratings[$ratingsIndex++];
}
}
echo "<pre>";
print_r($elements);
echo "</pre>";
?>

I have a 3 level category. I need to gain businesses on level 3 category.
I write this code:
$main_cat = Category::where(['slug' => $url])->first();
$lev_cat2 = Category::where(['parent_id' => $main_cat->id, 'status' => '1'])->get();
foreach ($lev_cat2 as $subCategory) {
$cat_ids_lv2[] = $subCategory->id . ',';
}
foreach ($lev_cat2 as $subCat) {
$lev_cat3[] = Category::where(['parent_id' => $subCat->id, 'status' => '1'])->pluck('id')->toArray();
}
dd($lev_cat3);
Then I got this array which is correct:
array:5 [▼
0 => array:3 [▼
0 => 145
1 => 146
2 => 147
]
1 => array:3 [▼
0 => 148
1 => 149
2 => 150
]
2 => array:3 [▼
0 => 151
1 => 152
2 => 153
]
3 => array:3 [▼
0 => 154
1 => 155
2 => 156
]
4 => []
]
now I dont know how can I get values like 145,146,147,148,149,... to pass theme to
Business::where(['category_id'=> [145,146,147,148,...]]->get();
of course dynamic.
You can use laravel collection helpers :
Business::whereIn('category_id', collect($lev_cat3)->flatten()->all())->get();
Since PHP 5.5.0 there is a built-in function array_column which does exactly this.
You can use it to Converting php array of arrays into single array then use it like this
$category_ids = array_column($lev_cat3);
Business::where(['category_id'=> $category_ids]]->get();
I want to remove same array between 2 array
1 ) $getAlldate
array:8 [▼
0 => "2018-08-17"
1 => "2018-08-20"
2 => "2018-08-21"
3 => "2018-08-22"
4 => "2018-08-23"
5 => "2018-08-24"
6 => "2018-08-27"
7 => "2018-08-28"
]
2) $getHoliday
array:7 [▼
0 => "2019-1-1"
1 => "2019-3-6"
2 => "2019-2-28"
3 => "2019-5-2"
4 => "2019-4-25"
5 => "2018-8-27"
6 => "2018-8-28"
]
As you see in my array 2018-08-27,2018-08-28 are duplicate with $getholiday I try to use array_diff and It still didnt work
$a = array_diff($getAllDate, $getHoliday);
$b = array_unique($a);
How can I output like this $getalldate remove same value $getHoliday
array:8 [▼
0 => "2018-08-17"
1 => "2018-08-20"
2 => "2018-08-21"
3 => "2018-08-22"
4 => "2018-08-23"
5 => "2018-08-24"
]
The format of both the dates are diffrent.
Try:
PHP Code:
$getAlldate = [
"2018-08-17",
"2018-08-20",
"2018-08-21",
"2018-08-22",
"2018-08-23",
"2018-08-24",
"2018-08-27",
"2018-08-28"
];
$getHoliday=[
"2019-1-1",
"2019-3-6",
"2019-2-28",
"2019-5-2",
"2019-4-25",
"2018-8-27",
"2018-8-28"
];
$formattedHoliday = array_map(function ($holiday) {
$alldateFormat = 'Y-m-d';
$HolidayFormat = 'Y-n-d';
$date = DateTime::createFromFormat($HolidayFormat, $holiday);
return $date->format($alldateFormat);
}, $getHoliday);
var_dump(array_diff($getAlldate, $formattedHoliday));
Output: https://3v4l.org/rCLCk

I've got a collection and I need the total users by month.
So I've done this:
array_replace(array_fill_keys(range(0, 11), 0), $users->groupBy('created_at.month')->toArray())
It's sort of working because I get this:
array:12 [▼
0 => 0
1 => 0
2 => 0
3 => 0
4 => 0
5 => 0
6 => array:1 [▶]
7 => array:2 [▶]
8 => 0
9 => 0
10 => 0
11 => 0
]
The problem I face now is that I don't need the 2 arrays at position 6 and 7 but I need the counts.
So I was thinking of something like:
$users->groupBy('created_at.month')->count()->toArray();
But, that's obviously not working. Any ideas ?
try using map method
$collection->map(function ($item, $key) {
return count($item);
});
I want to calculate the totals for a series of columns in a table, how do I go about doing this?
Here is a sample of the data I want to sum:
array:1 [
"traders" => array:6 [
"Jim Mayor__targeted_target" => array:2 [
"amounts" => array:13 [
0 => 5
1 => 5
2 => 0
3 => 0
4 => 0
5 => 0
6 => 0
7 => 0
8 => 0
9 => 0
10 => 0
11 => 0
]
"row_name" => "Targeted target"
]
"Jim Mayor__actual_targeted" => array:2 [
"amounts" => array:13 [
0 => 0
1 => 1
2 => 0
3 => 0
4 => 0
5 => 0
6 => 1
7 => 1
8 => 0
9 => 0
10 => 0
11 => 0
]
"row_name" => "Actual targeted"
]
"Bob Martinez__targeted_target" => array:2 [
"amounts" => array:13 [
0 => 1
1 => 0
2 => 0
3 => 0
4 => 0
5 => 0
6 => 0
7 => 0
8 => 0
9 => 0
10 => 0
11 => 0
]
"row_name" => "Targeted target"
]
"Bob Martinez__actual_targeted" => array:2 [
"amounts" => array:13 [
0 => 19
1 => 45
2 => 20
3 => 26
4 => 21
5 => 10
6 => 12
7 => 20
8 => 11
9 => 2
10 => 0
11 => 0
]
"row_name" => "Actual targeted"
]
...
I want to sum together each index, e.g. for Jim Mayor__targeted_target, index 0 added to index 0 of Bob Martinez__targeted_target (this gives the total for January). It needs to work with an unlimited number of traders.
The function that generates the data:
protected function addRow($func, $params, $data, $year, $traderName, $rowName, $type, $image = null, $format = null, $underline = false)
{
$date = Carbon::createFromDate($year, 4, 1);
$total = 0;
$traderName = $traderName . '__' . str_replace(' ', '_', strtolower($rowName));
for ($i = 1; $i < 13; $i++) {
$params[1] = $date->year;
$params[2] = $date->month;
$result = call_user_func_array($func, $params);
$data['traders'][$traderName]['amounts'][] = $result ? $result : 0;
$total += $result;
$date->addMonth();
}
$data['traders'][$traderName]['amounts'][] = $total;
$data['traders'][$traderName]['row_name'] = $rowName;
return $data;
}
Just go over your data and save results in an additional array:
$results = array();
foreach ($traders as $trader) {
foreach ($trader['amounts'] as $i => $amount) {
if (!isset($results[$i])) {
$results[$i] = 0;
}
$results[$i] += $amount;
}
}
The result array will contains the sums of all traders.
Not tested but should work.
Do something like this:
function sumRowsByMonth($traders)
{
$sums = array_fill(0, 12, 0);
foreach($traders as $trader) {
foreach($trader['amounts'] as $monthId => $amount) {
$sums[$monthId] += $amount;
}
}
return $sums;
}
I tested with this:
$arr = array(
'traders' => array(
'Jim Mayor__targeted_target' => array(
'amounts' => array(
0 => 5,
1 => 5,
2 => 0,
3 => 0,
4 => 0,
5 => 0,
6 => 0,
7 => 0,
8 => 0,
9 => 0,
10 => 0,
11 => 0,
)
),
'Bob Martinez__targeted_target' => array(
'amounts' => array(
0 => 19,
1 => 45,
2 => 20,
3 => 26,
4 => 21,
5 => 10,
6 => 12,
7 => 20,
8 => 11,
9 => 2,
10 => 0,
11 => 0,
)
),
),
);
var_dump(sumRowsByMonth($arr['traders']));
Use array_sum() function.
array_sum() returns the sum of values in an array
Also, you said you want to count targeted target and actual targeted separately.
$actual = [];
$targeted = [];
foreach ($traders as $trader) {
$sum = array_sum($trader['anmounts']);
$trader['row_name'] === 'Actual targeted') ? $actual += $sum : $target += $sum;
}
Maybe you'll need to modify this a little bit to tune behavior, but I guess I got the idea.
#imperium2335:
The main problem I keep getting that it is summing all rows, including actual_targeted. actual_targeted needs to be grouped and summed separately to targeted_target.
Then do this:
function sumRowsByMonth($traders)
{
$sums = array();
foreach($traders as $traderName => $trader) {
$type = strstr($traderName, '__');
if( empty($sums[$type]) ) {
$sums[$type] = array_fill(0, 12, 0);
}
foreach($trader['amounts'] as $monthId => $amount) {
$sums[$type][$monthId] += $amount;
}
}
return $sums;
}

I have a multidimensional array that I get from DB. Array has a number of views by each hour that is logged in the DB as a view, and it looks like this:
array:11 [▼
0 => array:2 [▼
"hour" => 0
"views" => 1
]
1 => array:2 [▼
"hour" => 1
"views" => 1
]
2 => array:2 [▼
"hour" => 4
"views" => 1
]
...and so on
]
I need to make a new array that will contain number of views for range of 2 hours. So for example from the array shown above I would like to get an array with, number of views for time between 0-2, that would 2, and for 2-4, would be 0 in this case, and so on.
You can do it in Mysql query:
select floor(hour/2) range, sum(views) sum
from thetable
group by range
You can just use a foreach to create a new array.
<?php
$your_array = [0 => [
"hour" => 0,
"views" => 4
],
1 => [
"hour" => 1,
"views" => 12
],
2 => [
"hour" => 4,
"views" => 1
],
3 => [
"hour" => 2,
"views" => 9
],
4 => [
"hour" => 21,
"views" => 19
]
];
foreach ($your_array as $value){
for($i=0;$i<=22;$i=$i+2){
$j=$i+2;
if($value['hour']>=$i && $value['hour']<$j){
isset($result[$i.'-'.$j])?$result[$i.'-'.$j]+=$value['views']:$result[$i.'-'.$j]=$value['views'];
}
}
}
print_r($result);
Try below code.
$arr = [0 => [
"hour" => 0,
"views" => 1
],
1 => [
"hour" => 1,
"views" => 1
],
2 => [
"hour" => 4,
"views" => 1
]];
foreach($arr as $row)
{
if($row['hour'] >= 0 && $row['hour'] <= 2)
{
$newArr['0-2'] = isset($newArr['0-2']) ? ($newArr['0-2'] + 1) : 1;
}
if($row['hour'] > 2 && $row['hour'] < 4)
{
$newArr['2-4'] = isset($newArr['2-4']) ? ($newArr['2-4'] + 1) : 1;
}
}
print_r($newArr);
Output
Array
(
[0-2] => 2
)
