I have the following arrays:
array:2 [▼
0 => array:2 [▼
"id" => 3
"total" => 2
]
1 => array:2 [▼
"id" => 4
"total" => 1
]
]
and
array:2 [▼
0 => array:2 [▼
"id" => 3
"total" => 5
]
1 => array:2 [▼
"id" => 4
"total" => 5
]
2 => array:2 [▼
"id" => 5
"total" => 2
]
]
I need to merge them together, keeping ids and summing the results, so I would get the resulting array as:
array:2 [▼
0 => array:2 [▼
"id" => 3
"total" => 7
]
1 => array:2 [▼
"id" => 4
"total" => 6
]
2 => array:2 [▼
"id" => 5
"total" => 2
]
]
These arrays come from a laravel database query using the toArray() method, so answers containing laravel default collection methods are welcome too.
try this
arr3 = arr1->merge(arr2);
arr3->map(function(itemM)use(arr1, arr2){
return itemM->total = arr1->sum(function(itemS)use(itemM){
return itemS->id == itemM->id ? itemS->total : 0;
}) +
arr2->sum(function(itemS)use(itemM){
return itemS->id == itemM->id ? itemS->total : 0;
});
})

This dump:
dd($moviesInformation['movies']['data'][1]['genres']);
show all genres for each movie returned like this:
^ array:2 [▼
"data" => array:32 [▼
0 => array:3 [▶]
1 => array:3 [▶]
2 => array:3 [▼
"id" => 446
"genre" => array:1 [▼
"label" => "Comedy"
]
"on_request" => 1
]
3 => array:3 [▶]
4 => array:3 [▶]
5 => array:3 [▶]
And I want to, based on this, have an output with all genres separated by ",", like this:
'result' => [Comedy, Action, etc],
However doing like this:
collect($moviesInformation['movies']['data'])->map(function ($movie) {
return [
'result' => implode(',', $movie['genres'])
];
});
Im getting "Array to string conversion". Do you know how to properly achieve that?
i have an array that contains another array and i wanna get specifics elements sum

"quantity" => 2
]
]
]
]
i need to get the sum of price
any ideas to do this?
If there is relationships there is a better approach. As the data you have given you could call sum twice and make it work.
collect($array)->sum(function (array $shop) {
return collect($shop['items'])->sum('price');
});
This will sum each individual shop and the sum amount would be the sum of each shops items.

I wish you could help me ...
I have 2 arrays, which I would like to insert into a 1array, by new_date to which if there is no data is data = '0', if there is no data1 is data1 = '0'.
Sorry if I do not know how to explain it well, I gave a small example. I have already tried array_merge (but everything is separate) and array_combine (it gives an error of Both parameters should have an equal number of elements).
Thank you in advance for all the help you can give ...
array1 = array:5 [▼
0 => array:2 [▼
"data" => 118
"new_date" => "06-2017"
]
1 => array:2 [▼
"data" => 263
"new_date" => "07-2017"
]
2 => array:2 [▼
"data" => 264
"new_date" => "08-2017"
]
3 => array:2 [▼
"data" => 266
"new_date" => "09-2017"
]
4 => array:2 [▼
"data" => 306
"new_date" => "10-2017"
]
5 => array:2 [▼
"data" => 100
"new_date" => "11-2017"
]
array2 = array:6 [▼
0 => array:2 [▼
"data1" => 100

Use array_combine to set the new_date as keys. Then add the first array element the d1 (as "data1" in your example) with array_map. Finely, loop on second array and add d1 is exist and all the rest with d ("data" in your example) as 0 if not.
You can do it like this:
$a1 = array(["d"=>1, "new_date"=> "06-2017"],["d"=>2, "new_date"=> "02-2016"]);
$a2 = array(["d1"=>3, "new_date"=> "06-2017"],["d1"=>4, "new_date"=> "07-2017"]);
$a1 = array_combine(array_column($a1, "new_date"), $a1);
$a2 = array_combine(array_column($a2, "new_date"), $a2);
// adding default d1 as 0
$a1 = array_map(function ($e) {return array_merge($e, ["d1" => 0]);},$a1);
foreach($a2 as $k => $v) {
if (isset($a1[$k]))
$a1[$k]["d1"] = $v["d1"]; // if new_data exist set only d1
else
$a1[$k] = array_merge($v, ["d" => 0]); //add with d as 0
}
Your result will be in $a1

Please help me how i will combine the array ,I want to push 2nd array element if not fund in first array key.I trying but not clear to make new array. I have tried array merge and array combine but not clear to make this new array.
Use array_merge() function Example below
<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>
Output like this:
Array
(
[color] => green
[0] => 2
[1] => 4
[2] => a
[3] => b
[shape] => trapezoid
[4] => 4
)
I am trying to create an array that succinctly gives me the following:
ID of a component part
ID of the supplier for that component part
The volume breakpoints, and their associated unit costs
I am using Laravel 5.2, although this is a more general PHP question.
So, I have a database table that looks like this:
I have a function, as below, to get some prices of components:
public function get_component_prices()
{
$components = DB::table('component_supplier')
->select('component_id', 'supplier_id', 'volume', 'unit_cost')
->get();
$prices = [];
foreach ($components as $component) {
array_push($prices, ["component_id" => $component->component_id, "supplier_id" => $component->supplier_id, "volumes" => [$component->volume => $component->unit_cost]]);
}
dd($prices);
}
This gives me the array:
array:7 [▼
0 => array:3 [▼
"component_id" => 3
"supplier_id" => 1
"volumes" => array:1 [▼
100 => "1.5000"
]
]
1 => array:3 [▼
"component_id" => 3
"supplier_id" => 1
"volumes" => array:1 [▼
207 => "1.0100"
]
]
2 => array:3 [▼
"component_id" => 3
"supplier_id" => 1
"volumes" => array:1 [▼
500 => "0.8000"
]
]
3 => array:3 [▼
"component_id" => 3
"supplier_id" => 1
"volumes" => array:1 [▼
1000 => "0.4000"
]
]
4 => array:3 [▼
"component_id" => 3
"supplier_id" => 2
"volumes" => array:1 [▼
10000 => "0.2000"
]
]
5 => array:3 [▼
"component_id" => 4
"supplier_id" => 2
"volumes" => array:1 [▼
100 => "0.1000"
]
]
6 => array:3 [▼
"component_id" => 4
"supplier_id" => 2
"volumes" => array:1 [▼
500 => "0.0700"
]
]
]
You can see that certain suppliers and components have multiple volumes.
Therefore, I'd like to try to group the array a bit better, combining the repeated parts - perhaps like so, for example:
6 => array:3 [▼
"component_id" => 4
"supplier_id" => 2
"volumes" => array:3 [▼
100 => "0.1000",
500 => "0.0700"
]
]
So that for each component_id and supplier_id group, there's a set of 'volumes'.
Any advice is much appreciated... I have been trying for hours to get the array sorted!
In Mysql, you can do something like this
SELECT component_id, supplier_id,
GROUP_CONCAT(volume, ':', unit_cost) AS volumes
FROM component_supplier
GROUP BY CONCAT(component_id, supplier_id)
http://sqlfiddle.com/#!9/cb7bb/1
Then you can simply loop this query in PHP and explode volumes field by the comma.
