I have two result arrays in controller. I want to check whether the values in the first array are present in the second array or not and display those values which are in both arrays and which are not, under different names.My two result arrays are :
$res['c'] = $this->insert_model->content();
$res['q'] = $this->insert_model->diffpan();
You can use array_intersect() and array_diff
array_diff Compares array1 against one or more other arrays and returns the values in array1 that are not present in any of the other arrays.
$array1 = array("a" => "green", "red", "blue", "red");
$array2 = array("b" => "green", "yellow", "red");
$result = array_diff($array1, $array2); //Array([1] => blue);
array_intersect returns an array containing all the values of array1 that are present in all the arguments. Note that keys are preserved.
$array1 = array("a" => "green", "red", "blue");
$array2 = array("b" => "green", "yellow", "red");
$result = array_intersect($array1, $array2); //Array( [a] => green [0] => red)
With your given values
$array1=array('4','3','2');
$array2= array('4','3');
print_r(array_diff($array1,$array2));
OutPut : Array ( [2] => 2 )
$array1=array('4','3','2');
$array2= array('4','3');
print_r(array_intersect($array1,$array2));
OutPut : Array ( [0] => 4 [1] => 3 )

How to access the items listed in an Illuminate\Validation\Rules\In variable ?
use Illuminate\Validation\Rules\In;
$foo = Rule::in('a', 'b');
$foo->toString() // error
The only way I found to show it is:
>>> dump($foo)
Illuminate\Validation\Rules\In^ {#3512
#rule: "in"
#values: array:2 [
0 => "a"
1 => "b"
]
}
you can convert that Illuminate\Validation\Rules\In to collection then take the result array:
$foo = Rule::in('a', 'b');
$values = collect($foo)->values()[1];
to get the string Representation from it:
$stringRepresentation=$foo->__toString();
I have an array that plucks values to an array like so:
/* Pluck just the wattage values to an array */
$realtime_data_array = $latestrtfeed->nth(60)->reverse()->pluck('data')->toArray();
which results in:
array:150 [▼
0 => 20277.6
1 => 20281.4
2 => 20285.3
3 => 20289.7
4 => 20293.8
5 => 20298.6
6 => 20303.2
7 => 20307.4
8 => 20311.5
9 => 20315.8
10 => 20319.8
these value get inputted to the chart like so:
$realtime_consumption_chart->dataset('kWh', 'line', $realtime_data_array);
The problem is that the sensor is storing cumulative values and I only want to show the difference between value 0 and value 1 then difference between value 1 and value 2 and so on and so on.
How would I go about something like that?
I am going to take a shot and say that I'm going to have to do a FOREACH on the array and create a new array with the values adjusted, but how do I go about that? maybe:
foreach ($realtime_data_array as $data) {
$realtime_data_array_corrected = ($data[1]-$data[0])->toArray();
}
Nope there is something I'm doing wrong or not considering here.
for ($i = 0; $i < sizeof($realtime_data_array); $i++) {
if($i==0) {
$realtime_data_array_corrected[$i] = 0;
continue;
}
$realtime_data_array_corrected[$i] = $realtime_data_array[$i] - $realtime_data_array[$i-1];
}
My issue is in my json I am expecting an array, but am getting an object.
Details:
I have an array of numbers:
$numbers = [1];
I select from relationship, the "drawn numbers":
$drawnNumbers = Ball::whereIn('number', $numbers)->where('game_id', $card->game->id)->get()->map(function($ball) {
return $ball->number;
})->toArray();
I do a ->toArray() here. I want to find the numbers in $numbers that do not occur in $drawnNumbers. I do so like this:
$numbersNotYetDrawn = array_diff($numbers, $drawnNumbers);
My method then return $numbersNotYetDrawn (my headers accept is application/json).
So now the issue. When $drawnNumbers is an empty array, then the printed json is a regular array like this:
[
1
]
However if the relationship returns $drawnNumbers to be an array with numbers, then json is printed as an object:
{
"0" => 1
}
Does anyone know why this is? Anyway to ensure that json is array?
Edit:
Here is my actual data:
$drawnNumbers = Ball::whereIn('number', $numbers)->where('game_id', $card->game->id)->get()->map(function($ball) {
return $ball->number;
})->toArray();
$undrawnNumbers = array_diff($numbers, $drawnNumbers);
// $undrawnNumbers = array_values(array_diff($numbers, $drawnNumbers)); // temp fix
Replace
$numbersNotYetDrawn = array_diff($numbers, $drawnNumbers);
with
$numbersNotYetDrawn = array_values(array_diff($numbers, $drawnNumbers));
to make sure element keys are reset and array is treated as a simple list and serialized to a JSON list - instead of being treated as an associative array and serialized to a JSON object.
I recently had this same problem and wondered the same thing.
I solved it by adding "array_values", but I was wondering how to reproduce it.
I found it that it is reproduced when array_diff removes an element from the array that isn't the last element. So:
>>> $x
=> [
1,
2,
3,
4,
5,
]
>>> array_diff($x, [5]);
=> [
1,
2,
3,
4,
]
>>> array_diff($x, [1]);
=> [
1 => 2,
2 => 3,
3 => 4,
4 => 5,
]
I have collection of Products with property Brand and 2 unique values:
"Super brand A"
"Super brand B"
ES query
var response = new ElasticClient().Search<DTO>(s => s
.Index("index")
.Type("type")
.Aggregations(a => a
.Terms("unique", t => t
.Field(f => f.Brand)
//.Field(f => f.Brand.Suffix("keyword"))
.Size(1000)
)
)
);
var brands = (((BucketAggregate)response.Aggregations.First().Value).Items).Cast<KeyedBucket<Object>>().Select(x => x.Key).ToList();
ES returns 4 invalid values
"Super"
"brand"
"A"
"B"
I've tried to force full property match by adding .Suffix("keyword") to field but then it returns empty list. How can I get 2 distinct values?
How do you index products like that in ElasticSearch? We've separated all documents based on the attributes (colour, brand, size, whatever users input), but all of them belong to a set of categories. May be one, may be 15.
[0] => Array
(
[product_id] => 123456
[product_name] => Shirt 1
[filter_name] => Colour
[filter_value] => Blue
[product_parent_id] => 111111
[product_has_discount] => 0
[product_price] => 19.99
[product_stock] => 1
)
[1] => Array
(
[product_id] => 123457
[product_name] => Shirt 1
[filter_name] => Colour
[filter_value] => Red
[product_parent_id] => 111111
[product_has_discount] => 0
[product_price] => 19.99
[product_stock] => 1
)
How would we tag categories into this? Would it be so simple as saying
[product_categories] => ;4750;4834;4835;4836;
And then querying ElasticSearch with match against category with the value ;4836;? Is that possible? Recommended?
You can define product_categories as integer in your mapping and pass in the category values as array like
[product_categories] => array(4750,4834,4835,4836)
EDIT: You read more about mapping here. A more specific to mapping an array type.
Once your data is indexed like that you can query, filter, aggregate on the field product_categories easily in all combinations.
for example to match products in category 4750 or 4750:
{
"filter": {
"terms": {
"product_categories": [
4750,
4750
]
}
}
}
