Background
We have this table lead_activity in our mysql database, with following fields
1. id
2. lead_id
3. activity
example of rows:
id
lead_id
activity
1
5
Called
2
5
Selled
3
6
Contacted
4
9
Contacted
In Laravel, I have got following query:
$this->data['lead_activities'] = LeadActivity::select(DB::Raw('count(*) as total'), 'activity')->groupBy('activity')->get();
With this result:
[
0 => [
'total' => 1,
'activity' => 'Called'
],
1 => [
'total' => 1,
'activity' => 'Selled'
],
2 => [
'total' => 2,
'activity' => 'Contacted'
],
]
Request
How can I build this query (whether Eloquent or raw SQL) so have something similar to these results within just one Query, without any for each after:
[
0 => [
'total' => 1,
'activity' => 'Called',
'lead_ids' => [5]
],
1 => [
'total' => 1,
'activity' => 'Selled'
'lead_ids' => [5],
],
2 => [
'total' => 2,
'activity' => 'Contacted',
'lead_ids' => [6,9]
],
]
Have a look at the MySQL GROUP_CONCAT() function.
I think that should solve your problem. Its not returning you an array of lead_ids but a concatenation (string) of all lead_ids, you can work with (transform to array eventually) afterwards.
$list = LeadActivity::select(DB::Raw('count(*) as total'), 'activity','GROUP_CONCAT(lead_id) as lead_id_aggr')
->groupBy('activity')
->get();
reference: https://dev.mysql.com/doc/refman/8.0/en/aggregate-functions.html#function_group-concat
You can try this:
LeadActivity::query()
->select(
'activity',
DB::raw('GROUP_CONCAT(lead_id) as leads'),
DB::raw('COUNT(*) as activities_count'),
)->groupBy('activity')
->get();
which would produce this result:
Illuminate\Database\Eloquent\Collection {#2057
all: [
App\Models\LeadActivity {#2059
activity: "Called",
leads: "5",
activities_count: 1,
},
App\Models\LeadActivity {#2060
activity: "Contacted",
leads: "6,9",
activities_count: 2,
},
App\Models\LeadActivity {#2061
activity: "Sold",
leads: "5",
activities_count: 1,
},
],
}
I have below two dimentional array
$data = [
['category'=>1,'attribute'=>1,'option'=>1],
['category'=>1,'attribute'=>1,'option'=>2],
['category'=>1,'attribute'=>2,'option'=>3],
['category'=>1,'attribute'=>2,'option'=>4],
['category'=>2,'attribute'=>3,'option'=>5],
['category'=>2,'attribute'=>3,'option'=>6],
['category'=>2,'attribute'=>4,'option'=>7],
['category'=>2,'attribute'=>4,'option'=>8]
];
And I want to convert this array into Three dimentional according to Parent-Child value like below array.
$data = [
'1'=>[
'1' => [
'1' => 1,
'2' => 2
],
'2' => [
'3' => 3,
'4' => 4
]
],
'2'=>[
'3' => [
'5' => 5,
'6' => 6
],
'4' => [
'7' => 7,
'8' => 8
]
],
];
In this first iterator is value of 'category' key which iterate two times. second iteration is for 'attribute' and likewise third is for 'option', which iterate 8 times.
Addition: What if I want to do reverse. I have second array and want to convert in first one.
Thanks.
$arr = [
['category'=>1,'attribute'=>1,'option'=>1],
['category'=>1,'attribute'=>1,'option'=>2],
['category'=>1,'attribute'=>2,'option'=>3],
['category'=>1,'attribute'=>2,'option'=>4],
['category'=>2,'attribute'=>3,'option'=>5],
['category'=>2,'attribute'=>3,'option'=>6],
['category'=>2,'attribute'=>4,'option'=>7],
['category'=>2,'attribute'=>4,'option'=>8],
];
$newArr = [];
foreach($arr as $arrRow) {
$newArr[$arrRow['category']][$arrRow['attribute']][$arrRow['option']] = $arrRow['option'];
}
Strings with numbers for array keys will be converted to int in PHP.
** I have edited this to show how I got my code to work using array_search
I have an array, $arr1 with 5 columns as such:
key id name style age whim
0 14 bob big 33 no
1 72 jill big 22 yes
2 39 sue yes 111 yes
3 994 lucy small 23 no
4 15 sis med 24 no
5 16 maj med 87 yes
6 879 Ike larg 56 no
7 286 Jed big 23 yes
This array is in a cache, not a database.
I then have a second array with a list of id values -
$arr2 = array(0=>14, 1=>72, 2=>8790)
How do I filter $arr1 so it returns only the rows with the id values in $arr2?
I got my code to work as follows:
$arr1 = new CachedStuff(); // get cache
$resultingArray = []; // create an empty array to hold rows
$filter_function = function ($row) use ($arr2) {
return (array_search($row['id'], $arr2));
};
$resultingArrayIDs = $arr1->GetIds($filter_function, $resultingArray);
This gives me two outputs: $resultingArray & $resultingArrayIDs both of which represent the intersection of the $arr1 and $arr2.
This whole task can be accomplished with just one slick, native function call -- array_uintersect().
Because the two compared parameters in the custom callback may come either input array, try to access from the id column and if there isn't one declered, then fallback to the parameter's value.
Under the hood, this function performs sorting while evaluating as a means to improve execution time / processing speed. I expect this approach to outperform iterated calls of in_array() purely from a point of minimized function calls.
Code: (Demo)
var_export(
array_uintersect(
$arr1,
$arr2,
fn($a, $b) =>
($a['id'] ?? $a)
<=>
($b['id'] ?? $b)
)
);
Something like this should do it, provided I've understood your question and data structure correctly:
$dataArray = [
[ 'key' => 0, 'id' => 14 , 'name' => 'bob' , 'style' => 'big' , 'age' => 33 , 'whim' => 'no' ],
[ 'key' => 1, 'id' => 72 , 'name' => 'jill' , 'style' => 'big' , 'age' => 22 , 'whim' => 'yes' ],
[ 'key' => 2, 'id' => 39 , 'name' => 'sue' , 'style' => 'yes' , 'age' => 111 , 'whim' => 'yes' ],
[ 'key' => 3, 'id' => 994 , 'name' => 'lucy' , 'style' => 'small' , 'age' => 23 , 'whim' => 'no' ],
[ 'key' => 4, 'id' => 15 , 'name' => 'sis' , 'style' => 'med' , 'age' => 24 , 'whim' => 'no' ],
[ 'key' => 5, 'id' => 16 , 'name' => 'maj' , 'style' => 'med' , 'age' => 87 , 'whim' => 'yes' ],
[ 'key' => 6, 'id' => 879 , 'name' => 'Ike' , 'style' => 'larg' , 'age' => 56 , 'whim' => 'no' ],
[ 'key' => 7, 'id' => 286 , 'name' => 'Jed' , 'style' => 'big' , 'age' => 23 , 'whim' => 'yes' ]
];
$filterArray = [14, 72, 879];
$resultArray = array_filter( $dataArray, function( $row ) use ( $filterArray ) {
return in_array( $row[ 'id' ], $filterArray );
} );

However, your question appears to suggest this data might be coming from a database; is that correct? If so, perhaps it's more efficient to pre-filter the results at the database-level. Either by adding a field in the SELECT query, that represents a boolean value whether a row matched your filter ids, or by simply not returning the other rows at all.
One way is with foreach loop with array_search()
$result = [];
foreach ($arr1 as $value) { // Loop thru $arr1
if (array_search($value['id'], $arr2) !== false) { // Check if id is in $arr2
$result[] = $value; // Push to result if true
}
}
// print result
print_r($result);
As #DecentDabbler mentioned - if the data is coming out of a database, using an IN on your WHERE will allow you to retrieve only the relevant data.
Another way to filter is to use array functions
array_column extracts the value of the id column into an array
array_intersect returns the elements which are in both $arr1['id'] and $arr2
array_flip flips the resulting array such that the indices into $arr1 indicate the elements in both $arr1 and $arr2
$arr1 = [ [ 'id' => 14, 'name' => 'bob'],
['id' => 72, 'name' => 'jill'],
['id' => 39, 'name' => 'sue'],
['id' => 994, 'name' => 'lucy'],
['id' => 879, 'name'=> 'large']];
$arr2 = [ 14,72,879 ];
$intersection = array_flip(array_intersect(array_column($arr1,'id'),$arr2));
foreach ($intersection as $i) {
var_dump($arr1[$i]);;
}
I have an array based MySql database.
This is the array.
[
0 => [
'id' => '1997'
'lokasi_terakhir' => 'YA4121'
]
1 => [
'id' => '1998'
'lokasi_terakhir' => 'PL2115'
]
2 => [
'id' => '1999'
'lokasi_terakhir' => 'PL4111'
]
]
How can I get the element lokasi_terakhir that grouped by the first character ? What the best way ?
This is the goal :
[
"Y" => 1,
"P" => 2
]
Please advise
Here are two refined methods. Which one you choose will come down to your personal preference (you won't find better methods).
In the first, I am iterating the array, declaring the first character of the lokasi_terakhir value as the key in the $result declaration. If the key doesn't yet exist in the output array then it must be declared / set to 1. After it has been instantiated, it can then be incremented -- I am using "pre-incrementation".
The second method first maps a new array using the first character of the lokasi_terakhir value from each subarray, then counts each occurrence of each letter.
(Demonstrations Link)
Method #1: (foreach)
foreach($array as $item){
if(!isset($result[$item['lokasi_terakhir'][0]])){
$result[$item['lokasi_terakhir'][0]]=1; // instantiate
}else{
++$result[$item['lokasi_terakhir'][0]]; // increment
}
}
var_export($result);
Method #2: (functional)
var_export(array_count_values(array_map(function($a){return $a['lokasi_terakhir'][0];},$array)));
// generate array of single-character elements, then count occurrences
Output: (from either)
array (
'Y' => 1,
'P' => 2,
)
You can group those items like this:
$array = [
0 => [
'id' => '1997',
'lokasi_terakhir' => 'YA4121'
],
1 => [
'id' => '1998',
'lokasi_terakhir' => 'PL2115'
],
2 => [
'id' => '1999',
'lokasi_terakhir' => 'PL4111'
]
];
$result = array();
foreach($array as $item) {
$char = substr($item['lokasi_terakhir'], 0, 1);
if(!isset($result[$char])) {
$result[$char] = array();
}
$result[$char][] = $item;
}
<?php
$array=[
0 => [
'id' => '1997',
'lokasi_terakhir' => 'YA4121'
],
1 => [
'id' => '1998',
'lokasi_terakhir' => 'PL2115'
],
2 => [
'id' => '1999',
'lokasi_terakhir' => 'PL4111'
]
];
foreach($array as $row){
$newArray[]=$row['lokasi_terakhir'][0];
}
print_r(array_flip(array_unique($newArray)));
this code gets the first letter of the fields lokasi_terakhir , get the unique values to avoid duplicates and just flips the array to get the outcome you want.
The output is this :
Array ( [Y] => 0 [P] => 1 )
I have "_id" and "ProductLot". How can I Update Qty "0" to "1 " in the Lot array if ProductLot if present or append a new Lot element if it is not present?
"_id" : ObjectId("5462e44c599e5c6c1300000a"),
"LocationName" : "Putaway",
"Owner" : "",
"Status" : "1",
"Scrap" : "0",
"Lot" : [{
"Qty" :"6",
"ProductLot" : ObjectId("5462dbd9599e5c200e000000"),
"Product" : ObjectId("543ca7be4cf59d400c000004"),
"Movement" :[ {"OriginId" : "266",Qty:2,Type:"DN"},
{"OriginId" : "267" , Qty:1 , Type:"DN"},
{"OriginId" : "2" , Qty:3 , Type:"IM"},
]
},
{
"Qty" :"0",
"ProductLot" : ObjectId("5462dbd9599e5c200e000003"),
"Product" : ObjectId("543ca7be4cf59d400c000004"),

{"OriginId" : "267" , Qty:1 , Type:"DN"},
{"OriginId" : "2" , Qty:-3 , Type:"IM"},
]
}]
}
EG: I have "ProductLot" : ObjectId("5462dbd9599e5c200e000000") present in array so it should update qty 0 to 1; however, "ProductLot" : ObjectId("5462dbd9599e5c200e00000a") is not available in array so that should append a new element to the array.
PHP code, which is not updating creating appending array at every time:
$inventoryId = new \MongoId($_POST["inventoryid"]);
$productLotId = new \MongoId($invlotid);
$originId = $_POST['id'];
//$lotcontent = [ /* whatever this looks like */ ];
$lotcontent = array(
'Qty' => $invqty,
'ProductLot' => new \MongoId($invlotid),
'Product'=>$invproduct,
'Movement'=> array(
array(
'OriginId' => $_POST['id'],
'Qty' => $invqty,
'Type'=> 'DN',
), )
);
$invcolname = 'Inventory';
$result = $mongo->$dbname->$invcolname->update(
// Match an inventory without the specific ProductLot/OriginId element
array(
'_id' => $inventoryId,
'Lot' => array(
'$not' => array(
'$elemMatch' => array(
'ProductLot' => $productLotId,
//'OriginId' => $originId,
),
),
),
),
// Append a new element to the Lot array field
array('$push' => array( 'Lot' => $lotcontent ))
);
$movementcontent = array(
'OriginId' => $_POST['id'],
'Qty' => $invqty,
'Type'=> 'DN',
);
$result = $mongo->$dbname->$invcolname->update(
// Match an inventory without the specific ProductLot/OriginId element
array(
'_id' => $inventoryId,
'Lot' => array(
//'$not' => array(
'$elemMatch' => array(
'ProductLot' => $productLotId,
'Movement'=>array(
'$not' => array(
'$elemMatch' => array(
'OriginId' => $originId,
)
)
)
),
// ),
),
),
// Append a new element to the Lot.Movement array field
array('$push' => array( 'Lot.$.Movement' => $movementcontent ))
);
$result = $mongo->$dbname->$invcolname->update(
// Match an inventory with a specific ProductLot/OriginId element
array(
'_id' => $inventoryId,
'Lot' => array(
'$elemMatch' => array(
'ProductLot' => $productLotId,
//'OriginId' => $originId,
'Movement'=>array(
'$elemMatch' => array(
'OriginId' => $originId,
)
)
),
),
),
// Update the "Qty" field of the first array element matched (if any)
//array( '$set' => array( 'Lot.$.Qty' => 'Updated' )),
array( '$set' => array( 'Lot.$.Movement.$.Qty' => $invqty )),
array('upsert' => true));
Please anyone help me to resolve this?
Using $addToSet is problematic in this case, because the following lot elements would be considered different:
{
"Qty" :0,
"ProductLot" : ObjectId("5462dbd9599e5c200e000003"),
"Product" : ObjectId("543ca7be4cf59d400c000004"),
"OriginId" : "266"
}
{
"Qty" :5,
"ProductLot" : ObjectId("5462dbd9599e5c200e000003"),
"Product" : ObjectId("543ca7be4cf59d400c000004"),
"OriginId" : "266"
}
The first element is likely what you would be adding (either with quantity 0 or 1), and the second element would be the same logical lot element, just with an incremented quantity. If the latter element already existed in the array, I imagine you'd like for your application to increment the quantity from 5 to 6 instead of adding the first element, which is essentially a duplicate.
We definitely need two updates here, but I would propose the following:
// Let's assume the following identifiers...
$inventoryId = new MongoId($_POST['inventoryid']);
$productLotId = new MongoId($invlotid);
$originId = new MongoId($_POST['id']);
$lotcontent = [ /* whatever this looks like */ ];
$result = $collection->update(
// Match an inventory without the specific ProductLot/OriginId element
[
'_id' => $inventoryId,
'Lot' => [
'$not' => [
'$elemMatch' => [
'ProductLot' => $productLotId,
'OriginId' => $originId,
],
],
],
],
// Append a new element to the Lot array field
[ '$push' => [ 'Lot' => $lotcontent ] ]
);
MongoCollection::update() will return a result document with an n field indicating the number of affected documents. Since we aren't using the multiple option and are also matching at most one document by _id, we can expect n to be either 0 or 1. If n was 0, we either couldn't find an inventory document with that _id or we found one but it already had a Lot element with the product and origin identifiers (i.e. our $elemMatch criteria matched something, invalidating our negation). If n was 1, that means we found the inventory document, it did not contain a matching Lot element, and we appended it (i.e. our job is done).
Assuming n was 0, we should issue another update and attempt to increment the quantity:
$result = $collection->update(
// Match an inventory with a specific ProductLot/OriginId element
[
'_id' => $inventoryId,
'Lot' => [
'$elemMatch' => [
'ProductLot' => $productLotId,
'OriginId' => $originId,
],
],
],
// Update the "Qty" field of the first array element matched (if any)
[ '$inc' => [ 'Lot.$.Qty' => 1 ] ]
);
Here, I'm using the $ positional update operator to access a specific array element that was matched in the criteria. This allows us to craft an $inc without worrying about the index of the matched element.
Again, we can check $result['n'] here. If it's still 0, then we can assume that no document matches our _id (a completely separate error). But if n is 1 at this point, we successfully incremented the quantity and our job is done.
