How can I get unique pair combinations of arrays from sample matrix array - php

I have the following Matrix array:
$sampleMatrix = [
[ ['user1', 'user2'], ['user1', 'user3'], ['user1', 'user4'], ['user1', 'user5'], ['user1', 'user6'] ],
[ ['user2', 'user3'], ['user2', 'user4'], ['user2', 'user5'], ['user2', 'user6'] ],
[ ['user3', 'user4'], ['user3', 'user5'], ['user3', 'user6'] ],
[ ['user4', 'user5'], ['user4', 'user6'] ],
[ ['user5', 'user6'] ]
];
I'm trying to get all the possible unique combinations in pairs, for example, for following matrix it will be like this:
$wantedArray= [
[ ['user1', 'user2'], ['user3', 'user4'], ['user5', 'user6'] ]
[ ['user1', 'user3'], ['user2', 'user5'], ['user4', 'user6'] ]
[ ['user1', 'user4'], ['user2', 'user6'], ['user3', 'user5'] ]
[ ['user1', 'user5'], ['user2', 'user4'], ['user3', 'user6'] ]
[ ['user1', 'user6'], ['user2', 'user3'], ['user4', 'user5'] ]
];
Prevent duplicate each user in the row.

Conditional sum in MongoDB

here is the Mysql Query:
SELECT name, sum(case when reason = 'fb' then score else 0 end) as fb, sum(case when reason = 'email' then score else 0 end) as email from multi_group group by name
I am trying to convert this query in MongoDb:
$query = Model::raw(function($collection) {
return $collection->aggregate([
[
'$group' => [
'_id' => [
'name'=>'$name',
'fb'=> [
'$cond'=> [
[ '$eq'=> ['$reason', 'fb']],
'$score',
0
]
],
]
],
]]);
});
any help would be highly appreciable.

It is not tested though but I believe this should be ok.
$query = Model::raw(function($collection) {
return $collection->aggregate([
[
'$group' => [
'_id' => [
'name'=>'$name',
]
'fb' => ['$sum' =>
[
'$cond'=> [
[ '$eq'=> ['$reason', "fb"]],
'$score',
0
]
]
],
'email'=> [ '$sum' =>
[
'$cond'=> [
[ '$eq'=> ['$reason', "email"]],
'$score',
0
]
]
]
]
],
]);
});

i just changed 0 to 1 and it worked
$query = Model::raw(function($collection) {
return $collection->aggregate([
[
'$group' => [
'_id' => [
'name'=>'$name',
]
'fb' => ['$sum' =>
[
'$cond'=> [
[ '$eq'=> ['$reason', "fb"]],
'$score',
1
]
]
],
'email'=> [ '$sum' =>
[
'$cond'=> [
[ '$eq'=> ['$reason', "email"]],
'$score',
1
]
]
]
]
],
]);
});

Remove multidimensional array with empty sub arrays using PHP

I have this array as follows. Every student has 7 arrays starting from Monday to Sunday and inner array of each has events for day
$array = [
'Alex' => [
[
['event' => 'eventName1'],['event' => 'eventName2']
],
[
['event' => 'eventName3'],['event' => 'eventName4']
],
[
['event' => 'eventName5'],['event' => 'eventName6']
],
[
['event' => 'eventName7'],['event' => 'eventName8']
],
[],
[],
[]
],
'christoper'=>[
[],[],[],[],[],[],[]
]
];
The output array should be
[
'Alex' => [
[
['event' => 'eventName1'],['event' => 'eventName2']
],
[
['event' => 'eventName3'],['event' => 'eventName4']
],
[
['event' => 'eventName5'],['event' => 'eventName6']
],
[
['event' => 'eventName7'],['event' => 'eventName8']
],
[],
[],
[]
]
];
I have tried this
$array = array_filter(array_map('array_filter', $array));
but the result is vain. Can anyone help me in getting desired output. I want to filter out students with no events

You can do this:
<?php
$output = array_filter($array, function (array $studentDays) {
foreach ($studentDays as $day) {
// if there is a *non-empty* day, we return early and keep the whole record
if (! empty($day)) {
return true;
}
}
// only empty days, so discard the record
return false;
});
https://3v4l.org/AkshS

Loop over array and apply array_filter
$array = [
'Alex' => [
[
['event' => 'eventName1'],['event' => 'eventName2']
],
[
['event' => 'eventName3'],['event' => 'eventName4']
],
[
['event' => 'eventName5'],['event' => 'eventName6']
],
[
['event' => 'eventName7'],['event' => 'eventName8']
],
[],
[],
[]
],
'christoper'=>[
[],[],[],[],[],[],[]
]
];
foreach( $array as $key => $value ){
$array[$key] = array_filter($value);
}
print_r( $array );

A recursive call to array_filter will do the job; in the outer call we check the size of the returned array to decide whether to keep that element or not (it will be 0 if the array consisted solely of empty arrays, as it does for 'christopher'):
$array = array_filter($array, function ($v) { return count(array_filter($v)); });

Elasticsearch query with multiple attributs and values

I try to construct, in php, an query with different attribut:
this following code work :
$searchParams = [
'body' => [
"from"=> 0,
"size"=> 30000,
'query' => [
'filtered'=> [
'filter' => [
'bool' => [
'must' => [
'terms' => [
'field_support' => [105,106,1896,1897]
]
]
]
]
]
]
]
];
But when i add "term" it's not working:
$searchParams = [
'body' => [
"from"=> 0,
"size"=> 30000,
'query' => [
'filtered'=> [
'filter' => [
'bool' => [
'must' => [
'terms' => [
'field_support' => [105,106,1896,1897]
],
'term' => [
'title' => ["le jeu de la dame"]
]
]
]
]
]
]
]
];
I don't understand why it's doesn't works.
Can somebody help me ? Thanks

You need to surround your terms and term query with another associative array, like this:
$searchParams = [
'body' => [
"from"=> 0,
"size"=> 30000,
'query' => [
'filtered'=> [
'filter' => [
'bool' => [
'must' => [
[
'terms' => [
'field_support' => [105,106,1896,1897]
]
],
[
'term' => [
'title' => ["le jeu de la dame"]
]
]
]
]
]
]
]
]
];
UPDATE
Variant with match
$searchParams = [
'body' => [
"from"=> 0,
"size"=> 30000,
'query' => [
'filtered'=> [
'query' => [
'match' => [
'title' => ["le jeu de la dame"]
]
],
'filter' => [
'terms' => [
'field_support' => [105,106,1896,1897]
]
]
]
]
]
];

ElasticSearch match query multiple terms PHP

I am trying to construct must query on multiple terms, the array looks like this:
$params = [
'body' => [
'query' => [
"bool" => [
"must" => [
"terms" => [
"categories" => [
"Seating",
],
],
"terms" => [
"attributes.Color" => [
"Black",
],
]
],
"filter" => [
"range" => [
"price" => [
"gte" => 39,
"lte" => 2999,
],
],
],
],
],
'from' => 0,
'size' => 3,
],
];
Which is represented in JSON like this:
{
"query": {
"bool": {
"must": {
"terms": {
"attributes.Color": ["Black"]
}
},
"filter": {
"range": {
"price": {
"gte": "39",
"lte": "2999"
}
}
}
}
},
"from": 0,
"size": 3
}
The problem is, JSON objects are represented as arrays in PHP so if I setup key for one array, it is rewritten. Do you have any idea on how to create multiple terms query in PHP?
Thanks in advance.

You need to add an additional array to enclose all your terms queries
$params = [
'body' => [
'query' => [
"bool" => [
"must" => [
[
"terms" => [
"categories" => [
"Seating",
],
]
],
[
"terms" => [
"attributes.Color" => [
"Black",
],
]
]
],
"filter" => [
"range" => [
"price" => [
"gte" => 39,
"lte" => 2999,
],
],
],
],
],
'from' => 0,
'size' => 3,
],
];

As you can see, the array looks something like this:
[0]
[0]
[0]
[0] => coordinate 1 Latitude
[1] => coordinate 1 Longitude
.....
[40]
[0] => coordinate 41 Latitude
[1] => coordinate 41 Longitude
[1]
[0]
[0]
[0] => coordinate 1 Latitude
[1] => coordinate 1 Longitude
.....
[385]
[0] => coordinate 386 Latitude
[1] => coordinate 386 Longitude
[1]
[0]
[0] => coordinate 1 Latitude
[1] => coordinate 1 Longitude
.....
[18]
[0] => coordinate 19 Latitude
[1] => coordinate 19 Longitude
I'm looking to to create a recursive function that will drill through a funky array like this and basically return me just coordinates in a multi-dimensional array with three sub items. I've tried a few things but didn't even come close.

Since I know for a fact that the deepest level of coordinates, I think this should do it...
function cleanArray($coords)
{
$toReturn = array();
foreach ($coords as $thisCoords)
{
foreach ($thisCoords as $finalCoords)
{
$testArray = $finalCoords[0];
$lastArray = $finalCoords;
while (is_array($testArray[0]))
{
$lastArray = $testArray;
$testArray = $testArray[0];
}
$toReturn[] = $lastArray;
}
}
return $toReturn;
}
