Description | Author | |
This class can combine arrays finding intersections. Innovation Award
|
Combines arrays by searching for intersections and adding them to the master array. Keys are combined using a delimiter.
use Jelle_S\Util\Combiner\ArrayKeyCombiner;
// Search this array of arrays for intersections and extract them, using a
// delimiter to combine the keys. Limit the number of iterations to search for
// intersections to 10.000, limit the minimum size of intersections to 3, set
// the key delimiter to a comma.
$arrays = array(
array(
'a' => 1,
'b' => 2,
'c' => 3,
'd' => 4,
'e' => 9,
),
array(
'a' => 1,
'b' => 2,
'c' => 3,
'e' => 9,
),
array(
'a' => 1,
'b' => 42,
'c' => 3,
'd' => 4,
),
array(
'b' => 42,
'c' => 3,
'a' => 1,
),
array(
'z' => 26,
'e' => 9,
'a' => 1,
),
);
$combiner = new Jelle_S\Util\Combiner\ArrayKeyCombiner($arrays, 3, 10000, ',');
print_r($combiner->combine());
Output:
Array
(
[4] => Array
(
[a] => 1
[e] => 9
[z] => 26
)
[0,1] => Array
(
[a] => 1
[b] => 2
[c] => 3
[e] => 9
)
[2,3] => Array
(
[a] => 1
[c] => 3
[b] => 42
)
[2,0] => Array
(
[d] => 4
)
)
The 'a' and 'z' keys of the array with key '4' were not combined because the threshold for combinations is 3, and combining them would result in a combined array with only two elements.
The arrays with keys '2' and '0' were combined because after extracting the combinations, these two arrays were identical, and the threshold has no effect for identical arrays, they are always combined.
