I have two two-dimensional arrays like
Array
(
[0] => Array
(
[0] => 2022-01-19
[1] => 6
)
[1] => Array
(
[0] => 2022-01-20
[1] => 1
)
[2] => Array
(
[0] => 2022-01-21
[1] => 1
)
[3] => Array
(
[0] => 2022-01-22
[1] => 2
)
)
and
Array
(
[0] => Array
(
[0] => 2022-01-17
[1] => 6
)
[1] => Array
(
[0] => 2022-01-18
[1] => 1
)
[2] => Array
(
[0] => 2022-01-21
[1] => 1
)
[3] => Array
(
[0] => 2022-01-23
[1] => 2
)
)
I need to merge them on related date values and I want the following result:
Array
(
[0] => Array
(
[0] => 2022-01-17
[1] => 0
[2] => 6
)
[1] => Array
(
[0] => 2022-01-18
[1] => 0
[2] => 1
)
[2] => Array
(
[0] => 2022-01-19
[1] => 6
[2] => 0
)
[3] => Array
(
[0] => 2022-01-20
[1] => 1
[2] => 0
)
[4] => Array
(
[0] => 2022-01-21
[1] => 1
[2] => 1
)
[5] => Array
(
[0] => 2022-01-22
[1] => 2
[2] => 0
)
[6] => Array
(
[0] => 2022-01-23
[1] => 0
[2] => 2
)
)
I tried with the below code but not any success.
$final_array = [];
foreach ($openTicket as $val) {
$closeTicketNo = 0;
foreach ($closeTicket as $value) {
if ($val[0] == $value[0]) {
$closeTicketNo = $value[1];
}
}
$final_array[] = [$val[0], $val[1], $closeTicketNo];
}
I get all the elements from the $openTicket but not get all the elements from a $closeTicket to my result array $final_array
This code first finds all of the unique dates (using array_unique
) from the first values in each array (array_column
fetches the values and array_merge
puts them into 1 array).
Then it indexes each array by the dates (using array_column
again).
Finally looping through the unique dates and adding a new element to the output with the values (using ?? 0
so that if no value is present the array is still filled properly)...
$dates = array_unique(array_merge(array_column($openTicket, 0), array_column($closedTicket, 0)));
$open = array_column($openTicket, 1, 0);
$closed = array_column($closedTicket, 1, 0);
$finalArray = [];
foreach ($dates as $date) {
$finalArray[] = [$date, $open[$date] ?? 0, $closed[$date] ?? 0];
}
