How to count more than one items in array_column? - php

Question

I asked a question called 'How to count items in an array that's in an array?' and now I need help on expanding from that question.
How do you count items in two arrays?
My array looks like this:
Array
(
[0] => Array
(
[acf_fc_layout] => irl_today_website_entry
[irl_today_website] => Array
(
[0] => Array
( data removed)
[1] => Array
( data removed )
)
)
[1] => Array
(
[acf_fc_layout] => irl_today_social_entry
[irl_today_social] => Array
(
[0] => Array
( data remove )
[1] => Array
( data remove)
)
)
)
And I use:
<?php $arrays = get_field('irl_today_entry');
$res = array_map(function($x) {
return count($x);
}, array_column($arrays, 'irl_today_website'));?>
to count items in [irl_today_social]. How do I count items in [irl_today_social] and [irl_today_website]?
I tried array_column($arrays, "irl_today_social", "irl_today_website") and it only counted items in [irl_today_social]

Answer 1

array_map() can be fed multiple arrays to work with. The first array "irl_today_social" elements are referenced by $x, the second "irl_today_website" by $y in this case.
Use following:
$res = array_map(function($x, $y) {
$soc = count($x);
$web = count($y);
return ['soc' => $soc, 'web' => $web];
}, array_column($arrays, "irl_today_social"), array_column($arrays, "irl_today_website"));
array_map() will return an array with the count for each - the result sample output:
Array
(
[0] => Array
(
[soc] => 2
[web] => 3
)
)
