Given the following array $mm
Array
(
[147] => Array
(
[pts_m] =>
[pts_mreg] => 1
[pts_cg] => 1
)
[158] => Array
(
[pts_m] =>
[pts_mreg] =>
[pts_cg] => 0
)
[159] => Array
(
[pts_m] =>
[pts_mreg] => 1
[pts_cg] => 1
)
)
When I run count(array_filter($mm)) I get 3 as result since it is not recursive.
count(array_filter($mm), COUNT_RECURSIVE) also will not do because I actually need to run the array_filter recursively, and then count its result.
So my question is: how do I recursively run array_filter($mm) in this case?
My expected result here would be 4.
Please note that I am not using any callback so I can exclude false, null and empty.
Should work
$count = array_sum(array_map(function ($item) {
return ((int) !is_null($item['pts_m'])
+ ((int) !is_null($item['pts_mreg'])
+ ((int) !is_null($item['pts_cg']);
}, $array);
or maybe
$count = array_sum(array_map(function ($item) {
return array_sum(array_map('is_int', $item));
}, $array);
There are definitely many more possible solutions. If you want to use array_filter() (without callback) remember, that it treats 0 as false too and therefore it will remove any 0-value from the array.
If you are using PHP in a pre-5.3 version, I would use a foreach-loop
$count = 0;
foreach ($array as $item) {
$count += ((int) !is_null($item['pts_m'])
+ ((int) !is_null($item['pts_mreg'])
+ ((int) !is_null($item['pts_cg']);
}
Regarding the comment below:
Thx @kc I actually want the method to remove false, 0, empty etc
When this is really only, what you want, the solution is very simple too. But now I don't know, how to interpret
My expected result here would be 5.
Anyway, its short now :)
$result = array_map('array_filter', $array);
$count = array_map('count', $result);
$countSum = array_sum($count);
The resulting array looks like
Array
(
[147] => Array
(
[pts_mreg] => 1
[pts_cg] => 1
)
[158] => Array
(
)
[159] => Array
(
[pts_mreg] => 1
[pts_cg] => 1
)
)
