I'm trying to filter a multidimensional array and return the number of entries found for a given category.
EDIT
I'm trying to avoid any use of foreach. Right now looking into using array_intersect but getting array to string conversion error. I'm doing this :
//filter array with category name
$category_array = array('T-Shirt','Men');
$filter_category = (array_intersect($products['result'], $category_array));
var_export($filter_category);//return data of filtered entries
echo $row_count=count($filter_category);//return number of entries
The desired result should return the exact same array seen below but only with filtered entries. If there is a better way to do what I'm trying to do. I'm opened!
This is what the data looks like unfiltered

Something like this:
$category_array = array('T-Shirt', 'camo');
print_r(
array_intersect_key(
$products['result'],
preg_grep(
'/(?=.*\b'.implode('\b)(?=.*\b', $category_array).'\b)/i',
array_column($products['result'], 'name')
)
)
);
Output:

They all contain "Men" so I am not sure what the filter rules should be. Anyway, I used "camo" instead, after some tweaks.
PS, if you want to update the array then just do this instead of print_r:
$products['result'] = array_intersect_key( ... other code ... );
I can explain how it works if you want me too.
