I have an array like below, and I want to do the total of values in a specific manner where all values of ADDED_NEW_(.*) {regular expressions}, and similarly other values. I have only specific vals like ADDED_NEW, ADDED_OLD, and ADD_LATER.
My array is like:
$stats = Array
(
[ADDED_NEW_2012_06_12] => 16
[ADDED_OLD_2012_06_12] => 10
[ADD_LATER_2012_06_12] => 12
[ADDED_NEW_2012_06_11] => 16
[ADDED_OLD_2012_06_11] => 10
[ADD_LATER_2012_06_11] => 12
)
Can you please tell me how can i obtain my result. I don't know how to add such values using regex in php. Please help.
The output I am expecting is $ADDED_NEW = 32 (i.e. 16+16), $ADDED_OLD = 20 (i.e. 10+10) and $ADD_LATER = 24 (i.e. 12+12)
