PHP Array_Sum no array multidimensional
Se eu tenho uma matriz multi dimensional em PHP assim ...
[0] => Array
(
[url] => http://domain1.com
[domain] => domain1.com
[values] => Array
(
[character_length] => 25
[word_count] => 7
)
)
[1] => Array
(
[url] => http://domain2.com
[domain] => domain2.com
[values] => Array
(
[character_length] => 30
[word_count] => 7
)
Como posso fundi-los para produzir ....
[0] => Array
(
[url] => *can be anything*
[domain] => *can be anything*
[values] => Array
(
[character_length] => 55
[word_count] => 14
)
)
