Ben aynı şekilde bu diziler var:

0 => Array ( [0] => Finance / Shopping / Food, [1] => 47 )            
1 => Array ( [0] => Finance / Shopping / Food, [1] => 25 )                 
2 => Array ( [0] => Finance / Shopping / Electronic, [1] => 190 ) 

I need to create one array with [0] as a key and [1] as value.
The tricky part is that if the [0] is same it add [1] to existing value.

Yani istediğiniz sonucu:

array ([Finance / Shopping / Food]=> 72, [Finance / Shopping / Electronic] => 190);

teşekkürler
