PHP - Merge duplicate array keys in a multidimensional array
I have have something similar to this, and Arrays go on for over 100 elements.
Array
( [0] => Array ([id] => 16
[data] => Array
(
[title] => Array
(
[label] => Title
[raw] => Product green
[value] => Product green
)
[image] => Array
(
[label] => Image
[files] => Array
(
[0] => mydirectory/product-pink.jpg
)
)
[productfamily] => Array
(
[label] => Product Family
[raw] => 103
[value] => Product 01
)
)
)
[1] => Array
(
[id] => 17
[data] => Array
(
[title] => Array
(
[label] => Title
[raw] => Product green
[value] => Product green
)
[image] => Array
(
[label] => Image
[files] => Array
(
[0] => mydirectory/product-green.jpg
)
)
[productfamily] => Array
(
[label] => Product Family
[raw] => 103
[value] => Product 01
)
)
)
now i would like to "group" only the arrays with the same [productfamily] so i can output the different pictures into a same group. What method would you recommand me to use? Some code hints would be greatly appreciated.
