Thought I will point out first that I have looked around on Stackoverflow and the internet already and although they are plenty of examples none of them are explained into such a way for me to understand how to convert the code to work with my array structure.
I believe I need to use one of the functions uksort or uasort but unsure on this as well.
My array looks like the following.
Array
(
[0] => Array
(
[Result] => Array
(
[id] => 260
[event_id] => 72
[year] => 2010
[york_score] => 27
[york_points] => 0.0
[lancs_score] => 51
[lancs_points] => 4.0
[winner] => L
[confirmed] => Y
[updated] => 2010-05-01 16:10:03
)
[Event] => Array
(
[id] => 72
[sport_id] => 25
[event_title] => 1st Team
[Sport] => Array
(
[id] => 25
[sport_title] => Netball
)
)
)
And where its [0] means it continues on.
I need to sort all of the arrays [0,1,2,3,...] by the sport_title key found in [Event][Sport]
Does anyone know how to create a sorting function to do this?
Some explanation of how the function is working would also be helpful if I later need to adapter/alter the code to work else where on my site.
Where $array is the name of the array which holds the array you posted in your question.
function sort_multi($item_1, $item_2)
{
// strcmp looks at two strings and, based off the characters' and their order,
// determines which one is numerically greater. When this function returns a
// negative, for example, it means the first item it's comparing is less that the
// second item (ef and eg, for example). The usort function then rearranges
// the array based off these comparisons.
return strcmp($item_1['Event']['Sport']['sport_title'], $item_2['Event']['Sport']['sport_title']);
}
usort($array, 'sort_multi');
