sort array

[poe]

if i have an array like:

 

Array

(

    [0] => Array( [id] => 64, [zone] => a, => blue )

    [1] => Array( [id] => 17, [zone] => b, => grey )

    [2] => Array( [id] => 232, [zone] => c, => yellow )

    [3] => Array( [id] => 36, [zone] => a, => red )

    [4] => Array( [id] => 178, [zone] => a, => white )

    [5] => Array( [id] => 10, [zone] => c, => blue )

    [6] => Array( [id] => 115, [zone] => a, => orange )

    [7] => Array( [id] => 345, [zone] => a, => black )

    [8] => Array( [id] => 19, [zone] => b, => green )

    [9] => Array( [id] => 206, [zone] => a, => red )

)

 

 

i want to show items with the following criteria:

only 'zone' a,

4 highest ranked based on 'id' (highest to lowest)

 

so my result will be:

 

[7] => Array( [id] => 345, [zone] => a, => black )

[9] => Array( [id] => 206, [zone] => a, => red )

[4] => Array( [id] => 178, [zone] => a, => white )

[6] => Array( [id] => 115, [zone] => a, => orange )

 

thanks
