php - Merging combining arrays if certain key/values matches in an array -

let's have array looks this:

array (     [0] => array         (             [id] => 44091             [epid] => 109912002             [makes] => honda             [models] => civic             [years] => 2000             [trims] =>             [engines] => 1.6l 1590cc 97cu. in. l4 gas sohc naturally aspirated             [notes] =>          )      [1] => array         (             [id] => 77532             [epid] => 83253884             [makes] => honda             [models] => civic             [years] => 2000             [trims] =>             [engines] => 1.6l 1595cc l4 gas dohc naturally aspirated             [notes] =>          )      [2] => array         (             [id] => 151086             [epid] => 109956658             [makes] => honda             [models] => civic             [years] => 1999             [trims] =>             [engines] => 1.6l 1590cc 97cu. in. l4 gas sohc naturally aspirated             [notes] =>          ) ) 

and somehow merge/group/combine whatever call if specific key/value pairs matching.

so condition be:

if makes & models & years & trims same, combine 1 array. other key/values such id/epid/trims/engines/notes not relevant , if possible can use/inherit 1 of matched entries.

once that's possible want add condition this:

if makes & models & years & trims & engines same combine 1 array.

perhaps i'm confusing myself , both can using same code.

anyways in situation expect outcome afterwards:

array (     [0] => array         (             [id] => 44091             [epid] => 109912002             [makes] => honda             [models] => civic             [years] => 2000             [trims] =>             [engines] => 1.6l 1590cc 97cu. in. l4 gas sohc naturally aspirated             [notes] =>          )      [1] => array         (             [id] => 151086             [epid] => 109956658             [makes] => honda             [models] => civic             [years] => 1999             [trims] =>             [engines] => 1.6l 1590cc 97cu. in. l4 gas sohc naturally aspirated             [notes] =>          ) ) 

notice array years of 1999 not merged.

i tried messing array_unique, array_flip couldn't work.

if matters i'm using php 5.6.7.

hope knows i'm talking about.

thanks.

echo '<pre>'; foreach($name_of_your_array $k=>$v){     $sorted_array["$v[makes]$v[models]$v[years]$v[trims]"]=$v; } $sorted_array=array_values($sorted_array); print_r($sorted_array); 

output:
