PHP 2-d associative array: to add a key-value pair to the 2nd dimension -


i have 2 arrays these:

$a = ( 0 => ( 'name'=> 'leonardo' ), 1 => ('name'=> 'matthew' ), ... ); $b = ( 40, 50, ...);

and want produce third array:

$c = ( 0 => ('name' => 'leonardo', 'age' => 40), ('name' => 'matthew', 'age' => 50), ...);

what's array function that?

you can use array_map. works - 

$res =  array_map(function($a,$b){$a['age'] = $b;return $a;}, $a,$b); var_dump($res); /** output **/ array   0 =>      array       'name' => string 'leonardo' (length=8)       'age' => int 40   1 =>      array       'name' => string 'matthew' (length=7)       'age' => int 50
