php - Simple way to get only non-numeric keys from an array -

so have php array so:

array ( [0] => array ( [offset] => 1 [0] => 1 [name] => value:990937970 [1] => value:990937970 ) [1] => array ( [offset] => 2 [0] => 2 [name] => value:482758260 [1] => value:482758260 ) [2] => array ( [offset] => 3 [0] => 3 [name] => value:2045053536 [1] => value:2045053536 ) )

but want alter numeric keys not returned, this:

array ( [0] => array ( [offset] => 1 [name] => value:990937970 ) [1] => array ( [offset] => 2 [name] => value:482758260 ) [2] => array ( [offset] => 3 [name] => value:2045053536 ) )

my question: there simple way (without foreach or while loop) strip out these numeric keys?

i know can foreach check if $key string; however, loops add together code's cyclomatic complexity trying avoid them.

well, if really don't want utilize foreach, can do:

array_walk($data, function (&$v) { $keys = array_filter(array_keys($v), function($k) {return !is_int($k);}); $v = array_intersect_key($v, array_flip($keys)); });

array_walk() still looping foreach would; isn't explicitly shown.

also, mario said, modifying database query much recommended course of study of action this. if must on php side, foreach lot more efficient.
