Code:

$str = 'asd-12sdf45-56asdf100';
function get_numerics ($str) {
        preg_match_all('/\d+/', $str, $matches);
        print_r( $matches);
    }
    get_numerics($str);

But I don't know how to get negative numbers "-12", "-56"

I have to print all values with one loop (IT DOESN'T NEED print_r[$array])
this is what i made til now but it isn't working properly

Code:

$array = array(
		array(11,12,13,14,15,16),
		array(21,22,23,24,25,26),
		array(31,32,33,34,35,36),
		array(41,42,43,44,45,46),
		array(51,52,53,54,55,56),
		array(61,62,63,64,65,66)
);


$colindex = 0;
$rowindex = 0;

i want to print 1,3,5 rows from 2d array. Can i use some kind of implode or loop?

$array = array(
array(11,12,13, 14,15,16),
array(21,22,23, 24,25,26),
array(31,32,33, 34,35,36),
array(41,42,43, 44,45,46),
array(51,52,53, 54,55,56),
array(61,62,63, 64,65,66)
);

I want it to look like this: "array row1: 11,12,13,14,15, 16"
