@temp_array is two dimensional.

If your array is an array of rows, each row containing two columns, it should be something like

@array = (
    [ 1, 2 ],
    [ 3, 4 ],
    [ 2, 5 ],
);

Now, if you want to find the row that contains the values 3, 4

$temp   = 3;
$temp_1 = 4;
@matching_rows = grep { $_->[0] == $temp && $_->[1] == $temp_1 } @arra
+y;

With the above @array the resulting array consists of one element, which is an anonymous array containing the values 3 and 4. See perlref and perlreftut for the [ ] constructor.
