How about:

$arr1 = Array(
    Array(
        'did'       => 1,
        'dname'     => 'AJAy',
        'dsp'       => 3,
        'dqu'       => 'abc',
        'isactive'  => 'Y',
    ),
    Array(
        'did'       => 2,
        'dname'     => 'Vijay',
        'dsp'       => 4,
        'dqu'       => 'abc',
        'isactive'  => 'Y',
    ),
);
$arr2 = Array(
    Array(
        'recno'     => 2,
        'dname'     => 'Vijay',
        'dsp'       => '',
        'did'       => '',
        'dqu'       => '',
        'isactive'  => 'Y',
    ),
    Array(
        'recno'     => 1,
        'dname'     => 'AJAy',
        'dsp'       => '',
        'did'       => '',
        'dqu'       => '',
        'isactive'  => 'Y',
    ),
);

for($i1=0; $i1<count($arr1); $i1++) {
    for ($i2=0; $i2<count($arr2); $i2++) {
        if ($arr1[$i1]['dname'] == $arr2[$i2]['dname']) {
            $arr2[$i2]['did'] = $arr1[$i1]['did'];
            $arr2[$i2]['dsp'] = $arr1[$i1]['dsp'];
            $arr2[$i2]['dqu'] = $arr1[$i1]['dqu'];
        }
    }
}
print_r($arr2);

output:

Array
(
    [0] => Array
        (
            [recno] => 2
            [dname] => Vijay
            [dsp] => 4
            [did] => 2
            [dqu] => abc
            [isactive] => Y
        )

    [1] => Array
        (
            [recno] => 1
            [dname] => AJAy
            [dsp] => 3
            [did] => 1
            [dqu] => abc
            [isactive] => Y
        )
