$array1=$array3=array(1,2,3,4,5,6,

array('new delhi','mumbai','kolkata'));

echo"<br/><b>Value of original array is:</b><br/>";

print_r($array1);

$array2=array('a','b','c');

array_push($array1,$array2);

echo"<br/><b>After appending an array:</b><br/>";

print_r($array1);

$var="new variable";

echo"<br/><b>After appending a value:</b><br/>";

array_push($array1,$var);

print_r($array1);

echo"<br/><b>After appending to itself :</b><br/>";

array_push($array3,$array3);

print_r($array3);

Output:

Value of original array is:
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => Array
        (
            [0] => new delhi
            [1] => mumbai
            [2] => kolkata
        )

)

    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => Array
        (
            [0] => new delhi
            [1] => mumbai
            [2] => kolkata
        )

    [7] => Array
        (
            [0] => a
            [1] => b
            [2] => c
        )

)

After appending a value:
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6

            [1] => mumbai
            [2] => kolkata
        )

            [1] => b
            [2] => c
        )

    [8] => new variable
)

After appending to itself :
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => Array
        (
            [0] => new delhi
            [1] => mumbai
            [2] => kolkata
