[RESOLVED] add items to existing array

[nuttynibbles]

hi, i got any array:

$arrname = array('1234'=>'chris', '5678'=>'john');

to add a item to an existing array, it can be done this way:
$arrname['9101']='mary'
$arrname['1213']='foo';

//printout
Array
(
[1234] => chris
[5678] => john
[9101] => mary
[1213] => foo
)

however, if i add items dynamically, like this it wont work:

function uniqueid($str,$hashstring)
{
$hash=md5($str.$hashstring);
return $hash;
}
$hash=uniqueid(date('Y-m-d h:i:s:u'),'key');

$arrname[$hash]=date('Y-m-d h:i:s:u');
//printout
Array
(
[1234] => chris
[5678] => john
[9101] => mary
[1213] => foo
[aa3b94089747eaf8177cd60c22a51542] => 2008-10-07 12:46:20:000000
)

then each time i print out, it will not add an additional key with its value. Instead, it overwrite the last key and value:
//printout
Array
(
[1234] => chris
[5678] => john
[9101] => mary
[1213] => foo
[7ecb2c22ccfd893800e9932b0df2cb38] => 2008-10-07 12:48:29:000000
)

My obj is to add items into the array using unique key with some value like this:
Array
(
[1234] => chris
[5678] => john
[9101] => mary
[1213] => foo
[aa3b94089747eaf8177cd60c22a51542] => 2008-10-07 12:46:20:000000
[7ecb2c22ccfd893800e9932b0df2cb38] => 2008-10-07 12:48:29:000000
)

how should i do this?

The $arr = array{...} expression completely overwrites the contents of the array. To add an item you need to use one of the following:

//initalize array:
$array = array('foo', 'bar');

// add element with specific key:
$array['new'] = 'another element';

// add element using next available numeric index:
$array[] = 'yet another element'

Also see [man]array_unshift/man and [man]array_push/man, though I suspect neither of them is needed for this.
