[RESOLVED] array only queries out the last key and value in a foreach statement

numerical25

for some reason, the array i made only queries out the last value in the foreach statement like example below

	$message = array('hello'=>'there');
	$message = array('hello'=>'there');
	$message = array('hello'=>'there');
	$message = array('hello'=>'there');

foreach ($message as $key => $value) {
	echo $key." ".$value;
}

it only queries out hello there once. what am i doing wrong ???

because your array only has one key value pair. $message = is just overwriting the previously defined $message.

So what you apparently want is a 2-dimension array:

$message = array(
   array('hello'=>'there'),
   array('hello'=>'there'),
   array('hello'=>'there'),
   array('hello'=>'there')
);

So let me just get this straight so I can have a better understanding of arrays. Are you saying that the varible $message is actually a key value ?? I thought it was just a varible that store multiple key values. so doing this

$message = array('hello' => 'value');

is the samething as doing this

$hello = array('value')

except its encapsulated inside of the varible $message ?????

Now this the code im using

	$message = array(array('hello'=>'there'));
	$message = array(array('hello2'=>'there'));
	$message = array(array('hell03'=>'there'));
	$message = array(array('hello4'=>'there'));

foreach ($message as $key => $value) {
	echo $key." ".$value;
}

but this is the output

0 : Array 0 Array

.. but you need to do is to do something like NogDog suggested:

$message = array(array('hello'=>'there'),
    array('hello'=>'there'),
	array('hello'=>'there'),
	array('hello'=>'there'));

foreach ($message as $key => $value) {
    //echo $key." ".$value;//this will list out only first array dimension, 
//but to get an actual values you need to scope the second dimension like this:
		while(list($k,$v) = each($value)){
			echo "$k $v<br />";
		}
    }

Your way of creating array only rewrites array so you end up with one member in the end and it is in second dimension...
Hence the 0 Array... That just means that you have another array stashed under the key 0... Are array clearer now?

numerical25

Yes I understand now BUT....

what if I have a Class that contains a array... and the only way you can add a key and value to this array is through a function.

How would i go about doing that ? I just cant leave the array parenthesis open.

bodzan

You always can create a two dimensional array this way as well:

$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');
$message[] = array('hello'=>'there');

This way you would get the same array as in the previous example...

ok thanks!!
